Show episodes jumping around near end of episode

[tyler.of.athenry]

In the last week or so I've noticed Jellyfin jumping around near the ends of lengthy episodes (~45minutes).

I thought clearing transcode cache fixed this after suspecting heavy CPU load led to the issue. However, today I cleared transcode cache and continue to see the same issue in the same spot in the episode.

Could someone guide me towards some steps to take to troubleshoot this?

A few variables perhaps worth considering:

1. Roku app has been updated to the recent new releases
   
2. I've transcoded much of my library to: MP4, HEVC, AAC
   

I am on 10.10.6 and use with Nvidia hardware enabled

I cleared transcode cache and downloaded the episodes to my phone to see if it was the source for our jellyfin. The source file is the issue.

That leads me to either this season is a strange coincidence that multiple episodes are corrupt, or, my tdarr process broke them while converting them to hevc with aac

I've encountered issues where a whole batch of files from the same source were broken.

I only know vaguely how Tdarr works. I know you can use ffmpeg with Tdarr, but I don't know if you can customize what ffmpeg parameters you can use. IF you are using ffmpeg with Tdarr, instead of Handbrake, try adding these parameters to ffmpeg.

Code:

-max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled
