- * Search for SourcePackage which define tracks which contains Track numbers.
- * Material Package contains tracks with reference to SourcePackage tracks.
- * Search for Descriptors (Picture, Sound) which contains codec info and parameters.
- * Assign Descriptors to correct Tracks.

- * Metadata reading functions read Local Tags, get InstanceUID(0x3C0A) and then resolve Strong Reference from another object.
