Typedef Documentation

◆ 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().

Function Documentation

◆ av_videotoolbox_alloc_context()

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().

Returns
the newly allocated context or NULL on failure

◆ av_videotoolbox_default_free()

void av_videotoolbox_default_free ( AVCodecContext avctx)

This function must be called to free the Videotoolbox context initialized with av_videotoolbox_default_init().

Parameters
avctxthe corresponding codec context

◆ av_videotoolbox_default_init()

int av_videotoolbox_default_init ( AVCodecContext avctx)

This is a convenience function that creates and sets up the Videotoolbox context using an internal implementation.

Parameters
avctxthe corresponding codec context
Returns
>= 0 on success, a negative AVERROR code on failure

◆ av_videotoolbox_default_init2()

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.

Parameters
avctxthe corresponding codec context
vtctxthe Videotoolbox context to use
Returns
>= 0 on success, a negative AVERROR code on failure
