Now, when the stream is no more live and has been processed by YouTube, I can download chat replay without any problems with the same command line. But live chat has its own value because it contains deleted messages and messages before and after the stream. And of course, author may restrict access to the stream after broadcasting, so there will be no downloadable chat replay available.

Same issue here on every yt stream. I attached the full log as OP didn't: chd.txt

Edit: It's some kind of confirmation screen, using cookies from my desktop works. https://github.com/ytdl-org/youtube-dl/blob/master/README.md#how-do-i-pass-cookies-to-youtube-dl

chat = ChatDownloader(cookies='cookies.txt').get_chat
mascarell commented 1 year ago

Same issue here.

I personally would not want to use a cookies file, happy to donate if anyone can look into it as I use the library for a bot while streaming

Consent cookie has changed. I changed _initialize_consent() in the youtube.py accordingly to this: https://github.com/yt-dlp/yt-dlp/commit/378ae9f9fb8e8c86e6ac89c4c5b815b48ce93620 and it works now.

HSDRC commented 1 year ago

Confirmed, in youtube.py file _initialize_consent should look like this:

    def _initialize_consent(self):
        if self.get_cookie_value('__Secure-3PSID'):
            return
        socs = self.get_cookie_value('SOCS')
        if socs and not socs.value.startswith('CAA'):  # not consented
            return
        self.set_cookie_value('.youtube.com', 'SOCS', 'CAI', secure=True)  # accept all (required for mixes)

Then all things work back.

Thank you. I have changed this directly in the Python37-32\Lib\site-packages\chat_downloader\sites and now it works. Waiting for release.

xenova commented 1 year ago

Thanks for identifying the problem! @armislv, @HSDRC, or @pboettcher, would one of you like to submit a PR for this?

Done. Please do not judge strictly because it is my first pull request.

It is actually the code of @HSDRC in there. I was just practicing making the pull request.
