Thanks @softvision-raul-bucata for your response. One of our customer has issue in browserstack (https://www.browserstack.com/). They were not able to open it in version 100 and above.

@mohsindlb Since it is a different domain, please advise them to submit a separate report.

One of our customer using browser stack for testing purpose and it is not working on it. As per browser stack they uses the real devices to run the browsers.

@mohsindlb Please refer to the above comment I have made.

@softvision-raul-bucata You did not understand what they said. browserstack is a website which allows developers to test their sites on different browsers in virtual machines. A user tested their site in firefox 116 using browserstack and had this error. Not an error to be reported to browserstack or to do with their site

[mohsindlb]

@liamengland1 Yes, correct the issue happens when testing with browser stack which provides the access to wide range of browsers which runs on real devices.

@mohsindlb Thanks for the updated info. So, if I access the provided URL (https://viewer.millicast.com/?streamId=k9Mwad/multiview&muted=true&play=false&pip=false&cast=false&multisource=true&fullscreen=false) directly in a real Mac device, the stream plays.

If I access it from Browserstack, from any real device (accessing Browserstack via a Windows Machine or a Mac Machine on any real browser) and simulating Firefox's latest version available in Browserstack, the video does not play for the live stream. It plays when simulating Chrome.

This is a bit tricky on the first observations, but I will move the issue and we will see the real cause behind this.

Just a one addition, it only fails on Simulated FIrefox version 100 and above on Mac OS but it works on Simulated Firefox for Windows (in Browser stack)
