I encounter problems when playing H.264 (not tested with others) encoded videos with VLC or others players (tested MPlayer, Totem not playing the video just the sound). I'm sure it's about driver but I don't know how to fix it. I tried to install proprietary drivers from AMD but after rebooting I can't log in (only Terminal). My graphics card is an AMD Radeon HD 8 series. I don't know if it's related, I boot with nomodeset option. Thanks for your help.

for me SMPlayer works the best and it plays h264 flawlessly. Did you install sudo apt-get install ubuntu-restricted-extras? and after installing new driver you need to configure X to use it properly. How to config AMD and this can also come in handy.

you must be missing something or you're doing it wrong pay attention to every step! to do a clean install before you must purge old installation files and only then continue to install new ones after it finished configure X as explained in tutorial and only then to reboot. –  JohnnyEnglish Mar 3 at 15:43
    
I have done it like explained in the tutorial. –  user230137 Mar 3 at 15:45
    
what version of ubuntu are you using? –  JohnnyEnglish Mar 3 at 15:47

well did u pay any attention that driver in ubuntu repo not highly recomended for Saucy? you need to read every single detail to understand how it works best at the beginning there's a warning read it it tells what to do next. –  JohnnyEnglish Mar 3 at 15:50

Thnaks to @JohnnyD I have succeeded to solve my problem by manually installing Catalyst 13.4 (this) and then editing the grub option. Change nomodeset option to acpi_backlight=vendor.

if my answer suits you and it solved your problem you can accept it if you agree so the other users could follow your example :-) –  JohnnyEnglish Mar 3 at 22:05

Have you tried installing the "Ubuntu Restricted Extras" for your particular installation? These will give you a series of popular format codecs and plugins that allow you to play most media formats without issue. I'm not sure what version of Ubuntu you are using but assuming you are on 12.04 LTS you would use the following command:

sudo apt-get install ubuntu-restricted-extras
