Field Documentation

◆ name

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.

Examples: transcode.c.

◆ long_name

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.

◆ max_lowres

uint8_t AVCodec::max_lowres

maximum value for lowres supported by the decoder

Referenced by ff_decode_preinit(), and stream_component_open().

◆ priv_class

const AVClass* AVCodec::priv_class

AVClass for the private context.

◆ profiles

const AVProfile* AVCodec::profiles

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

Definition at line 198 of file codec.h.

Referenced by av_get_profile_name().

◆ wrapper_name

const char* AVCodec::wrapper_name

Group name of the codec implementation.

This is a short symbolic name of the wrapper backing this codec. A wrapper uses some kind of external implementation for the codec, such as an external library, or a codec implementation provided by the OS or the hardware. If this field is NULL, this is a builtin, libavcodec native codec. If non-NULL, this will be the suffix in AVCodec.name in most cases (usually AVCodec.name will be of the form "<codec_name>_<wrapper_name>").
