I am using vdr and a TT S2 6400 card, along with the latest versions of vdr, all related drivers, firmware and plugin, very sucessfully for some time now, except for one channel, which will not decode the video - audio is fine.


I have spent some time with dvbsnoop and DVBInspector, trying to find out what is wrong, but am now out of ideas and wondered if you could offer some suggestions.

If I get vdr to record this channel, nothing is recorded and likewise if I try to stream the channel to MPlayer on another machine using streamdev-server, I get nothing and this is the output:

Cache size set to 2048 KBytes
Cache fill: 15.41% (323172 bytes)

libavformat version 55.8.102 (internal)
TS file format detected.
Cache empty, consider increasing -cache and/or -cache-min. [performance issue]
VIDEO MPEG2(pid=308) AUDIO MPA(pid=256) NO SUBS (yet)!  PROGRAM N. 0
Cache empty, consider increasing -cache and/or -cache-min. [performance issue] Cache empty, consider increasing -cache and/or -cache-min. [performance issue] Cache empty, consider increasing -cache and/or -cache-min. [performance issue]


If however, if I use dvbsnoop to dump the raw ts to a file:

dvbsnoop -b -n 10000 -s ts -tsraw > ch9raw.ts

I can play this in Mplayer fine - audio and video are perfect:

Note the first Mplayer example thinks the video PID (308) is MPEG2 and the second is H264.

DVBInspector confirms the video stream is H264.

What is it that I should be looking for wrong in the stream, that vdr will not record this channel or pass the video stream through the system?


Thank you for anything you can offer.

Kind regards,

Richard Scobie
