Allow fallback to orc subproject if any, and add missing orc version check.
Additionally 'dependencies' keyword is removed from find_library,
because it's invalid keyword for find_library.
Replace legacy usage of DecodeFrame2 API in favour of the
recommended DecodeFrameNoDelay()
This fixes problems with DecodeFrame2() not (currently) returning
all frames in main/high streams with B-frames, and reduces latency -
previously openh264 would not return a decoded frame until the next
call to DecodeFrame2(). DecodeFrameNoDelay() returns them immediately.
If the last frame(s) produce errors, then we need to drop them
or else we spin forever failing to decode a frame and thinking
it'll get better if we wait for more data that's never coming.
The fdkaac decoder supports 6.1 / 7.1 channels with downmixer
since v0.1.4. Old versions can use AAC_PCM_OUTPUT_CHANNELS
instead of AAC_PCM_MAX_OUTPUT_CHANNELS.
Fixes#873
The picture structure in the output parameters from
MFXVideoDECODE_Query is set to MFX_PICSTRUCT_UNKNOWN for some codecs, so
the structure of the corresponding mfx surfaces created for decoding are
unknown. The pipeline will be broken when these surfaces are used as the
input for msdkvpp.
Example pipeline:
gst-launch-1.0 filesrc location=input_vp8.webm ! matroskademux !
msdkvp8dec ! msdkvpp ! fakesink
Error message:
0:00:00.031568911 14259 0x55b79dc684a0 ERROR msdkvpp
gstmsdkvpp.c:728:gst_msdkvpp_transform:<msdkvpp0> MSDK Failed to do VPP

This is a workaround for the above issue
The memory type was used as bitwise enum, but the enum was not
defined in that way.
Nonetheless, most of the usage of the memory type was as mutually
exclusive options, rather than option composition.
This patch refactor how the memory type is defined, so it is kept
the mutual exclusion among options.
This is the equivalent of iceTransportPolicy in the RTCConfiguration
dictionary.
Only two values are implemented:
* all: default behaviour
* relay: only gather relay candidates
The third member of the iceTransportPolicy enum, "public", is
obsolete.
There was a mismatch between the .pc files generated by
autotools and by meson that would lead to meson not detecting
that opengl api is available even though it is. This could
lead to build failures when building -bad with meson against
a -base that was built with autotools. The mismatch has now
been rectified but we will still check the old one for backwards
compatibility.
'channel-mask' field should not be put in caps if channel mask is 0x0
Mapping WASAPI channel mask to GST equivalent was going only over
first nChannels elements of wasapi_to_gst_pos array, translating, for
example, WASAPI's 0x63f to GST's 0x3f instead of 0xc3f.
When 'channel-mask' is specified as NULL, it signifies that there's
need to do downmix or upmix and it makes caps negotiation with
audioconvert element impossible. Just omit it.

When building the msdk plugin even if libmfx is found, unless the
plugin is explicitly enabled we should not error out if msdk
dependencies are not found.
Also give an error message when we don't build the plugin on Windows
because we're not building with MSVC.

When the audio device goes away during playback or capture, we were
going into an infinite loop of AUDCLNT_E_DEVICE_INVALIDATED. Return -1
and post an error message so the ringbuffer thread exits with an error.
0a350c610d broke the build by only
building enum types with meson. It also removed gstsrt.c from the list
of sources, causing the plugin to fail to load.
