My OS is ubuntu, for some reason, i need convert m4v to avi, I can do this on windows, but I do not know how to convert m4v to avi on ubuntu, who can give me a help? ThanksAsked Oct, 22 2010
You should be able to use ffmpeg from the command line to do that. It should be installed by default, if not just use Synaptic (System -> Administration -> Synaptic Package Manager) and just search for ffmpeg to install it.
Try these lines in the terminal (obviously replace test.gif and test.avi with whatever you want):
convert test.gif test%05d.jpg ffmpeg -r 5 -i test%05d.jpg -y -an test.avi
The first line should give you a collection of jpegs (1 for each frame of the gif). The second line actually puts it as an avi. You can edit any of the jpegs before the conversion if you need to edit a frame. The -r 5 is the rate, which you can change as needed.
You could potentially just use the ffmpeg to do the whole coversion in one line (without having to do the jpeg part), but your success may very with that method.
