( http://www.chiariglione.org/mpeg/faq/mp4-sys/sys-faq-bifs.htm ) The BIFS Track contains information how the individual objects(could be an audio/video stream or a shape...) inside the MP4 file will get presented. The OD (ObjectDescriptorStream) contains the ES-Descriptor for the audio/visual objects which are mentioned in SceneDescriptionStream(BIFS Track). Osmo4( http://gpac.sf.net ) has a good support for it but isn't the fastest player. Richard -- +++ NEU: GMX DSL_Flatrate!
