hi jim,

I don't know what that error message is.

you should get the latest gem from svn and compile with libv4l-devel or libv4l-dev, i don't know how it's called in jaunty.

that seems to be solving many people's problems including my own. there is a bunch of posts about it.

best,

J

For some reason pix_video isn't working for me. I've tried a few different webcams, all of which work in other programs. I'm on a 64 bit Linux Jaunty machine and using

Pd version 0.42.4. GEM: ver: 0.91.3 'tigital'

I keep getting this error in the console when I select a camera using a device message

VDIOCGCHAN: Invalid argument

Any thoughts how to track the problem down and get it working? Thanks,

Jim

buenas you could also get the current gem svn with: svn co https://pd-gem.svn.sourceforge.net/svnroot/pd-gem pd-gem and configure it with: ./configure --with-libv4l2 --with-pd=/pathtopdsources/ don't forget to install libv4l & libv4l-dev then set the driver of pix_video with a driver v4l2 message & it should work without the LD workaround! salutis olsen

Thanks everyone. Yes it looks like I must have been using v4l2. This solved my problem

export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
