ogg decoding without "synchronization"
Hi list, I have an artistic project in which I manipulate streams. At the moment I'm using ogg vorbis streams, Icecast servers and the multimedia puredata software. In this project I would like to read an ogg stream from an icecast server and decode data in the order it is incoming. I would like to skip the step that is reordering the data conforming to the order it was send. Do you know

ogg decoding without "synchronization"
...Ogg streams over HTTP, which is itself carried over the TCP protocol, which does the reordering inside the kernel. You could do what you want if you sent the vorbis data over RTP (in UDP datagrams) instead of icecast's ogg-over-http approach. I believe gstreamer can do this, with rtpvorbispay/depay, etc. There's also some sample code at http://svn.xiph.org/trunk/xiph-rtp/ (possibly it's out of date relative to the spec; I haven't looked at it in a few years). UDP packets aren't reordered by the OS kernel's networking stack so you can access the delivery order directly in y...
