Looks nice (although I didn't test it yet). I noticed a few things that could be improved.
Also I think adding a transcoded 1080p (maybe even a 4k one) would be useful. People may store 4k BDRemuxes, so getting a stream that's not full blu-ray bitrate would often be needed in that case.

Graphic Subtitles don't work when transcoding playback, that is quite an issue...
Edit:
In general subtitles and track selection is kinda all over the place, sometimes it shows options sometimes it doesn't, sometimes it shows track's language and sometime it doesn't. Also there's no indicator in the quality selection as to what is selected. There should be a checkmark or something...

hey, thanks for testing! for PSGSUB I noticed I never get a deliveryurl for this specific codec only. not sure why the path is always null. However there is one more thing i would like to try.

As for audio tracks there is no logic to handle extra audio tracks yet. I haven't even thought about it, I will need to have a look.

If it gets transcoded anyway, why not just add a way to deselect certain audio tracks from being downloaded?
Also would be nice to have a way to change that: "All transcodes to H264 and AAC-128k"
(haven't tried the apk, just assumptions from the issue description)

Just to let you know, I have been looking at this PR from time to time.
Once I have a little more time to spare I will take a look at it in more detail.

Any chance this gets merged soon? Streamyfin has a similar transcode download feature but IMO Findroid is a much better UI.

It was posted on this jellyfin feature request that has been open for 5 years with over 300 upvotes. I imagine many of those people would love to see they have multiple mobile app options for transcoding offline downloads.
