creating mov files with JMF
hello guys i am making a motion detection and capture program. i managed the detection code... the problem is writing video to a quicktime file. i made a record class which is used to record movie to a file. the recordFile(DataSource ds) in record class is used as the function for recording. I cannot get the thing to record. Can somebody help me. I send the DataSource ds which is the cloned version from the main motionDetection class..... please do help fast guys.
here is the record class
