Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.82 Safari/537.36 Steps to reproduce the problem: 1. タブを2つ開き、それぞれウィンドウを分ける。 2. 一方のウィンドウでchooseDesktopMedia()を実行し、もう一方のChromeタブのウィンドウを選択してスクリーンシェアを開始する。 3. スクリーンシェアを行っているタブのウィンドウを最小化する What is the expected behavior? 他のアプリのウィンドウを選択してスクリーンシェアを行ってターゲットのウィンドウを最小化するとスクリーンシェアが終了(MediaStream endedイベント)するのと同じように、Chromeのウィンドウがターゲットであった場合でも同じように最小化するとスクリーンシェアを終了してほしい。 What went wrong? スクリーンシェアが終了しない(MediaStreamのendedイベント発生しない) Did this work before? N/A Chrome version: 52.0.2743.82 Channel: stable OS Version: 10.0 Flash Version: Shockwave Flash 22.0 r0

niklase: can you find someone in your team to reproduce this? It's for M52 so it's not related to the new UI, but I imagine you know the best person to look at this anyway.

This is known behaviour, the question is whether this is a bug or not. I.e. do you want to tear down your session by minimizing a window, or should it just be paused (sending 1x1 black video)?

[triage] hta: what does the spec say? Should we change the behavior?

The relevant spec is https://w3c.github.io/mediacapture-screen-share/ - this is not quite the same interface as the one we support through our extension-based API. It doesn't specify anything special for minimized windows. Ending the track seems wrong; setting track.muted to true makes sense to me. I suggest you file a bug on the spec to get this clarified. On this particular bug, I would see the most reasonable status to be "working as intended".

Agree with hta, it's also a sensitive thing to change given that apps have been built around existing behavior.

Setting to WontFix since working as intended as per comment #9. gtk2kritto: please file a bug on the spec if you wish to improve it. |
