Camera board • Re: External MultiFrame Trigger

External trigger with 500Hz, it is noticeable that <= 60 fps GScam triggers on the first pulse, > 60 fps only on the second pulse, is there an explanation?
For higher fps GScrop had to be modified a bit, I hope this is ok for HermannSW?
As an idea/suggestion, could HermannSW perhaps create a GScrop for external trigger?

jpg works:

Code:

LIBCAMERA_RPI_CONFIG_FILE=/home/RPI/Cam/timeout.yaml rpicam-vid --no-raw --width "$1" --height "$2" --codec mjpeg --segment 1 --frames 7 -n --awbgains 1.5,1.5 --shutter 1000 --gain 1 --o /dev/shm/MultiFrame01-%d.jpg
If possible, please correct/improve the following:
mp4 works poorly, are there still wrong parameter, or can't mp4 do anything with only 9 pulses?

Code:

LIBCAMERA_RPI_CONFIG_FILE=/home/RPI/Cam/timeout.yaml rpicam-vid --no-raw --width "$1" --height "$2" --denoise cdn_off --frames 7 -n --awbgains 1.5,1.5 --shutter 1000 --gain 1 -o /dev/shm/extTrig1.mp4
