I know this problem ist known. And I know, there is already a Ticket concering this problem.
But as this problem appeared already in the previous version and has not been solved yet, I'd like to give it some kind of voice.
In the 8.x.-brunch it worked fine, but since using the 9.x-branch the meta data (artist, title, album, ...) is not refreshed/reloaded during play of an audio stream. For me as an interessed user this means i have to pause and restart the stream to get the information updated. Which means that there is a gab of a second even with 32 kbit-streams! And that is imho not a "low piority" issuse.
As this problem is more than just annoying - it makes vlc unusable as a radioplayer - I hope someone could fix it. Unfortuantely I don't have any coding skills and can't do it myself. But for me it seems not too hard to handle for so. who's into it. Thanks a lot, guys! Really!
edit: If there is anything but coding I can do to help: please let me know!
edit²: Just an idea that came to my mind: What about a update button/hidden F5 function in the info window (crtl+i)?
