I am making a project in Java. It is through hibernate and JMF. Basically it is project of Audio/Video/Text Chatting. in this, text chatting is running but when I make a audio call to another user, a exception appears.
java.lang.IllegalArgumentException: Line unsupported: interface TargetDataLine s
upporting format PCM_SIGNED 8000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian
I think it’s because of unsupported audio format by system I/O 1 2. Query your system for the list of proper formats.
