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.

Definition at line 194 of file codec.h.

Referenced by avcodec_get_name(), avcodec_open2(), avcodec_string(), choose_pixel_fmt(), context_to_name(), cuvid_test_capabilities(), dec_thread_set_name(), dshow_cycle_formats(), find_codec(), find_codec_by_name(), hw_device_setup_for_decode(), init(), main(), ost_add(), print_codecs(), print_codecs_for_id(), print_stream_maps(), show_codecs(), thread_set_name(), and video_decode().

◆ 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.

Definition at line 199 of file codec.h.

◆ type

enum AVMediaType AVCodec::type

◆ id

enum AVCodecID AVCodec::id

◆ 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>").

Array of supported channel layouts, terminated with a zeroed layout.

Examples: encode_audio.c.

Definition at line 237 of file codec.h.
