Now that autotools has been removed generate a meson project template in
gst-project-maker.
There are some differences with the autotools project
1. gstreamer-controller-1.0 is not added to the default dependencies.
2. The '-Wall' option is not set explicitly, meson can handle that.
3. The flags in GST_PLUGIN_LDFLAGS have not been ported to meson as
they are not necessary anymore.
The generated project requires meson 0.53.0 for the 'fs' module. It's up
to the user to remove that part in case compatibility with older
versions of meson is desired.

It was introduced for later use of its enhanced feature over IMFSourceReader
such as taking photo with video preview, audio/video capturing at
the same time, etc. But currently it's not our use case, and it would
be maintenance burden.

Add an element that converts AYUV video frames to a DVB
subpicture stream.
It's fairly simple for now. Later it would be good to support
input via a stream that contains only GstVideoOverlayComposition
meta.
The element searches each input video frame for the largest
sub-region containing non-transparent pixels and encodes that
as a single DVB subpicture region. It can also do palette
reduction of the input frames using code taken from
libimagequant.
There are various FIXME for potential improvements for now, but
it works.

This element uses the Desktop Duplication API to capture the desktop screen at high speed.
It supports Windows 8 or later.
It has the following features compared to other elements:
* Runs faster.
* It works in High DPI environment.
* Draws an accurate mouse cursor.

previous code releases GstBuffer too earlier. so we will see
ERROR default gstmsdkvideomemory.c:77:gst_msdk_video_allocator_get_surface: failed to get surface available
ERROR msdkbufferpool gstmsdkbufferpool.c:270:gst_msdk_buffer_pool_alloc_buffer:<msdkbufferpool0> failed to create new MSDK memory
We need to hold GstBuffer reference for msdk if the surfaced locked by msdk.

If the src_peer_caps are EMPTY (e.g. negotiation failed somewhere), the
assertion inside gst_video_info_from_caps would fail and the whole
pipeline would crash. Check for gst_caps_is_empty before
gst_video_info_from_caps and gracefully fail if it's empty.

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.

Add a new wasapi implementation mainly to support UWP application.
Basically the core logic of this plugin is almost identical to
existing wasapi plugin, but main target is Windows 10 (+ UWP).
Since this plugin uses WinRT APIs, this plugin most likely might not
work Windows 8 or lower.
Compared with existing wasapi plugin, additional features of this plugin are
* Fully compatible with both Windows 10 desktop and UWP application
* Supports automatic stream routing (auto fallback when device was removed)
* Support device level mute/volume control
But some features of existing wasapi plugin are not implemented
in this plugin yet
* Exclusive streaming mode is not supported
* Loopback feature is not implemented
* Cross-compile is not possible with current mingw toolchain
(meaning that MSVC and Windows 10 SDK are required to build this plugin)
