To play 3gp videos with audio using mplayer in Ubuntu Jaunty, add the following line to your /etc/apt/sources.list file
sudo wget http://www.medibuntu.org/sources.list.d/jaunty.list --output-document=/etc/apt/sources.list.d/medibuntu.list
You need the GPG key for medibuntu packages. Get it the following way.
sudo apt-get update
sudo apt-get install medibuntu-keyring
sudo apt-get update
now install the following packages
w32codecs mplayer mencoder amrnb amrwb
You should be able to hear the sound in mplayer now.
After doing the above, I also had to install the amrwb package, then it worked.
@yochai, thanks have updated the same.
Instructions dont work anymore. I get a 404 on the following URL: http://www.medibuntu.org/sources.list.d/jaunty.list
This is the fitting weblog for anyone who needs to seek out out about this topic. You understand so much its virtually onerous to argue with you (not that I actually would want…HaHa). You definitely put a brand new spin on a subject thats been written about for years. Nice stuff, just nice!
