A docker image that sucks in the KFJC netcast stream and spits it out as hourly .mp3 chunks, served up via http on port 8888.
- Check that you like the options in
config.sh ./build-and-run.sh- Gawk at hourly .mp3 output on port 8888, and/or write a script to grab mp3s as they come.
Don't forget about disk! Each hour weighs in at about 57.5Mb, which is about 2.76Gb for 48hrs or 19.32Gb for 2 weeks.
The main entry point is ripper-bin/main.sh. In summary, it does three things:
- ffmpeg continually streams and segments
- Every 60 seconds:
- Check which DJ is signed in via query to
kfjc.org/api/playlists?id=0(append name to dj_signin_log.txt) - Check previous playlist info from
kfjc.org/api/playlists/previous.phpand dump that in an .id file - Check for ffmpeg output files that are no longer being recorded to (ie, not modified for at least 30sec). If there's a new file:
- See who appears most in dj_signin_log.txt and choose that as the DJ name for the hour; rm dj_signin_log.txt to clear it for the next hour
- Move the correctly named output mp3 file to the export directory
- Check which DJ is signed in via query to
- Serves files from a simple HTTP server on port 8000 (because FTP or NFS configuration is a royal pain in the arse).
Directories are relative to /ripper. Use ?html=true for a slightly more useful view; otherwise plain text directory listings are provided for machines to interpret.
/dj_signin_log.txtshows who's been signed in each minute since the top of the hour/exportholds completed 1hr mp3 segments/incompleteholds mp3 segments less than 59mins (eg, the segment between ripper start and the top of the next hour)/recordingholds the mp3 currently being recorded. You can check the modification time to see if ripper is active.
- Move files out of recording dir on start
- Extract more variables into config.sh
- Run readonly image; don't run as root
