[MPlayer-users] Problems with h.264 and lavf demuxer (paff/mbaff?)

Wed Mar 5 15:50:25 CET 2014

Hi,
c
I have problems playing recorded DVB streams containing h.264 video.
The video is flagged as interlaced; however it only consists of progressive material,
s I guess they used PAFF or MBAFF on encoding. When playing the video using mplayers
default demuxer, all is fine. But if I use the lavf demuxer, the first GOPs are totally
broken until the next IDR frame arrives. ffmpeg shows the same behavior on transcoding
as the mplayer lavf demuxer; ffplay completely skips the broken part and starts decoding
at the second IDR frame. It does not make any difference if I demux the TS into
elementary streams and then play the 264 file directly - same problems. The lavf output
shows some "PES packet size mismatch" notes, but I'm not sure if this is relevant as
the pure elementary stream also does not play.

I saw the note of uploading a testsample. Is it still relevant also the problem seems
to be in the demuxer, not the decoder?

Best regards, Marco

Here is the output of mplayer with default demuxer:
