Changes Media Server 3.0.0

Overview

Please note: The DVBViewer Media Server 3.x contains major changes. Before using it, every DVBViewer in the network that is associated with the Media Server should be updated to version 7.x, because there may be compatibility issues with older DVBViewer 6.x versions. “Associated” means in this context, that DVBViewer Options → DVBViewer Media Server → Enable support for the DVBViewer Media Server is switched on and the Media Server in question is selected on this page.

A brief overview of the main changes:

  • Web Server: The server now accepts HTTPS connections, after being configured accordingly. The creation and usage of self-signed certificates is supported.

  • Web Interface: Several fixes and detail enhancements facilitate the usage of the desktop and mobile web interface. Tuner type icons in channel lists make it easier to recognize channels if more than one reception type (like satellite and terrestrial) is used.

  • Recording: Several measures enhance the usability of timer recordings, including the automatic creation of timers by EPG search mechanisms.

  • Streaming: The Media Server as streaming client supports MPEG Dash as new format. The support for HLS has been enhanced.

  • Miscellaneous: The Media Server automatically reloads the channel or favorites list at runtime if it detects that it has been changed by another program (DVBViewer or TransEdit). It is not necessary anymore to stop and restart the server for this.

Web Server

  • Added: Web Server: The server now accepts HTTPS connections, after being configured accordingly. Please note that this (and the following) does not apply to other server instances (Live Stream, Media Stream, UPnP, RTSP). Since the HTTPS includes encryption and authentication by certificates, some preparations are necessary:

    1. Port assignment: HTTPS requires a separate port, so that HTTP still works if the Web Server is configured for HTTPS. The HTTPS port can be entered on the Media Server Options → Web/UPnP page. The port number must be unused by other server instances within the Media Server and other servers running on the PC. The default is 8088.

    2. HTTPS Activation: The checkbox “Activate HTTPS” on the new “Media Server Options → HTTPS Settings” page enables HTTPS and lets the Media Server listen on the HTTPS port for incoming connections. Since the server needs less resources without HTTPS activation, it should only be used if necessary.

    3. Server key and certificate selection: HTTPS requires a key for encrypting data and a server certificate for proving its identity. Without it HTTPS remains disabled in the Web Server. The key and certificate file can be selected on the new Media Server Options → HTTPS Settings page. If the key and certificate are present in a single file, it must be specified in both input lines. The default files are serverkey.pem and servercert.pem in the new Certificates sub-directory of the DVBViewer Media Server installation directory. The initially installed files only enable HTTPS for “localhost” and 127.0.0.1, unless modified.

    4. Certificate creation: For modifying the pre-installed certificate the Media Server Options (svcoptions.exe) must be launched with admin rights (see Tray Tool menu → Configure with Admin Rights). This activates the “Certificate Creation” panel on the HTTPS Settings page.

    5. Password protection: On the “Create Certificate” panel you can optionally enter a password as additional security measure. It serves for encrypting the content of the key files, thus making them useless for an attacker who steals them.

    6. Add addresses: A multiline input field on the “Certificate Creation” panel allows to add IP addresses and domain names, that shall be accessible for Media Server clients with HTTPS (one per line, without protocol and port). A newly-created certificate is only valid for domains and addresses in the list. The “Add Local Addresses” button adds the computer name and all IP addresses to the list, under which the Media Server is accessible in the local (home) network.

    7. Create certificate: This button executes the batch file CreateHTTPSCertificates,bat. It uses OpenSSL to create a new server certificate (servercert.pem). Additionally, if the password has been changed, other relevant files are recreated. The previous files are renamed to *.bak. On a password change the Media Server Options will prompt for confirmation, because the CA root certificate (cacert.pem, CA = Certificate Authority) has to be re-installed on client devices. This file is used to sign the server certificate, thus confirming that it can be trusted. Since the Media Server Options also create the CA certificate, the server certificate is “self signed”, requiring another measure:

    8. Root certificate installation: After step 7 the Media Server is ready for HTTPS connections. However, since the issuer of the server certificate is unknown to clients, browsers and even the VLC will not trust it and display warnings. It can be avoided by installing the “Certificate Authority” (CA) certificate in the Windows store on the client PC: Click the “Certificate Folder” button and copy the files cacert.pem and InstallRootCertificate.bat to the client PC. Then execute the batch file with admin rights. Then restart browsers or other clients that are running on that PC. Please note that Firefox does not use the Windows store by default (recent versions can be configured for it), so cacert.pem has to be imported manually: Firefox Options → Privacy & Security → scroll down to the bottom → View Certificates → select Authorities tab → Import.

