You’ll need to give some more meat to the bone.
How about some context…

Without that I can only guess this is from a Plex Media Server running in a docker container with its respective drives mounted without exec permissions (e.g. /config), therefore Plex is failing to execute the transcoders stored on that drive.

@tom80H its running inside VM - ubuntu; what exact details do you need? I can provide. thanks!

From https://support.plex.tv/articles/115002178853-using-hardware-accelerated-streaming/

Can I use Hardware-Accelerated Streaming inside of a virtual machine?

Hardware-Acceleration Streaming is not currently possible inside of virtual machines, as virtual machine hosts do not expose low-level video hardware to the guest operating system. While some virtual machines expose generic 3D acceleration to the guest OS as a virtual driver, this does not include support for accelerated video decoding or encoding.

but there are errors as:

[Transcode] [FFMPEG] - Could not dynamically load CUDA
ERROR - XML: namespace

these are all related to the HW acceleration? thx

correct; CUDA is the Nvidia hw-acceleration API
