I am running Ubuntu 10.04 with ubuntu-resticted-extra installed. When I play .mkv with the default player, totem it causes the player to stop suddenly without any warning after a random amount of time!

Anybody else is having this problem? Is there any workaround other than installing vlc??

What I want to know is, Is it a bug in gstreamer? or I'm the only one facing this issue!

Try VLC media player. It plays almost every video format flawlessly. – abhishek Nov 14 '11 at 12:20

Its a the meantime...

Install VLC

VLC is a free and open source cross-platform multimedia player and framework that plays most multimedia files as well as DVD, Audio CD, VCD, and various streaming protocols.

enter image description here

Open Synaptic application

Click on System -> Administration -> Synaptic Package Manager. In Settings -> Repositories, make sure you have an universe repository activated.

Search for vlc and install it, as well as vlc-plugin-pulse. You may also want to install mozilla-plugin-vlc.

If you are interested in streaming or transcoding, you should additionnally install libavcodec-extra-52 from a multiverse repository. Command line way

You need to check that a universe mirror is listed in your /etc/apt/sources.list file.

% sudo apt-get update
% sudo apt-get install vlc vlc-plugin-pulse mozilla-plugin-vlc

Install gstreamer-ffmpeg. This should give you better playback with .mkv files. If it does not, then use another player (other than totem), such as VLC, or GNOME-Mplayer.

ubuntu-restricted-extra contains ffmpeg So, it will not help!!! – Vineet Menon Nov 14 '11 at 12:31
@VineetMenon oh my mistake. I did an install for someone recently (but this was 11.10) and I had to install it manually. Try another player. – RolandiXor Nov 14 '11 at 12:33

Try updating your Gstreamer.

Else you can try Mplayer

The above error is happening because there is no libde265 plugin, run the following and it will work. I just did it:

sudo apt-add-repository ppa:strukturag/libde265 
sudo apt-get update 
sudo apt-get install vlc-plugin-libde265
