int(* AVOutputFormat::query_codec)(enum AVCodecID id, int std_compliance)

Test if the given codec can be stored in this container.

Returns:
1 if the codec is supported, 0 if it is not. A negative number if unknown. MKTAG('A', 'P', 'I', 'C') if the codec is only supported as AV_DISPOSITION_ATTACHED_PIC

Write a packet.

If AVFMT_ALLOW_FLUSH is set in flags, pkt can be NULL in order to flush data buffered in the muxer. When flushing, return 0 if there still is more data to flush, or 1 if everything was flushed and there is no more buffered data.
