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. | |
| void *(* | child_next )(void *obj, void *prev) |
| Return next AVOptions-enabled child or NULL. | |
| struct AVClass *(* | child_class_next )(const struct AVClass *prev) |
| Return an AVClass corresponding to next potential AVOptions-enabled child. | |
That is an arbitrary struct of which the first field is a pointer to an AVClass struct (e.g. AVCodecContext, AVFormatContext etc.).

struct AVClass*(* AVClass::child_class_next)(const struct AVClass *prev) [read] |
Return an AVClass corresponding to next potential AVOptions-enabled child.
The difference between child_next and this is that child_next iterates over _already existing_ objects, while child_class_next iterates over _all possible_ children.

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

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
