This is a "pseudo" base class. Basically it's a shared instance
and class structure and a shared set of function between the
two widget. It cannot have it's own type like normal base class
since the one instance will implement GtkGLArea while the other
implements GtkDrawingAreay. To workaround this, the parent instance
and class is a union of both.

In GTK dispose can be called before the last ref is reached. This
happens when you close the container window. The dispose will be
explicitly called, and destroyed notify will be fired. This patch
fixes this race by properly tracking the widget state.
In the sink, we now set the widget pointer to NULL, so the widget

Two things are provided

To use
1. Declare the GstGLVideoItem in qml with an appropriate

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");

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.
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).
The framerate very often is just an indication of the ideal framerate, not the

We need a mechanism in PulseAudio to allow running code outside the
mainloop lock. Then we'd be able to post to the bus (taking the
GST_OBJECT_LOCK), without worrying about locking order with the mainloop
lock, which is the current cause of deadlocks while trying to post the
stream status messages.
https://bugzilla.gnome.org/show_bug.cgi?id=736071
Stream headers are updated whenever ::set_caps is called, so we can't assume
they'll be valid before the message body is written out. We *can* assume that
for queued buffers, but SOUP_MEMORY_STATIC is still wrong for those.
Also, add some debug logging for stream header interactions.
https://bugzilla.gnome.org/show_bug.cgi?id=737771
::render sets a new callback for writing out new buffers only if there aren't
already buffers queued for writing with a previously-scheduled callback.
However, if the previously-scheduled callback is interrupted by a state change
(either manually or due to an error) and there are still buffers in the queue,
restarting the pipeline will result in buffers being queued forever, and no
callbacks will ever be scheduled, and no buffers will be written out.
https://bugzilla.gnome.org/show_bug.cgi?id=737739
This gives a quick introduction to how the pulsesink/pulsesrc code
interacts with the pa_threaded_mainloop that we start up to communicate
with the server.
The stream status messages are emitted in the PA mainloop thread, which
means the mainloop lock is taken, followed by the Gst object lock (by
gst_element_post_message()). In all other locations, the order of
locking is reversed (this is unavoidable in a bunch of cases where the
object lock is taken by GstBaseSink or GstAudioBaseSink, and then we get
control to take the mainloop lock).
The only way to guarantee that the defer callback for stream status
messages doesn't deadlock is to either stop posting those messages, or
make sure that the message emission is completed before we proceed to
any point that might take the object lock before the mainloop lock
(which is what we do after this patch).

getcaps is called frequently during stream setup, and creating a new
stream each time is very inefficient. There's some more room for
optimisation by caching the queried sink formats as well, but this needs

querying).

This allows us to have more fine-tuned caps in READY or above. However,

default by libvpx upstream.

Merging previous commit into current codebase.
Increasing from 1 to 2 threads on an Thinkpad X60s decreased encode time

From libvpx/vp8/encoder/onyx_int.h:
#define MAX_LAG_BUFFERS (CONFIG_REALTIME_ONLY? 1 : 25)
While we don't need to be tied to what libvpx does internally, it
doesn't make sense to pretend to support longer frame lags than are
actually possible.
A public libvpx header includes private headers if this is
defined, causing compilation failures because the private headers
are not installed of course.

When get_time is called but we are not yet negotiated, return 0 instead of
posting an error. It's possible that the base class is still negotiating when
our get_time is called.
This makes sure that we:
a) Destroy an existing stream if a negotiate() request comes in: this is
required when receiving a downstream renegotiation request after a
stream has been created.
b) Create a new stream on prepare(): this is required since we do a
setcaps() in negotiate(), which causes the stream to be dropped by a
ringbuffer release() call (this does not happen during first negotiation
since the release is only done on a running ringbuffer). The subsequent
call to ringbuffer acquire() fails because the stream was lost on
release().

Consider a downstream element that may issue seeks in very short
succession (e.g. queue2), depending on the access pattern of
the downstream element (e.g. qtdemux with audio/video chunks
interleaved so that there's always a sizeable gap between the
current chunks for each stream). In this case, queue2 will maintain
two ranges, and even when it serves a chunk from memory, it will
switch ranges and make souphttpsrc seek to the end of the available
data for that range, assuming that that's where we'll want to
continue reading from next.
This may lead to the following seek request pattern:
- source reading position A
- seek to B
- now reading position still A, requested_postion is B
- streaming thread to be restarted to continue from B
- seek to A, before streaming thread had time to do the seek
- do_seek() now sees reading position == seek position and
returns early.
- however, requested position is still B from the earlier
seek request
- streaming thread starts up, sees that a seek to B is pending
and requests data from B from the server, while the GstBaseSrc
segment has of course been updated/reset to position A, which
was the last seek request.
- we will now send data for position B and pretend that's the
data from position A (via the newsegment event, etc.)
- this causes data corruption
Reproducible doing seek-emulated fast-forward/backward on 006648.
