What are you basing that assumption on? VLC supports an insane number of codecs and containers, while webOS supports a very, very small subset and is even highly sensitive to the encoding of MP4 streams being sent to it, so it's somewhat disingenuous to suggest there's a high probability of success just because it works in VLC.

On other platforms, all I have to do is plug in the address and login credentials and the app automatically knows what to do.
Look, if having access to your home webcam is critical, I'd just recommend getting a cheap Android device (or sticking with one if you already have it) and installing "IP Camera Viewer" on it; it knows hundreds of network camera brands and thousands upon thousands of cameras with full pan/tilt/zoom and other camera-specific functionality right out of the gate. It's simply too late in the game for webOS in its current state to get an app of that caliber and comprehensiveness on the platform.
