How to get thumbnail on Edge?

[Alexandr_Lopatin]

Hello.

Origin-Edge scheme.

I can get image from Origin

http://ORIGIN_IP:8086/thumbnail?application=live&streamname=myStream&size=640x360&fitmode=letterbox

How can I get thumbnail image from Edge? It is possible?

http://EDGE_IP:8086/thumbnail?application=liveedge&streamname=myStream&size=640x360&fitmode=letterbox

Now I get only 404 error (Stream not found).
