Why do you want to stream LIVE at 100p? It doesn't make sense. You should always stream LIVE content at 25 or 30 fps, not more. Try setting GoPro to these values.
100 fps is intended for recordings, not live content, where you can creatively make astonishing slow-motions in video editor sofware. Reducing 100p video playback speed to 25p gives 1/4 speed super-slow motion with excellent quality and no stuttering picture. This is the only reason for 100p, you can be creative when you do video editing.
But even for recording, if you know that you will never do slow-motion in video editing later, it's useless to record at 100p because very few devices will be able to play back the file. And it will also be much bigger file, totally useless.
Live stream wouldn't make any use of higher frame rates than 30fps. It would use much more network bandwidth, and only a few clients would be able to play it.