Installing the cacert.pem file lets Windows and clients trust all certificates that have been signed with this CA root certificate. The signing confirms that everything received from the Media Server (identifying itself with the signed server certificate) is originating from it and not from a “man in the middle” attacker. Step 8. can be avoided by not using self-signed certificates, but signing from a generally approved certification authority like Let's Encrypt, where you can get it for free, in contrast to commercial authorities like Verisign. The root certificates of such authorities are already present in the Windows store. However, the process always includes an (online) proof in one way or the other, that the domain for which the certificate is needed is under the server's control. Thus it is suitable for accessing the Media Server from the internet, but not for using it inside the home network.

By this it should be clear that certificates and encryption keys are security relevant. Keep them private like your identity card! Don't pass them to others, don't publish them. Delete certificate files where they are no more needed (particularly cacert.pem after installation on a client PC). Every bad guy that gets hold of your certificates (plus password, if set) can set up a HTTPS server that is trusted by your browser because it pretends to be the Media Server!

  • Added: HTTPS Options: Tweak “HTTPS Certificate validity period” (→ execute DMSTweaker.bat). It specifies the validity period of newly created HTTPS certificates in days, beginning with the time of creation. The default value 3652 equals 10 years.

  • Change: Network Libraries / OpenSSL: Network libraries have been updated for OpenSSL 1.1.x support. OpenSSL is required for encrypted connections via HTTPS. The setup adds new OpenSSL DLLs (libssl-1_1.dll and libcrypto-1_1.dll). They carry different names than the previously used OpenSSL 1.0.2 DLLs (ssleay32.dll and libeay32.dll). The Media Server preferably uses the new DLLs, if available, but is also able to work with the old ones.

Web Interface

  • Change: Web Interfaces / Channel List: TS Stream channels with a URL referring to the Media Server itself are hidden in the web interfaces, because they would require the Media Server to work as its own client, which is not possible. Additionally “play as file” entries in the channel list (supported by DVBViewer Pro 7.0.0 and later) are hidden, because they have no EPG and can't be recorded. However, there is one exception:

  • Added: Desktop Web Interface: Tweak “Show channel list file entries in Media -> TV/Radio” (→ launch DMSTweaker.bat). It specifies if “play as file” entries from the DVBViewer channel list are shown in the Web Interface → Media page → TV/Radio sections. The default is “off”. Switching it on enables

    • playing the items as transcoded stream in the browser.

    • passing the items as M3U playlist to other players, that shall play the original streams.

  • Added: Web Interfaces: Additional “Favorites Only” switch on the Search EPG page for limiting search results and auto timer creation to favorite channels. If no favorites are present, the “Favorites Only” switch has the same effect as the “All Channels” switch.

  • Change: Web Interfaces: The caption of the Delete button on the Search EPG page now changes to “Reset”, if the default settings are active and no specific search preset is selected. As before the button resets the special default settings for search and timer creation to the general default, as specified in the Media Server Options.

  • Fix: Web Interfaces: Selecting the “Select a search preset…” entry in the drop-down list on the Search EPG page (supposed to load the default settings) did not clear the “Search for” input line, so that a subsequent “Save” did not save the default settings, but created another search preset.

  • Added: Web Interfaces: Hint for File Naming Scheme input lines on the Search EPG page, Recorder Configuration page and in the Timer dialog). It enumerates the available placeholders. In the Desktop Web Interface the hint appears on mouse over, in the Mobile Web Interface after clicking the “File Naming Scheme” label.

  • Change: Web Interfaces: The Recorder Configuration page has partly been rearranged for consistency with the Recordings and Recording Timers pages in the DVBViewer and Media Server options.

