5d22e0c8d0 examples/gl/qt: fix the examples for the use of newer API
gstgl doesn't undo/overwrite what GL state the examples are changing
anymore.  As such, the examples need to reset the GL state themselves
to be able to play nice with libgstgl

8c9ca808af gstreamer: bad: Fix memory leaks when context parse fails
When g_option_context_parse fails, context and error variables are not getting free'd
which results in memory leaks. Free'ing the same.

And replacing g_error_free with g_clear_error, which checks if the error being passed
is not NULL and sets the variable to NULL on free'ing.

697f117ddd configure.ac: fix build when the uvch264 plugin is not selected
Instead of checking for the gstreamer-video-1.0 package is installed,
just assume it is since we already check for the -base dependency.

With this replace the GST_VIDEO_* variables in makefiles and directly
link with libgstvideo.

loud accidentally. Only create variables when needed.

02b9daafdf facedetect: Add unit test
I created four utilities of the detected features:
1- If you hide your mouth, the volume of video is low.
2- If you hide the nose, the volume of the video is up.
3- If you hide the full face, the video stops.

You can see proof of this here:

769fffa3d9 new qt5 qml GL video sink
Very much in the same spirit as the Gtk GL sink

Two things are provided
1. A QQuickItem subclass that renders out RGBA filled GstGLMemory
   buffers that is instantiated from qml.
2. A sink element that will push buffers into (1)

To use
1. Declare the GstGLVideoItem in qml with an appropriate
   objectName property set.
2. Get the aforementioned GstGLVideoItem from qml using something like

QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

QObject *rootObject = engine.rootObjects().first();
QQuickItem *videoItem = rootObject->findChild<QQuickItem *> ("videoItem");

3. Set the videoItem on the sink

5da10b4f57 playout: New example for seamless audio/video playback
An example app that takes video URIs as command line arguments and switches
between them seamlessly one after the other using compositor and audiomixer.
Both audio-video and video-only media files are valid inputs, but mixing files
of both types in a single invocation is cumbersome to support, and hence does
not work. The example attempts to keep the audio stream moving along perfectly,
and duplicates video frames where necessary to cover gaps in the video
timestamps using the 'ignore-eos' videoaggregator pad property.

Ensuring seamless (and mostly-glitch-free) switching is harder than it sounds,
and hence the example contains plenty of pad probes and running time
calculations to make things work.

The GPtrArray play_queue contains items that are being played back, have been
prepared for playback, and will be played back in the future. The queue itself
is mutable besides the first two items (playing and prepared). The item that has
been prepared should not be edited or removed since it has been prepared in
advance to be activated immediately on the current item's EOS.

The example also has support for switching to the next item in the queue
prematurely; see the --switch-after/-s flag to the application.

Note: the output video is hard-coded at 1280x720, and input video is scaled as
needed to fit this size. Set OUTPUT_VIDEO_WIDTH/HEIGHT to change this.

1f9bdcad87 gstgtk: Don't leak the widget
g_object_get() returns a ref, gtk_container_add() only ref_sink().
That mean we still need to unref afterward. This leak was hiding
a reference bug previously present.
