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.
