aballim 0 Posted May 7, 2017 Share Posted May 7, 2017 (edited) Hi all I've put emby server onto my new machine for the family. It's got an i7.7700K, 32gb of DDR4-2400, a samsung evo 960 M.2 512gb as the system disk, and a GTX 950 for graphics. Can anyone suggest if I'm better off using QuickSync or NVenc for transcoding? What are the trade offs? Thanks in advance Edited May 7, 2017 by aballim Link to comment Share on other sites More sharing options...
Guest asrequested Posted May 7, 2017 Share Posted May 7, 2017 Quick sync. It's the most supported and that CPU/GPU (I have one) is really good. Is this your HTPC, too, or just the server? Link to comment Share on other sites More sharing options...
aballim 0 Posted May 7, 2017 Author Share Posted May 7, 2017 Just the server. I tried Quick Sync but some of my videos didn't work, so I switched to nvenc and they worked. I'll have to look at the logs to see what happened Link to comment Share on other sites More sharing options...
Swynol 375 Posted May 7, 2017 Share Posted May 7, 2017 defo use quicksync. with NVenc your limited to 2 transcodes. For QuickSync to work do you have a custom FFMPEG? i use zeranoe FFMPEG Link to comment Share on other sites More sharing options...

I'll have to look at the logs to see what happened There may be conflict between the two. The iGPU may not work with the GTX 950, plugged in. You BIOS may be disabling one in favor of the other Edited May 7, 2017 by Doofus Link to comment Share on other sites More sharing options...

Maybe I'll see if I can activate multi screen in bios, and see if that allows quick sync to work. Link to comment Share on other sites More sharing options...
aballim 0 Posted May 7, 2017 Author Share Posted May 7, 2017 OK, activated multi monitor support in bios, and using zeranoe ffmpeg. Still didn't work. Changed the transcoding temporary path from my ramdisk to the C. drive, and lo and behold, success. Link to comment Share on other sites More sharing options...

aballim 0 Posted May 8, 2017 Author Share Posted May 8, 2017 So is there a permissions issue one the Ramdisk? Can't really tell. Maybe it's too small (1 GB).

Well 1GB is barely large enough for a SD tv show. The transcode path has to be larger than the file you are attempting to play. Emby maintains the entire transcode until the media is stopped, and sometimes a little longer. Link to comment Share on other sites More sharing options...

dthurston 0 Posted May 10, 2017 Share Posted May 10, 2017 My server is running on linux on a celeron N2930. I installed ffmpeg, but not the zeranoe version mentioned above. I'm not clear on how to know if quicksync is working, but I assume it's not if it doesn't seem to make much difference. It's not crashing either though. How much load should I expect it to take off the processor during on the fly transcoding? Emby no longer has an option after install for ffmpeg location, so I'm not sure how to change it if I were to install the custom version. Is there a ffmpeg version recommended for emby on linux?

Quicksync isn't really supported on Linux unless you can find a custom kernel. I think the only flavor that supports it is CentOS. So chances are, it's not working, even if you point to an ffmpeg version that supports it. Link to comment Share on other sites More sharing options...
