Improving Decoding Capability accuracy on Media Capability API
rdar://150685443
https://bugs.webkit.org/show_bug.cgi?id=292468
Reviewed by Jean-Yves Avenard.
The regular streaming media capabilities code path is doing finer grained
checks on things like HDR.
We reuse that code path for WebRTC video decoding media capabilities by first
checking whether the video decoder
is supported by WebRTC and is power efficient.
If so, we make another call to validate that the same video configuration would
be supported for MSE.
We then reuse these results.
The reason we do this two step approach is that, HW support be the same for
WebRTC and regular video streaming.
But SW support may be different (VP8 support for instance).
We update GStreamerRegistryScanner::isRtpPacketizerSupported to add missing
FourCC based codec names (vp08, vp09, avc1....).
