Rasbperry pi 4 performance issues

[StarfoxHUN]

Ideally, you would get a beefier server.  The only workaround is to pre-transcode your media on a separate, beefier, machine to the following codecs.

Video: 1080P H264 main profile.  High profile, but not 10-bit, is usually ok as well.
Audio: Stereo AAC
Subtitles: SRT

Thanks for the answer. Sadly I need the original files in the pi too, so this is not really possible, unless there is some script that can automatically do it directly on the pi too (scheduling is not a problem, I have 3rd party program for that). Pre-transcode being slow is not an issue at all, if this works locally. But sadly creating such script is outside of my knowledge, so unless I can maybe ask help with that or ask for directions to where to look, sadly I cannot do this myself. Thanks so much anyway!
