1. Set media.autoplay.allow-muted;false 2. Visit any Gizmodo Family Website. 3. Revoke Permission "Autoplay Media With Sound". 3. Scroll to a Gizmodo video entry. The video plays regardless of the setting.
Matthew, can you triage this?
While trying to repro this, I wasn't served any autoplaying video content when I tried scrolling through gizmodo.com.au's front page until I hit the "end" (page 5 shown in the location bar, a button to load more content appears). Visiting jalopnik.com, I'm shown a video under "Recent Videos" that begins autoplaying only if I scroll it out of view and back into view. If I also toggle media.autoplay.enabled.user-gestures-needed to false, it never starts autoplaying. It seems unexpected that scrolling would be considered a user intention to allow the video to play, but I'm not familiar with the autoplay blocking policy. I'll needinfo Alastor to get his input.

This issue is because we didn't check the pref "media.autoplay.allow-muted" when decide whether video without audio track can autoplay.
Assignee: nobody → alwu
Summary: Jw Player bypasses autoplay permission → Should not allow video-without-audio-track to autoplay when pref "media.autoplay.allow-muted=false"
When talking about autoplay, video without audio track should also be controlled by the pref "media.autoplay.allow-muted".
