Bug 193230 – Define page media state flags for display capture.

• Component: WebRTC
• Status: RESOLVED FIXED

[Eric Carlson]

MediaProducer::MediaState, _WKMediaCaptureState, and WKMediaState only have a audio and video capture. Add flags for display capture.

Make it virtual pure might be better, that would ensure that every subclass implements it.

DeviceType also has Application and Browser in addition to Window.
I wonder whether we should not remove these 3 types and use Screen for all of them.

One reason is that 'ScreenCaptureMask' refers to screen + the three other types.
If we need to surface that information in some way, we could surface it outside of deviceType.

Or maybe ScreenCaptureMask, HasInterruptedScreenCaptureDevice et al should be renamed to DisplayCaptureMask.

We could compute type based on deviceType.

Should we assert that deviceType != Unknown.

This could be rewritten to something like:

track.onmute = () => assert_not_reached(...)
await new Promise((resolve) => { track.onmute = resolve; });
await waitForPageStateChange(10, internals.pageMediaState();
// with waitForPageStateChange as an async function

Double line.

I did that at first, but realized that this method really only make sense for capture sources. For example, what "device type" should a canvas capture source return?

I removed Application and Browser. We need Window to differentiate screen and window captured "devices". I changed the enum names from XXXScreenCaptureXXX to XXXDisplayCaptureXXX.

That makes the call to the base class constructor so long it wraps and is difficult to read, so I left it as is.

[Truitt Savell]

It looks like https://trac.webkit.org/changeset/239840/webkit

has caused http/tests/media/media-stream/device-change-event-in-iframe.html
to become a flakey crash on Mac Debug WK2. 

Reproduced with:
run-webkit-tests --root debug-239840 http/tests/media/media-stream/get-user-media-localhost.html --iterations 50 -f --debug

I ran this on r239840 with %100 crash rate on Mojave, on r239839 there are no crashes.

[Thibault Saunier]

This introduced a regression where an assertion happens any time we want to use MediaStream on the GStreamer based ports:
