Yesterday, Google has released WebM, the open source, royalty-free video format based on the VP8 codec. Opera Labs has already released a WebM supported version for its Opera Browser.

Here is what you need to get it in Ubuntu:

Open the Terminal.

• Execute the command below to download it:

For 32-bit

wget http://snapshot.opera.com/webm/opera-10.54-21867-webm.i386.linux.tar.bz2

For 64-bit

wget http://snapshot.opera.com/webm/opera-10.54-21867-webm.x86_64.linux.tar.bz2

• Extract using the command:

For 32-bit

tar xjvf opera-10.54-21867-webm.i386.linux.tar.bz2

For 64-bit

tar xjvf opera-10.54-21867-webm.x86_64.linux.tar.bz2

• Close the terminal and go to the extracted folder (opera-10.54-21867-webm.i386.linux).
• Double click on the file called “opera”. In the dialog, choose “Run”.
