Hello -

I normally use Winamp to play music, but today I was using VLC (on Windows) and was dismayed to find it does a bad job of playing back Ogg Vorbis streams from Icecast. The audio drops out briefly every time the metadata changes. I had this same problem using Rhythmbox on Ubuntu.

The stream in question was my own:
http://212.72.165.20:9020/radiosix.ogg
The source is OTSJuke->OddcastV3. Is there something wrong with the stream? Or are there just lots of broken players out there?

You might want to try reporting this to the VLC people.

Well, I mentioned the problem on the VLC forum, and the reply was:

Quote:
The audio stream is interrupted. the old "track" becomes invalid, and a new one needs to be added and the decoder needs to be reinitialized. It's caused by the way the streaming occurs. Instead of a continious encoding of vorbis, a new encode is started for each song (playback of a song).


I asked if they would add this problem as a bug to their tracker, and there has been no reply for several weeks now. So I guess they don't care, or they don't think it's a bug.

Anyway before I give up, perhaps someone here could put me right: Is the Ogg stream I'm talking about correctly named a "chained" ogg stream, and is there anything in the spec that says it should be played without gaps?

The vorbis spec is gapless, and many other players don't have a problem with header changes. On receiving a new set of headers, yes certain initialising needs to be done, but that is only for some internal structures, it doesn't affect the pcm, maybe they are re-initialising too much.

Thanks for that. Glad it's not just a user error... Smile
