Romain,
Using your notation, is there no way to set B (target encoding) from
Liquidsoap? Do we need to actually modify the xml file to set the target
encoding? The reason I am so confused is because the icecast documentation
page implies that this can be changed remotely.
For non-Ogg streams like MP3, the metadata that is inserted into the stream
