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? Stefan

Hi there, I've had a search through the forums and seen things here and there about the transcoding settings and potential hardware transcoding options to ease the burden on the cpu of a mac running Emby Server but haven't managed to solve my issues unfortunately. I run Emby server on a 2014 Mac Mini (2.6ghz i5, 8gb ram, 1TB HDD one), things are set up well but if I watch any file that needs transcoding the CPU in activity monitor can stay consistently at 275 - 325% all for ffmpeg (I mainly have MKV files but also happens for some pre-processed mp4s from Handbrake). I also have HD Homerun for live tv in Emby and the cpu values seen watching that are usually much lower, around 85% - 95%. Unsurprisingly, occasionally my Mac can be radioactively hot and can only assume that it's not a great idea for me to be running Emby Server and using clients that need transcoding when the CPU can ramp up to ~300%, eg my iphone or android tablet on my commute. Using a Pi + Kodi for my tv, it copes better but I have to remember to power down the Pi as sometimes I've woken up the following day to find my Mac sounding like it's ready for take off, which I assumed was Kodi / Emby Server not killing a service of some sort. I have messed around with the settings a little but it's a bit like monkeys writing Shakespeare, I don't really have much of a clue and unfortunately I've not succeeded in improving anything yet. Checking the advanced settings in the transcoding page in the admin, I have one option in the Hardware Encoders but nothing available in the Hardware Decoders. I'm a novice to the processor / transcoding side things and wondered if I'm stuck with this situation? I've tried to search around but not finding any concrete "ah you just need to do this" or "nope, not a great idea to run it on that". If it's the latter I'm considering an i7 NUC but would obviously be happy if I've missed something and there's solution or setting or something bios / setup wise I can do. I don't however want to burn out the mac as it's useful for managing my phone with iTunes and I also occasionally build iOS apps with it, it's not my main machine but it's my only mac os one. If logs help, just let me know and I can try and get some added.

Hey guys, The upgrade from server 3.6.X.X (I forget exactly which 3.6 version I was on when i upgraded) to 4.0.0.2 went just fine, and the a day or two later I went from that up to 4.0.1.0. However, I've run into a few problems with playback since that upgrade. From what I can tell, all issues seem to revolve around a file being transcoded while playing. I don't know whether the local network vs. external network playback is part of the issue or not, but both times the issues have popped up were when streaming to external locations. #1 - In a 2+-hour movie, there were 3 or 4 times where the playback would simply freeze. No crashing of the app, just frozen video that required getting out of it and restarting to get it playing again. #2 - Subtitles (which are stored in a separate SRT file in the movie directory) were displaying when initially starting the video, but stopped showing and would not be found again after the video freezing, even when getting the video to continue after restarting. #3 - Video jumping back - this has happened a couple times, and I will have logs from the second time. In the latest movie this happened with, it jumped back to a point approximately 30 minutes prior to where the video was playing at the time (e.g., at 1 hour and 30 minutes into the movie, it all-of-a-sudden jumps backwards to the 1-hour playback mark and continues from there). I logged in on the Admin account to try and catch a glimpse of the playback data as this was happening (but unfortunately didn't think to get a screenshot of it at the time), and saw that the "Transcode Buffer" was listing a negative value. Normally, the Transcode Buffer seems to be somewhere between 2 and 3 minutes, but in this case it was showing something like -1:37:00. I grabbed what I could for the full log as well as whatever transcoding logs were tied to that movie's playback and will be PMing them to you later this evening, @@Luke. -Roh

Just trying to verify something here. It is my understanding that Live TV, while being recorded, is recorded to the Transcoding Cache Folder and is later moved to the Recorded TV Library folder. This would imply that I could create a Ramdisk and identify it as the location for the transcoding cache, which has the potential to provide 2 benefits. First, and most important to me, it would reduce the write activity on my expensive m.2 NVME drive, which has a finite number of writes. Second, DDR4 RAM is quicker than even Gen3 X4 NVME storage, so I may perceive a performance improvement as well. I have adequate unused RAM so I don't see creating any new system bottlenecks. Now for my questions: 1. Am I correct about the way the LiveTV recording cache works? 2. If so, is the recording file only moved to the recording folder at the end of the recording process or is it written to that folder at some interval during the recording process? 3. Am I missing anything in my reasoning? Thanks

