Functions | |
| const char * | av_get_colorspace_name (enum AVColorSpace val) |
| Get the name of a colorspace. | |
| AVFrame * | av_frame_alloc (void) |
| Allocate an AVFrame and set its fields to default values. | |
| void | av_frame_free (AVFrame **frame) |
| Free the frame and any dynamically allocated objects in it, e.g. | |
| int | av_frame_ref (AVFrame *dst, const AVFrame *src) |
| Set up a new reference to the data described by the source frame. | |
| AVFrame * | av_frame_clone (const AVFrame *src) |
