nice, this works for pixbuf pictures. but with the kdenlivetitle :no  
overlay
as standalone prodcuer the titleplayer works very well.

does mlt_image_rgb24a, also include (like the name seems to say) the  
alpha channel ?
it seems the alpha will not be set.

or must i copy the alpha channel to an extra buffer and set this then  
to "alpha" as property ?

regards marco
