I recently emailed Ken about related issues.
Here are his replies (
italics).
#1. Rather than have the App’s arrow buttons advance to Alerts (in the clip playback view), I’d find it far more useful if the buttons behaved like my cable TV remote. That is, the forward button advances 30 seconds, and the back button goes back 15 seconds. I’d use the slider to get near the frame of interest before using the arrow buttons.
I do like some (cable) TV interfaces as well, and will definitely review that for the next major release.
#2. Does a HTTP command exist to stream video in a browser for a camera starting N milliseconds ago?
I do indeed want to add methods for this ... will be coming before too long.
