I'm setting up a live video streaming system with the Niagara 2120 appliance and Wowza 3.1.1. Output from the Niagara is H.264, 30 fps, 750 kbps. The video quality is quite good but very jerky. How can I smooth it out? Dropping the bitrate doesn't seem to help. Are there any settings in Wowza that would help?
