The fact that `icy.update_metadata` works for vorbis is really just by "luck". Icecast has an extensive support for vorbis stream and knows how to insert new metadata into them. There's no such support for other codec supported by the ogg container, in which case the function does nothing. Originally, this function is intended only for format that send metadata using the icy metadata protocol (see: http://www.smackfu.com/stuff/programming/shoutcast.html) I believe that your glitches problem is a really annoying issue with players not implementing the ogg stream format correctly. Essentially, if an ogg stream has multiple tracks, they all follow each other in a concatenated matter. However, some players are implemented with only a single track per ogg stream in mind and that causes issues, either playback stops at the end of the first track or you have glitches. Second thing is, when you insert metadata into a ogg stream, it will finish the current track and start a new one, beginning with the metadata you want to insert. Thus, triggering the issues on track change I explained above. This has been going on for years and it's pretty annoying to know that some players still haven't been fixed yet. Your best bet if you need to fix it would be to strip all metadata from the stream and use an out of band mechanism to display them, for instance on your website. Romain
