Please don't top-post. I have to admit the new BSF API is super-confusing. I think you return EAGAIN but you also have to deallocate the "out" AVPacket. See http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavcodec/vp9_superframe_bsf.c;h=b686adbe1673f564d252a30cff11c5895a9a3b55;hb=HEAD as an example. The EAGAIN is handled here: http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavcodec/bitstream_filter.c;h=02878e3bf3e9771f5921ce218771f041e19f2d59;hb=HEAD#l144 and the unref will zero the packet, which invokes this code: http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavformat/utils.c;h=07113107920a910d3b3094f01a1b3f8a58b11072;hb=HEAD#l5256 and then it will skip the packet and wait for the next. I'm not sure how to retrieve delayed packets though, it seems that's simply not possible ATM, not in FFmpeg but also not in Libav - at least using the av_bitstream_filter_filter() function... (?)