  • Change: Web Interfaces: A tuner type icon for each channel entry is displayed in channellists, where possible. A small overlaid yellow key indicates encryption. A red cross icon on the Timers page indicates that no channel can be assigned to a recording timer, which means, it cannot be executed. Task timers appear with a clock icon.

  • Change: Web Interfaces: The “Change Log” link on the Links page has been renamed to “Release Notes”.

  • Fix: Desktop Web Interface: The attempt to delete a recording that was opened elsewhere flagged it in the recording database as “removed”, though the file could not be deleted. Additionally the Web Interface handled corresponding list items on the Recordings page inconsistently, depending on whether a selection of recordings via checkboxes or a single recording via Delete icon was deleted.

  • Added: Desktop Web Interface: Double-clicking a channel on the Channel EPG page plays it in the browser.

  • Change: Mobile Web Interface: Creating a new timer does not require to input a timer name anymore. If it is missing, the Media Server uses the channel name.

Recording

  • Change: Recording Options: The elements on the “Recordings” and “Recording Timers” pages (former “Recorder” and “Recordings”) have been re-sorted:

    • The Recordings page contains settings that are applied to recordings when they are started by the Media Server, including recordings that are sent by DVBViewer to the Media Server.

    • The Recording Timers page specifies default values for timer properties, that can be edited and changed per timer in the timer dialog of the web interface.

  • Added: Recording Timers Options: New Placeholders button. It opens a tool window that enumerates all placeholders that can be used in the File Naming Scheme. Double-clicking a placeholder or selecting it and pressing the Return key inserts it at the current position in the input line.

  • Change: Recorder: Enhanced synchronization between the channel and timer list. A channel auto-update immediately adjusts the corresponding channel assignment in timers. When reloading the channel list, the Media Server first equips all recording timers with copies from the previous channel list entries. After deleting the old and loading the new channel list it tries to replace the copies by links to new channel list entries, if possible. If not, the copies are preserved until the Media Server is stopped. This prevents wrong or missing channel assignments.

  • Added: Auto-Timer Creation: The Media Server now additionally stores the EPG title and subheading (if available) in each new set of timer data. They appear in the file svctimers.xml as <Title> and <Subheading> elements and are used to check automatically created timers against already existing timers, in order to deactivate duplicates. Previously the timer name was used for this purpose. Since it is composed by default of the EPG title plus “ - “ as separator plus the 50 first characters of the subheading, the check did not work as intended in some cases, because the title and subheading could not be reconstructed from the timer name, particularly if it was changed by the user.

  • Change: Auto-Timer Creation: The comparison of the EPG title and subheading for deactivating duplicates now only considers letters and digits. Differences concerning spaces, hyphens, punctuation marks etc. are ignored, so that they can’t affect the detection of repeated broadcast anymore.

Streaming

  • Added: TS Stream: Support for receiving MPEG Dash streams. Usually the URLs have the filename extension .mpd and refer to a XML manifest. The general handling is similar to HLS. Please note the following limitations:

    • Supported codecs are H.264 and HEVC video and AAC, AC3 and EAC3 audio.

    • The only supported container format is the mostly used segmented MP4 base media format, which is internally transcoded to TS. Some rarely used MPEG Dash options are omitted.

    • The current implementation does not support playing encrypted / DRM-protected streams.

  • Added: TS Stream: Support for HLS (HTTP Live Streaming) with

    • streams containing AC3 and EAC3 audio (previously only MP3 and AAC).

    • segments in MP4 base media format (previously only segmented transport and audio elementary streams). DVBViewer converts it internally to a transport stream.

    • master playlists that offer streams with different video/audio formats (e.g. H.264/HEVC). The desired format can be selected by appending ?codec=… to the URL (or &codec=… if there is already a query part). The specified codec must be a sub-string of (or equal) the CODECS attribute in the master playlist, e.g. codec=avc1

  • Added: Transcoded Streaming: Transcoding of video only files (without audio) except for HLS output. Previously FFmpeg rejected such files with an error. Please note: As soon as the Media Server uses the files config\iphoneprefs.ini (for HLS output) or config\ffmpegprefs,ini (for other output), it will replace them by new versions and rename the previous ones to *.bak. This can be avoided by changing the version number in the old files with a text editor from 5 to 6.

