I use JMF (JMF 2.1.1-FCS for Linux) in Linux os (Redhat 6.2 + 2.2.14 kernel + JDK1.3.0). A java video player which uses the jmf api, streams from a rtsp server. Sometimes, when starting (to connect & play), the player hangs without playing. Once Player.start() is called, after getting some RTP data, " de.hiqos.media.protocol.rtsp.DataSource.stop() " is called by tha Player (why???). ( But it never started playeing only got some RTP data). It appears that it hangs during Realizing or Prefetching state of the controller. Below I provide the debug messages. I would appreciate if anybody can help me resolve this problem. Thanks in advance. Rgds Thava java Cutter javax com.sun com.ibm Protocol-Prefix "de.hiqos" set.
