Emby crashes NAS when casting to chromecast

[2lach]

Ffmpeg transcoding process spikes CPU which results in the crash(es)

Expected Behavior

I should be able to stream mp4 videos to my chromecast from emby with the app.

Current Behavior

After the most recent emby update my NAS (open media vault) crashes whenever i use Emby. This occurs because of CPU overload. The reason behind this is ffmpeg transcodes the video. Last week i could stream mp4 videos from emby to chromecast via the emby app without any issues.

Steps to Reproduce

1. upgrade to emby Linuxserver.io version:- 4.7.8.0-ls132 Build-date:- 2022-10-09T04:58:05-05:00
2. cast with emby app to chromecast
3. enter htop, glances or similar process viewer
4. watch how ffmpeg goes crazy....

Environment

Command used to create docker container (run/create/compose/screenshot)

version: "2.1"
services:
  emby:
    image: lscr.io/linuxserver/emby:latest
    container_name: emby
    environment:
      - PUID=1000
      - PGID=1000
      - GIDLIST=44
      - TZ=Europe/Amsterdam
    volumes:
      - <path>/Config/Emby:/config
      - <path>/Tv:/tvshows
      - <path>/Movies:/movies
      - <path>/media:/media
    ports:
      - 8096:8096
    restart: on-failure:5

Don't dare to run it on chromecast again since then it was up to > 300% cpu usage and honestly my server is not a fancy machine and i don't really know how many more crashes the cpu can take 😿

Any advise on how to fix this would be much appreciated.

And while i'am here I just wanna say I have been using linuxserver docker images for years now, and this is the first time i ran into any issues (that i didn't cause myself) so just want send you all some ❤️ say thanks for all the AWESOME work you do! You guys truly rock!!!!
