Hm. Taking the pix_video-help patch: I can switch from driver 0 to driver 1 by sending a message to pix_video. How do I switch to the V4L2 driver ?
when instantiating the first [pix_video] object, you should see (on the pd-console) a list of available drivers. e.g. here i see: video driver 0: video4linux2 video driver 1: video4linux video driver 2: ieee1394 for linux
if you don't have a line with "video4linux2", then you don't have v4l2 support compiled into your version of Gem.
in this case you have to possibilities, both of them include using libv4l (apt-get install libv4l-dev)
- compile yourself a recent verson of Gem (after installing libv4l); it
should autodetect everything for you
- libv4l also supports a wrapper (read the README of libv4l) to bring
it's functionality to applications compiled without it. just do % export LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so % pd -lib Gem
in the latter case, Gemwill still use v4l1 ("video4linux"), but the wrapper should transparently translate this to v4l2
tell us whether this works.
