- * Search for Track numbers which will identify essence element KLV packets.
- * 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) then add MetaDataSet to MXFContext.
- * Metadata parsing resolves Strong References to objects.
- *
- * Simple demuxer, only OP1A supported and some files might not work at all.
- * Only tracks with associated descriptors will be decoded. "Highly Desirable" SMPTE 377M D.1
