I recently installed ubuntu 12.04 on my system, and completely installed all the updates on my system. I am having issues with video playback.

I was using default media player to play my videos, but since the maximum volume is very low in the default media player, I switched to VLC to play my videos.

Now, whenever I play any of the videos using VLC, then the screen starts "blinking" after every 3-5 seconds, It is really very annoying.

Thinking that this is a issue with VLC, I installed SM Player and played videos on it but the same problem occurs.

Can anyone tell me how to solve this problem, or increase volume in the default media player ?

In case, it matters, I have a Samsung Laptop, with AMD processor


It's may be problem with your video card. Try booting in Recovery mode.

  • Then, why doesn't this happen, when I use Default media player in ubuntu – Pratik Singhal Feb 17 '14 at 14:57
  • Is your visual effect on? Check it by Preference> Appearence> Visual Effect. If it is on, then select NONE. – opu 웃 Feb 17 '14 at 15:08

It might be related to audio and video encoders/decoders. For audio encoders/decoders: try to update your system with

 sudo add-apt-repository ppa:gstreamer-developers/ppa
 sudo apt-get update
 sudo apt-get upgrade

You can also try another video player

sudo add-apt-repository ppa:exmplayer-dev/exmplayer
sudo apt-get update
sudo apt-get install exmplayer

For video encoders/decoders look for latest ppas Good PPA for ffmpeg
