int av_vdpau_get_profile	(	AVCodecContext *	avctx,
		VdpDecoderProfile *	profile
	)

Get a decoder profile that should be used for initializing a VDPAU decoder.

Should be called from the AVCodecContext.get_format() callback.

Parameters

avctx	the codec context being used for decoding the stream
profile	a pointer into which the result will be written on success. The contents of profile are undefined if this function returns an error.

Returns

0 on success (non-negative), a negative AVERROR on failure.

(

void

)

Allocate an AVVDPAUContext.

Returns

Newly-allocated AVVDPAUContext or NULL on failure.
