Hi,

I am running into transcoding errors when trying to watch content on devices that require the original content to be transcoded by plex, I am getting errors like this:

Failed to set value ‘vaapi=vaapi:’ for option ‘init\_hw\_device’: I/O error  
[AVHWDeviceContext @ 0x147836efbe80] Failed to initialise VAAPI connection: -1 (unknown libva error).  
Device creation failed: -5.  
Error parsing global options: I/O error  
[FFMPEG] - Failed to initialise VAAPI connection: -1 (unknown libva error).  
Error while processing the decoded data for stream #0:1  
Error while decoding stream #0:1: Invalid data found when processing input

These are all within the same error when trying to watch a movie on plex that needs to be transcoded. There are no subtitles for this movie at all and the player will usually say: Conversion failed. The transcoder exited due to an error.
