I thought your stream was awesome.
Please let me know if you think the choppiness was related to shosho, that's the one thing it is absolutely critical for me to get as good as possible!
If choppiness is in my app I will replace the rtmp streaming library asap, there are alternative libraries I can drop in quite easily.
I can also make quality configurable, e.g. reduce resolution for better performance of low signal.
Thanks for trying it out!
