ctaranto 6 Posted April 6, 2022 Share Posted April 6, 2022 I posted another topic similar to this (https://emby.media/community/index.php?/topic/101366-hw-transcoding-was-working-and-now-its-not/#comment-1063318) but that workaround no longer works well. The CUVID decoder results in a green screen for many movies.

Luke 37096 Posted April 6, 2022 Share Posted April 6, 2022 Hi, the reason why we offer both is for this very reason that on since systems one will work better and on others it could be the opposite. If that weren't the case and one of them consistently worked with all hardware then we wouldn't even provide the choice. Link to comment Share on other sites More sharing options...
ctaranto 6 Posted April 6, 2022 Author Share Posted April 6, 2022 (edited) Thanks, Luke. Is there anything in the logs that indicates why NVDEC isn't working? Library compatibility? Missing libraries? After reading various forums, it seems like _cuvid is not the preferred hardware acceleration (https://forums.developer.nvidia.com/t/ffmpeg-unknown-decoder-h265-cuvid-for-geforce-rtx-2060/128265). I changed from -c:v:0 hevc_cuvid to -c:v:0 hevc_nvdec, but ffmpeg throws an error that hevc_nvdec isn't a valid decoder. But the forum I linked to mentions that the preferred way to turn on nvdec acceleration is to use -hwaccel nvdec (instead of the -c:v:0 hevc parameter). That turned on decoding hardware acceleration, presumably using nvdec. I did this test on the commend line (extracting the call emby makes from the log). How would I change emby's parameter list to use -hwaccel nvdec instead of "-c:v:0 hevc_cuvid" Edited April 6, 2022 by ctaranto Link to comment Share on other sites More sharing options...

ctaranto 6 Posted April 6, 2022 Author Share Posted April 6, 2022 Thanks, H2P. Yes, I meant NVDEC. I edited the post to avoid further confusion. I think it's more than a display name issue. When CUVID is selected, I see "-c:v:0 hevc_cuvid" in the ffmpeg command line. When NVDEC is selected, I see "-c:v:0 hevc". It may be the problem I'm having is that instead of -c:v:0 hevc, it should be "-hwaccel nvdec". Link to comment Share on other sites More sharing options...
Happy2Play 8296 Posted April 6, 2022 Share Posted April 6, 2022 Pretty sure this is the reason HWA NVDEC is not happening. Info Scaling >> False False Ffmpeg does not include 'scale_cuda' ... Info ToneMapping (when possible) >> False False Ffmpeg does not include 'scale_cuda' ... But know there is a lot of changes for this in beta 4.7.

softworkz 3338 Posted April 7, 2022 Share Posted April 7, 2022 @ctaranto The difference between CUVID and NVDEC in ffmpeg is that in case of CUVID, the whole video stream is sent to and processed by the Nvidia Media API and in case of NVDEC, the parsing is done by ffmpeg and only the video frame data is sent to the Nvidia API. The API has formerly been called NVCUVID, now NVDEC, but that CUDA decoding that you read about has gone away long time ago while the name stayed for much longer. The decoding is the same (done by the fixed-function hardware "chips" in either case. Those chips are called NVDEC as well) The whole story is really confusing, because there's the ffmpeg naming, the Nvidia API naming and the Nvidia hardware feature naming - three different things... The green artifacts with HEVC_cuvid are a know issue, that's why HEVC_nvdec is the default. From the log I can't see any error, so I'm no sure what it could be. Could you please retry with NVDEC and then grab the first transcoded segment from transcoding_temp? (a subfolder is created there) You can send it to me via PM.

softworkz 3338 Posted April 18, 2022 Share Posted April 18, 2022 (edited) @ctaranto - Thanks for the test segment. It appears to be fine as far as I can see. Do you have any playback problems when choosing NVDEC? On 4/6/2022 at 2:24 PM, ctaranto said: I would like to understand why the newer decoding isn't working for me. In what way doesn't it work for you? I think I got it now, what you're asking about: The Emby installation package which you are using includes an ffmpeg version which doesn't include all of the features like the version we have in most other Linux packages. As such, it doesn't include the scale_cuda filter: Due to the fact that the input source is 4k and the scaling needs to be done in software, the processing pipeline builder might have decided not to use hw decoding at all, considering the tradeoff between copying video data (encoded + raw) to and back from the hardware just for decoding (as the same copying will be required for encoding again). In case of CUVID, the decision process is a bit different for various reasons, but in either case, the primary concern is not the decoding, but the lack of the scale_cuda and tonemap_cuda filters in the ffmpeg which is included in that installation package. I'm not an expert in that area, but maybe you can try to use one of our official Linux installation packages (e.g. for Debian) instead.

