GUVCView crashes when changing resolution

After I change the resolution in GUVCView, the application crashes. The logs is here.

As indicated by log 2 GUVCView don't always crash directly after switching resolution, but it did directly after stopping recording video. The application doesn't crash if I don't change it.

GUVCView doesn't record any video (only a picture from when I begin recording), could this be the cause?

Re: GUVCView crashes when changing resolution

I am having the same issue with changing the resolution.  I couldn't find a solution to the problem, BUT, as a work around, you can specify command line arguments to set resolution, input format etc.  This works for me and allows the program to run.

Re: GUVCView crashes when changing resolution

You mean that you change the video resolution while you are already recording video?
