* Proxy Concept:
|
|
* 1. Connect to streamserver
|
|
* 2. Listen on localhost, let aRts connect to proxyserver
|
|
* 3. Write GET request to streamserver, containing Icy-MetaData:1 token
|
|
* 4. Read MetaInt token from streamserver (==metadata offset)
|
|
*
|
|
* 5. Read stream data (mp3 + metadata) from streamserver
|
|
* 6. Filter out metadata, send to app
|
|
* 7. Write mp3 data to proxyserver
|
|
* 8. Goto 5
|
|
*
|
|
* Some info on the shoutcast metadata protocol can be found at:
|
|
* @see http://www.smackfu.com/stuff/programming/shoutcast.html
|
|
*
|
|
* @short A proxy server for extracting metadata from Shoutcast streams.
