How to record dash livestream with yt-dlp?

[Alan2154]

Hello

I have issues on recording livestream of the link below
https://nifc77.dcs.redcdn.pl/livedash/o2/NIFC/live/konkurs-finaly-2021-4k.livx?type=vi...e=656615060853

As you can see from the code below, yt-dlp can only record for 30 secs and then stop automatically. Is there any way to keep recording until livestream ends?

yt-dlp doesn't record live streams. Anyway, you could try with ffmpeg as external downloader:

yt-dlp --downloader ffmpeg "https://nifc77.dcs.redcdn.pl/livedash/o2/NIFC/live/konkurs-finaly-2021-4k.livx?type=video&ft=1&id=20&bitrate=800000&startTime=656615060853"

Or with Streamlink:

streamlink "dash://https://nifc77.dcs.redcdn.pl/livedash/o2/NIFC/live/konkurs-finaly-2021-4k.livx?type=video&ft=1&id=20&bitrate=800000&startTime=656615060853" best -o video.mp4

There is something wrong with the first code.

yt-dlp.exe --downloader ffmpeg "https://r.dcs.redcdn.pl/livedash/o2/NIFC/live/konkurs-finaly-2021-4k.livx?indexMode?startTime=656700300000&startTime =656700300000"

You are welcome. Don't forget to add the dash:// prefix, otherwise you will not be able to download those live streams.
