    > Jellyfin on iOS transcodes .ac3 to .aac causing 50%-70% CPU usage.

    Jellyfin on iOS does support ac3 natively though, it is just iOS only supports up to 6 channel audio so the 8 channel audio is getting downmixed. Can you verify that? And please don't check the use native player option in app settings, that player is worse than the web player.

    > 50%-70% CPU usage sounds really high to transcode a single audio stream but I’m new to all of this so I have no idea if I am incorrect or not.

    If you have a weak CPU (which probably is if you are running 8100T at its TDP which is only as fast as an N100), multi-channel audio processing could be quite intensive depending on the contents especially when it is both transcoding and down-mixing. But 70% overall is still a bit too high. Does the CPU run at max clock it could when having this usage and does most of the usages comes from ffmpeg?
