I’m currently running through the example “mjpeg.py”.
I was able to save a 15 or so second mjpeg file and replay it in VLC (after resetting my camera).
If I try to run some modified code (below) so that I can save TWO videos … only the second video frames are “saved”.
Is there a way to have the camera save several short videos in a row without resetting?
I see the example “mjpeg_on_movement.py” seems to change the file names every time the program runs/ detects motion …
What am I missing in my code?
Do I need a ‘temp’ directory?
