I'm running DVA3221 with a Nvidia 1050 Ti graphics card. I'm on DSM 7.2-64570 Update 1. My goal is to have Plex hardware transcoding within docker. Hardware transcoding without docker in the Synology Plex app works. It wasn't easy, but it's working. A piece I was missing was installing the NVIDIA Runtime Library from Package Center. I didn't see that mentioned anywhere in any instructions. My drivers are loaded properly on the NAS: root@nas:/volume1/docker/appdata# nvidia-smi Sat Sep 2 11:26:23 2023 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 440.44 Driver Version: 440.44 CUDA Version: N/A | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.

Confirming by running nvidia-smi from within the docker: root@nas:/volume1/docker/appdata# docker exec plex nvidia-smi Sat Sep 2 11:26:30 2023 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 440.44 Driver Version: 440.44 CUDA Version: N/A | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.

Maybe some of these files don't work on 7.2? However, Plex hardware transcoding does not work. I get the following in my Plex logs: DEBUG - [Req#583/Transcode] Codecs: testing h264_nvenc (encoder) DEBUG - [Req#583/Transcode] Codecs: hardware transcoding: testing API nvenc for device '' () ERROR - [Req#583/Transcode] [FFMPEG] - Cannot load libcuda.so.1 ERROR - [Req#583/Transcode] [FFMPEG] - Could not dynamically load CUDA DEBUG - [Req#583/Transcode] Codecs: hardware transcoding: opening hw device failed - probably not supported by this system, error: Operation not permitted DEBUG - [Req#583/Transcode] Could not create hardware context for h264_nvenc DEBUG - [Req#583/Transcode] Codecs: testing h264 (decoder) with hwdevice vaapi DEBUG - [Req#583/Transcode] Codecs: hardware transcoding: testing API vaapi for device '' () DEBUG - [Req#583/Transcode] Codecs: hardware transcoding: opening hw device failed - probably not supported by this system, error: Generic error in an DEBUG - [Req#583/Transcode] Could not create hardware context for h264 DEBUG - [Req#583/Transcode] Codecs: testing h264 (decoder) with hwdevice nvdec DEBUG - [Req#583/Transcode] Codecs: hardware transcoding: testing API nvdec for device '' () ERROR - [Req#583/Transcode] [FFMPEG] - Cannot load libcuda.so.1 ERROR - [Req#583/Transcode] [FFMPEG] - Could not dynamically load CUDA DEBUG - [Req#583/Transcode] Codecs: hardware transcoding: opening hw device failed - probably not supported by this system, error: Operation not permitted DEBUG - [Req#583/Transcode] Could not create hardware context for h264 Since native Plex works, the following emby-ffmpeg command also works: /volume1/\@appstore/EmbyServer/bin/emby-ffmpeg -i source.mp4 -c:v h264_nvenc -b:v 1000k -c:a copy destination.mp4 Any ideas on what could be wrong? Thanks!
