I have the rtsp firmware on my V2 and the video stream displays nicely on my desktop with VLC. But, It’s my understanding that this is like a fork in the road when it comes to mainstream firmware upgrades. ie, I can only flash future firmware updates (if any ever comes) that are specific to rtsp. Curiously, would flashing with the current regular firmware brick the camera or put it back on the path for mainstream upgrades while losing the rtsp capability ?
How can the normal (official) firmware be re-installed once you have the RTSP beta?
Yes. See this page.