  • Fix: Transcoded Streaming: WebM or Flash streams with identical parameters could not be played at the same time by more than one client (see here).

Miscellaneous

  • Added: Channel List: Monitoring of the files channels.dat and favourites.xml. After changes the Media Server automatically reloads them with a delay of one to two seconds, and additionally the associated files ChannelsURL.ini and DiSEqC.xml. Thus changes in the channel or favorites list performed by the local DVBViewer or TransEdit take effect in the Media Server, as soon as the files are saved, without the need to stop and restart the server. However, web interface pages have to be reloaded manually in the browser in order to make channel list changes visible.

  • Change: Hardware Options: The tuner type of BDA devices cannot be changed anymore in the options, in order to prevent misconfiguration by users (see here). If really necessary, the type must be tweaked by editing the file svchardware.xml (0 = Cable, 1 = Satellite, 2 = Terrestrial, 3 = ATSC), while the Media Server is stopped.

  • Added: Web/UPnP Options: EPG Checkbox in the Live Stream Server section for adding EPG data to HTTP live streams (if contained in the received stream).

  • Added: Task Options: The new “Placeholders” button in the Task Editor opens a window that enumerates the placeholders that can be used in command line parameters for after recording tasks. On mouse-over the window shows hints containing examples for the replacement applied by the Media Server. Double-clicking a placeholder or pressing Enter inserts it in the parameters field of the Task Editor.

The placeholders specify where the path\filename or other recording properties shall be inserted in the command line. Additionally they allow to set up conditions that decide which parts of the command line shall be used or omitted in certain cases.

  • Added: Task Options: A new “Maximum timer duration” input field allows to specify a duration for the timer that is associated with an after recording task. Please note that the timer does not stop the task when it is due, but prevents sleep mode, hibernate or shutdown while it is active. The timer is automatically canceled when the task terminates.

  • Added: Media Server Options:Extra wake up lead time” tweak (→ launch DMSTweaker.bat). It specifies the extra lead time in minutes for the wake-up process of the PC before a recording starts. The default is 3 minutes (see here).

  • Added: Hardware: Plugin interface that allows to support new hardware (e.g. ATSC 3.0 devices) by adding a DLL.

  • Removed: Hardware: Support for Freenet DVB-T2 USB devices. If still needed the support will be added again as plugin (see above).

Changes Media Server 3.0.1 (Bugfix Release)

  • Fix: Installer: The file openssl.exe was not copied to the Media Server program directory, causing the creation of self-signed certificates in the Media Server Options to fail.
  • Fix: Installer: After running the installer a cmd.exe process persisted, because the batch file CreateHTTPSCertificates.bat (executed by the installer) did not terminate due to a Pause command.
  • Fix: Plugin Interface: A bug disabled the usage of some plugins (see here).
  • Fix: TS Stream: The Media Server displayed no EPG for TS Stream channels delivered via HTTP by receivers/servers like Dreambox or VU+.
  • Fix: Recorder: The Media Server could not delete recordings without filename (like D:\MyVideos\.ts).
  • Change: Recorder: Timers for timeshift recordings are not written to the file svctimers.xml anymore. This prevents the restart of timeshift recordings after a Media Server stop and restart. Furthermore the Media Server deletes timeshift recordings when it is stopped, provided they are not opened in a client anymore.
  • Fix: API: Wrong EPG data assignment to timers that were added via api/timeradd.html (particularly by DVBViewer and add-ons). The Media Server used the program running at the start time, not as intended the program running in the middle between start and end time.
  • Fix: Web/Live Stream Server: Instability if clients were using the Web and Live Stream Server extensively (particularly Kodi).
  • Fix: Hardware Options: The tuner type selection has been re-enabled for HDHomeRun devices. It is required because the tuner type information exposed by the driver is ambiguous (see here).

