1144306 - Video for HTML5 Player for Youtube Cuts to Black

Status: RESOLVED WORKSFORME

(Core :: Audio/Video, defect)

Description

[halosteel1436]

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 20150305021524

Steps to reproduce:

Mozilla/5.0 (Windows NT 6.3; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0

1) Set media.mediasource.enabled to true in about:config if in stable or use Firefox Beta or Nightly.
2) If not activated, activate HTML5 player in Youtube by going to https://www.youtube.com/html5.
3) Play any Youtube video with 1080p or 1080p60 quality or above.



Actual results:

Youtube stream plays fine for about four or five minutes, then video stream cuts out and I'm left only with audio. Reloading the page reloads the video stream; however, it, again, cuts out after about four or five minutes.

Troubleshooting steps I've taken:

-Switched to Firefox Beta (did not fix it even though HTML5 support is implemented)

-Switched to latest Firefox Nightly (did not fix it even though HTML5 support is implemented)

-Disabled hardware acceleration in stable (fixed it, but could not play videos in 60 fps or any videos in 1440p or 4k)

-Disabled Ublock (did not fix it)

-Disabled NoScript (did not fix it)

-Tried Chrome (fixes it, as expected, but I don't want to use Chrome)

UBlock and NoScript are the only blocker add-ons that I have installed by the way.


Expected results:

Youtube video should play normally at selected resolution.

Fixed by enabling media.mediasource.webm.enabled in Firefox Beta. 4k video still does not work properly, but I can live with this for right now.
