Should enumeration of microphones and cameras depend on device-kind-specific exposure checks?

https://github.com/w3c/mediacapture-main/pull/773 split "device information can be exposed" into "camera information can be exposed" and "microphone information can be exposed" and applied the new checks before initializing device-specific information when [creating...

Should top-level transient activation be sufficient for `getDisplayMedia()` on cross-origin iframes with allow="display-capture"?

13

This [came up](https://bugzilla.mozilla.org/show_bug.cgi?id=1704278) when we added the transient activation requirement to Gecko. The data flow affected was "click handler in main document" -> `iframe.contentWindow.postMessage()` -> "`getDisplayMedia()` inside iframe". The gesture...

Actual: Filename and Debug Filename both libexpat.so.1. Version information is still kind of available in the Debug Identifier, but this requires guessing...

A compiler clever enough to know that z is positive with a non-zero biased exponent could, for example, optimize away the scalbnf(z,n) because behavior for left shift of negative values...

The first "audiooutput" `MediaDeviceInfo` returned from `enumerateDevices()` is not the default device when the default device is not exposed

20

https://github.com/w3c/mediacapture-output/issues/113#issue-704418273 proposed output device ordering in enumerateDevices() results to identify the default audio output device. It also said 'This also probably means it should always be exposed since '' allows...

restore default audio output position first in the enumerateDevices() returned list

https://github.com/w3c/mediacapture-main/pull/1057 removed the ability to identify the system default audio output device, and to detect when the system default audio output device changes, from the ordering of audio output device...
