1905841 - screen sharing events don't fire when windows close

Status: RESOLVED DUPLICATE of bug 1615282

(Core :: WebRTC: Audio/Video, defect)

Description

[bkafle25]

Steps to reproduce:

When using the MediaStream API to capture a screen recording in Firefox, it's challenging to detect when the selected window for screen sharing is closed.
I have used the following code :
screenRecordingStream.value =
await navigator.mediaDevices.getDisplayMedia(
displayMediaOptions
);
screenRecordingStream.value.getTracks().forEach((track) => {
track.addEventListener('ended', () => {

});
track.addEventListener('inactive', () => {
 
    
 
});
track.addEventListener('inactive', () => {
    console.log('Track inactive');
    // ...
});
track.addEventListener('mute', () => {
    console.log('Track muted');
});
track.addEventListener('unmute', () => {
    console.log('Track unmuted');
});
track.addEventListener('overconstrained', () => {
    console.log('Track overconstrained');
});
track.addEventListener('readyStateChange', () => {
    console.log('Track ready state changed');
});

});

Actual results:

The MediaStreamTrack object provides several events, such as ended and inactive, but these events are not fired when the user closes the selected window.

Expected results:

It should have trigger some sort of an event to detect when the selected window for screen sharing has been closed.

Jib, can you comment on Firefox behavior related to windows being closed?
