[FFmpeg-devel] [ffmpeg-devel] issue with decoding h.264 video from tandberg encoder

Interestingly, I had no problems with the decoding for quite a lot of 
H.264 video (as in no artifacts or jitter in the displayed video) even 
when the message

[h264 @ 0x844a910]Interlaced pictures + spatial direct mode is not implemented

was reported. But with the H.264 video from the Tandberg encoder, the 
decoded video was crappy. So I am wondering what's the difference 
between those interlaced video. Did you see the artifacts and jitter in 
the video when you play them back?

Sorry for my reposting. I would want to be more patient, but the 
deadline for my project delivery is around the corner. If this cannot be 
resolved in libavcodec in the short term, I would need to turn to 
something else. I don't mind paying money as long I can get those H.264 
video from the Tandberg encoder decoded properly in order to save my ass :-)
