Hi, I have AVCHD files from a camera (Panasonic Lumix GH1) that demux and decode with libavformat/libavcodec detecting no other keyframe but the first (both, the first video packet and video frame are marked as keyframe), which is not what I would have expected for those clips as the GOP structure of files produced by this camera is known to be different.
My question is now, what libavcodec/libavformat uses as criteria to decide whether a packet is a keyframe packet or a frame is a keyframe in this case. Does it only trigger in the case of IDRs or are recovery point SEIs also detected? Should I open a trac issue for this with a sample? My requirement is, I want to find points in the stream suitable for random access using libavformat/libavcodec. What are my options for this kind of files?
