Plex Media Server Logs_2025-02-25_19-05-04.zip (2.4 MB)
I recently changed my setup to allow hardware transcode for streaming my media. The transcode HW works fine and is enabled when necessary but sometimes it blocks in “Buffering” for ever. Looking at the log, I can see something like:
[Req#31886d/Transcode] Preparing driver rsv for GPU AMD Phoenix1 [Req#318896/Transcode/vaqxdf3yzi3dpja4gtudj5iz] Preparing driver rsv for GPU AMD Phoenix1
And some time after indefinitely:
[Req#319053/Transcode/vaqxdf3yzi3dpja4gtudj5iz] Timed out waiting for segment.
My setup:
- Minisforum UM790 Pro with AMD Ryzen™ 9 7940HS Processeur and AMD Ryzen™ 9 7940HS and Proxmox Virtual Environment 8.3.4
- Media accessible through a NFS mount on a Freenas server available locally
- Plex installed as lxc on the Minisforum using the Helper-Scripts here
- /transcode folder is tmpfs from Proxmox host with 10G available
The media info where it fails:
- Stream: Transcode (Speed: between 10.9 and 12.1 from what I checked)
- Container: Converting (MKV MP4)
- Video: Transcode (HEVC (HW) 1080p → H264 (HW) 1080p)
- Audio: Transcode (English - EAC3 5.1 → AAC Stereo)
- Subtitle: None
What I tried so far (but the error remains):
- Increase the
Transcoder default throttle bufferto 2700 from what I read in other forums - Remove the subtitles as I read that it is managed by the CPU that could be slower
- Check the transcode tmpfs folder usage when it’s buffering to ensure there is enough size (output I got is:
tmpfs 10G 1.6G 8.5G 16% /transcode)
I hope I gave enough context so that someone could help me or share similar issue and workaround.
Sincerely,
Quentin
