I suggest you test the difference with them step-by-step.

This is similar w/ our demos, since we don't use TextureData but a
direct texture object in TextureFrame.
Further more I assume you have installed libav/ffmpeg on your system.
You can enable the following debug properties for GLMediaPlayer:
-Djogl.debug.GLMediaPlayer
-Djogl.debug.GLMediaPlayer.Native
-Djogl.debug.AudioSink
-Djogl.debug.AudioSink.trace
-Djogl.debug.GLSLCode
