Subtitles not available

[2-4601]

Hello,

I have been using this absolutely wonderful plugin for several years. Thank you for making it. Your plugin has saved me from the horrors of hardware video decoding in web browsers as I can just rely on mpv to watch all Yle provided content.

Today I noticed something strange. Subtitles have stopped working in all the videos I tried. However, yle-dl still gets the subtitles. So I thought there might be some subtle change from Yle's side that yle-dl is able to still handle but causes issues with this plugin.

For example, downloading this short news video with yle-dl works:

$ yle-dl https://areena.yle.fi/1-66528750

The video is saved as MKV and it has subtitles – despite the error in the beginning.

However, playing the same video with mpv and mpv-yledl:

The video opens in mpv but there are no subtitles to choose from.

This happens with all videos now. There are no subtitles in any Yle Areena videos anymore when viewed with mpv and mpv-yledl.

---

I tested this with a clean mpv install. I.e., with an empty ~/.config/mpv directory, except .config/mpv/scripts/yledl_hook.lua.

mpv version: v0.38.0 (02254b92dd237f03aa0a151c2a68778c4ea848f9)
yle-dl version: 20240429 (0d7ae06c94fcecda1d421a805d1c41db26c81e7c)
mpv-yledl version: 0cc82b4
