FFmpeg exited with code 1

[Trance Kat]

Hello all.

I recently purchased an HP EliteDesk 800 G3 i5-7500 for the iGPU (my main server is dual Xeon) to use with Jellyfin.

When I attempt to play a file that requires transcoding, I get an error from Jellyfin:
Playback Error
The client isn't compatible with the media and the server isn't sending a compatible media format.

The error in the logs(https://pastebin.com/YCXicTb9):

Code:

[16:52:39] [ERR] [26] Jellyfin.Api.Helpers.TranscodingJobHelper: FFmpeg exited with code 1

[16:52:39] [ERR] [26] Jellyfin.Server.Middleware.ExceptionMiddleware: Error processing request. URL GET /videos/b3fae46f-4530-ca85-782a-d859fc30fc9a/hls1/main/0.ts. 

The file is an HEVC with AAC audio.  The client is a wimpy chromebook.  The file does play directly.  I'm at a loss as to what I can do to fix this.  I am grateful to any help.  Thank you in advance!
