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

Checking for a parent is not enough, it must have a toplevel one.
If widget has no toplevel parent then add it in a GtkWindow, that
make it usable from gst-launch-1.0.

Moved gst_mpd_client_get_next_segment_availability_end_time and
gst_mpd_client_add_time_difference functions to be grouped with
functions from the same category.

Corrected the initialisation of mimeType in
gst_mpdparser_get_list_and_nb_of_audio_language: the variable is used
in a loop, so it must be set to NULL at the beginning of each iteration.

Before returning the next fragment duration value, the
gst_mpd_client_get_next_fragment_duration function tries to validate it.
But the condition was incorrect.
https://bugzilla.gnome.org/show_bug.cgi?id=751539
We're interested in the offset between the period start timestamp and the
actual media timestamp so that we can properly correct for it. The absolute
presentation offset to timestamp 0 is useless as the only thing we really
care about is the offset between the current fragment timestamp and the
media timestamp.
Otherwise we will look for segments after the period usually. The seek
timestamp is relative to the start of the first period and we have to
select a segment relative to the current period's start.
We didn't do this for fragments that are generated on demand from a template,
only for the other cases when they were all generated upfront. This caused
fragment timestamps to start from 0 again for each new period.
If not set, the timeShiftBufferDepth has a default value of -1.
The standard says that this should be interpreted as infinite.
The gst_mpd_client_check_time_position function incorrectly compares
timeShiftBufferDepth with 0 instead of -1 to determine if it was set.

The last parameter of gst_mpd_client_add_media_segment function is a
duration. But when called from gst_mpd_client_setup_representation, the
last argument was wrongly set to PeriodEnd
https://bugzilla.gnome.org/show_bug.cgi?id=751449
The period start information, calculated in gst_mpd_client_setup_media_presentation
function is stored in stream_period->start. The information read from
xml file and stored in stream_period->period->start is not changed.
If the xml file does not contain the period start information,
stream_period->period->start will be -1.
The function gst_mpd_client_get_next_segment_availability_end_time wants to
use period start time, but incorrectly uses stream_period->period->start
(value from xml file, which could be -1) instead of stream_period->start
(computed value)
https://bugzilla.gnome.org/show_bug.cgi?id=751465
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.

Support video with multiview info in the caps, transform
it to mono anaglyph by default, but allow for configuring
other output modes and handoff to the app via
the draw signal.

Added some warning messages in gst_mpd_client_setup_streaming to help
debug situations when the function will return FALSE.
Renamed a wrongly spelled variable.
https://bugzilla.gnome.org/show_bug.cgi?id=751149
Corrected some comments in gstmpdparser.h file.
Moved gst_mpd_client_get_adaptation_sets function to be grouped with
other functions from AdaptationSet group

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.

Getting the current viewport and modifying it relatively will produce an
interesting feedback loop during widget resizing. Over a few frames we
will gradually move the viewport a bit until it converged again, adding
unnecessary additional borders at the top and left.
We now know that pool caching can cause renegotiation issues
when an element in the pipeline change from passthrough to not
passthrough. As it's not needed, don't cache existing pools.

Added a check for a_node->ns before accessing a_node->ns->href in
gst_mpdparser_get_xml_node_namespace. This could happen if the xml
is missing the default namespace.

If the presentationTimeOffset attribute of a DASH manifest contains
a value that is larger than 2^32, gstmpdparser incorrectly calculates
the stream's presentation time offset. This is due to two bugs:
1: Using gst_mpdparser_get_xml_prop_unsigned_integer rather than
gst_mpdparser_get_xml_prop_unsigned_integer_64 to parse the
attribute
2: gst_mpd_client_setup_representation multiplying the value by
GST_SECOND and then dividing by timescale

This patch allow going gst-inspect-1.0 on these elements removing
ugly crash that was previously occurring. The method consist of
making the widget creation as lazy as possible. This way we don't
endup doing gtk_init() before the application. We also ref_sink()
the widget, so we don't crash if the parent widget is discarded,
and cleanly error out with GL if the widget has no parent window,
because calling gtk_widget_realized() can only be done if the widget
has been parented to a window).
This reverts commit 4ca3a22b6b.
The connection-speed=0 is used as a special value in the property
of hlsdemux to mean 'automatic' selection, m3u8.c doesn't need
to know about that as it should be as simple as possible.
So this patch hides this automatic selection documented in hlsdemux
into m3u8 logic and I think the gets harder to understand the code.
It also makes the hlsdemux unit tests work again

This reverts commit 37011e5198.
This change was actually completely unnecessary, the streams in question are
marked as static and are not considered live anyway.
