| 34 | * Search for Track numbers which will identify essence element KLV packets. | ||
| 35 | * Search for SourcePackage which define tracks which contains Track numbers. | ||
| 36 | * Material Package contains tracks with reference to SourcePackage tracks. | ||
| 37 | * Search for Descriptors (Picture, Sound) which contains codec info and parameters. | ||
| 38 | * Assign Descriptors to correct Tracks. | ||
| 39 | * | ||
| 40 | * Metadata reading functions read Local Tags, get InstanceUID(0x3C0A) then add MetaDataSet to MXFContext. | ||
| 41 | * Metadata parsing resolves Strong References to objects. | ||
| 42 | * | ||
| 43 | * Simple demuxer, only OP1A supported and some files might not work at all. | ||
| 44 | * Only tracks with associated descriptors will be decoded. "Highly Desirable" SMPTE 377M D.1 | ||
