const char* AVOutputFormat::long_name |
Descriptive name for the format, meant to be more human-readable than name.
You should use the NULL_IF_CONFIG_SMALL() macro to define it.

const struct AVCodecTag* const* AVOutputFormat::codec_tag |
List of supported codec_id-codec_tag pairs, ordered by "better choice first".
The arrays are all terminated by AV_CODEC_ID_NONE.

int(* AVOutputFormat::write_header) (struct AVFormatContext *) |
Definition at line 566 of file avformat.h.
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.

Definition at line 575 of file avformat.h.
int(* AVOutputFormat::interleave_packet) (struct AVFormatContext *, AVPacket *out, AVPacket *in, int flush) |

int(* AVOutputFormat::query_codec) (enum AVCodecID id, int std_compliance) |
Test if the given codec can be stored in this container.

int(* AVOutputFormat::control_message) (struct AVFormatContext *s, int type, void *data, size_t data_size) |
Allows sending messages from application to device.
Definition at line 595 of file avformat.h.
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.
Definition at line 606 of file avformat.h.
int(* AVOutputFormat::get_device_list) (struct AVFormatContext *s, struct AVDeviceInfoList *device_list) |
Returns device list with it properties.

int(* AVOutputFormat::free_device_capabilities) (struct AVFormatContext *s, struct AVDeviceCapabilitiesQuery *caps) |
Free device capabilities submodule.
Definition at line 622 of file avformat.h.
enum AVCodecID AVOutputFormat::data_codec |
default data codec
Definition at line 623 of file avformat.h.
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.
Any allocations made here must be freed in deinit().
Definition at line 631 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 640 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.