When transcoding movies, even with hardware acceleration turned on on the server, all of the work load is being put on the CPU for both decoding and encoding. Im pretty new to this and dont have much knowledge about how this works. -More specific specs- Processor: AMD FX-3600 Six-Core Processor GPU: Nvidia GTX-960 4GB Ram: 8.00GB DDR3 It might just be something simple i am missing, but no matter what setting configuration i have set, all of the work is done via cpu. From what i am aware, a GTX-960 should be capable of both decoding and encoding. In a recent ffmpeg log file i noticed this following message, I'm not sure if it helps: [h264_nvenc @ 00000206e4fe00c0] Cannot get the preset configuration: invalid version (15)Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameterssuch as bit_rate, rate, width or heightConversion failed! Attatched are my transcoding options, ffmpeg log while transcoding a 1080p movie, and a hardware detection log. Any help to get my GPU to do something would be greatly appreciated ffmpeg-transcode-2d389333-b984-4ddc-8d5f-468abc80f562_1.txt hardware_detection-63686804671.txt

Greetings. I have had this problem for a little while but given that it still remains after the recent updates I figured it was time to report it. This is presumably a setup issue on my server but I am not sure where to start. Basically transcoding of music (ALAC -> something compatible with chromecast audio) is failing reliably after 36 seconds of playback. Non transcoded files (FLAC) playback fine. Any transcoding for movies seems OK too. Logs attached. ffmpeg-transcode-b08f15c5-36ad-40dc-a6dd-4367b30d81a4_1.txt embyserver.txt

I have some 4K material which is hevc encoded. Now this can't not be directly played on all devices it gets watched on so sometimes it needs to be transcoded. I have transcoding working nicely on my nas, 4K is a bit much though unless I use quality settings that decrease the quality significantly. Rather than having to decrease the quality too much I would rather decrease the resolution of the the material, so reduce it to 1080p instead leaving it on 4K. Even though I have found some settings where I could limit settnigs e.g. did try limitinig the device/user to 1080p with a certain bandwith when playing it the file it still played on 4K so the 1080p setting didn't seem to be enforced. I was testing this using the webbrowser on my PC so hevc will be transcoded but my pc is capabable of the 4K resolution. Not even sure if emby will look at those things. So is it possible to force 4K material when it needs to be transcoded to be also resized to 1080p. If this is already possible how can I realize this? As currently I wasn't able to figure this out.

Hi, I am new to Emby, The server is installed on win10 and works pretty well on the LAN. From outside I connect with the web ui. It works as well. My upload speed is 1mb. My media library is made of flac music. As the music stops frequently I would like the flac to be transcoded to mp3 (256kbs or 128kbs) when I am outside. Any parameter for that or config file I could modify? Thanks

Hi There, I just completed a migration of my Emby Server 4.1.0.1 beta running headless Centos 7.6 from a virtualized Hyper-V (2008 R2) to Bare Metal (Intel Core2 Quad Q9300 with Gigabyte [nvidia] GeForce GTX 1050 and SSD) for the added horsepower of dedicated CPU access and transcoding capabilities. I haven't done a whole lot to this OS in terms of setup. Clean minimal install of operating system update updated packages (yum) Install Emby Open Firewall Port install backup plugin restore backup from my VM What I'm struggling to determine is a) has emby detected my GTX 1050? is emby using my GTX 1050 to transcode? c) is there anything I might need to install (e.g. Nvidia drivers) to get this all working? I'm not 100% certain what it is I'm looking for in the logs to ascertain whether this is working or not. I'm attaching the latest Transcoding log and Hardware Detection Log. Thanks in advance HardwareDetection.txt Transcoding.txt

