Creality Ender 3 V3 KE: Obico issues running ffmpeg due to need for Bash?

[Jeppedy]

Ender 3 V3 KE with Klipper/Mainsail

I'm new to Klipper, but not Linux and not computers.
I'm still getting used to the slightly constrained linux environment on the Creality Klipper instance.
I've used the Creaity Helper script to install Obico for Moonraker.
I can't get the web cam to work in Obico, but the rest of the app works fine, as do other apps such as Mainsail, OctoApp and others which can all see the web cam.

Obico Moonraker logs report the following, attached.

To be clear: run.sh is there. But it won't run due to the Bash issues and perhaps other concerns.
Trying to get run.sh to run, the first problem was clearly that there was no bash.

I installed bash via Opkg.
Then, Bash is not in the place the shebang line expects it.
I can't run the run.sh by hand, so someting is wrong, and at this point, I'm headed down a rabbit how.

Any suggestions? My relevant log entries below:

I'd love to hear from anyone running a Creality KE with third-party web cam who got Obico working with that camera. If I am the only one it doesn't work for, I will keep trying!

I spoke with the Obico folks. FFMPEG is a no-go on Creality. But, that said, you can still use Obico for spaghetti detection. On my Creality Ender 3 V3 KE with generic webcam, I had to update the snapshot URL to get it working though.
