void vout_snapshot_Set	(	vout_snapshot_t *	,
		const video_format_t *	,
		const picture_t *
	)

It set the picture used to create the snapshots.

The given picture is only copied and not released. If p_fmt is non NULL it will override the format of the p_picture (mainly used because of aspect/crop problems).
