1238748 - Youtube videos will un-mute automatically after approximately 1 minute

Status: RESOLVED WONTFIX

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

Description

[Martin Shuman [:Marty]]

Attachment: logcat_youtube-mute.txt

Description:
If the user mutes a youtube video, the player will automatically un-mute after approximately 1 minute.

This issue does not appear to be related to the screen timeout, because it still occurred after only 1 minute, after I had increased the screen timeout to 2 minutes.

The time also does not appear to be exactly 1 minute, as I have once seen it occur after only 56 seconds, so the time may not always be exactly the same.

Repro Steps:
1) Update a Aries to 20160111111358
2) Open the Browser app and navigate to YouTube.com
3) Select a video that is at least 2-3 minutes long.
4) Begin playing the video, then mute the video.
5) Wait for the video to finish.

Actual:
After approximately 1 minute, the video will un-mute itself, and audio will begin playing again.

Expected:
The video remains mute and silent for the entire duration of the video.

This is a bad end user experience so nominating this as a blocker.

Bug 1172264 seems to have caused this issue.

Bobby can you take a look at this?  This seems to have been caused by the changes for bug 1172264.  Also ni? on Alison to get this on her radar.

Thanks for let me aware of this issue.

Comment 6

[Jean-Yves Avenard [:jya]]

don't see how this could have anything to do with the media stack. muting being handled by youtube JS.

Especially the commit in question.

I have my doubt that it's a gecko issue
