Sorry for the long delay, I got sidetracked with other work.
> On a related note, one feature that only the VP8 depacketizer supports now is signalling via RTCP that it needs a keyframe (in the event of loss or the start of a stream), to do this you just have to implement the .need_keyframe callback (see https://git.ffmpeg.org/gitweb/ffmpeg.git/blob/eb79c316c7b205f45e7003e91f77c253818e6685:/libavformat/rtpdec_vp8.c#l274)
Added code to support this and enabled the extra scan for the sequence
header OBU.
