jhoff80 87 Posted February 19, 2018 Share Posted February 19, 2018 Wouldn't this likely be caused by the same issue mentioned at https://emby.media/community/index.php?/topic/55876-quicksync-apollo-lake-windows-10-not-working-cpu-fallback/page-2 I know it's Apollo Lake vs Coffee Lake, but it would seem to still be a related QuickSync thing.

Luke 37129 Posted February 19, 2018 Share Posted February 19, 2018 Yes quick sync is failing and therefore we are automatically switching to CPU transcoding. We've adjusted our command line params in he beta server so you could try that if you like. Thanks. Link to comment Share on other sites More sharing options...
Ionian 0 Posted February 20, 2018 Share Posted February 20, 2018 Thanks for the replies guys! I tried the latest beta 3.2.70.16 and found a newer version of the graphics drivers ( released by intel about a week ago) and the performance improved slightly. However it is still not what I think it should be. Testing with one of the more demanding files - a 60fps 4k h265 10 bit 50Mbs clip ( http://4kmedia.org/samsung-travel-with-my-pet-hdr-uhd-4k-demo/ ), I am getting the following results when playing from the web player: various transcoding settins: 1) HW: QuickSync - HEVC Decoding: NO - Encoding: NO CPU 70%, GPU 0%, FPS 64 2) HW: QuickSync - HEVC Decoding: YES - Encoding: NO CPU 30%, GPU 60%, FPS 53 3) HW: QuickSync - HEVC Decoding: NO - Encoding: YES CPU 65-70%, GPU 0%, FPS 63 4) HW: QuickSync - HEVC Decoding: YES - Encoding: YES CPU 65-70% , GPU 0%, FPS 63 5) HW: NONE CPU 65-70%, GPU 0%, FPS 63 So, it turns out that the worse transcoding performance was actually the one where it used the GPU As for the ffmpeg command line in the other thread, I'm getting errors when running that against the ffmpeg build bundled with emby.

Luke 37129 Posted March 30, 2018 Share Posted March 30, 2018 The next release of Emby Server for Linux x64 will include NVENC support out of the box so all you need to do is enable it. Nvidia Cuda and OpenCL drivers will need to be installed first. These cannot be freely distributed by us so you will need to refer to your respective distro to learn how to install them. Thanks !

vick1982 15 Posted July 7, 2018 Share Posted July 7, 2018 I run a G4600 under Ubuntu 16.04 with emby and vaapi hw-transcoding. It runs really well. It handles up to 4 simultaneous hevc 10bit 50Mbps movies transcoded to 5mpbs h264. It's probably the cheapest and most future proof media server you can build and also having a really low power consumption. The CPU and a board will probably cost you about 130€ and thats it. what hard drive are you using ? does this cheap cpu have any disadvantages for using as a media server Link to comment Share on other sites More sharing options...
Gerrit507 24 Posted July 7, 2018 Share Posted July 7, 2018 what hard drive are you using ? does this cheap cpu have any disadvantages for using as a media server What kind of disadvantages should it have? It's obviously not thr fastest CPU but because it has the HD630 it's as good as any other Intel CPU in hardware transcoding. I use multiple hard drives in RAID5. When we're talking in dimensions of probably four simultaneous streams it doesn't matter at all what hard drive you have... Use a SSD as the system drive if you can but even this isn't really necessary. 1 Link to comment Share on other sites More sharing options...
adoteq 0 Posted October 27, 2018 Share Posted October 27, 2018 Yeah, well. I have i3-7130u with 4k decoding support for hdr 10 and main10, using VLC media player. However, when I try to use Plex it doesn't work without stuttering and buffering, even on a 4k hdr10 capable Tv from Panasonic. And when I use Emby for 4k transcoding to 1080p Samsung tv, it doesn't work. If I use kodi on local pc it does work. Why? It is kaby lake cpu 2018!!!
