[FEATURE] Get live chat when user goes live about chat-downloader HOT 10 CLOSED

Sure I can add something like this! 👍

Hi, I'm actually not sure what to do if the code becomes buggy after I tamper with it, so I'll just wait for the feature. Sorry to bother you, though.

No worries. I am currently working on improving documentation (and some other improvements), but I will get to it as soon as possible. If you don't mind, can you take a look at #61 (comment)? Just so I can close that issue. Thanks!

I already posted this, but I'm not sure if I accidentally deleted my post or if there's a network bug.
I made this shell script to achieve what you're trying to do.

#!/bin/sh
channel="$1"

get_live_url() {
	_channel="$1"

	_video_code=$(youtube-dl --list-formats --playlist-end 1 "$_channel/live" | grep MPD)
	if [ -n "$_video_code" ]; then
		_url=${_video_code#*be] }
		_url="https://www.youtube.com/watch?v=${_url%:*}"
		echo "$_url"
	fi
}

while live_url=$(get_live_url "$channel"); do
	if [ -n "$live_url" ]; then
		chat_downloader "$live_url"
	else
		sleep 60
	fi
done

Cool, I'll check it tomorrow, thanks for the reply!

Great stuff @alnj 😃

This functionality has actually already been implemented in the docs branch and will be released as soon as possible. It currently works with a channel url/id (e.g. https://www.youtube.com/channel/UCSJ4gkVC6NrvII8umztf0Ow or just UCSJ4gkVC6NrvII8umztf0Ow), and I will add support for custom urls shortly (e.g. https://www.youtube.com/c/chilledcow or https://www.youtube.com/user/xxx)

@alnj I'll be honest, I have no idea how to work this script out, where should I put the channel / video url?
@xenova When is this gonna be ready? And will it work with only the channel url, like the next upcoming livestream will automatically be saved? If yes, that sounds like the perfect feature for me, so thank you.

I am quite busy during the week with university work, so I can only continue working on it over the weekend. I will try get it included as soon as possible.

@artiction I initially made it for myself so it's a shell script that won't work on Windows (not sure what OS you're using).
After making it executable with chmod +x filename.sh you can call it with ./filename.sh [channel URL goes here]. This will run continuously, running chat_downloader on every public video, but you can also make it run on just the next one if you add a break or return in a new line after the chat_downloader line.

Sorry for the long wait... but I finally got around to adding this to the latest version (it was in the beta for the past few months).

You can now use the channel id of a user to search for live streams. If they are not streaming (i.e., no upcoming live stream or ongoing live stream), you will get the following message:

[INFO] There are no active or upcoming livestreams with a live chat. Retrying again in 30 seconds.

For example,

$ python -m chat_downloader https://www.youtube.com/channel/UC-lHJZR3Gqxm24_Vd_AJ5Yw
[INFO] Site: youtube.com
[INFO] Retrieving chat for "UC-lHJZR3Gqxm24_Vd_AJ5Yw".
[INFO] There are no active or upcoming livestreams with a live chat. Retrying again in 30 seconds.

Every 30 seconds, it retries and once the channel goes live, the chat will be captured.

Let me know if you have any further questions! 😃
