In Poland we have two transportstreams:
- first contains three services encoded with MPEG2 and three with H264 - all are working OK
- second contains only three H264 services - they aren't displayed at all starting from SVN build 16629. In previous build 16622 they are working.

I checked logs from 16629 build and they are:

I've checked also newest build 16867 but the problem still exists.

Thx

I had a little bit time to debug this problem. I found that there is problem with PMT decoding.
During PMT decoding pidInfo.stream_type is set to 27 (AVC stream) properly. But in this transportstream there is also sent video descriptor for this stream and DecodePMT method resets pidInfo.stream_type to 2 - but WHY!!!

Is there any reason to do this. Video descriptor doesn't contain information about stream type!!!
