JMF error - Format of Stream not supported in RTP Session Manager
java.io.IOException: Format of Stream not supported in RTP Session Manager
at com.sun.media.datasink.rtp.Handler.open(Handler.java:139)
why this erro occors?
I already created the DataSink.
When I try to do this...
dsk.open();//here the error got
dsk.start();
Code of server of media
I want to sent audio (wav) like a radio, but from file. Without stop to send streaming. PullBufered

Gives that output console.
All methods are executed but the last doesnt works.
The method that open the DataSink.
What can I do?

Since already thanks so much.
Exactally in this method raises erros.
Ive tried another formats (avi, mp3) but all with the same error, what I can do?
