Write a packet.

If FF_OFMT_FLAG_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.

A format-specific function for interleavement.

If unset, packets will be interleaved by dts.

Parameters

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.

Returns

1 if a packet was output, 0 if no packet could be output, < 0 if an error occurred

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 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.

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().

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.

Set up any necessary bitstream filtering and extract any extra data needed for the global header.

Note

pkt might have been directly forwarded by a meta-muxer; therefore pkt->stream_index as well as the pkt's timebase might be invalid. Return 0 if more packets from this stream must be checked; 1 if not.
