Can't select subtitles, it jumps back to none

[ikheetjeff]

Describe the bug

Thank you all for this fantastic app.

When I click on a subtitle, I expect it to load. However, that doesn’t happen: it switches back to "none" and doesn’t display any subtitles. This occurs with all SUBRIP languages in this video. However, it doesn’t happen with all series/movies. I haven’t been able to find a reason why it doesn’t work with this file but does with other films/series.

I’ve tried the following:

• Reinstalled the app
• Created a new folder + file name without metadata
• Used a different subtitle file in the same language
• Used a different subtitle file in another language
• The file also had PGS subtitles, which I removed using MKVToolNix and loaded only the SUBRIP: still didn’t work.
• Converted the video to H264 using Handbrake. (idk why but yeah i wanted to try everything before making a issue here)

When I installed an earlier TestFlight build (1.2 (3)), the problem was resolved. The issue is also not present in the App Store version.

I suspect it is related to this PR: #1219
Hopefully, @cebrusfs, you can take a look at this due to your previous commit. My apologies if this tag is not appreciated.

This video shows the bug: (TestFlight 1.2 (4))

This is how it should work: (TestFlight 1.2 (3) / App Store version)

It might be some trick cases that my workaround doesn't handle well.

I think @LePips is working on refactoring related code in #1203. I hope it fix this if the whole logic is re-written.

BTW, it is good cases that we might want some unit-test to ensure this handled correctly.

[tobylibo]

I have the same issue.

[Firestorm7893]

Unfortunately I'm having the same issue as well.

[95mjeed]

This is the same issue I have

[95mjeed]

Last update in AppStore indicates that the issue solved , did you guys still have it.
Since I still facing the issue and tried everything to workaround it but no luck.

[HanHwanHo]

Last update & test flight

still facing the issue no luck

internal subtitles works but external subtitles switches back to "none"

[cebrusfs]

@LePips do you have any refactor progress could share? I am thinking if we should take immediate action to revert #1219 since the patch get more complain on this thread than #1207

[JPKribs]

I believe the goal is for this refactor to be shipped in the 1.3 final version:

#1265 (comment)

[justinkb]

seeing this issue still, shouldn't be that hard to fix, I'll take a look myself

[mattialuzi]

I have the same issue with version 1.2 and external subtitles (jellyfin server version 10.10.1)
