Do you know what your bitrate was? I checked stats on my iPhone, and I'm also getting 1920x1080 @ 60 FPS, but the bitrate is under 5000. Assuming the same on my streaming devices, that might be why I notice some artifacts when watching on a bigger television.
Earlier today I was trying to create a Keyboard Maestro macro that would detect when Chrome Capture crashes and automatically restart it. I didn't know how to monitor for a crash, so I fell back to trying to run a check a couple times a day to see if it was running, and, if not, start it. I tried with this AppleScript in my macro, but it didn't detect whether the process was running:
tell application "System Events"
count of (processes where name = "chrome-capture-for-channels-macos-arm64")
end tell
That was followed by a "if count is 0" qualifier. But even when Chrome Capture was already running, it was trying to launch it again. So I gave up at that point.
(I haven't actually had any crashes yet, but wanted something in place in case it happens)
