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.

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::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>").
const AVChannelLayout* AVCodec::ch_layouts |
Array of supported channel layouts, terminated with a zeroed layout.
