FFmpeg: AVCodec Struct Reference

#include <avcodec.h>

Data Fields
const char *	name
	Name of the codec implementation.

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

enum AVMediaType	type

enum AVCodecID	id

int	capabilities
	Codec capabilities.

const AVRational *	supported_framerates
	array of supported framerates, or NULL if any, array is terminated by {0,0}

enum AVPixelFormat *	pix_fmts
	array of supported pixel formats, or NULL if unknown, array is terminated by -1

const int *	supported_samplerates
	array of supported audio samplerates, or NULL if unknown, array is terminated by 0

enum AVSampleFormat *	sample_fmts
	array of supported sample formats, or NULL if unknown, array is terminated by -1

const uint64_t *	channel_layouts
	array of support channel layouts, or NULL if unknown. array is terminated by 0

uint8_t	max_lowres
	maximum value for lowres supported by the decoder, no direct access, use av_codec_get_max_lowres()

const AVClass *	priv_class
	AVClass for the private context.

const AVProfile *	profiles
	array of recognized profiles, or NULL if unknown, array is terminated by {FF_PROFILE_UNKNOWN}

int	priv_data_size

struct AVCodec *	next

const AVCodecDefault *	defaults
	Private codec-specific defaults.

void(*	init_static_data )(struct AVCodec *codec)
	Initialize codec static data, called from avcodec_register().

int(*	init )(AVCodecContext *)

int(*	encode_sub )(AVCodecContext , uint8_t buf, int buf_size, const struct AVSubtitle *sub)

int(*	encode2 )(AVCodecContext avctx, AVPacket avpkt, const AVFrame frame, int got_packet_ptr)
	Encode data to an AVPacket.

int(*	decode )(AVCodecContext , void outdata, int outdata_size, AVPacket avpkt)

int(*	close )(AVCodecContext *)

void(*	flush )(AVCodecContext *)
	Flush buffers.

Frame-level threading support functions
int(*	init_thread_copy )(AVCodecContext *)
	If defined, called on thread contexts when they are created.

int(*	update_thread_context )(AVCodecContext dst, const AVCodecContext src)
	Copy necessary context variables from a previous thread context to the current one.

const char* AVCodec::name

Name of the codec implementation.

The name is globally unique among encoders and among decoders (but an encoder and a decoder can share the same name). This is the primary way to find a codec from the user perspective.
