Member Function Documentation

bool VideoOutputDX::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 160 of file videoout_dx.cpp.

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

Implements VideoOutput.

Definition at line 244 of file videoout_dx.cpp.

void VideoOutputDX::Show ( FrameScanType ) [virtual]

Implements VideoOutput.

Definition at line 323 of file videoout_dx.cpp.

bool VideoOutputDX::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 104 of file videoout_dx.cpp.

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

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

See also:: ToggleAdjustFill(AdjustFillMode)

Reimplemented from VideoOutput.

Definition at line 91 of file videoout_dx.cpp.

void VideoOutputDX::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

See also:: StopEmbedding()

Reimplemented from VideoOutput.

Definition at line 227 of file videoout_dx.cpp.

void VideoOutputDX::StopEmbedding ( void ) [virtual]

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

See also:: EmbedInWidget(WId, int, int, int, int)

Reimplemented from VideoOutput.

Definition at line 236 of file videoout_dx.cpp.

int VideoOutputDX::GetRefreshRate ( void ) [virtual]

Returns current display's frame refresh period in microseconds.

e.g. 1000000 / frame_rate_in_Hz

Implements VideoOutput.

Definition at line 138 of file videoout_dx.cpp.

void VideoOutputDX::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.

Definition at line 435 of file videoout_dx.cpp.

void VideoOutputDX::UpdatePauseFrame ( void ) [virtual]

Updates frame displayed when video is paused.

Implements VideoOutput.

Definition at line 439 of file videoout_dx.cpp.

void VideoOutputDX::ProcessFrame	(	VideoFrame *	frame,
		OSD *	osd,
		FilterChain *	filterList,
		NuppelVideoPlayer *	pipPlayer
	)			`[virtual]`

Implements VideoOutput.

Definition at line 449 of file videoout_dx.cpp.

void VideoOutputDX::MoveResize ( void ) [virtual]

performs all the calculations for video framing and any resizing.

First we apply playback over/underscanning and offsetting, then we letterbox settings, and finally we apply manual scale & move properties for "Zoom Mode".
