White screen on displayed video.

I compiled opencv and BosonUSB on a raspberry pi but when I run any of the commands the displayed video in the small window is all white. It shows one instant of the camera then it goes all white. Despite this when I save them with f in a folder the captured images all look fine and I can see what's on the camera. Here is what I see in console.

./BosonUSB fcap
Boson Capture and Record Video tool v1.0
FLIR Systems

use : 'BosonUSB r' to capture in raw-16 bits mode   (default)
Use : 'BosonUSB y' to capture in agc-8  bits mode
Use : 'BosonUSB z' Zoom to 640x512 (only in RAW) mode  (default ZOOM OFF)
Use : 'BosonUSB f<name>' record TIFFS in Folder <NAME>
Use : 'BosonUSB [0..9]'   to open /dev/Video[0..9]  (default 0)
Use : 'BosonUSB s[b,B]'   b=boson320, B=boson640   (default 320)
Press 'q'  to quit

>>> Folder cap selected to record files
>>> Boson_320 selected
>>> /dev/video0 selected
>>> 16 bits capture selected
>>> Image width  =320
>>> Image height =256
>>> Buffer lenght=163840

** (Boson_320 : RAW16  Linear:24535): WARNING **: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files

On another note it works fine on my desktop setup so I am not sure how to debug this. And yet another note I can open the camera in VLC on the same raspberry pi and view the video just fine.

Sorry, no idea of this one. it could be that the linear AGC is failing due to some strange pixel data? Have you tried with 8 bits only? if it works i would say that there is a value that is making the AGC fail in the code... but don't have a reason for that.

Ah sorry for not getting back to this. The issue no longer happens after a reinstall. It was likely an issue with my installation of opencv at the time I'll just close this.
