Problem Playing .mp4 video

Asked by Tema on 2012-08-24

I am trying to play a .mp4 video that I downloaded off the net in movie player. The video won't play. It just searches for plugins:

• audio/x-gst-fourcc-enca decoder
• video/x-gst-fourcc-encv decoder

In looking on the web, others have had this problem with no fixes available.

I am running Ubuntu 12.04. everything is updated.

Any help is appreciated.

There is a simple way to install a lot of stuff that was not shipped with Ubutunu, due to legal questions and restrictions. The package ubuntu-restricted-extras is a collector for such stuff, if you install it, most of the petented and unfree video codec along with other stuff like Flash will be installed.

You can also run "sudo apt-get install ubuntu-restricted-extras" in the Terminal and see what it wants to install, say No and install only parts of the list.

"Restricted extras" are already loaded, but I will try again.

Here is the terminal:

tema@Amt-work:~$ sudo apt-get install ubuntu-restricted-extras
[sudo] password for tema:

ubuntu-restricted-extras is already the newest version.

todd@Amt-work:~$

The movie still will not play. Thanks for your help.

What kind of file is it exactly? Please run

avconv -i video_filen_ame

and post the output. If avconv is not installed, it is in the package libav-tools.

The video has an unknow codec 0x76636E65, which would translate to "encv".
This are usually DRM protected videos. You can not just load them off the net and play them neither on Windows or Linux.

Can you help with this problem?
