Has anyone else seen this problem where image captures will give data of
the right size, but not contain any meaningful information (ie. mostly
0xff's, maybe some 0xfe's or 0xfd's interspersed)?
I'm getting this on occasion, and I can't quite figure out why. There's
no noticeable reason why it starts or stops. It sometimes seems like I
can leave the camera unplugged for a while, then plug it in, then it
will work. Other times, i can switch to another camera, have it work,
then switch back.
I've checked shutter speed and gain settings.
Anyone know where I might even look to fix this problem?
I happen to be using a Sony XCD-X700 camera, running Fedora Core 3...
libdc1394 v1.1.0, libraw1394 v0.10.1. I'm primarily using the
dc1394_dma_single_capture() funtion call. Camera settings are: SVGA-1
uncopressed format, 1024x768 mono, 400M speed, 7.5 framerate.
