Description

I just noticed that there is some flickering at the start of the replay of all PES recordings (mpeg2), TS recordings (mpeg and H.264) are fine. It looks like a problem with the I-frame of the first GOP as the flickering diasappears after about half a second.

BTW: there's no flickering with the same recordings on S2-6400 so I assume the VDR part is ok

I have here a pes recording.
Which shows the same effect.
But I don't know how to fix it.

mplayer didn't show the blocks,
but i think nothing is missing.

I think the problem is that pes recording feeds the ffmpeg/libav decoder with incomplete/truncated packets.
Enabling STILL_DEBUG and InStillPicture shows the problem.
