Sure will.
I just wanted some help figuring out whether the problem is in my
driver, or image_view, or opencv. Without much documentation I could
not be sure I was sending the right stuff.
For multi-byte data, how should I set the
`sensor_msgs::Image.is_bigendian` field? I believe the 1394 spec says
the input frame *is* big-endian (high byte followed by low byte).
Could that be causing the crash?
