Weird subtitle bugs

[azukaar]

I am experiencing a weird issue with a particular movie, that I cant reproduce with other players. The movie itself does not seem to have any subtitles:

But playing that movie on the FPV player somehow displays subtitle. Even if I force them off with

              player.activeSubtitleTracks = [];

Even more weird, if I select an external subtitle, I get an overlap (here German, the ghost subtitle, and then japanese on top, the external one)

              player.setMedia(
                  "${widget.item.originURL}${exSub.link}", MediaType.subtitle);

any ideas what's going on?

show me the log. It can be closed caption embedded in video stream, so you can not see subtitle track. You can disable closed caption via player.setProperty("cc", "0");

I still see the subtitles with player.setProperty("cc", "0");

here are logs: https://pastebin.com/vePdjxkE

Thanks

[wang-bin]

OK the issue is not in FPV closing now thanks
