47bbc997f8 mfvideosrc: Set timestamp on buffer when it's captured
Capture the timestamp immediately when new frame is arrived,
instead of doing that on ::create() method. There would be
time gap between captured time and outputting time.

4986b0dd34 mfvideosrc: Select common formats if both VideoPreview and VideoRecord are available
Some devices (e.g., Surface Book 2, Surface Pro X) will expose
both MediaStreamType_VideoPreview and MediaStreamType_VideoRecord types
for a logical device. And for some reason, MediaStreamType_VideoPreview
seems to be selected between them while initiailzing device.
But I cannot find any documentation for the decision rule.
To be safe, we will select common formats between them.

479a67c1b7 mfvideosrc: Check framerate for target IMediaFrameFormat selection
Not only resolution and format, but framerate needs to be checked
for proper target IMediaFrameFormat selection.

3fb8caf635 mfvideosrc: Handle I420/IYUV subtypes for UWP cases
Microsoft defines two I420 formats, one is I420, and the other is
IYUV (but both are same, just names are different).
Since both will be converted to GST_VIDEO_FORMAT_I420,
we should check both I420 and IYUV subtypes during
GstVideoFormat to Microsoft's format conversion.

502aea3969 mfvideosrc: Add a new property for ICoreDispatcher setting
Since the commit c29c71ae9d,
device activation method will be called from an internal thread.

A problem is that, CoreApplication::GetCurrentView()
method will return nullptr if it was called from non-UI thread,
and as a result, currently implemented method for accessing ICoreDispatcher
will not work in any case. There seems to be no robust way for
accessing ICoreDispatcher other then setting it by user.

37aeb91d54 mfvideosrc: Don't error out when if we've found supported format
While retrieving supported formats by device, the last return might
not be S_OK in case that it's not supported one by us (e.g., H264, JPEG or so).
But if we've found at least one supported raw video format,
we can keep going on.

12532cc8bb mediafoundation: Use core dispatcher of current view instead of main view
Main view might be hidden depending on application's view tree.
In that case, ICoreApplication object doesn't return get_MainView() method

Note that nothing about this behavior was documented by Microsoft
https://docs.microsoft.com/en-us/uwp/api/windows.applicationmodel.core.coreapplication.mainview

c4cb51c63d mediafoundation: Add support video capture on UWP app
New video capture implementation using WinRT Media APIs for UWP app.
Due to the strict permission policy of UWP, device enumeration and
open should be done via new WinRT APIs and to get permission from users,
it will invoke permission dialog on UI.
Strictly saying, this implementation is not a part of MediaFoundation
but structurally it's very similar to MediaFoundation API.
So we can avoid some code duplication by adding this implementation
into MediaFoundation plugin.

This implementation requires UniversalApiContract version >= 6.0
which is part of Windows 10 version 1803 (Redstone 4)
