Ubuntu: Encoding video files


So you have an iPod/Phone or some other poratable media player and you want to encode your huge avi/dvd/mpeg flicks into the formats these devices support.
There are tonnes of easy to use encoders for Windows. For Linux, let us look at some great alternatives...

MEncoder and ffmpeg are the two common encoders. Both of them use the libavcodec and support a decent list of output containers.

To encode DVDs, try AcidRip which is a gtk frontend to MEncoder.

Check out their websites for more instruction on how to go about using them.

Here are some examples using MEncoder
