Why is JF Transcoding?

[MediaMaan]

There is a setting to allow transcoding to HEVC.  Is that enabled?  If not, it defaults to only use H264.

Jellyfin also logs why it transcodes.

Thanks for your reply.
Yes, I have transcode to HEVC selected.
However I didn't think it should be transcoding at all.

I modified the Jellyfin client on my phone to use the Integrated Player instead of the Web Player. That has helped, and now it shows Direct Play.

I am still confused as to why the client provoked a transcode on a file which it could Direct Stream through.
