Flash video slow in Chromium

Hi,

I just upgraded from an ancient Ubuntu installation to Arch on my Asus eee 1015PEM laptop. Since the upgrade, Flash videos (on, say, YouTube) are unwatchable; audio is fine, but video displays at ~1 FPS. Can you guys help me watch YouTube again on my laptop?

$ lspci | grep VGA

Hardware acceleration seems to work fine.

$ glxinfo | grep "direct rendering"
direct rendering: Yes

I'm using Chromium, and I have PepperFlash installed.

$ aura -Cs chromium
chromium-31.0.1650.63-1-x86_64.pkg.tar.xz
chromium-pepper-flash-12.0.0.41-1-x86_64.pkg.tar.xz

PepperFlash is enabled (otherwise I don't think I would be able to watch YouTube videos at all).

$ cat /etc/chromium/default 
# Default settings for chromium. This file is sourced by /usr/bin/chromium

# Options to pass to chromium
CHROMIUM_FLAGS=" --ppapi-flash-path=/usr/lib/PepperFlash/libpepflashplayer.so --ppapi-flash-version=12.0.0.41"

The option for enabling this does not appear in chrome://plugins , however.

This is the driver I am using.

$ aura -Cs xf86-video-intel
xf86-video-intel-2.21.15-1-x86_64.pkg.tar.xz

I did play a bit with chrome://flags/ , but only after realizing YouTube videos didn't play in a satisfactory way. Now chrome://gpu/ says everything is hardware accelerated.

I have no issue with blue or green tint.

Am I missing drivers or other packages?

Thanks in advance,
Willard.

Re: Flash video slow in Chromium

Have you tried e.g. firefox or some other browser that doesn't use the pepper variant of flash?

I just did a

$ sudo aura -S firefox flashplugin

and flash videos seem to run fine in Firefox, even when watching videos from ted.com (my Chromium didn't render the video stream from ted.com as well as it did a YouTube video stream).

Is ditching Chromium the solution?

Re: Flash video slow in Chromium

I wouldn't call it a solution, but if it's a viable workaround ...

BTW, I hope you're familiar with pacman and makepkg, not just aura :-)

Re: Flash video slow in Chromium

This is total guess, but since hardware acceleration is assumed with pepper-flash, do you have libva-intel-driver installed?

Indeed.

Re: Flash video slow in Chromium

hi there,

I've just read http://www.omgubuntu.co.uk/2014/01/chro … april-2014

we could test, vote, help pepperflash in aur more and more for mainlaining the package, that's all I think.
