Attached is the clean patchfile. I want to give some small background:
the problem happens in javacpp. It looks like there is a problem
handling pixelformats not correct at all when used for pixel grabbing.
This is why I mentioned it in a streaming context.
However this patch is a small workaround to this and really minimal. We
will look more deeply into the wrapper to get rid of it but in the
meantime....
Thanks
Thomas
