Data Fields | |
| const char * | class_name |
| The name of the class; usually it is the same name as the context structure type to which the AVClass is associated. | |
| const char *(* | item_name )(void *ctx) |
| A pointer to a function which returns the name of a context instance ctx associated with the class. | |
| struct AVOption * | option |
| a pointer to the first option specified in the class if any or NULL | |
| int | version |
| LIBAVUTIL_VERSION with which this structure was created. | |
| int | log_level_offset_offset |
| Offset in the structure where log_level_offset is stored. | |
| int | parent_log_context_offset |
| Offset in the structure where a pointer to the parent context for loging is stored. | |
| struct AVOption *(* | opt_find )(void *obj, const char *name, const char *unit, int opt_flags, int search_flags) |
| A function for extended searching, e.g. | |
That is an arbitrary struct of which the first field is a pointer to an AVClass struct (e.g. AVCodecContext, AVFormatContext etc.).

| const char* AVClass::class_name |
| const char*(* AVClass::item_name)(void *ctx) |

struct AVOption*(* AVClass::opt_find)(void *obj, const char *name, const char *unit, int opt_flags, int search_flags) [read] |
struct AVOption* AVClass::option [read] |
Offset in the structure where a pointer to the parent context for loging is stored.
for example a decoder that uses eval.c could pass its AVCodecContext to eval as such parent context. And a av_log() implementation could then display the parent context can be NULL of course

| int AVClass::version |
LIBAVUTIL_VERSION with which this structure was created.
This is used to allow fields to be added without requiring major version bumps everywhere.
