| | A script to .... |
|
| |
|
| Annoyingly, mplayer can't be used to directly play a "pls" file (common format for Internet radio stations). However, mplayer almost always *can* be used to play the stream, you just need to feed it the direct URL of the stream, which listed in the pls file itself (the pls is simply a text file giving one or more possible URLs of the feed). In this case, a simple Python script extracts the URLs and passes it on to mplayer to do the actual work. An optional numeric parameter inidicates which URL to use if multiple URLs are present in the file.

| == Sample pls file ==

| Here's a sample of a pls file for [http://wfmu.org WFMU].
