Comment:
It's not a bug in the decoder, but in the FFmpeg cli tool: In
packet_decode() in ffmpeg_dec.c an AVPacket is sent to the decoder; if
avcodec_send_packet() does not return an error, the AVFrames are received
until the decoder signals EAGAIN. But if an error happens, no call to
avcodec_receive_frame() happens and the decoder is supposed to need new
input to produce any output. This is wrong for VP9 (and maybe some other
decoders) as there is a BSF involved and the BSF need not have been
completely drained.
