Data Fields
const char *	name

const char *	long_name
	Descriptive name for the format, meant to be more human-readable than name.

const char *	mime_type

const char *	extensions
	comma-separated filename extensions

enum AVCodecID	audio_codec
	default audio codec

enum AVCodecID	video_codec
	default video codec

enum AVCodecID	subtitle_codec
	default subtitle codec

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

struct AVCodecTag const	codec_tag
	List of supported codec_id-codec_tag pairs, ordered by "better choice first".

const AVClass *	priv_class
	AVClass for the private context.

struct AVOutputFormat *	next

int	priv_data_size
	size of private data so that it can be allocated in the wrapper

int(*	write_header )(struct AVFormatContext *)

int(*	write_packet )(struct AVFormatContext , AVPacket pkt)
	Write a packet.

int(*	write_trailer )(struct AVFormatContext *)

int(*	interleave_packet )(struct AVFormatContext , AVPacket out, AVPacket *in, int flush)
	Currently only used to set pixel format if not YUV420P.

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

void(*	get_output_timestamp )(struct AVFormatContext s, int stream, int64_t dts, int64_t *wall)

int(*	control_message )(struct AVFormatContext s, int type, void data, size_t data_size)
	Allows sending messages from application to device.

int(*	write_uncoded_frame )(struct AVFormatContext , int stream_index, AVFrame *frame, unsigned flags)
	Write an uncoded AVFrame.

int(*	get_device_list )(struct AVFormatContext s, struct AVDeviceInfoList device_list)
	Returns device list with it properties.

struct AVCodecTag* const* AVOutputFormat::codec_tag

const AVClass* AVOutputFormat::priv_class

int AVOutputFormat::priv_data_size

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::query_codec)(enum AVCodecID id, int std_compliance)

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
