webcam server: need to NOT write jpeg files, and bind to a different interface

Question

Motion version 3.2.11.1

I am running Motion on an embedded Linux system - on a wireless router, running OpenWRT. My goal is to create a wireless IP webcam, and also monitor some environmental factors. It's almost working. Motion is working, except for some kinks I need to work out.

So I am using the "live webcam server" configuration values to share the images on port 8081.

I have 2 questions.

1. How do I get motion to NOT write jpeg files to disk? They fill up my tiny "disk" in a few minutes. I have pored over the config values and I can't identify a setting that would disable this. Note my

on_picture_save "rm %f"

in the config file below. That seems like a kludge, and since I implemented it, things don't seem to be working quite right, so I wonder if those files are necessary.

2. The platform I am running on has 3 interfaces: lan, wan, wlan. Motion seems to bind to the lan interface. Is there a way to control which interface it binds to?

Many thanks.
