Recording and Downloading issues with yt-dlp

[Alan2154]

Hello

I tried to use yt-dlp to record livestream from this link "https://nifc77.dcs.redcdn.pl/livedash/o2/NIFC/live/konkurs-finaly-2021-4k.livx?indexMode?startTime=656526600000&startTime =656526600000"

For livestream, it can only record a video of 30 secs and then stop automatically. Is there any way to keep recording until the whole video finishes?

Another question is when I use it to download the finished video with the linked I mentioned above, I find that video and audio are downloaded separately and they can only be merged when everything finishes. If I pause the downloading process with ctrl+c, what I get is only part mp4 file without audio track. Is it possible to pause anytime as I want to get the complete video which is ready for watch? Thank you!

Here's my code
youtube-dl\yt-dlp.exe "https://nifc77.dcs.redcdn.pl/livedash/o2/NIFC/live/konkurs-finaly-2021-4k.livx?indexMode?startTime=656526600000&startTime =656526600000"

He want's the URL to the web page that plays the video. But I had no problem downloading 4 hours worth using your command line.

I think the problem is only 9 fragments can be found at one time rather than continuous ones.

Yes, but I managed to record the livestream with streamlink rather than yt-dlp eventually.

You could also add this to the yt-dlp call arguments:

--downloader ffmpeg --downloader-args "ffmpeg:-t 180"

In this case it will make the download file 180s long.

And for a certain resolution:

-S 'res:500'

This will get you the vertical resolution 500 or less. I use it to get 480p when the actual format sometimes may be 488 etc.
