I am using JMF jar file, but i am only able to listen the sound but cant view the movie.
Unable to handle format: RLE , 800x600, FrameRate=14.6, Length=31280
Failed to realize: com.sun.media.PlaybackEngine@17590db
Error: Unable to realize com.sun.media.PlaybackEngine@17590db
some error i got when trying to play the video.
JMF is basically dead
You can use xuggler to play wmv files in java swing.
