Transcoding much slower then Plex on DS3617xs

April 2, 2019

Hi guys,

I installed Emby last night and finding all the movies and tvshows is really fast! So now I am trying to play an tvshow and that is fast too, but when I want to play a movie that is 4kH265 HDR True HD 7.1, I get a lot of lag with transcoding. My 3617 is only using around 50% of the CPU and still every second I have to wait 2 seconds to play 1 second and so on.

So I have setup Hardware encoding to YES and Advanced and bought an Primier account, but still nothing.

What am I doing wrong?

I don't understand comparisons like this that provide no information. One will always do something different then the other, so it is a matter of know what they are doing differently. I have never used Plex so I have not idea what they are doing differently so are there log files that you can provide? I would guess some differences are the way h265 is converted to h264, as Emby almost doubles the bitrate, or potentially what the client bitrate/quality is set to.

But if this is potentially a HWA issue, then you will need to post the server, hardware_detection, and ffmpeg logs.

How to Report a Problem

Hi there, we're happy to help. Can we please look at an example? Please attach the information requested in how to report a media playback issue. thanks !

I am sorry for not posting an complete message. I am nooby with Emby. It looks promissing!

Here's a video that show piece of the mkv.

Same movie on plex no problems on same machine.

I also setup the transcode to be written on Volume2. That's a RAID0 2x SSD drive and should be very fast

Here's also my log from the server

Can you please try turning off the subtitles? It should perform much better then. Thanks.

April 3, 2019

Hi Luke, thanks for your reply. Tried turning off subs, but same problem

April 15, 2019

That other software is probably converting 4k to 1080p. We are converting 4k to 4k and this is a very intense process.

I would suggest lowering the in-app quality setting to 1080p, and then it should convert faster. Please let us know if this helps. Thanks.

April 16, 2019

Thanks Luke for your reply. I switched to 1080p 8mbps and it looks like this is getting better.

There is an AUTOMATIC option that will switch right? With the other app it will automatically transcode to lower quality when it is stuttering. For some reason Emby does not do this ?

April 18, 2019

This is an area where we can still improve Automatic. Your reason for stuttering is slow transcoding at 4K. Currently the automatic measurement only incorporates network performance into the decision making, not server machine performance. That is something we''ll need to add. Thanks.

Transcoding much slower then Plex on DS3617xs
