Choppy video in Firefox with Flash Player
 
Hi,
I've been watching videos online, and every now and then the video will start to get choppy. It will play a bit, freeze for less than a second, then resume, only to have it happen again. I've Googled this, and it says to disable hardware acceleration through Firefox and the flash player. I disabled it on Firefox, and there isn't much improvement. I tried to disable it through the flash player according to Adobe's instructions. I right-click on the Flash Player logo, and I see the "Settings" option they refer to, but it is greyed out and I can't click on it. I went to Youtube, and the "Settings" option is avalible there, so I clicked on it. It opened the settings box in the middle (like it is suppossed to) but it is completely locked up and the flash player became completely unresponsive.

Is there a global config file that I could manually edit to disable hardware acceleration?

Thanks!

post all of your graphics card details in

lspci -v

you can change both applications in FF and options in system settings

webm is far better.

Here's the output. I ran it as root because when I didn't it had a few "Access Denied" messages.

I probably should mention that I'm running Arch Linux, and everything's up-to-date.

Thanks!

I think I figured it out, with the help of this Arch Wiki page: https://wiki.archlinux.org/index.php...ear-free_video (should have looked there first...)

EDIT: Unfortunately, after a few videos, the problem resumed. I went back to the videos where I had no problems, and it was choppy there, too. So it is universal, not just on some videos. Any ideas?

maples 06-12-2014 06:48 PM
It seems like the proper video driver is loaded for my laptop (from the lspci output above).

Here are the intel-related packages I have installed:
Code:
[anthony@newerLaptop ~]$ pacman -Ss | grep installed | grep intel
extra/intel-dri 10.2.1-1 [installed]
extra/intel-tbb 4.2_20140122-1 [installed]
extra/xf86-video-intel 2.99.911-2 (xorg-drivers xorg) [installed]
I have no idea why it worked for 3 or 4 videos just fine, then started being choppy again. Closing and re-opening Firefox doesn't seem to work.

I have one video-related config file in /etc/X11/xorg.conf.d/
Code:
[anthony@newerLaptop ~]$ cat /etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"

#  Tried this next line, didn't work
#  Option      "AccelMethod"  "uxa"

  Option      "TearFree"    "true"
EndSection
Is there anything else useful that I should post? I've never had an issue like this before, so I'm not positive what I need to post.

Thanks!

I thought I'd post what I did, in case anyone has the same issue. I never got Firefox to work, but for whatever reason Google Chrome has no problems at all. So that's what I use when I need to watch a video.
