I want to convert some of my videos from .wmv to .mp4. Not only that, I want to make the size of my videos shorter.

Can anyone recommend me any software?

(ubuntu 12.4 + ram 1 gb)

I will be really grateful...

  1. Install ffmpeg

    sudo apt-get install ffmpeg
    
  2. Convert files like this

    ffmpeg -i input.wmv -s size output.mp4
    

Following size abbreviations are recognized (from man page)

   -s size
       Set frame size. The format is wxh (avserver default = 160x128, ffmpeg default = same as source).  The following abbreviations are recognized:

Package 'ffmpeg' has no installation candidate ??

Here is solution for it. (I had pasted this solution from link provided above, in order save some time.)

sudo add-apt-repository ppa:mc3man/trusty-media

Also note that with apt-get a sudo apt-get dist-upgrade is needed for initial setup & with some package upgrades
More info: https://launchpad.net/~mc3man/+archive/ubuntu/trusty-media
Press [ENTER] to continue or ctrl-c to cancel adding it


sudo apt-get update
sudo apt-get dist-upgrade

sudo apt-get install ffmpeg

after package get installed

ffmpeg -i input.wmv -c:v libx264 -crf 23 -c:a aac -strict -2 -q:a 100 output.mp4
