Detailed Description

AVCodec.

Examples:: decoding_encoding.c, demuxing_decoding.c, filtering_audio.c, filtering_video.c, muxing.c, transcode_aac.c, and transcoding.c.

Field Documentation

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.

Definition at line 3479 of file avcodec.h.

const char* AVCodec::long_name

Descriptive name for the codec, meant to be more human readable than name.

You should use the NULL_IF_CONFIG_SMALL() macro to define it.

Definition at line 3484 of file avcodec.h.

enum AVMediaType AVCodec::type

Definition at line 3485 of file avcodec.h.

enum AVCodecID AVCodec::id

Definition at line 3486 of file avcodec.h.

int AVCodec::capabilities

Codec capabilities.

see AV_CODEC_CAP_*

const AVRational* AVCodec::supported_framerates

array of supported framerates, or NULL if any, array is terminated by {0,0}

Definition at line 3492 of file avcodec.h.

enum AVPixelFormat* AVCodec::pix_fmts

array of supported pixel formats, or NULL if unknown, array is terminated by -1

Examples:: transcoding.c.

const int* AVCodec::supported_samplerates

array of supported audio samplerates, or NULL if unknown, array is terminated by 0

enum AVSampleFormat* AVCodec::sample_fmts

uint8_t AVCodec::max_lowres

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

Definition at line 3497 of file avcodec.h.

const AVClass* AVCodec::priv_class

AVClass for the private context.

Definition at line 3498 of file avcodec.h.

const AVProfile* AVCodec::profiles

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

Definition at line 3499 of file avcodec.h.

int AVCodec::priv_data_size

Definition at line 3508 of file avcodec.h.

struct AVCodec* AVCodec::next

Definition at line 3509 of file avcodec.h.

int(* AVCodec::init_thread_copy)(AVCodecContext *)

If defined, called on thread contexts when they are created.

If the codec allocates writable tables in init(), re-allocate them here. priv_data will be set to a copy of the original.

Definition at line 3519 of file avcodec.h.

int(* AVCodec::update_thread_context)(AVCodecContext *dst, const AVCodecContext *src)

Copy necessary context variables from a previous thread context to the current one.

If not defined, the next thread will start automatically; otherwise, the codec must call ff_thread_finish_setup().

dst and src will (rarely) point to the same context, in which case memcpy should be skipped.

Definition at line 3527 of file avcodec.h.

const AVCodecDefault* AVCodec::defaults

Private codec-specific defaults.

Definition at line 3533 of file avcodec.h.

void(* AVCodec::init_static_data)(struct AVCodec *codec)

Initialize codec static data, called from avcodec_register().

int(* AVCodec::init)(AVCodecContext *)

Definition at line 3540 of file avcodec.h.

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

Definition at line 3541 of file avcodec.h.

int(* AVCodec::encode2)(AVCodecContext *avctx, AVPacket *avpkt, const AVFrame *frame, int *got_packet_ptr)

Encode data to an AVPacket.

Parameters

	avctx	codec context
	avpkt	output AVPacket (may contain a user-provided buffer)
[in]	frame	AVFrame containing the raw data to be encoded
[out]	got_packet_ptr	encoder sets to 0 or 1 to indicate that a non-empty packet was returned in avpkt.

Returns: 0 on success, negative error code on failure
