	ref	a video or audio buffer reference

Returns:

0 in case of success, a negative AVERROR code in case of failure

Deprecated:

Use avfilter_copy_buf_props() instead.

Fill an AVFrame with the information stored in picref.

Parameters:

	frame	an already allocated AVFrame
	picref	a video buffer reference

Returns:

0 in case of success, a negative AVERROR code in case of failure

Deprecated:

Use avfilter_copy_buf_props() instead.
