Describe 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.).
AVClassCategory AVClass::category |
Category used for visualization (like color) This is only set if the category is equal for all objects using this class. available since version (51 << 16 | 56 << 8 | 100)
Return an AVClass corresponding to the 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.
void*(* AVClass::child_next) (void *obj, void *prev) |
Return next AVOptions-enabled child or NULL
const char* AVClass::class_name |
The name of the class; usually it is the same name as the context structure type to which the AVClass is associated.
AVClassCategory(* AVClass::get_category) (void *ctx) |
Callback to return the category. available since version (51 << 16 | 59 << 8 | 100)
const char*(* AVClass::item_name) (void *ctx) |
A pointer to a function which returns the name of a context instance ctx associated with the class.
int AVClass::log_level_offset_offset |
Offset in the structure where log_level_offset is stored. 0 means there is no such variable
const struct AVOption* AVClass::option |
a pointer to the first option specified in the class if any or NULL
int AVClass::parent_log_context_offset |
Offset in the structure where a pointer to the parent context for logging is stored. For example a decoder could pass its AVCodecContext to eval as such a parent context, which an av_log() implementation could then leverage to display the parent context. The offset can be NULL.
int(* AVClass::query_ranges) (struct AVOptionRanges **, void *obj, const char *key, int flags) |
Callback to return the supported/allowed ranges. available since version (52.12)
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.
