@ -19,6 +19,8 @@ Changes in 0.4.0, (SVN trunk):
|
||||
* various:
|
||||
- [ADD] Allow ezstream to use TagLib for reading metadata from media
|
||||
files. TagLib (libtag_c) is now an optional dependency.
|
||||
- [ADD] When built with TagLib support, include the song length in the
|
||||
"real-time" information line, if available.
|
||||
- [ADD] New <metadata_progname> configuration option, which causes
|
||||
metadata to be read from the output of an external program or
|
||||
script.
