int(* AVOutputFormat::write_packet) (struct AVFormatContext *, AVPacket *pkt) |
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.

int(* AVOutputFormat::interleave_packet) (struct AVFormatContext *, AVPacket *out, AVPacket *in, int flush) |
A format-specific function for interleavement.
If unset, packets will be interleaved by dts.

int(* AVOutputFormat::control_message) (struct AVFormatContext *s, int type, void *data, size_t data_size) |

int(* AVOutputFormat::write_uncoded_frame) (struct AVFormatContext *, int stream_index, 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.

Free device capabilities submodule.
Definition at line 600 of file avformat.h.
enum AVCodecID AVOutputFormat::data_codec |
int(* AVOutputFormat::init) (struct 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().
Definition at line 611 of file avformat.h.
void(* AVOutputFormat::deinit) (struct 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.
Definition at line 620 of file avformat.h.
int(* AVOutputFormat::check_bitstream) (struct AVFormatContext *, const AVPacket *pkt) |
Set up any necessary bitstream filtering and extract any extra data needed for the global header.
Return 0 if more packets from this stream must be checked; 1 if not.
