I don't believe
youtube-dl alone will do what you want. However you can combine it with a command line utility like ffmpeg.
First acquire the actual URL using youtube-dl:
youtube-dl -g " ://www.youtube.com/watch?v=V_f2QkBdbRI"
Copy the output of the command and paste it as part of the
-i parameter of the next command:
ffmpeg -ss 00:00:15.00 -i "OUTPUT-OF-FIRST URL" -t 00:00:10.00 -c copy out.mp4
The
-ss parameter in this position states to discard all input up until 15 seconds into the video. The
-t option states to capture for 10 seconds. The rest of the command tells it to store as an mp4.
ffmpeg is a popular tool and should be in any of the popular OS repositories/package managers.
