Greetings,

2TB WD Green "DVR" drive.

 

Server

Ubuntu 14.04 LTS

Core-i7 3770k (OC'd to 4.4Ghz)

8GB RAM

64GB SSD (system drive)

2 TB WD Green

3 TB WD Red

3 TB WD Red

4 TB WD Red

 

Gigabit Ethernet network connecting them.

I have been using Emby for a while now on my HTPC.

 

My HTPC case only has room for a couple drives, so all my non-DVR media sits on my server. The Emby Server software has been running on my HTPC, and doing well. However, I have been thinking of moving the Emby Server from my HTPC (Win7), to my server computer (Ubuntu 14.04, where the media is held). I mostly did this to make a more direct path for others in the house, who may be using Emby in the future.

 

Now that I installed the Emby Server software on my server computer, I shut down the Emby Server on the HTPC, and had it connect to my Ubuntu server. The media seemed to play fine, though I found the address in MPC-HC suggested it was being "streamed", instead of playing natively. When I check the system resources on the server (Ubuntu), it appears one core of my CPU is maxed at 100% load. This would also suggest that it was transcoding.

 

Now, as I understand it, files should only be transcoded if the player on the other end can't play the file natively. Well, with MPC-HC as the player (through Emby), that shouldn't be a problem, right? To the best of my knowledge, playback wasn't going through a transcoding process when I ran the Emby Server software on my HTPC.

 

I would like these files to play natively for a couple reasons. First, I want the best quality possible, and transcoding doesn't deliver that. Second, I don't want choppy video if I am transcoding my blu-ray rips in Handbrake (100% load) on my server computer.

 

Any thoughts on why these files are being transcoded instead of playing natively?

Ok. I found out what was happening while reading another post. It had to do with the path substitution. Once I entered a path substitution, it started playing files natively, and the CPU utilization when to virtually nothing.

Just seen that some of my movies are for some reason transcoding and some play direct which are in the same movie folders and paths substitution setup just wondered why this is? cheers

Hi this is just one of them

I'm not really in Kodi and the log when playing the file would be helpful, but it could be the Header Stripping. A lot encoders/Players etc. don't like it, so it was deactivated by default in > 5.1 versions of mkvtoolnix (if I remember right). Check if the movies which transcode all are muxed with Header Stripping. If so, you could try to remux the files with deactivated Header Compression.
