SOLVED: Server becomes unresponsive when transcoding for my phone

Your system is using the iGPU.

Code:

Stream mapping:
  Stream #0:0 -> #0:0 (hevc (hevc_qsv) -> h264 (h264_qsv))
  Stream #0:1 -> #0:1 (copy)

And the previous ffmpeg logs also indicated this. Any CPU usage may be from audio transcoding (not the case for this last one) or from subtitle burn in.

One thing I did notice is your passing in of a font directory. And the boat load of font attachments in this last video.

Are fonts an issue? Did you enable fallback fonts in Dashboard > Playback?
