Add a global mutex to exclusive access to shared stream buffers, such
as DMABufs or VASurfaces after a tee:
LIBVA_DRIVER_NAME=iHD \
gst-launch-1.0 v4l2src ! tee name=t t. ! queue ! \
vapostproc skin-tone=9 ! xvimagesink \
t. ! queue ! vapostproc ! xvimagesink

This function will take an array of DMABuf GstMemory and an array of
fd, and create a VASurfaceID with those fds. Later that VASurfaceID is
attached to each DMABuf through GstVaBufferSurface.
In order to free the surface GstVaBufferSurface now have GstVaDisplay
member, and _buffer_surface_unref() were added.

There are, in VPP, surfaces that doesn't support 4:2:2 fourccs but it
supports the chroma. So this patch gives that opportunity to the
driver.
This patch also simplifiies
gst_va_video_surface_format_from_image_format() to just an iterator
for surfaces available formats.

Add a new parameter to _create_surfaces(): a pointer to
VASurfaceAttribExternalBuffers.
If it's defined the memory type is changed to DRM_PRIME, also a new item is
added to the VASurfaceAttrib array with
VASurfaceAttribExternalBufferDescriptor.
Also, the VASurfaceAttrib for pixel format is not mandatory anymore. If fourcc
parameter is 0, is not added in the array, relying on the chroma. This is
useful when creating surfaces for uploading or downloading images.

As waiting for the load to be finished is specific to the WebView, it should be
done from our WPEView, not from the WPEContextThread. This fixes issues where
multiple wpesrc elements are created in sequence. Without this patch the first
view might receive erroneous buffer notifications.
Fixes#1386

Currently for buffer splitting only output duration can be specified.
Allow specifying a buffer size in bytes for splitting.
Consider a use case of the below pipeline
appsrc ! rptL16pay ! capsfilter ! rtpbin ! udpsink
Maintaining MTU for RTP transfer is desirable but in a scenario
where the buffers being pushed to appsrc do not adhere to this,
an audiobuffersplit element placed between appsrc and rtpL16pay
with output buffer size specified considering the MTU can help
mitigate this.
While rtpL16pay already has a MTU setting, in case of where an
incoming buffer has a size close to MTU, for eg. with a MTU of
1280, a buffer of size 1276 bytes would be split into two buffers,
one of 1268 and other of 8 bytes considering RTP header size of
12 bytes. Putting audiobuffersplit between appsrc and rtpL16pay
can take care of this.
While buffer duration could still be used being able to specify
the size in bytes is helpful here.

libnice now supports the concept of end-of-candidate, so use the API
for it. This also means that if you don't do that, the webrtcbin will
never declared the connection as failed.
This requires bumping the dependency to libnice 0.1.16

The width/height from the video meta can be padded width, height. But when
sourcing from padded buffer, we only want to use the valid pixels. This
rectangle is from the crop meta, orther it is deduces from the caps. The width
and height from the caps is save in the parent class, use these instead of the
GstVideoInfo when settting the src rectangle.
This fixes an issue with 1080p video displaying repeated or green at the
padded bottom 8 lines (seen with v4l2codecs).

Note that newly added formats (YUY2, UYVY, and VYUY) are not supported
render target view formats. So such formats can be only input of d3d11convert
or d3d11videosink. Another note is that YUY2 format is a very common
format for hardware en/decoders on Windows.

gst_caps_new_simple gets wrong types for rate and channel which
may lead to a crash.
As 64-bit values for rate, depth, format, channels does not
make much sense and since any other functionality in gstreamer
expects G_TYPE_INT for channels and rate, we should stick to that

This (so-far) Linux- and FreeBSD-only API lets users create file
descriptors purely in memory, without any backing file on the filesystem
and the race condition which could ensue when unlink()ing it.
It also allows seals to be placed on the file, ensuring to every other
process that we won’t be allowed to shrink the contents, potentially
causing a SIGBUS when they try reading it.
This patch is best viewed with the -w option of git log -p.
