Console log from safari containing the failure

We're observing this issue on the current setups:
MacOS: 13.2.1 Ventura
Safari 16.3, 16.4
It is reproducible every time.

Safari has been given Screen Recording permissions in the System settings.

When we try to share the screen, it fails with this error in the console:
"A MediaStreamTrack ended due to a capture failure"

I tried experimenting with the video constraints while calling getDisplayMedia(). When sending a basic object in as video constraints like below, the screen sharing works perfectly fine.
{
    aspectRatio: 1.777,
    frameRate: 10,
}


However, if we send in video constraints like these, we observe the problem.
{
    "cursor": "always",
    "aspectRatio": 1.77,
    "frameRate": 10,
    "height": 1080,
    "width": 1920
}

{
    cursor: "always",
    frameRate: 10,
    height: 1080,
    idealHeight: 1080,
    idealWidth: 1920,
    maxHeight: 1080,
    maxWidth: 1920,
    width: 1920
}

Changing component to WebRTC as this is an issue with getDisplayMedia

This issue is observed on Safari Version 16.4 (18615.1.26.11.22)

I am not able to reproduce locally.
If getting "A MediaStreamTrack ended due to a capture failure", it probably means the capturing session got an error. Could you send me (youenn@apple.com) a sysdiagnose with the timing where the issue reproduced?
Are you able to reproduce either in latest STP?


Thanks,

We can close this. We're no longer able to reproduce the issue on the later builds of Safari 16.4

Thanks for the report, marking as configuration changed.
