The VideoLAN Forums

Things were working fine a few days ago. Now, whenever I try to play any video on my computer, I get the error message:

No suitable decoder module:
VLC does not support the audio or video format "h264".
Unfortunately there is no way for you to fix this.

This is happening even with videos that I have played countless times before. I'm guessing it's not a problem with VLC specifically, because I tried with a couple other video players also, and got a similar message. But since VLC is the player I use (almost exclusively), and since I don't know what might be REALLY causing the problem, I thought I'd ask here first. I'm running Ubuntu 12.04 LTS.

I'm pretty new to Linux, so if you can give me instruction Crayola style, that'd be great.

Thanks!

You probably did break your VLC installation, including your libavcodec one. You need to reinstall.

I did reinstall, but it didn't help.

I also have such problem, But it didn't help me

I suggest you to do:
sudo apt-get install ubuntu-restricted-extras
and try to reset settings, type in terminal:
vlc --reset-config

Let me know if it works, but I'm positive it will.
