* Vivante: Keep only one frameVaL Doroshchuk2020-05-151-7/+3
| | | | | | | | | | | | | The imx6 vivante implementation of videonode used by qtvideosink holds reference to two frames during rendering. It releases the first frame only when it receives the third frame. This makes jerky playback when frames are not coming at constant rate. It displays the previous frame during video playback.

* imx: Fallback to copying data if mapping has not succeededVaL Doroshchuk2018-09-251-34/+40
| | | | | | | | | | | | Some formats or data might be unsupported and not possible to use them in glTexDirectVIVMap. If glTexDirectVIVMap returns an error then need to upload data to memory created by the driver using glTexDirectVIV. If at least one such error has occurred, all next video frames will be copied via glTexDirectVIV without trying to map again.

* Add video filtering support to VideoOutputLaszlo Agocs2015-02-031-43/+91
| | | | | | | | | | | | | | | | | | | | | | | | | Add the QAbstractVideoFilter base class and integrate it with VideoOutput. This can be used to perform arbitrary filtering or image processing on the frames of a video stream of a VideoOutput element right before the OpenGL texture is provided to the scenegraph by the video node. This opens up the possibility to integrate computer vision frameworks or accelerated image processing with Qt Quick applications that display video streams using Qt Multimedia. Conceptually it is somewhat similar to QVideoProbe, this approach however allows modifying the frame, in real time with tight integration to the scenegraph node, and targets Qt Quick meaning setting up the filter and processing the results of the computations happen completely in QML. [ChangeLog] Added QAbstractVideoFilter that serves as a base class for QML video filtering elements that integrate compute, vision, and image processing frameworks with VideoOutput.

* adding zero-copy-QSGVideoNode for imx6Thomas Senyk2014-02-111-0/+196
On imx6 there is a platform-specific API to implement memory-mapping from gstreamer-buffer to opengl-texture. This plugin uses this API to avoid CPU-based-memory-copy. This allows fluid video-playback up to 1080p with very little CPU load. Before even 720p used one cpu-core completely and wasn't fluid.
