Vector Preview broken

[emjas92]

Turning on vector_preview = 1 breaks rpicam (for me at least).

After enabling Vector Preview in the web interface, it shows the error "Error in RaspiMJPEG: Restart RaspiMJPEG or the whole RPi"
Restarting does not fix it.
Turning off vector preview in the web interface does not work (remains turned on) - I have to edit uconfig and do start.sh

Here's the log.

This has been happening for a while now, though I don't remember when it started - perhaps it was when I switched from Rasbian to DietPi.
I have tried a fresh install of DietPi + RCWI.
I will try out older verions of RCWI to see if it works in a previous release.

I have just checked latest version of RCWI with Raspbian Bullseye and vector preview works for me.

I have not tried with DietPi. Note that with Bullseye one has to use the leggacy camera support. I don't know what happens with DietPi.

Thanks for checking.

I have a RPi3 and RPi1 both with DietPi Bullseye, and both have the vector preview issue.
But it's strange that all other RCWI functionality is working, including saving the vectors to the .dat file.

I'm currently troubleshooting my motion detection settings and would be using the vector preview, but am working with the .dat file for now.

Broken here too:

• Normal functioning camera stream.
• I set Motion Vector Preview to on, and the stream becomes a tiny mask-sized image that displays white motion-vector specks. The image is so small its not practical for determining where the mask needs adjustment.
• The on/off selector now shows off, despite vectors being on. Selecting off does nothing. Selecting on re-initializes the motion vectors and contracts the previously expanded Motion Settings panel, the selector remains 'Off'.
• Aside from a reboot; I know of no way to restore the normal camera stream.
• [edit] Correction, I know of one way: stop and restart the camera using the GUI button, or presumably FIFO.
• Video recorded by motion detection during this time are normal, except their preview image seems to display what looks like the motion vector preview, or maybe just a very low exposure gain moment as the camera switches.

Hardware pi zero W (not 2W - although I'll test those too if i remember to)
