 Replying to [comment:2 richardpl]:

 cb(X,Y) will work like that. This is clearly explained in documentation.

 after geq.

 Yes, but I was having the same problem '''even when using
 "format=yuva444p"'''.
 Looks like it's a problem just in FFplay... I checked that FFmpeg really
 works fine

 {{{
 ffplay -i file.mp4 -vf "format=yuva444p,
 geq=lum_expr=cb(X\,Y)+cr(X\,Y):cb_expr=0:cr_expr=0"
 }}}

 Could you please check again with the above command?
