I understand ur reluctancy, i used them on my Mac, MPV doesn’t support MacBooks anymore so the Jellyfin client took a hit ( video decoding isn’t the best). Phyn is almost the same compared to VidHub but they propose an all in one Jellyfin/Jellyseer app for a subscription, it’s free if u re just gonna use for Jellyfin.

I use VidHub on my IPhone and MacBook, there is also phyn as an option. All are present in the AppStore

if u re getting 3 to 4Gb out of a 40G x264, u re definitely losing a lot of data… With proper settings, It should be around 16 - 18G. AV1 can’t do miracles.
