The Windows.Graphics.Capture API CreateForMonitor has a bug that was fixed in 20H1 that causes an exception to be thrown when an HMONITOR with a value of 0 is provided. This is a valid input used to request capture of all monitors. To avoid this issue, we can restrict screen capture using WGC to versions of Windows >=20H1. Bug: webrtc:13078 Change-Id: Ia66bf2b2738c29813d41e214fdfc1eb96e0a1312 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/229140 Reviewed-by: Henrik Andreassson <henrika@webrtc.org> Commit-Queue: Austin Orion <auorion@microsoft.com> Cr-Commit-Position: refs/heads/main@{#34878}