ctaranto 6 Posted April 18, 2022 Author Share Posted April 18, 2022 Thanks for the details, sw. I think that's part of the problem - Emby doesn't think my video card can do all the fun things it's supposed to do. There's no way I could use a Debian distribution on an Arch-based distribution. As an experiment, I replaced the Emby ffmpeg with the latest distribution of ffmpeg available (using symlinks). While it did use the latest ffmpeg, It did not make a difference. I think another part of the reason is that when NVDEC is selected, "-hwaccel nvdec" should be part of the ffmpeg command. Instead, Emby sends "-c:v:0 hevc" which does nothing useful with regards to hardware decoding. Can Emby make a change so when NVDEC is selected, "-hwaccel nvdec" is sent on the command line? Or provide a way to override the default of "-c:v:0 hevc"? Link to comment Share on other sites More sharing options...
ctaranto 6 Posted April 18, 2022 Author Share Posted April 18, 2022 (edited) I went back and tried this again. This time, I copied (not symlink) the manjaro-installed ffmpeg executable (in /usr/bin) to a new one (/usr/bin/ffmpeg-emby). I backed up the original ffmpeg-emby first.

I'll confirm that there aren't any green screens next... Thanks for the help, sw! Update: Appears no green screens with testing on movies that previously would green screen using CUVID! For me, using the latest and greatest ffmpeg from my Linux distribution instead of the emby-supplied ffmpeg has enabled NVDEC support.

softworkz 3338 Posted April 19, 2022 Share Posted April 19, 2022 You need to be aware, though, that this ffmpeg version lacks many of the customizations we have and you will sooner or later run into other issues. Also, it doesn't have CUDA tone mapping and the scale_cuda doesn't support format conversions. Recently, another user reported how he extracted the ffmpeg from our Debian package for use on Arch Linux. This might be a better solution for you.

ctaranto 6 Posted April 19, 2022 Author Share Posted April 19, 2022 (edited) Ah. That's what you meant by using the Debian package. Thanks! I'll give that a shot. Update: That died a quick death. The ffmpeg-emby that is installed by Arch is statically linked (21MB). The ffmpeg installed by the Arch itself is 275KB (dynamically linked). The ffmpeg inside of the Debian X64 package is also dynamically linked (275KB). Unfortunately, that package expects the dependent libraries to be in the "Debian" locations, not the Arch locations. I'm sure even if it could find the libraries, they would be out of sync (Arch is always at the latest; Debian is release-based). ./ffmpeg-emby: symbol lookup error: ./ffmpeg-emby: undefined symbol: avfilter_alloc, version LIBAVFILTER_7 Do any other Linux distributions supply a statically linked ffmpeg (or a link to the post how to better extract the Debian ffmpeg)? UPDATE: See the post below for a link how to get ffmpeg from the Debian package working on Arch Edited April 19, 2022 by ctaranto Link to comment Share on other sites More sharing options...

Essentially, it shouldn't use anything from the OS folders, but all from the lib folder of the package instead. Link to comment Share on other sites More sharing options...
ctaranto 6 Posted April 19, 2022 Author Share Posted April 19, 2022 Thanks again. I just discovered (through reading another thread) the Emby Diagnostic plugin. This will hopefully let me put the Debian ffmpeg (and all libraries) into it's own folder segmented away from the OS libraries, and point emby to that ffmpeg executable.

softworkz 3338 Posted April 19, 2022 Share Posted April 19, 2022 Also look at the emby server startup script. You might need to make some adjustments there to env variables being set. (the purpose of the emby-ffmpeg, emby-ffprobe stubs is only to allow running those for testing from the command line but with the same environment in which the server runs them) Link to comment Share on other sites More sharing options...
ctaranto 6 Posted April 19, 2022 Author Share Posted April 19, 2022 (edited) Thanks again, sw. I found the post you were referring to Following that, I was able to get the debian ffmpeg working with my Arch (Manjaro) emby server. Hardware decoding works and tone-mapping options appeared in the advanced transcoding menu! Edited April 19, 2022 by ctaranto 1 Link to comment Share on other sites More sharing options...

ctaranto 6 Posted August 1, 2022 Author Share Posted August 1, 2022 (edited) I recently updated to 4.7.5 and tried the included stable packages of ffmpeg. Unfortunately, this didn't allow for hardware decoding on Manjaro on my system (fully updated as of today). I then reverted back (using Diagnostic Options / FFmpeg Options) to override ffmpeg, ffprobe, and ffdetect to continue to use the Ubuntu versions. I seems that 4.7.5 isn't honoring those overrides anymore. Here's an excerpt from the transcoding log. Note how the ffmpeg being used is /usr/bin (the default) and not /opt/emby-server/bin like I have set in the Diagnostic Options. Also, when I don't override ffmpeg, I do not see any Tone Mapping options. When I override it, I do see those options. I then edited /etc/conf.d/emby-server to point to the Ubuntu binaries. This did make the transcode log change to show it using those binaries, but it now shows that "superscale_cuda" isn't supported (which it used to be before 4.7). Update: After sleeping on it, I figured I would update the Ubuntu ffmpeg binaries from the 4.7.5 release. Doing this solved the problem.
