Thanks Lutz, that is the pointer I needed.
Question: How do we switch the local_alpha? I read in the help
v4l2-ctl that there is this
--set-fbuf=chromakey=<0/1>,global_alpha=<0/1>,local_alpha=<0/1>,
global_inv_alpha=<0/1>,local_inv_alpha=<0/1>
Does this work? What is chromakey? And what is global_inv_alpha and
local_inv_alpha?
