While trying to make this site available to more parallel viewers i have configured it to work over bunny-cdn.
Its not nessesary to make complicated changes. Only make pull-zones in bunny for the AVideo-Parts like YPTStorage, Mainsite, Live-Plugin,... and change the AVideo-Config to use the CDN-URL's instead of the original once.
For the live-part i have changed the nginx-config a little bit to make the .ts-files cacheable (in the original-config the cache is off for /live/*
