AVCodec Struct Reference
[Core functions/structures.]

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

void(* AVCodec::flush)(AVCodecContext *)

Flush buffers.

Will be called when seeking

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

Referenced by avcodec_open2(), frame_thread_init(), and vdadec_init().

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

Initialize codec static data, called from avcodec_register().

Referenced by avcodec_register().

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.

Referenced by frame_thread_init().

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.

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.
