I’ve been experimenting with the All Sky camera setup to try and extend the total exposure time for an exposure. One limiting factor is the camera firmware which limits exposure to 1 second.
The way that iSpy gets the images from the camera is using a combination of RTSP (Real Time Streaming Protocol). The command line for that is the funny string of characters you entered when first setting up the camera (rtsp://admin:@192.168.1.253:554/mpeg4)
This is then passed into iSpy via FFMPEG software, which is basically a communications interface. Here’s where I’ve made a discovery. I can change the command line to allow frame integration of 2,4 or 16 frames i.e. 2s, 4s, 16s exposure.
I still have a little more playing about to do before I release the command line but it looks promising. The FFMPEG documentation is a nightmare but it’s incredibly powerful
