Transcoding/conversion being forced, when it's not required (HDR and/or high bitrate)

[Skin80]

Software Versions

• Jellyfin Server Version: 10.10.0
• Roku Client Version: 2.1.4

Describe the bug

https://github.com/jellyfin/jellyfin-roku/tree/master/source/utils/deviceCapabilities.bs forces a hardcoded bitrate limit of 40Mb/s on all video files (except h.264 codecs where the hard limit is 10Mb/s).

It also forces transcode/conversion of any file that is not "SDR" (i.e. HDR/HDR+/DoVi).

Whilst understandable from Roku, as they need to support their weakest products, it makes no sense for Jellyfin to hardcode those limitations into the app.

Jellyfin already has the ability to set a maximum bitrate by the user. Why not simply allow the Roku default to be overridden by the user?

As it stands, I have HDR video files with average bitrates of over 70mps that play on my Roku device.

However, all these files are being converted to a .ts stream, causing issues with correct recording of timestamps and resumption of video playback.

How To Reproduce

1. Playback any video file with a video bit rate over 40mbps and/or HDR/HDR+/DoVi.

Expected behavior

Direct play/streaming of valid containers and formats, without the need for transcoding or conversion.

Connection Information

Local server, over HTTP

Additional context

Why aren't device profiles open? I can edit DLNA profiles, but not the profiles of devices "officially" supported by the app, why?
The average user won't touch them, but making "advanced" users build their own version of the app in order to make simple profile adjustments is an odd choice.

Have you tried disabling the "Bitrate Limit" setting on the client? If I disable that setting, I'm able to play HDR videos (the TV shows the HDR logo at the start).

[cewert]

What if we automatically remove all bitrate limits if we detect the server is local? Looks like we have the data already m.global.session.server.localURL and m.global.session.server.url

edit: Jimi suggested we disable this feature by default and I agree.

[jimdogx]

I don't think we need to check for local vs remote server as the Bitrate limit setting can already be toggled on/off. Never heard back from @Skin80 on whether or not this worked for them.
