Is this patch still necessary after the round of fixes to FFmpeg?

My original patch did three things: 1) Write picturesize into sh_video 2) Copy extradata 3) Force frame rate detection 1) & 3) are still necessary, the teststream also works without 2), but I think it might be a good idea. If you prefer not to copy the extradata, please tell me so I can send a new patch. Carl Eugen

Why is 1) needed? This sounds like a bug elsewhere to me.

I can only see in the output that without 1) the line "[V]" shows size: 0x0 and the decoder fails. H264 can be decoded if size=0x0.
