Plex 4k Transcoding with GeForce 1050 Ti

[skinsvpn]

I am having trouble transcoding 4k content with my GeForce 1050 Ti. Plex just hangs at 13% and gives up. I feel like the GPU should be more than capable for multiple transcodes even. The issue does not occur in the Web Stream with quality set to automatic (in which it does transcode to 1080) but when 1080 is selected at any bitrate and with a Roku where there is not automatic option it dies. Is this a bottleneck or some other issue?

 

I have tried Automatic and Make My CPU Hurt Transcoder quality setting. I've tried HDR tone mapping on and off. My transcode directory is set to RAM and 'df -h' in the Plex shell shows 62G available. My dashboard screenshot shows hw transcode too.

 

One thing I noticed during a transcode to 1080 is this error:

[Transcode] Codecs: hardware transcoding: opening hw device failed - probably not supported by this system, error: Generic error in an external library

This error does not appear in the logs if I initialize a 720 transcode but the transcode still fails. 

 

Direct play works fine so it should not be a network problem.
