Metadata from Traktor

[Satariall]

We use Traktor PRO for mixing dj sets. So, now we need to get current play sound via tracks/samples metadata.

Inside Traktor we see that preferences:

When we start broadcasting to icecast all be ok - mount is makes and we may listen new station. But no metadata update in that. So in internet have some tools, such as http://en.www.ali.dj/traktor-scrobbler/

They functional - emulate server and grep getted metadata. Then they save them to file (optionaly - make tweet with current song). I test that tools - all ok, Traktor is send metadata.

So my question - why this metadata not be update in icecast? What i may do for diagnose that issue?

Thanks

Ofcouse, debug log in level 4 doesn't return any interesting info about metadata. But they have connected useragent

Now i have received meta. But my logic is broken. If track have hot IDv3 tags Traktor send filename without extension. But if i write only artist and title fields metadata have not visible in icecast. But when i set "Genre" field - then all be full ok! I don't know why it is.

[karlheyes]

With vorbis the comments are in the 2nd header packet, and artist/title is picked out just before the audio_ stats are set. We don't use genre as a optional switch for this so artist/title should appear even if genre is missing, but it is possible that the source client is doing some sort of filtering on genre.

Yes, u right. This is traktor logic. With them have another problems (such as send metadata info from not active listen deck [dj preview af next mixing], but it is they local problems). Thanks, all ok on Icecast
