Render video or camera viewfinder. More...
| Import Statement: | import QtMultimedia |
Rectangle { width: 800 height: 600 color: "black" MediaPlayer { id: player source: "file://video.webm" videoOutput: videoOutput } VideoOutput { id: videoOutput anchors.fill: parent } }
The VideoOutput item supports untransformed, stretched, and uniformly scaled video presentation. For a description of stretched uniformly scaled presentation, see the fillMode property description.
See also MediaPlayer and Camera.
|
contentRect : rectangle |
This property holds the item coordinates of the area that would contain video to render. With certain fill modes, this rectangle will be larger than the visible area of the VideoOutput.
This property is useful when other coordinates are specified in terms of the source dimensions - this applied for relative (normalized) frame coordinates in the range of 0 to 1.0.
Areas outside this will be transparent.
|
fillMode : enumeration |
Set this property to define how the video is scaled to fit the target area.
The default fill mode is PreserveAspectFit.
|
orientation : int |
In some cases the source video stream requires a certain orientation to be correct. This includes sources like a camera viewfinder, where the displayed viewfinder should match reality, no matter what rotation the rest of the user interface has.
This property allows you to apply a rotation (in steps of 90 degrees) to compensate for any user interface rotation, with positive values in the anti-clockwise direction.
The orientation change will also affect the mapping of coordinates from source to viewport.
|
sourceRect : rectangle |
This property holds the area of the source video content that is considered for rendering. The values are in source pixel coordinates, adjusted for the source's pixel aspect ratio.
Note that typically the top left corner of this rectangle will be 0,0 while the width and height will be the width and height of the input content. Only when the video source has a viewport set, these values
will differ.
The orientation setting does not affect this rectangle.
See also QVideoFrameFormat::viewport().

videoSink : object |
This property holds the underlaying C++ QVideoSink object that is used to render the video frames to this VideoOutput element.
Normal usage of VideoOutput from QML should not require using this property.
