newb : logitech webcam, 2/3'rds visible

[bitbit]

First post, just getting started with ZM, but i have plans to use it to monitor 3-4 cams around the house. But first i'll learn to walk with my oldish logitech webcam.

For some reason i can only get 320x240 working, it does support 640x480, and it works with other webcam apps in ubuntu.
And when i say 320x240 working, its acutally 320x180 or thereabouts, cause the bottom 1/3rd is blacked out. Is this known behavior? It's all good, i can mess around with it and learn the basics iwth this, but it would be nice with the remaining pixels

I'm going to guess your build is with shared memory instead of mmap. Increase your shared memory by at least double (easily searched). Or there is a resolution or palette issue that you'll have to work through.
