I'm wondering, is there some way to tell Jellyfin to just transcode or reencode all my media for a particular client? And have that stored and used? I'm just thinking that each clients have different support and it's not always possible to get all the stars aligned, but jellyfin knows when a transcode is needed based on the client profile.

I guess I can do with hand break or something, but yeah... Any thoughts? Thanks.

Jellyfin has no support for creating transcodes in advance. If you do use handbrake to create another version, jellyfin supports having multiple versions of an item, and you will see a dropdown selector for which to play similar to how you can choose an audio track.

Afaik multiple item merging is only automatic for movies at the moment. Support for merging of show episodes is still WIP. (There's a PR on Github)

I tried to do this changing DTS to aas 5.1, but it seems to pretty stereo on the Roku. It's this bit supported?

On my phone I see it listed as 6 track aas.

Not sure, to get surround working it needs to be supported on the particular client.

If it's not, you can still select the track, it'll just be downmixed to stereo.

Ok I found the information here https://developer.roku.com/docs/specs/media/streaming-specifications.md

Looks like aac (which is what I meant) is capped to 2.0. let me see if I can do ac3 or some other output format.

Yeah, I guess I'm just not sure how to really understand what transcoding is supported... Maybe I should try pcm lol.

You can use handbrake or something like tdarr to have specific transcodes created.

It is just a trade off of whether you want to buy more storage or use more compute power when streaming.

Never heard of this. I will investigate if this can fix up things for me 🙏

Jellyfin doesn't support this and is unlikely to add it, even as a plugin.

There are several tools out there that can automate converting a large library such as:
https://github.com/mdhiggins/sickbeard_mp4_automator
https://github.com/HaveAGitGat/Tdarr

And you can see a supported codec grid on here:
https://jellyfin.org/docs/general/clients/codec-support/

It seems like an mp4 file, with H264 video and ACC audio would be the safest bet, with transcoding only occuring when the client resolution is less than the native video resolution.

edit: This post doesn't appear to have federated. As it contains links to tools which can perform the desired transcoding, I'm bumping it in the hope of it being sent.

Yeah it's ok, I don't have a massive collection and have started realizing with the Roku audio transcoding happens more when not needed.

I think you can have some that will create the transcode, don't think it is automatically for a client.

Good luck

Yeah, Ive started to reencode most of my videos with EAC3 instead. This resolves a lot of issues, including the DTS studdering on the roku client.
