How to record online radio on linux schedule?

Question

linux

You need to record only one transmission (an hour of time) on certain days at a certain time.
Unfortunately Moskva.FM no longer provides recordings, you will have to write yourself.
I am using Linux. How to start recording in VLC on a schedule does not quite come to mind, and if another media file is launched at that time, VLC can switch, stop writing, and start playing what I started, forgetting about the recording.
Tried streamripper:

date=`date +"%Y_%a_%b_%d_%H%M%P"`
url=http://radio.2kom.ru:8000/SportFm.m3u
output_filename=radio__.${date}
duration=3600 
output_dir=/home/pi/radio/recordings
cd $output_dir
streamripper $url -s --quiet -d $output_dir -l $duration -a $output_filename -o always

I put it in cron, it writes something, but the file remains in the incomplete directory and is not played, although there are 100+ meters of weight. I redirect the output to a file (with --quiet errors should still be thrown), the file is empty. Tested for several days - the situation is absolutely the same.
Does anyone have any idea how to fix streamripper, or how to run VLC or some other solution?

Option with mpvand at:
