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.
[Matthew Waters]: gst-indent the sources and fix a critical retreiving the egl
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.

Some platforms provide an old version of GLES2/gl2.h and GLES2/gl2ext.h that
will fail when including GLES3/gl3.h due to missing typedef's.
Seen on the RPi.
The only mandatory frontend information for our use case
is its status. Make sure we output what we know instead
of choking at the first error getting SNR, BER or any of
the other informational parameters.
1.Porting the exist deinterlace shader and OpenGL callback
to be compatible with OpenGL ES.
2.Add a our blur vertical shader to gldeinterlace.
3.Add a property named “method” to let user choose which
deinterlace function to use. Default to choose blur vertical
method for better performance.
[Matthew Waters]: fix name of greedyh in method property (was greedhy) and port
to git master.

Adds a new function to mpegts lib to create a iso639 language
descriptor from a language and use it in mpegtsmux to add
a language descriptor to audio streams that have a language set.

This fixes a race where we check if there is a clock, then it get
removed and we endup calling gst_clock_new_single_shot_id() with a NULL
pointer instead of a valid clock and also calling gst_object_unref()
with a NULL pointer later.

Some cameras (IDS) have broken DirectShow drivers which incorrectly fill some
fields in the VIDEOINFOHEADER structure; comparison between suggested and
supported media types in CBaseRenderer should ignore deprecated and/or not
essential fields; additionaly explicitely setting the mediatype for the capture
pin before trying to connect it works around another IDS driver bug, and
should have been already done anyway.

Add include path so that the cmake-generated project
is able to find gstconfig.h
Add /SAFESEH:NO to MSVC linker options so it can link with
gstreamer libraries on Windows.

When the test involves doing a seek, only check for data size after
the seek. The final segment range after seek might be different/smaller
than the threshold for doing the seek and doing the check before
seeking would fail.
Following the Don't Repeat Yourself principle, define macros
for the structures that contain the request and response headers,
so that the name is not repeated in multiple places in multiple files.

Test content protection
Configure 3 content protection sources:
- a uuid scheme/value pair
- a non uuid scheme/value pair (dash recognises only uuid schemes)
- a complex uuid scheme, with trailing spaces and capital letters in scheme uri
Only the uuid scheme should be recognised. We expect to receive 2 content protection events

Test header download error.
Let the adaptive demux download a few bytes, then instruct the

is still being downloaded.
