Server Version#: 1.30.1.6562 Player Version#: Plex for tvOS 8.13 (4532) Having an interesting issue with hw transcoding and I can only seem to replicate the issue with 1080p files. Whenever I try to transcode a 1080p movie from it’s original quality to a lower quality the CPU is used to transcode the movie not the GPU. The file is MKV H.264 I have been able to replicate the issue on both Linux (Pop OS) and Windows 10 Also tried different hardware and the result is the same The players I have tested this on are Web UI, Plex for Mac, Apple TV Curious to know if anyone else can replicate, seems like a recent issue haven’t noticed it in the past Server Specs: CPU: Intel 10980XE GPU: Nvidia RTX A4500 Second Machine Specs: CPU: AMD Ryzen 5800X GPU: Nvidia 3060Ti ---

Need DEBUG logs to know what’s happening (capture the start of a playback which fails). Download the Logs from PMS Attach the ZIP I suspect the Nvidia drivers being used is the issue. ---

Sorry was just capturing the logs, i have attached them. If I’m reading the transcoder logs correctly Plex does request hw accelerated transcode. [Plex Media [Server Logs\_2023-01-19\_12-49-25.zip|attachment]](https://support.plex.tv/articles/200250417-plex-media-server-log-files/) ---

Did you change the tag from Server-Linux to Server-Windows? Asking because I now see Server-Windows and you’ve shared Windows [PMS logs.](https://support.plex.tv/articles/200250417-plex-media-server-log-files/) Unfortunately, I’m the Linux guy and can’t help. I can however get one of the Windows folks to come help. I do see where PMS isn’t finding a GPU. I don’t know how this is resolved on Windows ( I have a bare windows VM for the most rudimentary tasks ) ```auto Jan 19, 2023 06:07:28.303 [17340] DEBUG - [Universal] Using local file path instead of URL: \\?\Z:\TVShows\Ancient Apocalypse\Ancient.Apocalypse.S01.1080p.NF.WEB-DL.DDP5.1.x264.DUAL-alfaHD\Ancient.Apocalypse.S01E03.Sirius.Rising.1080p.NF.WEB-DL.DDP5.1.x264.DUAL-alfaHD\Ancient.Apocalypse.S01E03.Sirius.Rising.1080p.NF.WEB-DL.DDP5.1.x264.DUAL-alfaHD.mkv Jan 19, 2023 06:07:28.303 [17340] DEBUG - TPU: hardware transcoding: final decoder: , final encoder: Jan 19, 2023 06:07:28.304 [17340] VERBOSE - Sufficient disk space: 347.36MB source file, 232.25GB capacity, 177.02GB available on "C:\Users\Luke\AppData\Local\Plex Media Server\Cache\Transcode\Sessions" Jan 19, 2023 06:07:28.304 [17340] DEBUG - [JobRunner] Job running: set "FFMPEG_EXTERNAL_LIBS=\\\\?\\C\:\\Users\\Luke\\AppData\\Local\\Plex\ Media\ Server\\Codecs\\acf6c67-4446-windows-x86_64\\" & set "X_PLEX_TOKEN=xxxxxxxxxxxxxxxxxxxx477f-a041-f02eff3c2e51" & "C:\Program Files\Plex\Plex Media Server\Plex Transcoder.exe" -codec:2 eac3_mf -analyzeduration 20000000 -probesize 20000000 -i "\\?\Z:\TVShows\Ancient Apocalypse\Ancient.Apocalypse.S01.1080p.NF.WEB-DL.DDP5.1.x264.DUAL-alfaHD\Ancient.Apocalypse.S01E03.Sirius.Rising.1080p.NF.WEB-DL.DDP5.1.x264.DUAL-alfaHD\Ancient.Apocalypse.S01E03.Sirius.Rising.1080p.NF.WEB-DL.DDP5.1.x264.DUAL-alfaHD.mkv" -filter_complex "[0:2] aresample=async=1:ochl='5.1':rematrix_maxval=0.000000dB:osr=48000[0]" -map [0] -metadata:s:0 language=eng -codec:0 flac -b:0 4096k -f flac -map_metadata -1 -map_chapters -1 -t 944.27200000000005 "C:\Users\Luke\AppData\Local\Plex Media Server\Cache\Transcode\Detection\f89229af-b322-4ceb-98df-e983004250ee" -y -nostats -loglevel quiet -loglevel_plex error -progressurl http://127.0.0.1:32400/video/:/transcode/session/1e04c53d-c769-4ee8-90f8-02da54a53801/3a51d2a7-f886-422b-b10f-33d025f29c81/progress Jan 19, 2023 06:07:28.304 [17340] DEBUG - [JobRunner] In directory: "C:\Users\Luke\AppData\Local\Plex Media Server\Cache\Transcode\Sessions\plex-transcode-1e04c53d-c769-4ee8-90f8-02da54a53801-3a51d2a7-f886-422b-b10f-33d025f29c81" Jan 19, 2023 06:07:28.307 [17340] DEBUG - [JobRunner] Jobs: Starting child process with pid 15024 ``` ---

I put both tags as I was able to replicate the issue on linux as well, but I have since deleted that OS and moved to windows to see if the issue was the same, but if its possible could you please get one of the windows guys to take a look Will update tags as well It is interesting that PMS can’t see a GPU, and its only for this video resolution, if I were to transcode to 720p there wouldn’t be an issue ---

Alright didn’t know pop wasn’t supported, will switch to Ubuntu and see what happens, and is quick sync a must? if so looks like I will be upgrading 🙂 ---

If you want hardware transcoding, you need SOMETHING with hardware support. 1. Quick Sync Video -or- 2. A supported Nvidia GPU with you having installed the Nvidia drivers. If you have a Nvidia card, confirm the OS can see it. ```auto echo /sys/module/nvidia/drivers/pci:nvidia/*:*:*.* ``` tell me what it says ---

This is returned: /sys/module/nvidia/drivers/pci:nvidia/0000:68:00.0 PMS picks up the GPU if I transcode to 720p ---

If you’re repartitioning ? 1. Make a ‘/’ partition (128 GB or so) 2. Make a /home to put PMS on 3. Now you’re OS independent 🕶 ---
