void VideoOutputNull::GetRenderOptions	(	render_opts &	opts,
		QStringList &	cpudeints
	)			`[static]`

bool VideoOutputNull::Init	(	int	width,
		int	height,
		float	aspect,
		WId	winid,
		const QRect &	win_rect,
		MythCodecID	codec_id
	)			`[virtual]`

Reimplemented from VideoOutput.

Definition at line 134 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,
		OSD *	osd
	)			`[virtual]`

Implements VideoOutput.

Definition at line 185 of file videoout_null.cpp.

void VideoOutputNull::Show ( FrameScanType ) [virtual]

Implements VideoOutput.

Definition at line 197 of file videoout_null.cpp.

void VideoOutputNull::CreatePauseFrame ( void )

Definition at line 60 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,
		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().

Reimplemented from VideoOutput.

Definition at line 79 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 53 of file videoout_null.cpp.

void VideoOutputNull::EmbedInWidget ( const QRect & rect ) [virtual]

Tells video output to embed video in an existing window.

See also:: StopEmbedding()

Reimplemented from VideoOutput.

Definition at line 171 of file videoout_null.cpp.

void VideoOutputNull::StopEmbedding ( void ) [virtual]

Tells video output to stop embedding video in an existing window.

Reimplemented from VideoOutput.

Definition at line 178 of file videoout_null.cpp.

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

Draws non-video portions of the screen.

Parameters:

sync

if set any queued up draws are sent immediately to the graphics context and we block until they have completed.

Implements VideoOutput.
