52a82f5b84 mftransform: Fix deadlock when MFT requests processing output twice 
This sequence of event/data flow might happen

1) Initially we have one pending output event
  1-1) Then, process the pending output data
2) No pending input event, then we should wait new pending input event
  2-1) Wakeup by new pending event (but it's pending output event)

In above case, MFT will not report new pending input event
if pending output is not processed.

0f74785b8e mfvideoenc: Set PAR to output IMFMediaType 
We've set it to input IMFMediaType but not for output.
So, if PAR is not 1:1, the input IMFMediaType will be accepted
by MFT (default is 1:1).
The PAR of input/output IMFMediaType must be identical

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

cee619486a mediafoundation: Add support for AAC encoding 
Add MediaFoundation AAC encoder element.

Before Windows 10, mono and stereo channels were supported audio channels
configuration by AAC encoder MFT. However, on Windows 10,
5.1 channels support was introduced.

To expose correct range of support format by this element
whatever the OS version is, this element will enumerate
all the supported format by the AAC encoder MFT
and then will configure sink/src templates while plugin init.

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)

eece89042a mediafoundation: Introduce Microsoft Media Foundation plugin 
The Microsoft Media Foundation (MF) is the successor of DirectShow.
This commit includes two kinds of video capture implementation,
one uses IMFSourceReader interface which is available since Windows Vista
and the other is based on IMFCaptureEngine interface which is available
since Windows 8.
Note that this new video source element cannot be used in UWP app
for now, since device activation using those APIs are not allowed by MS.