Changes Media Server 3.0.2 (Bugfix Release)

  • Change: Web Interfaces: Some corrections and additions (see here)
    • Desktop Web Interface: Lighter background color for selected elements in the channel list tree view of the Channel EPG page, so that the tuner type icons of selected channels remain visible.
    • Desktop Web Interface: Size adjustments in the Timer dialog avoid an unnecessary horizontal scrollbar (particularly in Chrome and Edge),
    • Desktop / Mobile Web Interface: Tuner type icons have been added to the status page.
    • Desktop / Mobile Web Interface: The status and signal quality columns on the Status page have been merged to a single column, because they are never used at the same time.
    • Desktop / Mobile Web Interface: The Status page of the Mobile Web Interface now refreshes itself every 10 seconds. Previously the refresh had to be done manually. The refresh time of the desktop Status page has been shortened from 15 to 10 seconds.
    • Mobile Web Interface: Wrong relative JavaScript paths disabled using the Timeline page if a reverse proxy was used.
  • Fix: Web Server: If “Configuration → Web Interface → Show timer edit window” was switched on, timer creation on an EPG page did not store the EPG title and subheading in the timer data.
  • Change: Recorder: The EPG monitoring option “Start/Stop by EPG running status" is now automatically replaced by "Start / End time update from EPG" if imported EPG data is used for the to be recorded channel (see here).
  • Fix: Recorder: If a timer recording was supplied with external (imported) EPG data, but also received the native now/next DVB EPG while the recording was going on, it replaced the Event ID of the imported data by the DVB Event ID, thus causing inconsistencies (see here).
  • Change: Recorder: Recordings that are started by manually created timers via “New Timer” on the Timers page of the Web Interface (not from an EPG page) now perform logging of now/next EPG data, if available. Previously this was disabled due to a missing Event ID (see here).
  • Fix: Recorder: Audio frames (particularly AAC frames) that were not aligned with the data packets, misled the audio format detection of the recorder repeatedly and yielded wrong entries in the recording log  (see here).
  • Fix: TS Stream: A wrong calculation of time stamps for MP3 streams (particularly internet radio) with 44.1 kHz sample rate could cause periodically interrupted playback after 20 to 30 minutes.
  • Added: Hardware: Possibility to flag devices in the hardware database with “needs tuner type selection”, so that tuner type selection is enabled for them on Options → Hardware, thus avoiding the necessity to change it in the file hardware.xml. Up to now this applies to HDHomeRun devices and the Hauppauge WinTV-dualHD ATSC Tuner (see here).
  • Fix: Timeshift: The DVB hardware used for timeshift recording was not released correctly after a “Keep Timeshift File” on/off change in DVBViewer. Besides that issues after using TV/Radio → Stop Timeshift Recording in DVBViewer were fixed.
  • Added: EPG: Experimental possibility to supply IPTV channels with an EPG if the same channel is received via DVB-S/T/C. The mechanism is based on a user-created text file EPGPairingList.txt in the configuration folder that specifies source and target EPG Channel ID pairs. DVBViewer and Media Server share the same file. They load it when they are started. It works for both in the same way. Please read the DVBViewer Pro 7.0.2 release notes for further details.

