Decoding JSON fails with non-English LC_NUMERIC

[jtojnar]

Turns out VLC uses old and buggy dkjson version, I opened an issue against VLC.

If you encounter videos mysteriously not playing, try adding latest version of dkjson to ~/.local/share/vlc/lua/modules/.

Adding os.setlocale("C") to the beginning of the script solves it....

I would seriously advise against using that. setlocale(3) is not thread-safe and, if os.setlocale is just a wrapper around the libc function, there is a chance of it seriously fucking up VLC.

In worst case, you might get random crashes – much harder to debug than explicit decode errors.

If you really want to fix it, just download latest version of dkjson until code.videolan.org/videolan/vlc/-/merge_requests/3318 is merged.
