Hello,

I just installed Ubuntu 9.04, pd-ext 0.41.4 on my new Toshiba Qosmio
F50-138 (GeForce 9700M GTS) and all works fine except the webcam with GEM.
So i decided to download sources and compiled GEM with libv4l as describe at
http://www.mail-archive.com/pd-list@iem.at/msg26631.html
I have (./configure) :

Result:
  Target                 : Gem.pd_linux
  Objects                : Base Controls Geos Manips Nongeos Particles
Pixes openGL

Configuration:
  Compiler               : g++
  CXXFLAGS               : -g -O2 -fPIC -freg-struct-return -O3
-falign-loops=32 -falign-functions=32 -falign-jumps=32 -funroll-loops
-ffast-math -mmmx
			 : -I/usr/include/lqt -I/usr/include/lqt   -I/usr/include/FTGL
-I/usr/include/freetype2
  INCLUDES               :  -I/usr/include/FTGL -I/usr/include/freetype2
  DEFINES		 :

  LIBS                   : -lmpeg3 -ljpeg -ltiff -lGLU -lGL -lXext -lXext
-lX11 -ldl -lz -lm   -lpthread
			 : -lftgl   -L/usr/lib -lquicktime -lpthread -lm -lz -ldl -lquicktime
-lpthread -lm -lz -ldl
  LDFLAGS		 : -shared -Wl,-export-dynamic
			 :

  Strip			 : strip --strip-unneeded

  Install path           : /usr/local

 pure-data:
  version                : 0.41
  extension              : pd_linux

 used optional libraries:

  font-rendering         : FTGL

  image-support
    use ImageMagick      : no
    use TIFF             : yes
    use JPEG             : yes
  video-support
    use mpeg             : no
    use mpeg-3           : yes
    use QuickTime        : yes
    use aviplay          : no
    use ffmpeg           : no
  input-support
    use v4l              : yes
    use ieee1394         : no

GEM works fine after that, but [pix_video] still not work, i get in the Pd
console :
video driver 0: video4linux

So nothing about video4linux2 :(
What can i do ?
Thanx.

To finish, with the terminal and 'gstreamer-properties', the webcam works
fine with v4l2 and 'Chicony USB 2.0 Camera'
++