Changes Media Server 3.1.0

  • Added:  EPG Search: Hint for the “Search for” input line on the Search EPG page (Desktop Web Interface only). It appears on mouse over and enumerates characters with a special meaning that can be used for the search if “Use regular expressions” is switched off.
  • Added: EPG Search: Checkbox “Also deactivate on a match up to the end of the shorter title/subheading” in the Timer Settings panel of the Search EPG page. It refers to automatic recording timer creation by search presets. The option deactivates automatically created timers, if the EPG title/subheading equals the title/subheading of an already existing recording or timer up to the end of the shorter one. It lets the Media Server ignore additional information like “minimum age 12 years” appended to one of the titles, which otherwise would prevent recognition. However, “Red Roses” and “Red Roses in Winter” would also yield such a partial match, for example.
  • Change:  EPG Search: The Search EPG page now also supports using the pipe character “|” in search items as logical OR, if “Use regular expressions” is switched off. This enables searching two or more titles with a single search item, e.g. The Walking Dead|Grey’s Anatomy|Games of Thrones, that finds all three series. Previously this was only possible with regular expressions (see here).
  • Fix: EPG Search: Non-ASCII-letters (like German umlauts) were regarded as word boundaries by the search engine, if double quotes (or \b in regular expression mode) were used for a “whole word only” search, thus yielding unwanted results. It has been fixed by a more up-to-date search engine in a DLL (pcre.dll).
  • Added: EPG: Tweak “Remove (German) gender-neutral language” (→ launch DMSTweaker.bat). If activated, it replaces German forms of gender-neutral language in the EPG by generic forms, either masculine or feminine: 0 = unchanged (default), 1 = masculine (Musiker*innen → Musiker), 2 = feminine (Musiker*innen → Musikerinnen). Please note that the setting is applied to EPG data when it is received, not to data already stored in the file \config\epg.dat. Thus it may take time until it fully takes effect, unless the file is deleted.
  • Fix: Web Interface: Issues if the Media Server had to display a channel as selected, that was not part of the displayed channel list in the Timer Dialog or in the Stream Playback Window, particularly in case of channel list items assigned to a timer, that are not the main audio track in the channel list. The missing entry is now simply attached to the end of the displayed channel list.
  • Fix: Desktop Web Interface: Some adjustments on the EPG Search, Configuration, Timers and Status pages.
  • Fix: Desktop Web Interface: Changing the language on the Configuration Page did not work with Safari.
  • Fix: Desktop Web Interface: The Recordings page was not updated after editing a recording.
  • Fix: Transcoded Streaming: Transcoded streaming failed if the client did not specify a preset and a default preset (640x360 resolution or lower) for the requested format was not available in the file ffmpegprefs.ini or iphoneprefs.ini. Now the Media Server uses the last available preset (with the highest index) for the requested format in this case.
  • Fix: TS Stream: HLS channels were played and recorded without audio if the broadcaster used MP4 segments that contained both video and audio, instead of separate segments.
  • Change: UPnP: On video database updates the Media Server now tries to retrieve a short description of the file via MediaInfo.
  • Change: UPnP: The Media Server does not include long descriptions anymore if it delivers recordings as videos to UPnP clients, but confines the text metadata to the EPG title and subheading.
  • Added: UPnP: Possibility to transcode radio streams to the FLAC audio format. It requires FFmpeg and modifying the file \config\UPnPProfilesV4.xml in the configuration folder. For transcoding MP2 audio the profile in question must contain the following lines in the <LiveExtensions> section:

<Ext name=".mp2">

  <MediaFormat mime-type="audio/flac" alias=".flac" transcode="-1" hassize="-1" allaudio="0"></MediaFormat>

</Ext>

For other radio source formats like AC3 or AAC the Ext element must be modified accordingly (Ext name=".ac3", Ext name=".aac" etc.).

  • Added: UPnP: 6 tweaks allowing to modify the FFmpeg command lines for transcoded UPnP radio output (→ launch DMSTweaker.bat). Transcoding to MP2, MP3, AAC, AC3, WAV and FLAC is supported. It is defined for each UPnP profile separately in the file UPnPProfilesVX.xml (X = version number) within the <LiveExtensions> element. The file is located in the config sub-folder of the configuration folder.
  • Removed: UPnP: Tweaks “MP3 bit rate for UPnP transcoding” and “MP3 sample rate for UPnP transcoding”. Both parameters can now be influenced by modifying the FFmpeg command line for MP3 (see above). The bit rate is the value after the -ab command (in kbps, followed by the letter k). It must be a valid MP3 bit rate (e.g. 128k, 160k, 192k, 320k). The sample rate is the value after the -ar command (in Hz). It must be a valid MP3 sample rate (e.g. 32000, 44100, 48000).
  • Fix: Recorder: Options →  Recordings → Auto split on channel data change was not handled correctly, particularly in case of dynamic program switching by the broadcaster, as performed by the German ARD when switching to regional editions of a program and back to the main program.
  • Fix: General: If a WebGeneral → Root entry in the file service.xml (possibly created by an old Recording Service version) specifies a path to a SVCweb folder that does not exist, the Media Server now falls back to the default (usually C:\Program Files (x86)\DVBViewer\SVCweb) instead of canceling its initialization.

