1b4c9eaebb va: Fix a typo in video format mapping.
GST_VIDEO_FORMAT_Y412_LE is a 4:4:4 format and so should be mapped
to VA_RT_YUV444_12 rt format.

4ac9f91921 alphadecodebin: Fix stall due to QoS
alphacombine element is a simple element that assumes buffers are always
paired, or at least that missing buffers are signalled with a GAP. The QoS
implementation in the GstVideoDecoder base class allow decoders dropping
frames independently and that could lead to stall in alphacombine.

a8ec40c850 wasapi2: Rewrite plugin and implement audioringbuffer subclass
... based on MediaFoundation work queue API.

By this commit, wasapi2 plugin will make use of pull mode scheduling
with audioringbuffer subclass.
There are several drawbacks of audiosrc/audiosink subclassing
(not audiobasesrc/audiobasesink) for WASAPI API, which are:
* audiosrc/audiosink classes try to set high priority to
  read/write thread via MMCSS (Multimedia Class Scheduler Service)
  but it's not allowed in case of UWP application.
  In order to use MMCSS in UWP, application should use MediaFoundation
  work queue indirectly.
  Since audiosrc/audiosink scheduling model is not compatible with
  MediaFoundation's work queue model, audioringbuffer subclassing
  is required.
* WASAPI capture device might report larger packet size than expected
  (i.e., larger frames we can read than expected frame size per period).
  Meanwhile, in any case, application should drain all packets at that moment.
  In order to handle the case, wasapi/wasapi2 plugins were making use of
  GstAdapter which is obviously sub-optimal because it requires additional
  memory allocation and copy.
  By implementing audioringbuffer subclassing, we can avoid such inefficiency.

In this commit, all the device read/write operations will be moved
to newly implemented wasapi2ringbuffer class and
existing wasapi2client class will take care of device enumeration
and activation parts only.

9e86ac4a22 v4l2codecs: add wrappers for alpha decode
codecalpha is a new plugin introduced to support VP8/VP9 alpha as
defined in the WebM and Matroska specifications. It splits the stream
into two streams, one for the alpha and one for the actual content,
then it decodes them separately with vpxdec and finally combine the
results as A420 or AV12 (i.e. YUV + an extra alpha plane).

The workflow above is setup by means of a bin, gstcodecalphabin.

This patch simulates the same workflow into the v4l2codecs namespace,
thus using the new v4l2 stateless decoders for hardware acceleration.

This is so we can register the new alpha decode elements only if the
hardware produces formats we support, i.e. I420 or NV12 for now.

bfbb49144c va: h265dec: Use get_profile_from_sps() to recognize the profile.
The function of gst_h265_get_profile_from_sps() is better than the
function gst_h265_profile_tier_level_get_profile() when we recognize
the profile of the stream, becaue it considers the compatibility.

It is also used by h265parse to recognize the profile. So it is
better to keep the same behaviour with the parse and other decoders.

3bca4045e5 va: h265dec: Set LastSliceOfPic for multi sliced frames.
VA-API HEVC decoding needs to known which is the last slice of a
picture, but slices are processed sequencially, so we know the
last slice until all the slices are already pushed into the
VABuffer array.

In order to mark the last slice, they are pushed into the
VABuffer array with a delay of one slice: the first slice is
hold, and when the second slice come, the first one is pushed
while holding the second, and so on. Finally, at end_picture(),
the last slice is marked and pushed into the array.

fb8ed9e5d2 d3d11desktopdup: Support desktop switches
Before creating output duplication interface, call SetThreadDesktop()
with HDESK of the current input desktop in case a desktop switch has
occurred.

This allows d3d11desktopdupsrc to capture Windows User Account Control
(UAC) prompts, which appear on a separate secure desktop. Otherwise
IDXGIOutput1::DuplicateOutput() will return E_ACCESSDENIED and the
element won't produce any frames as long as the UAC screen is active.

Note that in order to access secure desktop the application still has to
run at LOCAL_SYSTEM privileges. For GStreamer applications running with
regular user privileges this change has no effect.

aac012ce72 dxgicapture: reinitialize duplication interface on ERROR_ACCESS_LOST
IDXGIOutputDuplication can become invalid for example when there's
desktop switch, resolution change or Windows User Account Control prompt
appears on screen.

When that happens, try to re-create the duplication interface for the
changed output. Note that in the case of UAC prompt this operation will
fail if the GStreamer process doesn't run at LOCAL_SYSTEM privileges. In
such situation the source element won't create any frames as long as the
output is occupied by UAC screen.

In order to enable UAC access to sufficiently privileged GStreamer
processes, call SetThreadDesktop() with the desktop handle that
currently receives user input before creating our output duplication.
