Note that in current state, videomixer will color convert to the output
format before blending. You need to make sure you vieomixer output
format has alpha channel, otherwise you'll loose that information.
Whether that is a bug, maybe, fixing it would mean that videomixer would
do colortransform again at the output, it's probably better to simply
add a converter after, but maybe fail the pipeline ?

p.s. I mean: source* -> videomixer ! videoconvert ! videosink
