When scanning for SCR / PTS / DTS, handle the case where
the pack header is followed by the optional system header,
so we can correctly collect timestamps in such cases.
https://bugzilla.gnome.org/show_bug.cgi?id=623860
When the file size is smaller than the configured 4MB scan
limit for timestamps, don't underflow the guard variable
when checking if it's time to stop.
Limit the backward SCR scan to the same 4MB as the PTS scan.
Add some comments.
In OpenBSD there is no "actual" librt that programs can link with,
instead the system/base libc provides the functions one would
customarily find there.

We can avoid a render pass if downstream supports the affine transformation meta
and increase the performance of some pipelines involving gltransformation.
Implemented by checking for the affine transformation in the allocation query
from downstream and combining our matrix with that of upstream's (or creating
our own).
Provide a function to get the affine matrix in the meta in terms of NDC
coordinates and use as a standard opengl matrix.
Also advertise support for the affine transformation meta in the allocation
query.
We were always failing the allocation query as a flag was never being set to
signal a successful negotiation. Fix by setting the required flag on a
successful caps event from upstream.
The port was trivial, and according to the NEWS file nothing else has changed,
but it is possible that other API was changed without proper notification.
OpenJPEG upstream has shipped a pkg-config file for the past 4 years, and all
distros should be shipping it by now.

When there's no explicit delivery system information
for a channel in the channel configuration file and
the user hasn't selected one via setting the delsys
property, we *guessed* it by selecting the last
supported delsys reported by the driver. This change
provides the basis for smarter delsys auto detection
and implements a rule for DVB-T2. Rules for other
delivery systems can be added in _guess_delsys() in
a similar way.
Additionally: Store list of adapter-supported
delivery systems instead of querying the driver each
time this information is needed.

The URI downloader is creating the source element with
gst_element_factory_make() that returns a floating reference that nobody
is consuming. This is causing problems in WebKit, where the smart
pointers used to take references of the source elment get confused and
end up consuming the floating reference and then releasing the element,
which usually crashes because the URI downloader still tries to use its
src element. See https://bugs.webkit.org/show_bug.cgi?id=144040.
This commit adds two helper functions to ensure and destroy the source
element, to make the code simpler and less error prone. The ensure
method takes care of checking if we can reuse the existing one or we
need to create a new one, taking always its ownership. The destroy
method simply avoids duplicated code to set the source to NULL state and
then unref it.

The gst_adaptive_demux_wait_until() function can be woken up either
by its end_time being reached, or from other threads that want to
interrupt the waiting thread.
If the thread is interrupted, it needs to cancel its async clock callback
by unscheduling the clock callback. However, the callback task might already
have been activated, but is waiting for the mutex to become available. In this
case, the call to unschedule does not stop the callback from executing.
The solution to this second issue is to use a reference counted object that
is decremented by both the gst_adaptive_demux_wait_until() function and the
call to gst_clock_id_wait_async (). In this way, the GstAdaptiveDemuxTimer
object is only deleted when both the gst_adaptive_demux_wait_until() function
and the async callback are finished with the object.

Use the semaphores in the correct place, before and after the submission for
acquiring and presenting the swapchain buffer.
Waiting on the fence that only signals the command buffer completion rather than
the completion of the presentation is racy with the destruction of the vulkan
buffers associated with that image. Wait on the device to be idle instead after
presenting.
Because current GstEGLImageMemory does not inherit GstGLMemory, GLUpload
allocates additional GLMemory and upload the decoded contents from the decoder
which uses EGLImage (e.g. gst-omx in RPi).
This work adds GstGLMemoryEGL to avoid this overhead. Decoders allocate
GstGLMemoryEGL and decode its contents to the EGLImage of GstGLMemoryEGL. And
GLUpload uses this memory without allocation of additional textures and blit
operations.

display from the memory.

Allows creating wrapped memories with GstGLAllocationParams.
The wrapped pointers will be set in the parameters before being passed
to the memory allocation function.
The device name and descriptions returned are in the locale encoding, not
UTF8. Our device name property is in UTF8 though, so we need to convert.
