* Used by av_log
* Describes the class of an AVClass context structure, that is an
* arbitrary struct of which the first field is a pointer to an
* AVClass struct (e.g. AVCodecContext, AVFormatContext etc.).
typedef struct AVCLASS AVClass;
struct AVCLASS {
* the name of the class, usually it is the same name of the
* context structure type to which the AVClass is associated
const char* class_name;
const char* (*item_name)(void*); /* actually passing a pointer to an AVCodecContext
or AVFormatContext, which begin with an AVClass.
Needed because av_log is in libavcodec and has no visibility
of AVIn/OutputFormat */
* a pointer to a function which returns the name of a context
* instance \p ctx associated with the class
const char* (*item_name)(void* ctx);
* a pointer to the first option specified in the class if any or NULL
* @see av_set_default_options()
const struct AVOption *option;
