Timer for streaming

[gioreva]

How can I record only a limited time, a streaming ?
30 minuts and stop.

I don't want to cut a video.
I want to stop the download after half an hour, otherwise download indefinitely.
I plan the recording at a certain time, which lasts only half an hour.

Can you provide an example? Right now I can only guess your requirement.

Assuming you have ffmpeg installed. Does the following shell command work for
you?

youtube-dl -o - -f best 'https://www.youtube.com/watch?v=BaW_jenozKc' | ffmpeg -i - -ss 0 -t 30:00 -c copy out.mkv

The above command downloads the first t minutes of the video
where 0 ≤ t ≤ 30 and then outputs it as out.mkv.

Does it work for you?

This for windows ?
Your example download full video, then ffmpeg cut 30 mins
I need to record on the tv, streaming is unlimitated time.
I want to recorder documentari, 30/50 minutes, from continus channel.
youtube-dl http://tv.net:2300/user/password/channel -o ufo.avi

No, it is not. But it can be easily changed to work for windows. First, download youtube-dl and ffmpeg <https://www.ffmpeg.org/download.html>.

Your example download full video, then ffmpeg cut 30 mins I need to record on the tv, streaming is unlimitated time. I want to recorder documentari, 30/50 minutes, from continus channel. youtube-dl -o ufo.avi

Then run the following command:

youtube-dl.exe -o - -f best "http://tv.net:2300/user/password/channel" | ffmpeg.exe -i - -ss 0 -t 30:00 ufo.mkv

Finally, the file can be played by vlc <https://www.videolan.org/vlc/>.

Just adding to the answer...

Piping the output into ffmpeg causes a high CPU usage on low performance devices, like Raspberry Pi, that otherwise would not be present without the pipe.

A faster approach would be ffmpeg -vcodec copy -acodec copy so there is not transcoding.
