intermittent Crashing when capturing footage.

[Chris]

Hi everyone,
I'm currently using guvcview 2.0.6 I was hoping to get some help as I'm getting intermittent crashes when capturing video.
For context I work in a Neuroscience motion vision lab and were using guvcview to capture footage from a PlayStation camera running at 100 fps while running a stimulation in Matlab, for automation sake I'm opening guvcview using a bash command that doesn't open a terminal window, as Matlab pauses if it opens a terminal. I'm then sending a kill signal USR1 to guvcview to start and stop the recording based on specific timings in the stimulus, this signal is sent by Matlab once again using a bash command. The crashes don't happen all the time, but once they do start happening they happen multiple times and then seemingly stop for another indeterminate amount of time. Due to the way I have to open guvcview I'm not able to get any terminal logs or even any crash logs in /var/crash. I've tried changing many different video codec settings etc, but none of these seem to make a difference.

If anyone has any advice for debugging this issue it would be greatly appreciate.

I have the same problem, guvcview crashes Xserver whether I'm recording or not.
