	Tells video output to embed video in an existing window.
void	StopEmbedding (void)
	Tells video output to stop embedding video in an existing window.

bool VideoOutputNull::Init	(	int	width,
		int	height,
		float	aspect,
		WId	winid,
		int	winx,
		int	winy,
		int	winw,
		int	winh,
		WId	embedid = `0`
	)			`[virtual]`

Performs most of the initialization for VideoOutput.

Returns:: true if successful, false otherwise.

Reimplemented from VideoOutput.

Definition at line 116 of file videoout_null.cpp.

bool VideoOutputNull::SetupDeinterlace	(	bool	i,
		const QString &	ovrf = `""`
	)			`[inline, virtual]`

Attempts to enable or disable deinterlacing.

Returns:: true if successful, false otherwise.

Parameters:

overridefilter

optional, explicitly use this nondefault deint filter

Reimplemented from VideoOutput.

Definition at line 17 of file videoout_null.h.

void VideoOutputNull::PrepareFrame	(	VideoFrame *	buffer,
		FrameScanType	t
	)			`[virtual]`

Implements VideoOutput.

Definition at line 158 of file videoout_null.cpp.

void VideoOutputNull::Show ( FrameScanType ) [virtual]

Implements VideoOutput.

Definition at line 170 of file videoout_null.cpp.

void VideoOutputNull::CreatePauseFrame ( void )

Definition at line 46 of file videoout_null.cpp.

Referenced by Init(), and InputChanged().

bool VideoOutputNull::InputChanged	(	const QSize &	input_size,
		float	aspect,
		MythCodecID	myth_codec_id,
		void *	codec_private
	)			`[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().

Reimplemented from VideoOutput.

Definition at line 70 of file videoout_null.cpp.

void VideoOutputNull::Zoom ( ZoomDirection direction ) [virtual]

Sets up zooming into to different parts of the video, the zoom is actually applied in MoveResize().

Reimplemented from VideoOutput.

Definition at line 39 of file videoout_null.cpp.

void VideoOutputNull::EmbedInWidget	(	WId	wid,
		int	x,
		int	y,
		int	w,
		int	h
	)			`[virtual]`

Tells video output to embed video in an existing window.

Parameters:

	wid	window to embed in.
	x	X location where to locate video
	y	Y location where to locate video
	w	width of video
	h	height of video

Implements VideoOutput.

Definition at line 111 of file videoout_null.cpp.

void VideoOutputNull::DrawUnusedRects ( bool sync = true ) [virtual]
