This way it works (with LD_PRELOAD): $ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so fswebcam - | display - --- Opening /dev/video0... Trying source module v4l2... /dev/video0 opened. No input was specified, using the first. Adjusting resolution from 384x288 to 352x288. --- Capturing frame... Captured frame in 0.00 seconds. --- Processing captured image... Could not find/open font Could not find/open font Writing JPEG image to '-'. Xlib: extension "Generic Event Extension" missing on display ":0.0". Xlib: extension "Generic Event Extension" missing on display ":0.0". $ Can't the program cope with this peculiarity (for an explanation, see, e.g., http://www.altlinux.org/%D0%92%D0%B5%D0%B1%D0%BA%D0%B0%D0%BC%D0%B5%D1%80%D0%B0_%D0%B2_Skype ) on its own? So that the user doesn't have to put the extra LD_PRELOAD stuff into the commandline.