I just discovered Emby App on my new LG B8 TV. So, I downloaded 4.0.1.0 Emby Server and installed the pkg on my OMV Debian server (4.17) running on HP Micro server N40L (low perf CPU). Very easy. Added a handful of movies to a test library (again easy to do). Emby app on the TV shows the added movies. When I select one movie, I can see the default audio (TrueHD) and default subtitle English SRT (embedded in the .mkv). When I play it, I noticed that the Emby server dashboard is showing "Direct streaming" but also transcoding and the server load is around 36%. No subtitles are displayed. I re-rip the movie and make the subtitle an external SRT file and call it ?????.eng.default.srt. Then select it in the Emby App, it plays the movie with the subtitles and importantly, there's no transcoding taking place. The question is, why is the server (or the App) asking for transcoding to be done for embedded subtitles ?

Assuming that m4b is the same format as m4a, it should be played without forced transcoding, even if there is a need for transcoding then -a copy should be used instead of force reincoding to higher bitrate. Please also note flags passed to ffmpeg "-strict experimental -ab 384000" are not accurate, as ffmpeg does not require -strict experimental any longer (aac is quite stable) and bitrate is hardcoded as orginal bitrate was lower, thus probably should be just omited. P.S. Attached the file m4b-transcoding.txt

I use Emby Theatre for Windows every day on main MediaPC in front room, but the last 5-6 weeks I have noticed stuttering and hanging in Emby Theatre. I finally found by looking at the server Dashboard its transcoding every episode I watch even ones watch previously ok. I have done some testing and found if I use the same Media PC Chrome browser and use the Web UI to watch the exact same episode Emby them Direct Streams the episode without stuttering. I also have a Samsung TV (LT32E390S) in the bedrooms with Emby App and this also plays the same episode no issue, but also transcodes. I can understand or work out why this issue has become so come with Emby Theatre recently. Its only become a frustrating issue the last 5-6 wks appx. Any advice, help, steps to help me track the issue?

I was wondering if it might make better sense to change the transcoding speed shown on the dashboard to make it more "useful" Right now when I see it showing a transcoding speed of 28 FPS, I then need to know if this a 23.9 FPS video and the server is keeping up great, or is this a 30+ FPS video and the server is no longer keeping up, and while you can tell to some extent by the transcoder buffer bar if the server has started other task (even not related to Emby) you may be to a point where you will run out of transcoder buffer. I had 2 thoughts on alternatives. 1: Show the videos Actual FPS next to the transcoding FPS so you can see if transcoding is exceeding it. Seems simplest IMO. or 2: Show the transcoding speed in % or multiplier. I.e. Video FPS is 30, Transcoding is happening at 45, show 150% or 1.5x

ok - so upgrading my emby server from a hard working unlocked amd to a new mobo/memory et al need some advice go i5 with a gpu or i7 with lots of memory currently running emby as a docker on rockstor so i'm thinking the i7 with more threads is going to do a better job - that's as long as emby and rockstor can take advantage of the extra threads espeacially when it comes to managing multiple streams - maybe transcoding and as a file server as well any thoughts? @

I recently downloaded Emby (love the software) and its great. Works just like I expected to stream mkv anime files. Everything worked perfectly for about a week and then not so much. All of my media players, Roku, Opera (on computer), Firefox (on computer), Chrome (on computer), and my DLNA Smart Tv does not work. Specifically whenever I try to play a file on the Roku (the roku 3) it tries to transcode then just hangs (the green bar loading bar disappears). I cannot access the DLNA via my Smart Tv. Whenver I try to play via any of my browsers I get the "no compatible streams" message for every one (pictures attached). The only device I own that seems to work is my Galaxy Note 5 through the Emby app. It works perfectly through there. As I test I converted an anime file (one specifically is 10bit down to 8bit) and that works no problem. But it still makes no sense because the other files worked just fine when I first installed Emby. Basically, I need to figure out if I need to convert all my files or if there is another issue on the server I am not aware of. Not sure if I gave enough information but I also attached the logs for server and transcode. Hopefully this helps.

