We need to sync the pad values before taking the aggregator and pad locks
otherwise the element will just deadlock if there's any property changes
scheduled using GstController since that involves taking the aggregator and pad
locks.
Also add a test for this.

They require to get_proc_address some functions through the
platform specific {glX,egl}GetProcAddress rather than the default
GL library symbol lookup.
The previous approach of traversing the other_context weak ref tree was
1. Less performant
2. Incorrect for context destruction removing a link in the tree
Example of 2:
c1 = context_create (NULL)
c2 = context_create (c1)
c3 = context_create (c2)
context_can_share (c1, c3) == TRUE
context_destroy (c2)
unref (c2)
context_can_share (c1, c3) returns FALSE when it should be TRUE!
This does not remove the restriction that context sharedness can only
be tracked between GstGLContext's.
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

flexelint (http://www.gimpel.com/html/flex.htm) static code analyser
complained about implicit conversions from unsigned to signed, so I added
explicit conversions.
Ideally, the size parameter of gst_mpd_parse function should be unsigned,
but I don't want to change the API.
The duration_to_ms function converts a time specified by year, month, day,
hour, minute, second, millisecond to a millisecond value. Because all the
arguments are positive numbers, the result must also be positive.
This patch changes the returned value from a gint64 to a guint64 type.
Improved dash_mpd unit tests by adding new tests that parse the Period element.
Code coverage reported by lcov for dash/gstmpdparser.c is:
lines......: 43.0% (985 of 2290 lines)
functions..: 47.5% (67 of 141 functions)
According to ISO/IEC 23009-1:2014(E), chapter 5.3.2.1
"The Period extends until the PeriodStart of the next Period, or until
the end of the Media Presentation in the case of the last Period."
This means that a configured value for optional attribute period duration
should be ignored if the next period contains a start attribute or it is
the last period and the MPD contains a mediaPresentationDuration attribute.

The gst_mpdparser_get_rep_idx_with_max_bandwidth function assumes
representations are ordered by bandwidth and incorrectly returns the
first one when wanting the one with minimum bandwidth.
Corrected gst_mpdparser_get_rep_idx_with_max_bandwidth function to get the
correct representation in case max_bandwidth parameter is 0.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=748947
When the 'ignore-eos' property is set on a pad, compositor will keep resending
the last buffer on the pad till the pad is unlinked. We count the buffers
received on appsink, and if it's more than the buffers sent by videotestsrc, the
test passes.
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.
Lets not cram everything into a single test - this would render the test name
useless for quick diagnosis. Having separate tests for the optional feature is
also verifying the behaviour when the feature is off.
Rather than one of the input pad video info's.
The test checking this was not constraining the output frame size
to ensure that the out of frame stream was not being displayed.
We verify that all the buffers on an obscured sinkpad are skipped by overriding
the map() function in the GstVideoMeta of the buffers to set a variable when
called. We also test that the buffers do get mapped when they're not obscured.
Blame^WCredit for the GstVideoMeta map() idea goes to Tim.

If 95% of the code of an example app consists of GObject
code, maybe that's defeating the point a little. So just
remove a lot of that and trim down the example to the
absolute minimum. Also removes the last remaining GPL3
licensed code in -bad.
GstPhotography enables new paths in wrappercamerabinsrc that allows
the source to be notified about the capture caps and provide an
alternative caps if desired bypassing the negotiation (this doesn't
seem like a good idea these days). To make sure it keeps working
until we remove it from the API in favor of standard caps negotiation
features this test was added.
It adds 3 extra tests with a simple test source that will:
1) Test that capturing with ANY caps work
2) Test that capturing with a fixed caps work
3) Test that capturing with a fixed caps and having the source
pick a different resolution from GstPhotography API works
by having wrappercamerabinsrc crop the capture to the final
requested dimensions
A bitmask is 64 bits, but integer immediates are passed as int
in varargs, which happen to be 32 bit with high probability.
This triggered a valgrind jump-relies-on-uninitalized-value
report well away from the site, since it doesn't trigger on
stack accesses, and there must have been enough zeroes to stop
g_object_set at the right place.
The first output MPEG-TS packet that corresponds to a video input
buffer which had the delta flag cleared (i.e. was a keyframe)
should have the delta flag cleared as well.
This is needed e.g. by tcpserversink in order to keep track
of the last keyframe and be able to burst data to newly-
connected clients.

This reverts commit 1c77d12ce8.
"interlaced" in the caps don't mean the same thing as the SOF2 marker in the
JPEG format. This test passes because of broken behaviour.
The flush stop could have happened between the source trying
to push the segment event and the buffer, this would cause a warning.
Prevent that by taking the source's stream lock while flushing.

With the current audiomixer, the input caps need to be the same,
otherwise there is an unavoidable race in the caps negotiation. So
enforce that using capsfilters

Get rid of now-useless packetizer struct and just
call internal functions directly. Also remove
version property which is now defunct, not least
because we create the packetizer with the
version in the init function before a version
can be set.
When this is TRUE, we really have to produce output. This happens
in live mixing mode when we have to output something for the current
time, no matter if we have enough input or not.
Using NSApp directly seems to confuse something, as the compiler
was expecting an id<NSFileManagerDelegate>. Switched to using
[NSApplication sharedApplication], and specified the delegate
protocol on the window class as well.

This still has some unit tests for alternative renditions and

support them properly.
1. glcontextid function is replaced by gstreamer gst_gl_context_new_wrapped .
2. call gst_init before gst_gl_display_new , seems gst_gl_display_new depends
on gst_allocator_register , which only worked after gst_init called
3. flush gstreamer OpenGL context before using shared texture, fix

It was previously a mix and match of both variants, introducing just too much
confusion.
The prefix are from now on:
* GstMpegts for structures and type names (and not GstMpegTs)
* gst_mpegts_ for functions (and not gst_mpeg_ts_)
* GST_MPEGTS_ for enums/flags (and not GST_MPEG_TS_)
* GST_TYPE_MPEGTS_ for types (and not GST_TYPE_MPEG_TS_)
The rationale for chosing that is:
* the namespace is shorter/direct (it's mpegts, not mpeg_ts nor mpeg-ts)
* the namespace is one word under Gst
* it's shorter (yah)
The reshape property was never used.
Replace the draw property with a signal.
