In any ogg streaming context they<br> will not start at 0, and the player needs to handle that properly.<br> <br> e.g. try this:<br> <br> $ wget -O radio.ogg '<a href="http://stream-uk1.radioparadise.com:80/rp_96.ogg" target="_blank">http://stream-uk1.radioparadise.com:80/rp_96.ogg</a>'<br> <br> control-C after a few seconds, then:<br> <br> $ oggz-dump radio.ogg | grep gpos<br> <br> There isn't really an easy way to make oggmux start at 0 every X seconds<br> or minutes.<br> <br> Cheers<br> -Tim<br> <br> <br> _______________________________________________<br> gstreamer-devel mailing list<br> <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a><br> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a><br> </blockquote></div><br></div>
