AVOutputFormat

audio_codec AVCodecID audio_codec;: < default audio codec
check_bitstream int function(AVFormatContext*, const AVPacket* pkt) check_bitstream;: 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.
codec_tag
AVCodecTag** 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.
control_message int function(AVFormatContext* s, int type, void* data, size_t data_size) control_message;: Allows sending messages from application to device.
create_device_capabilities int function(AVFormatContext* s, AVDeviceCapabilitiesQuery* caps) create_device_capabilities;: Initialize device capabilities submodule. @see avdevice_capabilities_create() for more details.
data_codec AVCodecID data_codec;: < default data codec
deinit void function(AVFormatContext*) deinit;: Deinitialize format. If present, this is called whenever the muxer is being destroyed, regardless of whether or not the header has been written.
extensions char* extensions;: < comma-separated filename extensions
flags int flags;: can use flags: AVFMT_NOFILE, AVFMT_NEEDNUMBER, AVFMT_RAWPICTURE, AVFMT_GLOBALHEADER, AVFMT_NOTIMESTAMPS, AVFMT_VARIABLE_FPS, AVFMT_NODIMENSIONS, AVFMT_NOSTREAMS, AVFMT_ALLOW_FLUSH, AVFMT_TS_NONSTRICT
free_device_capabilities int function(AVFormatContext* s, AVDeviceCapabilitiesQuery* caps) free_device_capabilities;: Free device capabilities submodule. @see avdevice_capabilities_free() for more details.
get_device_list int function(AVFormatContext* s, AVDeviceInfoList* device_list) get_device_list;: Returns device list with it properties. @see avdevice_list_devices() for more details.
get_output_timestamp void function(AVFormatContext* s, int stream, int64_t* dts, int64_t* wall) get_output_timestamp;: Undocumented in source.
init int function(AVFormatContext*) init;: 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.
interleave_packet int function(AVFormatContext*, AVPacket* out_pkt, AVPacket* in_pkt, int flush) interleave_packet;: Currently only used to set pixel format if not YUV420P.
long_name char* 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.
mime_type char* mime_type;: Undocumented in source.
name char* name;: Undocumented in source.
next AVOutputFormat* next;: No fields below this line are part of the public API. They may not be used outside of libavformat and can be changed and removed at will. New public fields should be added right above. ****************************************************************
priv_class AVClass* priv_class;: < AVClass for the private context
priv_data_size int priv_data_size;: size of private data so that it can be allocated in the wrapper
query_codec int function(AVCodecID id, int std_compliance) query_codec;: Test if the given codec can be stored in this container.
subtitle_codec AVCodecID subtitle_codec;: < default subtitle codec
video_codec AVCodecID video_codec;: < default video codec
write_header int function(AVFormatContext*) write_header;: Undocumented in source.
write_packet int function(AVFormatContext*, AVPacket* pkt) write_packet;: 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.
write_trailer int function(AVFormatContext*) write_trailer;: Undocumented in source.
write_uncoded_frame
int function(AVFormatContext*, int stream_index, AVFrame** frame, uint flags) write_uncoded_frame;: Write an uncoded AVFrame.
