Re: [GEM-dev] 0.90 and pix_video under Linux

I discovered that if I transform [pix_video] with [pix_grey] , alpha-blending works. [pix_rgba] doesn't.

Hi IOhannes,

Thanks for your reply, but I'm not having any luck.

Alpha blending doesn't work with pix_video using [alpha] and [colorRGB]in the renderchain (it worked in 0.888-cvs).Should I use [pix_alpha] instead ?

hmm. i just tried and it certainly works for me. does it produce any result (e.g.: image dimming but no transparency) ?

Nothing but black.

do you - by chance - have the render order mixed up somehow ?

there's only one gemhead without arguments. I've tried sending messages like function or auto, but only sending a zero to the first inlet of alpha i get the image.

Thanks again
