Description

If I remove the "--all-subs" option, there's no error and file downloads fine

[blackjack4494]

I tried your video but it didn't work. It says not available. Must have been a live stream and or is now private. However if I use any other video link I get no error at all when using --all-subs.

[quekky]

The link is time limited for a few days only

Try this link. The error only occur for videos with chapters and subs. I'm using Windows, not sure if it errors on linux

Okay I see. I may know what triggers this.

[blackjack4494]

Huh. I am a bit lost tho it may be because I haven't spent a lot of time on this.

The live chat fix somehow introduced another error.

# subtitles
video_subtitles = self.extract_subtitles(
    video_id, video_webpage, has_live_chat_replay)

When I simply replace has_live_chat_replay with False there is no problem whatsoever.

If I change something else related to is_live everything works normal again but live streams cannot be downloaded then.
It's just tricky for some reason.
I somehow blame youtube for this 😄
They leave the live stream chat info on videos that aren't live anymore and do not have any chat anymore..
