Hello there!

I was trying to run Gem (PDExtended 0.43.4) on Raspberry (running Rasbian 3.6.11 distribution) but it seems that it is not possible opening a gemwin since Gem doesn't support OpenGL ES (Raspberry has ARM architecture)

I just need to get the webcam input (using pix_video), but, if I understood well, to access to webcam I need to create a gemwin first.

Do you know if there is a port of Gem for OpenGL ES? Or if it is possible to access to video data from a webcam without create a gemwin?

Thank you.

Gem hasn't been ported for OpenGL ES (at least not yet). It has been discussed quite some times on the list. If you could run another application to use your camera and stream the data over to Pd...there was a guy on the list who wanted to trigger some videos with a RPi, and he was advised to use Pi's native video player and trigger that with [shell] running scripts.
But I guess that if you want to manipulate the camera input, it won't be possible..

Thank you for your reply!

Yes, I'd like to generate sounds as a function of images taken from the camera and maybe generate some video effects and show them by a video projector. That would be very cool!

I hope to see an OpenGL ES port soon!

Anyway... Could you please provide me the link to the thread you were talking about?

Thanks.

You can find the mailing list archive in Pd's main website. Anyway, this is the link http://www.mail-archive.com/pd-list@iem.at/ just use it's search with keywords and you'll find a few threads on this, I think it was more than one.
