[libdc1394-devel] iSight image distortion

[Jonathan P. <jon...@gh...>]

Recently having acquired an iSight as a replacement to a crappy USB 
webcam, I set about writing a simple command line program to capture 
data from it using libdc1394.  At first every thing seemed fine, 
however, I've started getting a duplicate partial image at the bottom, 
scrunching the rest of the image upwards.

Allow me to demonstrate visually:

Images saved by coriander also exhibit this distortion, so I do not 
think it is an error in my code.

I am running Debian testing on this computer, featuring the following 
(all from standard packages):
libdc1394 0.9.5
coriander 1.0.0-pre3
kernel 2.4.25

I have also had some problems with image capturing being a bit finnicky, 
sometimes requiring that I issue iso stop/start commands, un- and re- 
plug the camera, or even rmmod and reload all of my firewire modules.  I 
do not know if perhaps these are both symptoms of a greater problem.

Any help would be appreciated, and if there is any missing information 
that I should have included in the first place, I will happily supply it 
upon request.
