* gsttools: use nullptr instead of NULLRolf Eike Beer2020-01-061-23/+23

* Gstreamer: Introduce support of OpenGL pluginVaL Doroshchuk2019-05-151-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since uploading to gl texture is quite performance-wise operation introduced integration of opengl plugin which can provide a way to avoid uploading to texture on each draw on qt's side. Which potentially fixes some performance issues especially on embedded devices. Added glupload and glcolorconvert gst elements to pipeline. For qml apps current opengl context is provided to the gst plugin to share opengl data with. It allows at the end to just use gl textures that created and filled inside the gst. For overlay apps, glimagesink element is added. Requires gstreamer-gl-1.0 to be installed. Since this plugin is almost always available, so enabling it by default will break behavior of current pipeline and might introduce some side effects. Thus also provided QT_GSTREAMER_USE_OPENGL_PLUGIN env var to explicitly enable OpenGL features from gst. After this change video frames will be texture based. But it is still possible to map frames to download their data. In case if the video surface does not support gl textures, glmemory will be anyway requested, which will lead to uploading data, downloading and uploading it again to textures in scene graph video node.

* Gstreamer: Introduce custom pipelineVaL Doroshchuk2018-08-301-18/+29
| | | | | | | | | | | | | | | | | | | | | | Added an ability to define custom pipeline. Since new pipeline is used, playbin features will not work. Registered "qtvideosink" gstreamer element to be used in pipelines. In case if there is a need to render to QML VideoOutput element. I.e. if a pipeline is "videotestsrc ! qtvideosink" then QGstVideoRendererSink will be used as a sink and rendering will be done by one of QSGVideoNode's. In this case there is a need to create a pipeline after video surface is ready. Also added an ability to override default video sink and define custom one instead. QGstreamerVideoRendererInterface::setVideoSink() provides functionality to override default one. QGstreamerPlayerSession::rendererChanged() can be used to check if the renderer is ready to create a pipeline or set custom video sink.

* Gstreamer: Fix setting vaapi sink propertiesVaL Doroshchuk2018-03-211-107/+288
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since vaapi and xvimage sinks require different ranges for the properties: brightness, contrast, hue, saturation. Added support of vaapi ranges. It also fixes problem when contrast was always 0 as default value which led to always show black screen. - brightness xvimage: Allowed values: [-1000,1000], Default value: 0 vaapi: Allowed values: [-1,1], Default value: 0 - contrast xvimage: Allowed values: [-1000,1000], Default value: 0 vaapi: Allowed values: [0,2], Default value: 1 - hue xvimage: Allowed values: [-1000,1000], Default value: 0 vaapi: Allowed values: [-180,180], Default value: 0 - saturation xvimage: Allowed values: [-1000,1000], Default value: 0 vaapi: Allowed values: [0,2], Default value: 1 Task-number: QTBUG-23761 Change-Id: I8fda8ce4c6f47c4567e67c670f802a0e9f55af6e Reviewed-by: Christian Stromme <christian.stromme@qt.io>

* GStreamer: fix compilation with version < 0.10.31.Yoann Lopes2015-10-201-6/+9
| | | | | | | | | | Qt 5.4 and earlier required GStreamer 0.10.24 as minimum version. Qt 5.5 added code that requires 0.10.31, this code is now ifdef'd and we now support again 0.10.24.

* GStreamer: refactored widget and window control.Yoann Lopes2015-08-181-0/+429
| | | | | | | | | | | | | | | | | | | Instead of always using xvimagesink as GStreamer backend for the widget and window control (works only with X11), we now try to pick a video sink that fits the current configuration. It first tries a set of known video sinks that can work with the Qt platform plugin in use. If none is available, it dynamically picks a video sink available on the system that can be used with our backend. Even if the video sink is now picked in a smarter way, xcb is still the only supported platform plugin. The reason is that it's the only Unix plugin which can provide a valid native window handle. Additional work is needed to support other plugins like wayland or directfb. Change-Id: I3843dea363d6a0b85a6cc1f2952783b743e48ac6 Reviewed-by: Christian Stromme <christian.stromme@theqtcompany.com>
* Some cleanup in the GStreamer plugin.Yoann Lopes2013-09-201-228/+0
| | | | | | | | | | | | Removed QGstreamerVideoOverlay and related classes. It was used as 'Window' control but performs worse than QGstreamerVideoWindow which does basically the same thing using GStreamer ready-made components instead. Removed X11 dependencies and related configuration tests. It was only needed for QGstreamerVideoOverlay.

* Split gstreamer plugin into smaller plugins providing fewer servicesJonas Rabbe2012-04-271-0/+228
The gstreamer blob has been split into four plugins: audiodecoder, camerabin, mediacapture, and mediaplayer. Note: camerabin is still disabled because it is untested camerabin2 implementation. A new qmake configuration use_gstreamer_camera has been introduced and is needed for the mediacapture plugin to expose the camera service. This configuration has been disabled by default. Shared functionality has been moved to the internal gsttools library. Change-Id: Ifb2604f440cfa97513d39f5d7978766c88eaec45 Reviewed-by: Michael Goddard <michael.goddard@nokia.com>
