aye the issue is the decoding/extracting frames takes a brutally long time.
each storage drive is:
4 cameras (currently. more to come hopefully)
13 days (roughly)
24/7 recording
means I need to extract 60*60*24*13*4=4,492,800 frames total. then recombine them back into an MP4 @ 30fps. I'm fine with leaving the encoding part as CPU based, as that's usually running about 15fps, and once I have all the extracted frames I can easily batch process that to run. That'd take 83.2 hours, or just about 3.5 days continuous, to process. I'm fine with that part. it's the extracting that takes over a week to do.
Yea I know shinobi does timelapse, but it sucks at 6 seconds per frame, so it's easy to miss things going by the cameras. And I want the 1fps files so I can delete the "useless" footage, as I go through and tag only the time stamps that have interesting things going on in front of the cameras, but still have a useful continuity file if I ever needed this stuff as evidence.
