Subtitles have incomplete names

[solimm4sks]

Steps to reproduce

Look at the subtitles in this video: https://www.youtube.com/watch?v=GroV8G4Amg8 . On LibreTube they are called: None, English, English, (some japanese characters i cant read). On Youtube they are called: Off, English, English - Neobrane, Japanese (auto-generated).

The ones on the youtube client are much more descriptive.

Expected behavior

The subtitle (caption) track name is the same on LibreTube as it is on Youtube.

Actual behavior

It's not. It's less descriptive.

LibreTube version

0.16.1

Android version

10

Other details

I especially have gripes with "English - Neobrane" being turned into "English", since that makes it hard to differentiate between the two English tracks.

https://piped.video/watch?v=GroV8G4Amg8 shows the same captions as LibreTube, thus it's either not supported by the Piped backend or the NewPipe Extractor to extract the extended language name.

The caption names in LibreTube are the ones returned by the Piped backend.

[Bnyro]

I can confirm it's a NewPipe Extractor issue.

@Bnyro This is highly likely to be a bug on your side not NewPipeExtractor, so I suggest you reopen this.

On Piped it's because they haven't configured shaka-player to use the label, so it defaults to displaying the name of the language instead, also shaka-player deduplicates based on language and role, which is why it is only showing one of the tracks. (look at the trackLabelFormat option, which Piped doesn't set: https://shaka-player-demo.appspot.com/docs/api/shaka.extern.html#.UIConfiguration)

This is probably a configuration issue on your side too.
