Raspberry pi zero 2W MJPG Stream and H264 Capture at the same time

I have been trialling raspistill, raspivid, libcamera, picamera for a while now and have landed on the below code as an example of running an MP4 video capture while offering the ability to see a live stream if required. The code gets split into backend python that captures the MJPG stream and the h264 stream and then the h264 stream gets converted to MP4 via MP4Box (gpac). The front end is a combo of html, php, css etc.

Biggest issue so far was the ability to run the MJPG stream for more than 5 hours without the RPI needing to be rebooted to recover. This was achieved by stop and starting the MJPG picamera stream every hour approximately. That way the MJPG stream would not die a slow death. This particular code sits in my car. I create a /temp in memory so the h264 file is first stored in memory before conversion to MP4 and saving to SDCARD (Try reduce number of writes and increase speed of capture/conversion etc in a different subprocess).

I control LIFX front porch light if car sees movement and you could also upload to onedrive using rclone. I use a fisheye lens on a RPI v2. PHP html code to follow . Apache2 used to access mp4 files remotely and MJPG streamed via inbuilt port on port 8000. only wifi enabled.
