Transcode - Server said to be not powerful enough but CPU not maxed out
I have a mac mini running as a PMS (with local PMS database)
All media files are stored on a NAS on the same network than the mac mini.
From remote, when I want to play a H264/20Mbps movie file, I request for a max 4Mbps bandwidth.
Transcoding session starts as it should.
But soon, I got a message saying that the PMS is not powerful enough to sustain a réal time transcoding session.
But when I look at the mac mini; the CPU is only around 20-30%.
Strange thing: the network accesses at the mac min are about 100Mbps in and 100Mbps out (at the max speed on my LAN).
Strange things: 100Mbps is above the H264/20Mbps bandwidth, which is OK, the PMS is fetching the file to transcode it -> but then what are these 100Mbps going out? Is there a link with the PMS poor performance for transcoding?
