Package: libopencv-highgui2.4
Version: 2.4.9.1+dfsg-1
Severity: important

Dear Maintainer,

It appears webcam capture is broken. I tried a PS3 Eye(RGB/YUV)
and a PS2 Eyetoy(JPG). On AMD64 both result in garbage. On another
jessie box, this time i386, both cameras crash.

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
       Trying to use example APIs for webcam capture. I tried
       using C/C++/Python, same results on each.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
       I tried switching from i386 to AMD64. On AMD64 the capture
       runs, but all frames are garbage.

   * What was the outcome of this action?
       AMD64 - video frames contain pixel representation of 
           some sort of linker linkage list? Lines like:
           7f5b7acdc000-7f5b7ace5000 r-xp 00000000 08:21 2235125                    /usr/lib/x86_64-linux-gnu/libXrandr.so.2.2.0

        i386 - crashes on first frame

   * What outcome did you expect instead?
       I expected to see video frames, no crashes.
