Unable to download video subtitles for 'live_chat': Expecting value: line 1

[Yannf]

Getting this error message even though subtitles are unchecked: "An exception occurred: DownloadError: b"ERROR: Unable to download video subtitles for 'live_chat': Expecting value: line 1 column 1 (char 0)" [https://commons.wikimedia.org/w/index.php?title=Commons_talk:Video2commons&oldid=826276202#Subtitle_error%2C_even_when_subtitles_are_unchecked]. I get this error repeatedly.

we need a way to ignore this live_chat thing.

potential positions for rewrite https://github.com/toolforge/video2commons/blob/0a7eb3ecdc84bf6014cbc52622e4a3be1fd583b5/video2commons/backend/download/__init__.py#L58

if i understand correctly, this portion of code passes these params to https://github.com/yt-dlp/yt-dlp/blob/master/yt_dlp/YoutubeDL.py . then, they deal with allsubtitles like this https://github.com/yt-dlp/yt-dlp/blob/6a9c7a2b52655bacfa7ab2da24fd0d14a6fff495/yt_dlp/YoutubeDL.py#L524 https://github.com/yt-dlp/yt-dlp/blob/6a9c7a2b52655bacfa7ab2da24fd0d14a6fff495/yt_dlp/YoutubeDL.py#L2970

i think, asking on stack overflow or reddit, "how to download all subs except live_chat while using ytdlp", will help. or, i probably just found a method.
