Available codecs:
   copy     - frame copy, without re-encoding. doesn't work with
filters!
   frameno  - special audio-only file for 3-pass encoding, see DOCS!
   rawrgb   - uncompressed RGB 24bpp video
   divx4    - using divx4linux/divx5linux or xvid (depends on
configuration)
   lavc     - using libavcodec codecs - best quality!
   vfw      - using VfW DLLs, currently only AVID is supported

Now with encoding:
