Internet Radio meta data?

Hello.
Is it somehow possible to stream/display the internet radio stream meta data (such as current song title, artist, album)? Some stations e.g. shoutcast mp3 transmit this data. My Sony BDP-S370 shows icons for these, which are blank.
Thanks in advance.

Actually audio files transcoded with vlc seem to not have artist/title/album meta data either.

This technology is largely static, first device requests information on resources, then requests a stream. Ie at the time of request information about the resource is no information about what is in the stream.

I am trying to investigate if there is a commandline option for VLC to query this data from the file, before streaming/transcoding.
EDIT: Actually WMS knows this info already for m4a files. It's just not being streamed when being transcoded by vlc. I am just wondering, does vlc stream directly to the device, or does wms process the transcoded stream?

Depends on transcoding profile. To read the properties WMS uses the original stream. To the device may be transmitted transcoded.

I usually try not to use transcoding profiles unless I need to override a particular stream or file's settings. I leave no profile assigned to the "Movies", "Music", "Internet-Television", "Internet-Radio" Transcoding File Params settings. If the file extension is missing from the list in Settings -> Device -> "Embedded File Support", then it gets transcoded automatically. I am not sure which settings it would be using in this case though.
Is there a transcoding profile where the stream meta-data is passed to the device? Or would somebody have to write one? Or would this need to be a new function added to the WMS source code?

VLC and FFMPEG support adding meta-data in the stream, but they are set in the call parameters, ie they will not change by changing composition.

Thanks for that. Does that mean it could possibly work for playing individual music files, but not internet radio (where the songs change)?

For Internet radio this will only work if you save the original stream or if the transcoder will add meta-data in the output stream automatically when changing songs.
