It's also possible that some drivers change behaviour from one linux version to another.

Re: [PD] problems with pdp_v4l2
ola, your camera have surely more formats than this one, so see what format are there when you send an open message to pdp_v4l2 you can then switch formats with [format #number( and reopen the cam.. all of this is in the help file ciao, sevy xà wrote: 2010/7/22 Mathieu Bouchardma...@artengine.ca: On Thu, 22 Jul 2010, xà wrote: im playing with pdp_v4l2 opening the webcam via open /dev/video0 -activating the cam's led-,... but doesnt show any output at all (black screen in the pdp viewport) pdp_v4l2: unsupported color model: 1431918169 pltfrm Ubuntu Karmic // Pd version 0.42.5-extended-20100108 use this shell command : perl -e 'print pack i, 1431918169; print \n' or ruby -e 'puts [1431918169].pack i' and it tells you : YVYU Tried Mathieu and is YVYU therefore, pdp_v4l2 is trying to tell you that it doesn't support the YVYU codec of your camera. the strange point is that also with pdp_v4l doesnt render the cam, and the same camera with pd extended 0.41 and ubun2.hardy worked fine :S thanx anyway salut x!
