| int(* FFOutputFormat::write_packet) (AVFormatContext *, AVPacket *pkt) |
Write a packet.
If FF_FMT_ALLOW_FLUSH is set in flags_internal, 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.

| int(* FFOutputFormat::interleave_packet) (AVFormatContext *s, AVPacket *pkt, int flush, int has_packet) |
A format-specific function for interleavement.
If unset, packets will be interleaved by dts.
| s | An AVFormatContext for output. pkt will be added to resp. taken from its packet buffer. | |
| [in,out] | pkt | A packet to be interleaved if has_packet is set; also used to return packets. If no packet is returned (e.g. on error), pkt is blank on return. |
| flush | 1 if no further packets are available as input and all remaining packets should be output. | |
| has_packet | If set, pkt contains a packet to be interleaved on input; otherwise pkt is blank on input. |

| int(* FFOutputFormat::write_uncoded_frame) (AVFormatContext *, int stream_index, struct AVFrame **frame, unsigned flags) |
Write an uncoded AVFrame.
See av_write_uncoded_frame() for details.
The library will free *frame afterwards, but the muxer can prevent it by setting the pointer to NULL.

| int(* FFOutputFormat::init) (AVFormatContext *) |
Initialize format.
May allocate data here, and set any AVFormatContext or AVStream parameters that need to be set before packets are sent. This method must not write output.
Return 0 if streams were fully configured, 1 if not, negative AVERROR on failure
Any allocations made here must be freed in deinit().

Referenced by avformat_init_output(), and init_muxer().
| void(* FFOutputFormat::deinit) (AVFormatContext *) |
Deinitialize format.
If present, this is called whenever the muxer is being destroyed, regardless of whether or not the header has been written.
If a trailer is being written, this is called after write_trailer().
This is called if init() fails as well.
