Member Function Documentation

bool VideoOutputQuartz::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 1203 of file videoout_quartz.cpp.

void VideoOutputQuartz::SetVideoFrameRate ( float playback_fps ) [virtual]

Reimplemented from VideoOutput.

Definition at line 1391 of file videoout_quartz.cpp.

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

If we are using DVDV hardware acceleration, decodes the frame.

Otherwise, just makes sure we have a valid frame to show.

Implements VideoOutput.

Definition at line 1617 of file videoout_quartz.cpp.

void VideoOutputQuartz::Show ( FrameScanType t ) [virtual]

Display the frame, using either DVDV hardware acceleration, or possibly several UI output types.

See also:: VideoOutputQuartzView

Implements VideoOutput.

Definition at line 1634 of file videoout_quartz.cpp.

bool VideoOutputQuartz::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 1133 of file videoout_quartz.cpp.

void VideoOutputQuartz::VideoAspectRatioChanged ( float aspect ) [virtual]

Calls SetVideoAspectRatio(float aspect), then calls MoveResize() to apply changes.

Parameters:

aspect

video aspect ratio to use

Reimplemented from VideoOutput.

Definition at line 1100 of file videoout_quartz.cpp.

void VideoOutputQuartz::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".

Reimplemented from VideoOutput.

Definition at line 1120 of file videoout_quartz.cpp.

Referenced by Init(), InputChanged(), and Zoom().

void VideoOutputQuartz::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 1112 of file videoout_quartz.cpp.

void VideoOutputQuartz::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

Reimplemented from VideoOutput.

Definition at line 1550 of file videoout_quartz.cpp.

void VideoOutputQuartz::StopEmbedding ( void ) [virtual]

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

Reimplemented from VideoOutput.

Definition at line 1581 of file videoout_quartz.cpp.

int VideoOutputQuartz::GetRefreshRate ( void ) [virtual]

Returns current display's frame refresh period in microseconds.

e.g. 1000000 / frame_rate_in_Hz

Implements VideoOutput.

Definition at line 1195 of file videoout_quartz.cpp.

void VideoOutputQuartz::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 1653 of file videoout_quartz.cpp.

void VideoOutputQuartz::UpdatePauseFrame ( void ) [virtual]

Updates frame displayed when video is paused.

Implements VideoOutput.

Definition at line 1657 of file videoout_quartz.cpp.

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

Draw OSD, apply filters and deinterlacing, copy frame buffer if using QuickTime to decode.

Implements VideoOutput.
