Originally intended to be an experiment with no future, it turned out to be very popular with streamers that move a lot. In the end it was popular enough that NVIDIA added their own variant to their Broadcast software, which works decently enough. Unfortunately my wrapper code around the library was written very poorly, so it didn't take long for it to break out of nowhere.
