  • How to schedule ffmpeg audio streams of varying lengths with titles and metadata?

    10 September 2021, by underdoot

    I have a Shoutcast stream that I want to archive 24/7 with ffmpeg. Shows on this stream vary in length between 1-3 hours, but have a regular weekly schedule.

    


    How do I download these shows, and give the files appropriate titles according to the show playing (determined by day of week and hour of day)? I want the title of files to be along the lines of "2021.09.21 - 0300-0400 — Radio Show Name" and automatically add to a set folder. I also want to run the program only once, and have it running in the background constantly.

    


  • Copy live stream without overwrite previous file

    2 February 2020, by Panagiotis

    When I login I automatically start a script, that downloads a radio stream with ffmpeg.

    ffmpeg -i \
    
http://139.162.14.151:9090 \
    
-c copy output.mp3

    But each time it is asking me to overwrite the file. I want it to automatically create a new file without overwriting the previous one.

  • Problem updating drawtext with file using ffmpeg [duplicate]

    17 November 2020, by drmobbins

    I have a shell script that runs to combine a 24/7 AAC audio stream with a 720p HD picture/background and streams that output live to YouTube. This is for an internet radio station. The script works perfectly except for the drawtext option. The drawtext option references a file that is updated every 15 seconds (using Python and Cron) with the correct song metadata (from the radio automation suite) and is supposed to print the contents of the metadata file to the screen. This happens one time when the ffmpeg command is run in the script, but doesn't update after a song change.

    


    I would assume that since the metadata file is changing every 15 seconds on the server that it would update the song details in the output video that could be seen on YouTube...but it doesn't.

    


    #!/bin/bash

 -f flv $YOUTUBE_URL/$YOUTUBE_KEY


    


    What am I missing that will make the output continually check for file changes and use drawtext to display the contents. Thanks in advance!
