We actually figured out that the main problem is in the virtualization layer. We will sort it out ourselves.
The other problem is that it cannot accept yuvj420p. (We have done the last test with CRTMP, but we would like to use Evostream in real production because of its HLS support). We cannot change the input stream, as the same stream goes directly to country wide broadcasting.
We’re currently using ffmpeg in the middle to solve these problems, but eventually we’d like to use multicast directly with Evostream.
