ffmpeg mp4 to hls transcode fails on Azure Batch with Windows Server Image

Question

Hi - I started from the sample below showing how to use FFMEG with Batch https://learn.microsoft.com/en-us/azure/batch/tutorial-parallel-dotnet#review-the-code

This works.

I then tried to actually transcode the video from MP4 to HLS using FFMPEG but I cannot get it to work. The video and commands I am using does work in Windows 11, a Windows 11 VM and a 2022 Server VM (all on premise) but I cannot get it to work in Batch. Has anyone tried this, is something missing from the Windows Image that I need to somehow configure?

Note I posted a similar question on Stack Overflow and no response yet so trying here.
