With the new Emby server release, I see that there are two options for each hardware encoder/decoder now: the existing VA-API one and a new QuickSync one. My Emby Server runs directly in Debian on a Pentium Gold G5420, identified as Coffee Lake (gen9.5). So what's the difference? Which one is preferred, and why? (Technical details welcome.) Is this an "if it ain't broke, don't fix it" case or a "try it and see what works better/faster" deal? TIA

It's been a while Just got Emby working on my 2018 Mac Mini which is more or less dedicated to being a media server. Works well but when someone starts playing a video that needs transcoding the CPU ramps up a ton for about two minutes for FFMPEG to transcode the file and have it ready. This has been the case since I first turned it on, starting with 'Enable Hardware Transcoding' set to 'yes' and no other options touched. I realized that hypothetically I should be able to access whatever QuickSync/T2 based hardware acceleration this thing has via whatever FFMPEG Emby is using, so I checked out 'advanced' and then saw VideoToolbox which I guess acts as a wrapper for any hardware interfaces Apple would expose. I know there have been other threads talking about this, but none of them seem conclusive. Either way, turned it on, then things really started to get interesting. The CRF setting never changed, I've always had it set to 23 (default) but for some reason when VideoToolbox was on the quality of the transcode dropped like a rock! Even in the client trying to tell it to get 60Mbps 1080p still resulted in the same blocky mess. Disappointed with the results I decided to turn the Enable hardware acceleration when available back from advanced to yes and there I started encountering different problems. The Video quality went back to normal but I noticed sometimes in the clients I tried to use (chrome on another computer) the video would never start playing. I'd get a somewhat normal looking log file but I would never see the client playing information in the dashboard and the video would never start! Restarted the computer and things seemed normal. Yet sometimes I'm having a hard time getting transcoded videos to play now using Chrome. I wanna start by addressing the source of my first issue : Is hardware encoding on the Mac Mini ever going to actually be a viable thing or should I give up? I will include two logs which resulted from trying to play one file, the first time with the software AVC encoder and the second with VideoToolbox. There's some weird stuff going on here, without turning VideoToolBox on, the encoder goes through and checks if hardware transcoding is viable: >>>>>> Affected codecs Encoder libx264 Software Encoder Profiles: Baseline Profile (Level 6.2), Main Profile (Level 6.2), High Profile (Level 6.2), High 10 Profile (Level 6.2), High 4:2:2 Profile (Level 6.2), High 4:4:4 Predictive Profile (Level 6.2) >>>>>> FindVideoEncoder - Media: h264, UseHardwareCodecs: True, Mode: Automatic Info Checking: 'libx264 Software Encoder' Info Check successful - selecting 'libx264 Software Encoder' >>>>>> FindVideoDecoder - MediaType: h264, Mode: Automatic Info Checking: 'Automatic software decoder' Info Check successful - selecting 'Automatic software decoder' >>>>>> Processing Plan Info Name CanDoInHardware WillDoInHardware Reason Info Automatic software decoder >> False False Software Codec Info VideoInput >> False False Not a hardware decoder Info SubtitleBurnIn >> False False Info VideoOutput >> False False Not a hardware encoder Info libx264 Software Encoder >> False False Software Codec >>>>>> Projected Processing Formats Info Previous HW-Context Format SW-Format Next Info h264 >> - yuv420p yuv420p >> subtitles Info subtitles >> - yuv420p yuv420p >> It seems to think it can't be done in hardware because it has subtitles. But with VideoToolBox turned on, it somehow makes due: Affected codecs: >>>>>> VideoToolbox H.264 Profiles: Baseline Profile (Level 6.2), Main Profile (Level 6.2), High Profile (Level 6.2), High 10 Profile (Level 6.2), High 4:2:2 Profile (Level 6.2), High 4:4:4 Profile (Level 6.2) >>>>>> FindVideoDecoder - MediaType: h264, Mode: Custom Info FindVideoDecoder - Checking: 'Automatic software decoder' (Priority: 0) Info FindVideoDecoder - Check successful - selecting 'Automatic software decoder' >>>>>> FindVideoEncoder - Media: h264, UseHardwareCodecs: True, Mode: Custom Info FindVideoEncoder - Checking: 'VideoToolbox H.264' (Priority: 100) Info Encoder supports input stream Info FindVideoEncoder - Check successful - selecting 'VideoToolbox H.264' This is the first area of confusion and the first thing I'd like input on. I'll see if I still have difficulty getting playback to start later. Hopefully someone else who has a similar MacMini with the same processor (3.2 GHz Intel Core i7) can help me out.