Changes Media Server 3.1.1

  • Added: Options: After a new (first) installation, when no configuration has taken place yet (no config\service.xml is present), the Media Server and its options (svcoptions.exe) adopt several settings from DVBViewer on the same PC, in order to spare users a manual adaptation (see here). This applies to the following DVBViewer settings:
    • Options → Extended: Don’t shut down if a recording is due within…
    • Options → Recordings: Recording/Timeshift directories, minimum free disk space, all settings except “Signal recording in the video window”.
    • Options → Recording Timers: All default timer settings except the default timer action (that is always “Record” in the Media Server).
    • Options → EPG: Preferred language and time zone settings
    • Options → Hardware: The complete device list including all settings, except RTSP network devices referring to a (previous) Media Server installation on the same PC.
    • Options → Movies/Music/Images: Media paths (except CD/DVD drives).
    • All tweaks that have the same meaning in DVBViewer and the Media Server.
  • Added: Recordings: If the recordings database is empty (particularly after a new/first Media Server installation), the Media Server copies the content of the DVBViewer recording database on the same PC to its own database, provided the recordings exist and are located in a Media Server recording directory. This procedure is only performed once. It sets a flag in the file service.xml that prevents further attempts (entry Recording → DVBViewerDBRead).
  • Change: Recordings: If a recording is deleted by or in the Media Server, directories that were automatically created for this recording due to path elements in the file naming scheme (e.g. %year\%m\%event\…) are now deleted too if they are empty after deletion of the recording. This also applies to timeshift recordings. Please note that Windows may prevent the deletion of empty directories in case of access conflicts e.g. with the Explorer.
  • Added: Recorder: Support for %season and %episode placeholders in the file naming scheme. If no season and/or episode value is available, the placeholders are removed.
  • Added: Recording / Radio Text: Recording of RDS data that is not contained in the audio data, but in a separate stream, as used by German ARD radio channels after changing the audio format from MP2 to AAC. The radio recording format must be TS and the “Include Teletext” option switched on for the timer in question. DVBViewer is able to display the radio text when playing such a recording.
  • Added: Recording: Tweak “Convert LOAS/LATM to ADTS for AAC recordings” (→ launch DMSTweaker.bat). For recordings with the file extension .aac it may be useful to let the Media Server convert a broadcasted LOAS/LATM container to the older ADTS container for compatibility with certain software/devices, particularly editing software like mp3DirectCut.
  • Fix/Change: Recording: Some fixes and enhancements concerning the processing of AAC audio.
  • Fix: Desktop Web Interface: Full screen video was not displayed correctly in Safari under macOS. Parts of the picture were cut off.
  • Fix: Web Server: Chrome and Edge under macOS were wrongly detected as Safari, which restricted the stream format selection for playback in the browser to HLS, though both browsers can’t play it natively.
  • Fix: Desktop Web Interface: A channel logo was only shown after a channel change in the browser window, not before the first TV/radio channel started playing.
  • Added: Desktop Web Interface: Optional teletext display when playing (transcoded) live TV in the browser. It can be switched on/off by clicking the new TXT button, provided teletext is available for the channel. Initially the teletext panel shows the first available page (usually 100). It provides the following navigation possibilities:
    • Switch to the previous/next (sub)page by clicking the <<  >> links in the top line of the page or by pressing the left/right arrow key.
    • Click a page number on a page for switching to the new page.
    • Select a page by typing the number on the keyboard. Typing 234 first selects page 200, then 230, then 234. So it is sufficient to press 2 for selecting page 200. A number can be continued / completed within two seconds after the last input. When the time has elapsed or the number is already complete, the number key buffer gets erased, so that the next input starts a new page number.
    • Update the page by clicking the page number in the top line or by typing its number again. Pages don’t update automatically in the browser.
    • Press Backspace for going back in page history and Shift + Backspace for going forward.
    • Pressing Esc hides the teletext panel.

Please note that the teletext panel can only receive keyboard input if it has the input focus. Initially (when appearing) it gets the focus. However, after clicking something else in the video window, it is necessary to first click the teletext panel somewhere in order to give it the focus again.

