		float	aspect,
		MythCodecID	myth_codec_id,
		void *	codec_private,
		bool &	aspect_only
	)			[virtual]

Tells video output to discard decoded frames and wait for new ones.

Bug:

We set the new width height and aspect ratio here, but we should do this based on the new video frames in Show().

const [virtual]

Approves bobdeint filter for XVideo and otherwise defers to VideoOutput::ApproveDeintFilter(const QString&).

Approves all deinterlace filters, except ones which must be supported by a specific video output class.

Returns:

whether current video output supports a specific filter.
