typedef struct AVVideotoolboxContext AVVideotoolboxContext |
This struct holds all the information that needs to be passed between the caller and libavcodec for initializing Videotoolbox decoding. Its size is not a part of the public ABI, it must be allocated with av_videotoolbox_alloc_context() and freed with av_free().
AVVideotoolboxContext* av_videotoolbox_alloc_context | ( | void | ) |
Allocate and initialize a Videotoolbox context.
This function should be called from the get_format() callback when the caller selects the AV_PIX_FMT_VIDETOOLBOX format. The caller must then create the decoder object (using the output callback provided by libavcodec) that will be used for Videotoolbox-accelerated decoding.
When decoding with Videotoolbox is finished, the caller must destroy the decoder object and free the Videotoolbox context using av_free().
void av_videotoolbox_default_free | ( | AVCodecContext * | avctx | ) |
This function must be called to free the Videotoolbox context initialized with av_videotoolbox_default_init().
avctx | the corresponding codec context |
int av_videotoolbox_default_init | ( | AVCodecContext * | avctx | ) |
This is a convenience function that creates and sets up the Videotoolbox context using an internal implementation.
avctx | the corresponding codec context |
int av_videotoolbox_default_init2 | ( | AVCodecContext * | avctx, |
AVVideotoolboxContext * | vtctx | ||
) |
This is a convenience function that creates and sets up the Videotoolbox context using an internal implementation.
avctx | the corresponding codec context |
vtctx | the Videotoolbox context to use |
