Description of problem:
I'm pretty sure my Firefox is distro's vanilla,
youtube and others when I opt for eg, 720p video will freeze but I'd still get audio playing ok
change to 360p and both video and audio is ok
I'm on Dell 6430u
please ask for any more info if needed
Version-Release number of selected component (if applicable):
and rest of the OS updated to 9 of Jul
Steps to Reproduce:
another thing is google-chrome-stable-35.0.1916.153-1.x86_64 plays the same content perfectly fine in all available resolutions
Can you point me to some video where you see the problem? And do you use flash for the video playback?
for me one example was:
but I since went to fedora rawhide (22) - firefox-31.0-2.fc22.x86_64
and the problem does not occur here
yes, adobe plugin, I've tried all other available from popular yum repos and still adobe's did best job of them all
also, with rawhide is see that cpu usage is around 20% while playing 720p, even though

Driver Version 3.0 Mesa 10.3.0-devel
GPU Accelerated Windows 0/9 Basic
Vendor ID Intel Open Source Technology Center
WebGL Renderer Intel Open Source Technology Center -- Mesa DRI Intel(R) Ivybridge Mobile
while on f20 it was ~250%
but, sill no accelerated video?
Try to disable flash plugin (in about:plugins) and use HTML5 video playback. Works for me on Fedora 20 with 720p video.
Anyway, if you use flash plugin it's a bug in flash plugin, not in Firefox. Crome has a new updated flash designed for Chrome only but Firefox has to use the old one.
oh, I see, in rawhide it's html player and not adobe's flash, right?
I don't know, you can use flash plugin on rawhide too. It depends on your configuration.

bugs or makes them obsolete.
