antdude Posted October 11, 2011 Share Posted October 11, 2011 (edited) Hello. I am using DVBViewer Pro v4.9.0.0 in an old, updated Windows XP Pro. SP3 machine. I noticed when playing my recording MPEG-2 videos in progress in it, I do not have subtitles and 5.1 audio setup (DVBViewer says AC3 2.0 the whole time). If I stop recording and play that same video file back, then I can get subtitles (shows none) and proper audio setups. Manually using timeshift is fine though, but I am not always there do the manual timeshift when my video starts since I use the timer/scheduler. FYI if it helps with a MPEG-2 recording and playing it back live I am doing right now: 10-10_19-55-00_KTTV DT (eng) 11.1_Terra Nova.log: KTTV DT (eng) 11.1 10/10/2011 G:\videos\recorded\10-10_19-55-00_KTTV DT (eng) 11.1_Terra Nova.mpg Device: Air2PC-ATSC-PCI 1 7:55:00 PM / 12:00:00 AM (~ 0.0 MB) Start 7:55:01 PM / 12:00:01 AM (~ 1.7 MB) PID 49: MPEG2 Video, 16:9, 1280x720, 59.94 fps 7:55:01 PM / 12:00:01 AM (~ 1.7 MB) PID 52: AC3 Audio Stereo, 48 khz, 448 kbps 7:55:01 PM / 12:00:01 AM (~ 1.7 MB) PID 53: AC3 Audio Stereo, 48 khz, 384 kbps 7:59:29 PM / 12:04:29 AM (~ 492.9 MB) PID 52: AC3 Audio 5.1, 48 khz, 448 kbps 8:21:36 PM / 12:26:36 AM (~ 2858.3 MB) PID 52: AC3 Audio Stereo, 48 khz, 448 kbps 8:23:11 PM / 12:28:10 AM (~ 3017.0 MB) PID 52: AC3 Audio 5.1, 48 khz, 448 kbps 8:40:28 PM / 12:45:27 AM (~ 4925.0 MB) PID 52: AC3 Audio Stereo, 48 khz, 448 kbps 8:42:39 PM / 12:47:39 AM (~ 5176.8 MB) PID 52: AC3 Audio 5.1, 48 khz, 448 kbps 10-10_19-55-00_KTTV DT (eng) 11.1_Terra Nova.txt: [General] Version=1.1 [Media] Created=10.10.2011 19:55:00 Channel=KTTV DT (eng) 11.1 LastShown=30.12.1899 LastPosition=0 Played=0 [0] Id=5065 Date=10.10.2011 Time=20:00:00 Duration=01:00:00 Title=Terra Nova Info= Description=Elisabeth, Jim, Malcolm and Taylor discover a mysterious virus that causes memory loss, paranoia, and eventually death when they investigate radio silence at a nearby scientific outpost, so they must work together to find a cure before it's too late.

Griga Posted October 11, 2011 Share Posted October 11, 2011 I do not have subtitles Terra Nova.mpg Have you already tried recording as TS? DVBViewer says AC3 2.0 the whole time What does the DVBViewer Filter property page say? Quote Link to comment
antdude Posted October 11, 2011 Author Share Posted October 11, 2011 (edited) Have you already tried recording as TS? What does the DVBViewer Filter property page say? No, I have not tried TS format. After messing with it, I think I figured out what's wrong. It seems like I had to pick the other audio track ("AC3 Audio Stereo (2)" instead of "AC3 Audio Stereo (1)". Weird. I wonder why 5.1 wasn't on the first one. I have not fixed the closed captions/subtitles part yet. CCExtractor GUI v0.59 does see them and I was able to extract. I attached a screen shot of DVB Source properties when using default audio track #1. Edited October 11, 2011 by antdude Quote Link to comment
SimonP Posted October 11, 2011 Share Posted October 11, 2011 (edited) As Griga said, change to recording in .ts format. My understanding is that .mpg doesn't record subtitles and it only saves one audio stream whereas .ts saves everything that is transmitted so I'm surprised that you were able to get subtitles from a .mpg recording. Check out MediaInfo, it's a very useful tool for finding out what is contained in recordings. Edited October 11, 2011 by SimonP Quote Link to comment

Griga Posted October 11, 2011 Share Posted October 11, 2011 My understanding is that .mpg doesn't record subtitles ATSC closed captions are part of the video data (in the MPEG2 user_data section), so they are recorded for sure in MPG files. However, as European software DVBViewer doesn't seem to take this into account, because DVB subtitles are located in a separate stream that can only be recorded as TS. @antdude: What are your settings for MPG playback? Is the DVBViewer Filter enabled for MPG playback in the DirectX options? If not, what is listed under View -> Filters when a MPG file (not being in progress) is played? AFAIK DVBViewer doesn't contain native support for ATSC closed captions in MPG files (only for TS), so I guess some third party DirectShow filter is looking after it. However, when it comes to playing ongoing recordings, DVBViewer forces DVBViewer Filter usage, because many other source resp. splitter filters are not able to open files in shared mode (one instance writing, another one reading). That would explain the missing subtitles in ongoing recordings. Quote Link to comment

