- 1. Complete known box types for BMFF, MOV/QTFF, QTIF, 3GPP/3GPP2, JP2, JPM, DVB and DASH
- 2. Find and implement the optimal reusable API for BmffReader/BmffWriter for all expected and potential uses (seeking specific atoms, copying with changes or reordering)
- 2.1. BmffReader and BmffWriter need options flags
- 2.2. BmffReader should handle both sequential and seekable streams -- Sequential handling needs an event model!
- 2.3. Need an equivalent of XmlDocument for Bmff files -- As output from BmffReader and input to BmffWriter.
- 3. Implement 'moov' compression (decompression is already supported)
- 3.1. Determine the best way to expose the compressed 'moov' through BmffReader -- an AutoDecompress option flag?
- 4. Add more XML comments for design-time support!!!
- 5. Consider converting public unsigned properties to signed of a larger size with range checking for CLS compliance (ugly, but what can you do?)
- 5.1 What the heck do we do with ulongs?
- 6. Do intensive performance testing.
- 7. Add Unit Testing comparing input and output to ensure bit-identical serialization and deserialization