Hi, i will thank you for this great software it´s amazing. Now i have one little question. Will it be possible to use the GPU for transcoding (like Intel Quicksync) in the Webplayer? I know Mediabrowser Server 3 uses ffmpeg. I test with ffmpeg standalone at it can use quicksync to transcode. How could i turn this on in the MBS 3? It will be greate for all having a smal HTPC mit a CPU that allows this feature. I look forward to your response :-)

Hello, I'm starting Emby as a Service (NSSM) on my NAS and noticed it isn't using hardwaretranscoding since version 4. Starting Emby as normal user (RDP session) it uses hardwaretranscoding with intel quicksync. I guess Emby isn't detecting the hardware, because of no connected display, or something? I attached the hardware detect logfiles. P.S.: Thanks a lot for Emby. I really love it! emby_user_HD.txt emby_service_HD.txt

I cannot get emby to hardware transcode for anything on unraid. I've got everything configured correctly as far as I can tell. Hardware transcoding is working absolutely fine on Plex but emby keeps going to software and doesn't even list quicksync as an option when I go to advanced under transcoding. I've changed my go file, I've added the /dev/dri in the extra parameters. Quicksync is enabled and is being used in plex. Why not emby? Thanks for any help. Log.txt

Hey there, I am really new to this. I bought a J3455 apollo lake board to create my own small media server. The goal is to transcode x265 up to 4k/10bit. Someone over here got it working on his Synology with the same chip: https://forums.plex.tv/discussion/comment/1561297/#Comment_1561297 My problem is that ffmpeg doesnt seem to be able to use hardware acceleration correctly. It always falls back to the standard CPU transcoding. I use these files for testing: http://www.h265files.com/ All files play fine with hardware acceleration in MPC-HD. But transcoding always falls back to the CPU. I am using the latest Emby beta and tried different intel drivers. I attached the transcoding log. The most interesting part seems to be this: Stream mapping: Stream #0:0 -> #0:0 (hevc (hevc_qsv) -> h264 (h264_qsv)) Stream #0:1 -> #0:1 (copy) Press [q] to stop, [?] for help [hevc_qsv @ 0000025bb36044c0] Could not load the requested plugin '15dd936825ad475ea34e35f3f54217a6': specified object was not found (-9) [hevc_qsv @ 0000025bb36044c0] Error loading plugins [hevc_qsv @ 0000025bb36044c0] Error initializing an MFX session Error while decoding stream #0:0: Function not implemented [hevc_qsv @ 0000025bb36044c0] Error initializing the MFX video decoder: invalid video parameters (-15) Error while decoding stream #0:0: Invalid argument frame= 0 fps=0.0 q=0.0 size=N/A time=-577014:32:22.77 bitrate=N/A speed=N/A [hevc_qsv @ 0000025bb36044c0] Error initializing the MFX video decoder: invalid video parameters (-15) Error while decoding stream #0:0: Invalid argument [hevc_qsv @ 0000025bb36044c0] Error initializing the MFX video decoder: invalid video parameters (-15) Error while decoding stream #0:0: Invalid argument [hevc_qsv @ 0000025bb36044c0] Error initializing the MFX video decoder: invalid video parameters (-15) Error while decoding stream #0:0: Invalid argument [hevc_qsv @ 0000025bb36044c0] Error initializing the MFX video decoder: invalid video parameters (-15) Error while decoding stream #0:0: Invalid argument transcodinglog.txt serverlog.txt

Issue: Once I finish playing a movie or a tv show on the roku, the app goes back several minutes and replays a part of the movie/show that we've already seen. Findings: This doesn't happen when "hardware encoding" is turned off but only seems to happen when its turned on. Is there a way to stop this from happening and still leave hardware encoding on or is it out of Emby's control? Reason I ask is because i can leave "hardware encoding" off for mpeg-ts transcoding but for high profile h264 transcoding (due to low bitrates), "hardware encoding" is a must for my mini-pc. One of the moderators, i think @@Happy2Play, said that H264 decoding wasn't actually working due to a bug with ffmpeg but i think that was pre-netcore so i don't know if it still applies post-netcore

I am having some issues getting hardware transcoding to work properly with Emby Server on Centos 7.2.1511. I have successfully installed Media Server Server Studio and build the necessary custom ffmpeg. When I try to play something that should get transcoded I get an error. What is strange is when I run vainfo as seen above, it trys libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so But the emby transcoding logs show it trying libva info: Trying to open /usr/lib64/dri/i965_drv_video.so How do I make emby use the version that shows from vainfo?

I'm running Emby on an old 4 core Lynnfield Xeon processor. It's running as a guest in Proxmox VE, along with several other VMs (OpenMediaVault, Nextcloud, Minecraft, etc). I've been thinking about building a dedicated box just for Emby since I've spread the gospel such that I'm regularly having 2-3 users on at any given time and the poor machine just can't keep up if titles need to be transcoded. I'm thinking a box a separate server would hold the files, so the Emby hardware would just serve/trancode. I've seen folks talk about hardware acceleration and I'm curious how robust it is in Emby. Is there a max number of users that, say, Quicksync can serve? Are other users denied access, or can it serve two users with Quicksync and the rest with CPU transcode? Are there any distributions that have a recent enough version of ffmpeg to work with hardware encoding or am I looking at installing a third-party package or compiling ffmpeg myself? Is anyone using Arch Linux with hardware encoding on Intel or Nvidia hardware? Are there any plans for a Radeon/Ryzen hardware acceleration solution? Does anyone think I would be better off encoding my library to minimize trancoding instead of fitting hardware to the problem I'm facing? Sorry if I'm asking too many questions. Thanks, folks.

Hi Everyone, Quick question...which Hardware Acceleration setting would the community recommend for an Intel HD5500 (Core i7-5500U, Dell XPS 13)? Thanks, hopefully this Topic will help someone else out also! -JBL