  • Fix: Desktop Web Interface: Editing the recording database entry of a removed recording on the Recordings → Removed page and saving the changes could create a new EPG Info File.
  • Removed: Desktop Web Interface: Support for playing Flash videos in the browser.
  • Fix: Mobile Web Interface: The last audio volume setting was read from local storage, but never saved.
  • Added: Channel Logos: Support for a new logo administration that spares providing the same logo several times with different filenames for different channel names (e.g. BBC One Scot, BBC One Lon...). In future only one logo file will be needed in this case, plus a file LogoNames.ini that assigns channel names to logo files.
  • Change: Channel Logos: Enhanced assignment of logos to channel names. It may find more or better matches by unifying the strings before comparison, particularly by replacing “+” by “plus” and removing all characters that are no letters or digits.
  • Added: UPnP/Videos: On video database updates the Media Server now queries MediaInfo.dll for additional metadata that may be contained in video files (that are no recordings) and stores the data in the database, particularly title, description, comment, genre and series title, if available (previously only the title, see here). Please note that for refreshing entries that are already present in the video database the task “Rebuild Video Database” must be performed. Checking Media Server Options (svcoptions.exe) → Tasks → Shown internal tasks → Rebuild Video Database makes this task visible in the web interface.
  • Change: EPG: Up to now the Media Server appended extensive technical information originating from EPG data to the long EPG description (e.g. aspect ratio, video format, available audio tracks, subtitles etc.), often occupying several text lines. It has now been reduced to the most important facts that may change per program. They only occupy a single line and use the following symbols/abbreviations for what is signaled in the EPG:
    • [4:3] [16:9] Program aspect ratio
    • [3D] 3D transmission
    • [HDR] High Dynamic Range video
    • [OA] Original audio provided
    • [5.1] Multi-channel (surround) audio provided
    • [SUB] Subtitles provided
    • [AD] Audio description for the visually impaired provided
    • [age+] Recommended minimum age, e.g. [16+]
    • [PDC day.month hour:minute] Originally intended program start time. The Program Delivery Control is used by the Media Server for program recognition and EPG monitoring.

Please note that this information is not always reliable. Unfortunately some broadcasters handle this EPG based information quite carelessly, e.g. signal a wrong aspect ratio or indicate subtitles for all programs if they are only available for some programs. The new format is applied to newly received EPG entries, not to already stored entries.

  • Change: EPG/Teletext: Further enhancements for the “Remove (German) gender-neutral language” function (see 3.1.0 changes).
  • Fix: TS Stream: Erroneous confusion of the HTTP Location header (used for redirections to another URL) with other headers that also contain the sub-string “location:”.
  • Added: Hardware: Support for assigning up to 4 CI modules in the settings dialog of RTSP network devices for Digital Devices Sat>IP servers (previously only 2).
  • Added: Hardware: On hardware detection the Media Server creates an additional DVB-C tuner entry for the TBS 5881 hybrid USB Box. This measure saves tweaking the tuner type for DVB-C reception.
  • Fix: Hardware: If the DVB-T2 substream (PLP) ID is undefined, the Media Server does not set it to 0 anymore as default for TBS devices, which prevented auto-detection in the driver and DVB-T2 reception in Austria, where the substream ID is 1 throughout. Now the TBS API call is omitted in this case (see here).

Changes Media Server 3.1.2 (Bugfix Release)

  • Added: TS Stream: Work-around for erroneous time stamp headers in HLS segments of additional audio tracks provided by German ARD channels, that caused audio drop-outs.
  • Fix: TS Stream: Teletext data in HLS segments of AAC audio delivered as separate stream was mistaken for audio.
  • Fix: Recorder: Under certain timing conditions the recorder detected the wrong AAC type when a channel with LOAS/LATM AAC audio was recorded, causing permanently changing wrong format information in the recording log, but without disturbing TS recordings.
  • Fix: Desktop Web Interface/Teletext: Navigation issues if a displayed teletext page contained an internet address. Its <a href...> tag wasn’t closed correctly.
  • Fix: Web Server: Delivery of (untranscoded) live streams failed if the URL contained the sub-string “/teletext” for letting the server include teletext (since version 3.1.1). This particularly affected DVBViewer clients on the same PC that delegated TS Stream reception to the Media Server.
