Testing the JMF media framework today, there are many problems from configuring JMF to running the test program. A few points to note so as not to forget
错误1： java.lang.IllegalArgumentException: amount of data to read does not represent an integral number of frames
It's because the sun jdk version is not installed
Solution: install sun jdk, compile and run with sun jdk;
错误2：javax.media.NoProcessorException: Error instantiating class: com.sun.media.protocol.javasound.DataSource
javax.media.NoDataSourceException: Error instantiating class: com.sun.media.protocol.javasound.DataSource : java.io.IOException: Cannot open audio device for input.
It is because of the error that the audio/vedio connection is not released
Solution: Release the connection
