There are 2 different settings for number of threads used on encoding servers, both in the encoding server (-t option) and in the main encoder gui along with the IP-address.
I'd hope it would be possible to set it only in one place, preferably on the server side. The main encoder could ask how many threads are set up, and act accordingly. The main encoder would only need to know the IP-addresses of the servers. This would also make it possible to change number of threads used on a server on-the-fly without restarting the main encoder.
Is there a limitation on number of servers? If so, how many and why? Couldn't find this in the manual.
