Comment (by cehoyos):

 Lagarith performance can be tested with MPlayer and -vo gl (-vo null
 crashes currently):
 The dll in http://samples.ffmpeg.org/V-codecs/lagarith/ is 10% faster for
 lagarith.avi (RGB) but much slower than FFmpeg for lagarith422.avi (even
 if I do the conversion from yuv422p to rgb that lagarith seems to do
 internally). It is possible that the dll is outdated, I don't know how to
 find out.
 For a better test, a longer and larger RGB sample would be needed.