Griga Posted October 11, 2011 Share Posted October 11, 2011 If I stop recording and play that same video file back, then I can get subtitles I really wonder how you made it I've tried the following: - Played a ATSC sample TS file with DVBViewer. Closed captions were displayed. - Used TSPlayer to convert the file to MPG (TSPlayer uses the DVBViewer recording engine for re-recording a TS file in a different format) - Played the MPG file in DVBViewer. Settings -> Subtitles just says "None". No subtitles whatsoever. Quote Link to comment
antdude Posted October 11, 2011 Author Share Posted October 11, 2011 I really wonder how you made it I've tried the following: ... What do you mean made it? It's directly from DVBViewer's timer recording and then I manually played that same video file with drag and drop from recording folder. oh well, I can live without the subtitles/CCs. At least I have my audio tracks working now if I switch it manually (still should be detecting the right one with 5.1?). Quote Link to comment
Griga Posted October 11, 2011 Share Posted October 11, 2011 What do you mean made it? Well, it's simply impossible. DVBViewer (at least with the DVBViewer Filter as source filter) doesn't display ATSC closed captions in MPG files. It doesn't here. I know the DVBViewer CC decoder code. It's only designed for processing TS packets. Some supernatural power must be involved... Quote Link to comment

Derrick Posted October 11, 2011 Share Posted October 11, 2011 ..either he can't see the CC subs or he uses another player/splitter.. DVBViewer forces DVBViewer Filter usage, because many other source resp. splitter filters are not able to open files in shared mode but: If I stop recording and play that same video file back, then I can get subtitles He doesn't say that dvbv is used for playback Quote Link to comment
Griga Posted October 11, 2011 Share Posted October 11, 2011 (edited) He doesn't say that dvbv is used for playback He does: Yes, DVBViewer Filter is enabled for .MPG and .TS. P.S. Well, ok, not explicitely. Maybe he's using VLC for MPG playback and doesn't dare to admit it here. Edited October 11, 2011 by Griga Quote Link to comment
antdude Posted October 11, 2011 Author Share Posted October 11, 2011 ..either he can't see the CC subs or he uses another player/splitter.. but: He doesn't say that dvbv is used for playback I did use DVBV for playback on recordings (in progress and finished). Quote Link to comment
Griga Posted October 11, 2011 Share Posted October 11, 2011 I did use DVBV for playback on recordings (in progress and finished). Last hope gone... anyway, the VLC media player is able to play DVBViewer MPG recordings in progress and to display ATSC closed captions in MPG files (just tried). That would be a solution for your problem (not for mine ). Quote Link to comment

That would be a solution for your problem (not for mine ). Ah I will try that later (not at the PC to try it). I'd love to use DVBViewer's player instead especially with in progress recording. If I use VLC or another player, then I will have two players going and I don't think my fullscreen to my 1996's 20" CRT TV will work due to conflicts. Quote Link to comment
Griga Posted October 11, 2011 Share Posted October 11, 2011 You can switch playback off in DVBViewer (View -> Close Graph) without affecting the recording. Quote Link to comment
antdude Posted October 11, 2011 Author Share Posted October 11, 2011 You can switch playback off in DVBViewer (View -> Close Graph) without affecting the recording. Ah, I wasn't aware of that trick. I assume I can reopen that graph too? Quote Link to comment
Griga Posted October 12, 2011 Share Posted October 12, 2011 I assume I can reopen that graph too? Sure. Use Channel -> Last Channel. Another thing: I'm curently working on ATSC CC improvements, but I have only two sample files - quite poor for testing. Could you upload additional TS samples containing CCs to some hoster? 30 seconds or so per file would be sufficient. TS is better because it can easily be converted to MPG, but not the other way round. My samples only contain roll-up style captions (as used for live shows), so additional samples with pop-on style captions (as used for movie subtitling) would be good. Or even better a sample that switches between the styles, but that might be hard to catch Quote Link to comment

I have a 5 seconds TS file (saw its subtitles after recording and watching it in DVBV) that is already 9 MB from a live local news (same station as Terra Nova from last night that I mentioned)!

Griga Posted October 12, 2011 Share Posted October 12, 2011 Um, where do I upload it? There are free hosters like RapidShare and MegaUpload, but I'll ask Christian and Lars if there is a better solution... I can't upload very big files since my upload speed sucks I know that. Usually it becomes a background task for times when my PC has nothing else to do. What is your upload data rate? Quote Link to comment

I know that. Usually it becomes a background task for times when my PC has nothing else to do. What is your upload data rate? 384 Kb. Also, it is shared with other people. Anyways, I uploaded the 9 MB zipped TS file to here: http://www.multiupload.com/BQU5SG2F5S ... I hope it works. I am going to sleep now. Quote Link to comment
Griga Posted October 12, 2011 Share Posted October 12, 2011 384 Kb. Same here Anyways, I uploaded the 9 MB zipped TS file Thanks It's HDTV, that's why it gets so big. Are there still SD channels broadcasting in your region? I am going to sleep now. Have a good (rest of the) night - see you later... Quote Link to comment
