AVHWAccel* ff_find_hwaccel	(	enum CodecID	codec_id,
		enum PixelFormat	pix_fmt
	)

Return the hardware accelerated codec for codec codec_id and pixel format pix_fmt.

Parameters:

	codec_id	the codec to match
	pix_fmt	the pixel format to match

Returns:

the hardware accelerated codec, or NULL if none was found.

int ff_match_2uint16	(	const uint16_t(*)	tab[2],
		int	size,
		int	a,
		int	b
	)

Return the index into tab at which {a,b} match elements {[0],[1]} of tab.

If there is no such matching pair then size is returned.
