◆ av_alloc_vdpaucontext()

AVVDPAUContext* av_alloc_vdpaucontext ( void )

◆ av_vdpau_get_surface_parameters()

int av_vdpau_get_surface_parameters	(	AVCodecContext *	avctx,
		VdpChromaType *	type,
		uint32_t *	width,
		uint32_t *	height
	)

Gets the parameters to create an adequate VDPAU video surface for the codec context using VDPAU hardware decoding acceleration.

Note: Behavior is undefined if the context was not successfully bound to a VDPAU device using av_vdpau_bind_context().

Parameters

avctx	the codec context being used for decoding the stream
type	storage space for the VDPAU video surface chroma type (or NULL to ignore)
width	storage space for the VDPAU video surface pixel width (or NULL to ignore)
height	storage space for the VDPAU video surface pixel height (or NULL to ignore)

Returns: 0 on success, a negative AVERROR code on failure.

◆ av_vdpau_alloc_context()

AVVDPAUContext* av_vdpau_alloc_context ( void )

Allocate an AVVDPAUContext.

Returns: Newly-allocated AVVDPAUContext or NULL on failure.

◆ av_vdpau_bind_context()

int av_vdpau_bind_context	(	AVCodecContext *	avctx,
		VdpDevice	device,
		VdpGetProcAddress *	get_proc_address,
		unsigned	flags
	)

Associate a VDPAU device with a codec context for hardware acceleration.

This function is meant to be called from the get_format() codec callback, or earlier. It can also be called after avcodec_flush_buffers() to change the underlying VDPAU device mid-stream (e.g. to recover from non-transparent display preemption).

Note: get_format() must return AV_PIX_FMT_VDPAU if this function completes successfully.
