AVFilterBufferRef* avfilter_get_video_buffer_ref_from_arrays	(	uint8_t *	data[4],
		int	linesize[4],
		int	perms,
		int	w,
		int	h,
		enum AVPixelFormat	format
	)

Create a buffer reference wrapped around an already allocated image buffer.

Parameters

data	pointers to the planes of the image to reference
linesize	linesizes for the planes of the image to reference
perms	the required access permissions
w	the width of the image specified by the data and linesize arrays
h	the height of the image specified by the data and linesize arrays
format	the pixel format of the image specified by the data and linesize arrays

AVFilterBufferRef* ff_get_video_buffer	(	AVFilterLink *	link,
		int	perms,
		int	w,
		int	h
	)

Request a picture buffer with a specific set of permissions.

Parameters

link	the output link to the filter from which the buffer will be requested
perms	the required access permissions
w	the minimum width of the buffer to allocate
h	the minimum height of the buffer to allocate

Returns: A reference to the buffer. This must be unreferenced with avfilter_unref_buffer when you are finished with it.
