MediaCoder is a batch transcoder, which means it enables you to convert multiple files simultaneously. It supports all the major formats, and you can use it either to convert files from one format to another, or to resample files – for example, by reducing a video clips quality to make it phone-friendly. It is distributed under a GPL license which puts together loads of audio/video codecs and tools from the opensource community into an all-in-one solution.

Convert to and from many audio and video compression formats and re-multiplex into various container formats, on the fly, in batch

  • Give you the control over the transcoding process and all the parameters of the transcoded files, so you can learn about, compare among and play with various codecs
  • Specific user interfaces for specific devices with device plug-ins and extensions
  • Fully standalone, no dependent on any media player, filter or codec, no registration of any components into system

It’s easy to use, and you can exampnd it with plug-ins thta enable you to convert files for particular devices, such as the PSP. The only downside is that the whole process can take some time. There is a WIKI with loads of HOWTO’s to help the process.
