Hi All,

The problem described in the ticket #3261 is connected to approach used 
by VSSH codec to put B-frames into AVI format.

VSSH format with B-frames is as following:
Meta data contains [startcode][SPS][startcode][PPS]
Frame #0: [startcode][SPS][startcode][PPS][startcode][I-picture]
Frame #1: [startcode][P-picture][startcode][B-picture]
Frame #2: [startcode]
Decoder is supposed to output B-frame on step 
#1<https://trac.ffmpeg.org/ticket/1> and P-frame on step #2.

Do you think this issue should be fixed?
Where is in the code the place where H264 decoder does expect that every 
AVI frame contains one and only one video frame?

Best Regards,