Hi, I've been using Emby for a while on Shield TV and it works fine. Now I have got a LG TV and noticed a lot of issues. Most (maybe all) 4K videos need transcoding when using subtitles on the LG TV (something that doesn't happen in the Shield TV with the same videos and subtitles, I confirmed it). Knowing this I removed the subtitles from the MKV file and dowloaded a SRT subtitle file. Well, that works without transcoding in Emby for LG TV but it doesn't pay attention to line breaks within a subtitle entry, so the result is a mess. Tried the same Movie and SRT file again in Emby for the Shield TV (Android) and the line breaks work fine. I have seen a lot of people complaining about the transcoding in LG TV for these subtitled videos, but no real answers. All in all, it works just fine on Shield TV, so it's clearly an issue with the LG TV port. Any possibility of a bug fix?

Hello, I was wondering how emby works with audio. I was thinking of remuxing some files with 6+ channels, to include a 2 channel track, for users who don't have surround sound. Would Emby detect this track and, use it for those users, or would I have to have a separate file just for 2 channel audio, to avoid transcoding?

Hi, My Emby linux server 3.5.3.0 fails to transcode audio wav files to flac.

(the basics are working) My dlna speaker device supports flac therefor I like to preserve the audio quality as much as possible. If I look at the transcode log file I notice that in the ffmpeg command the extension (.flac) is missing in the output definition. I am no expert on this but it might be related to my issue.

Hi Guys and Gals I'm looking into Emby at the moment, I have bought a premium month to test it out. I do very much like the speed of the UI, and the design of it is mostly good. The recognizing of I have a few issues with HW transcoding. Does it work at all? The NAS I'm running it on is a TS-853A, it uses an Intel® Celeron® quad-core 1.6GHz. I can see that it's recommended to use VAApi, but I don't see any help CPU wise in that, it goes straight to 100% CPU utilization when just doing playback. This makes it unusable for me, as the NAS has quite a few other jobs (Virtualization Station) that is quite important. Being a newbie in Emby, I'm not sure where to get any information for you to help me out.

Video transcoding is checked in the settings, and Blu-ray video is automatically cancelled. Is it a system problem or a deliberate design?In fact, my body will not be able to achieve the specific function of this transcoding.

Right now, every time I use Live Tv to watch something, it shows it is transcoding on the dashboard, but no indication if this is being done in hardware or not. Any way to tell easily?

My Emby server works fine, but often I have buffering issues where it takes forever for a movie to load, and sometimes it doesnt even load at all. I just see the circle wait symbol keep spinning. A lot of my movies are 1080p, but I change the transcoding to 720p with 4MB/s. It improved the playback and loading speed somewhat, but sometimes the movie just doesnt load at all. Standard definition tends to load and play much better. Skipping to certain time points in a movie almost always causes the Emby client crash, and I have to restart the box. Im looking into options to improve my setup, and identify where the bottleneck is. I run my Emby server on Ubuntu 18.04 on an Intel NUC with i5 processor, 8gb RAM. The box is connected to my WIFI router via ethernet cord. My movies are stored on a 4GB portable SSD external hard-drive (connected via USB 3.0). I always set my CPU freq to Performance (2.7ghz). My Emby client is on an X96 android box connected to my TV via HDMI. The box connects to my WIFI via the wifi 2.4 ghz. My WIFI has 5ghz option, but my android box does not. If I was to replace anything, I'd get a new box with 5GHz wifi option to increase the bandwidth as I think this is the bottleneck culprit, although, I do sometimes get the same buffering issues when playing from my web browser on my laptop, which is connected by ethernet cord to the router, so the wireless transmission may not be the only issue. But for the time being, are there options in in the transcoding that I can utilize to speed up to the data transfer? - My NUC box has Intel Iris Plus Graphics 640. What hardware acceleration options would I have? - Would increasing Transcoding thread count help? - Would changing the H.264 encoding preset help? - Are there any options on my Android client that I can tinker with to increase loading speed and fix buffering issues?

I get the following error when transcoding: Unknown encoder 'ac3' How would I go around adding this encoder(and any others that may be missing, that I haven't found out about)? Full log: https://gist.github.com/CtrlAltDefeat94/c19a1f36fe2653ddb11e491ca748f7df
