| * QNX: Avoid reading frames faster than they're renderedDan Cape2016-04-271-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code would capture frames with a 60Hz timer into two pixmaps alternating pixmaps with each successive frame. Rendering was somewhat disconnected from this, if rendering was unable to occur at 60fps, multiple frames might be copied for each frame rendered. This meant that it might try copying a video frame into a pixmap that was currently being used by the GPU with bad effects. The primary effect being severe flicker on i.mx6 targets. The change is to ensure that we don't read the window data until we're just about to make use of it. This means we don't ever get ahead of ourselves and read the video window once for every frame rendered. The code has been significantly refactored. There is now a class that manages the pixmaps and egl images. This is created on demand and the images are created and destroyed when sizes change. Since this all now occurs in the proper thread, much of the nonsense of setting _q_GLThreadCallback to arrange a call from the render thread is avoided. Remove BlackBerry ifdefs that are no longer used.

* Add new property to QVideoSurfaceFormat.Yoann Lopes2015-08-071-0/+6
| | | | | | | | | | | | The 'mirrored' property indicates the QVideoFrames need to be mirrored along their vertical axis. This is typically needed for video frames coming from a front camera on a mobile device. This is implemented as a string-based property. In Qt 5.6, this should be replaced by a new public function.

* Add an env var to disable OpenGL texture-based video frames.Laszlo Agocs2015-06-031-0/+11
| | | | | | | | | | | | | | | | | | Right now we will always use GLTextureHandle frames with Quick. This is great in many cases, but not always. Applications that wish to examine the frames (e.g. via video filters) will sometimes prefer frames in system memory, even if this is slower to display. Add QT_QUICK_NO_TEXTURE_VIDEOFRAMES which can be used to disable texture-based video frames. [ChangeLog] The environment variable QT_QUICK_NO_TEXTURE_VIDEOFRAMES can now be used to disable OpenGL texture based video frames. This can be useful in applications that wish to filter and process the video frames and are not GPU based.

* Add video filtering support to VideoOutputLaszlo Agocs2015-02-031-5/+109
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix bogus videonode plugin handlingv5.4.0-rc1Laszlo Agocs2014-11-181-4/+19
| | | | | | | | | | | | | | | | Each plugin must provide its own unique key. Otherwise we will only ever see one single plugin. Right now running on i.MX6 is often broken because the imx6 videonode plugin is not picked up since only the egl one is seen by the system. With the fix both plugins provide their own unique key so both become visible. Additionally, introduce a QT_VIDEONODE environment variable. This is useful to specify which plugin to use. This is necessary in case multiple custom videonode plugins support the same formats. Change-Id: Iaa1988f8436dcb938cb9a95e2e0d68a4e92e113c Reviewed-by: Yoann Lopes <yoann.lopes@theqtcompany.com>

* QNX: Remove most of the CPU overhead for video renderingFabian Bumberger2014-04-011-0/+10
| | | | | | | | | | | | | | This patch uses the GL_OES_EGL_image extension to create a OpenGL Texture handle for a libscreen pixmap. If the extension is not available it uses the "old" technique as fallback where the image data is copied into a QImage. This reduces the CPU load by more than 70% and allows HD videos to be played jitter-free.
