Terminate seek_viewer command #79

Hi, I have a question about the seek_viewer command,I'm trying to use it to record a video through such a command seek_viewer --camtype=seekpro --colormap=11 --mode=file --output=seek.avi,but I ran into a problem that I can't limit the duration of the video without my intervention,for you have to press ctrl+c to stop recording.I want to find out if there is a setting responsible for the duration of video recording without human intervention.
