It doesn't matter if it doesn't play it, before I had it like this on another service and 90% of the content is played without problem for the majority
If it can be deactivated, I would be interested to know how.
You have to re-encode with the codecs and containers I stated above.
Is that done within jellyfin?

As in with another computer separate from the server using something like Handbrake or FFmpeg to convert the media. You would then move the converted media onto your Jellyfin server when they have been converted.

I can't do that because it's a lot of content and it would take a lot of time, but everything is in mkv which allows it to be played on all devices.
Can't you cancel the transcoding of everything even if that means some content can't be played?

@TheDreadPirate already responded with the codec that are most likely compatible with a wide verity of clients and hardware:

AAC stereo audio
SRT or burned in subtitles
MP4 container
You need to verify what codecs the videos and audio are encoded in inside your MKV containers as well.
H265 video will be less portable across clients than H264.
FLAC audio will also be less likely to play well on most clients as compared to AAC audio.

The option "Allow video playback that requires conversion without re-encoding" is the option that enables remuxing to happen.
Just uncheck all three options (the two for transcoding, and the one for remuxing).
Doing so will result in your users getting denied when attempting to play a video that's not supported on their client.

You can disable transcoding, but then your users may not be able play some videos on some of their particular devices. MKV is just a container. The codec of the video, audio, and subtitles are what matter.
RE: Problem with CPU at 100% and RAM does not stop increasing - franciscok - 2024-08-21
Yes, I have already disabled the video, the one that causes problems is the audio, if I disable it it doesn't play...
I'm also doing tests, right now with 75 active users everything is working fine but when someone new enters the CPU loads to 80% for a few seconds and then stabilizes again.
If I change and only leave 150 users instead of 450 and the server goes from 40cpu to 36cpu and from 5gbps to 1gbps, will it work without giving me problems?
