I compile today the svn version of ffmpeg, mlt, mlt++ and kdenlive .. with the documentation of the wiki.
I don't see particular error and kdenlive seems to run very well ... but the video speed effect is not present ..(it was in the 0.5 from repository of Gutsy)
The list available is:
flou par pixellisation
niveaux de gris
I use very often this video effect so it's a problem for me ...
If you have any idea ...
