I’d like to put my Blu Ray collection on the Mycloud EX2.
First, I ripped one of my discs to an ISO image. Then I remuxed the main movie into an mkv file via MakeMKV.
I put the ISO and the mkv on the NAS, and here’s the problem :
- If I play the mkv file on my Win 8.1 laptop, the CPU usage of the NAS is 99% the whole time. To be precise: it’s the samba deamon smbd that’s uses the CPU.
- However, if I mount the ISO image on my Win 8.1 laptop, and then play the iso, streaming is perfectly fine, and the NAS CPU usage is about 3 to 4% or even 0. That is why this cannot be a network bandwidth issue.
MakeMKV doesn’t encode anything, it simply wraps the Matroska container around the transport streams, so the bitrate of the stream is exactly the same in both cases.
So can someone explain the difference between mkv streaming and ISO streaming in regards to cpu usage of the NAS / Samba server?
