I think it's the encoding speed that's causing the problem. Typically, encoding faster than real time would be a good problem to have but in this situation, when I stream this fast, it fills up the streaming platform buffer after some point the streaming platform gets too far behind and cuts the stream.
This is why I would like to limit the speed to something closer to 1x.
