amiga666 Posted July 17, 2014 Share Posted July 17, 2014 Is any way to improve channel switching using xbmc and DVBViewer add-on? When I change the channels I have 6-5 sec break. Link to comment
VinoRosso Posted July 17, 2014 Share Posted July 17, 2014 wrong forum this is an XBMC issue.... Link to comment
amiga666 Posted July 17, 2014 Author Share Posted July 17, 2014 Is it not recording service issue? Link to comment
VinoRosso Posted July 17, 2014 Share Posted July 17, 2014 Recording service is fast with DVBViewer, so no this is an XBMC issue Link to comment
amiga666 Posted July 17, 2014 Author Share Posted July 17, 2014 OK, sorry. Maybe there is the person who can help in this issue. Link to comment
mague Posted July 17, 2014 Share Posted July 17, 2014 The problem lies within the code of XBMC. There is no workaround. Link to comment
CiNcH Posted July 17, 2014 Share Posted July 17, 2014 It heavily depends on the DVB card in use. XBMC performs a TEARDOWN and SETUP at every channel change which results in the tuner being reopened at the RS. So depending on how fast the driver of the DVB card does that will channel switching be slower or faster. With TechnoTrend for example, the CAM is reset on a tuner re-open. Switching channels with a CAM inserted therefore takes more than 10s. With Digital Devices hardware, I am at approx. 3s. Best would be, if XBMC did not perform TEARDOWN and SETUP on channel change, see here. Link to comment
test Posted July 18, 2014 Share Posted July 18, 2014 I have good results with the Margro builds: http://www.scintilla.utwente.nl/~marcelg/xbmc/prebuild.html#gotham Link to comment
CiNcH Posted July 18, 2014 Share Posted July 18, 2014 It is not bad, but SETUP/TEARDOWN is also done for each channel change. I end up with 3s with Digital Devices hardware using uPnP. Link to comment
dbraner Posted July 18, 2014 Share Posted July 18, 2014 As long as the XBMC devteam does not change this behavior XBMC is not suitable for LiveTV. XBMC is designed to playback video files. And unfortunately the developers don't watch live Tv ;-) Link to comment
Ivi Posted July 19, 2014 Share Posted July 19, 2014 Well, i am using tvheadend with xbmc and the channel switching is instant even on my Android box (ATV1200), so the tvheadend plugin has no problems with LiveTV,Teardown or whatever. I am talking about Live-TV. I mostly watch HD channels (1080i and 720p - Sky, ORF). Link to comment
CiNcH Posted July 19, 2014 Share Posted July 19, 2014 tvheadend might ignore those SETUP/TEARDOWN messages. Link to comment
Griga Posted July 19, 2014 Share Posted July 19, 2014 It is not bad, but SETUP/TEARDOWN is also done for each channel change. SETUP/TEARDOWN avoids subtle DVB / live playback related problems that may be caused by on the fly channel changes (when using the PLAY command), e.g. buffers still delivering data of the previous channel after the channel/transponder change and such. Over the years we have learned by experience to consider / handle such issues in DVBViewer, but it requires a dedication to this subject that the XBMC developers may not be able (or may not want) to invest.

bpos Posted August 13, 2014 Share Posted August 13, 2014 tvheadend might ignore those SETUP/TEARDOWN messages. Isn't it possible to make the Recording Service ignore those messages also (question to devs)? Link to comment
