User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0 Build ID: 20150728030209 Steps to reproduce: 1) Enter the following YouTube video: https://www.youtube.com/watch?v=8uaoBTBofto 2) First second plays fine 3) On the next 4 seconds, the video is freezed (but the audio is OK). 4) Any interaction after that is totally fine Notes: 1) Tested on Nightly with e10s enabled. 2) The video quality seems not to be a factor. Actual results: The video got freezed for 4 seconds at the beginning of the video. Expected results: The video shouldn't have freezed for ~4 seconds at the beginning.
OS: Unspecified → Windows 8.1

When media.mediasource.enabled is true, this bug appears. Set it to false, and no freeze is seen.
Also, if not able to reproduce, try to reload without cache to reliably reproduce it (Ctrl + R).

It's the exact same video, and depending on which resolution displayed is that same as bug 1180935. Seems evidence enough to me
this one is https://www.youtube.com/watch?v=8uaoBTBofto bug 1180935 is https://www.youtube.com/watch?v=q6EoRBvdVPQ It is a 100 percent different.
I was referring to https://bugzilla.mozilla.org/show_bug.cgi?id=1180935#c4
(In reply to Jean-Yves Avenard [:jya] from comment #8) > I was referring to https://bugzilla.mozilla.org/show_bug.cgi?id=1180935#c4 I see. You said bug 1180935 was fixed in bug 1180935 Comment 43. But, I can still reproduce this problem on Latest Nightly(2015-08-02). So, this is a definitely different bug.
This one is very puzzling. I can see the WMF decoder being fed data properly between 0 and 5.8s but it only outputs the two keyframes found at t=1s and t=5.33s everything in between (128 frames) are lost
