Problem watching video files

[deadmeat]

I have a Samsung R540 with a graphic card ATI Radeon Mobility HD serie 5.
I installed Mageia 2 GNOME and the updates as well.
I can't watch video files properly, neither avi/mp4 or youtube videos. The image just seams like it is flickering, the movements are not flowing as they should.
I wanted to install new drivers from the ATI website but Mageia tells me to uninstall previous drivers.

How do I uninstall drivers?
Does anyone had the same problem watching video files?

Please don't install the drivers directly from the vendor, we have those already packaged and integrated in Mageia.
Have a look at https://wiki.mageia.org/en/Setup_the_graphical_server
Also please post the output of

Code: Select all

grep -i driver /var/log/Xorg.0.log

The output came out as this:

It doesn't matter what kind of drivers I install or how many codecs, all the videos just keep playing bad.
The image it's just not flowing, it is like instead of being presented by 25fps is 10fps.

ok this might not help, because cetain linux drivers have poorly implemented hw video support, not suggesting yours does, just some have a problem.

I have issues currently with the hw on my i7 ivybridge with hd4000 giving some video performace problems, ive tried various things, so ill suggest them here.

the video player you are using ie videolanclient or mplayer both have options to change the way they use the hw support.

try changing the default format its using ie opengl or XV for example see if any of them improve the perfornace of playback of a video.

not much help to say this but the best video performance i have expirienced under linux is on nvidia hardware with nvidia drivers.

also there are some options like

Section "Module"
LOAD "extmod"
Load "v4l" # Video for Linux
Load "dbe"
Load "glx"
Load "dri"
Load "dri2"
EndSection

that you can add to you xorg.conf

also stay out of full screen mode, i find this has the most issues, and get better picture quality in a window.

there maybe other options that are better suited to ATI hw.

I dont have any ATI hardware so cant offer any incite there.

Nope, still the same. But thank you for the information.
I find it hard to believe that I am the only one with this problem.
Any solutions?

[doktor5000]

Please also add the information what of the hints you tried out exactly.
Also, are you using desktop effects?

Could this be due to viewing interlaced video without a deinterlace filter?
