Auto Archiving function for Icecast.
Hello:
Does anyone know how to set up auto-archiving with icecast. I have an
encoder coming in with a radio station. I want to create hourly mp3
archives of their streams that are coming to my icecast server. Got any
ideas?

...m, you can calculate the byte offset
and amount of bytes to cut from the dump file (e.g. 128 kb/s stream is
((128 / 8) * 60) kB/minute, a half hour section is ((128 / 8) * 60 *
1000 * 30) bytes)
- use dd to cut the desired mp3 data from the current dump, e.g.:
dd if=session3.mp3 of=1000.mp3 bs=BYTES_PER_HALF_HOUR skip=4 count=1
where skip=4 tells dd to skip the first 4 half-hour segments
You can cut with dd if you take care to cut by the mp3 frame boundaries.
Of course, this only works with fixed bitrate encoding. Also, some mp3
experts would argue that there will be some mess at the boundries of the
c...
