The serialized blob. See Remarks.
Remarks
The following schema describes the serialized blob that is returned from this method:
- GUID – the content protection system GUID.
- DWORD – the stream count.
- DWORD – next stream ID.
- DWORD – next stream’s binary data size.
- BYTE* - next stream’s binary data.
- Repeat steps 3, 4, and 5 for each stream.
IPropertySet may contain any of the following values but must contain at least one of them.
- The property N, where N is replaced by the base-10 stream number being decrypted, set to the PlayReady Object corresponding to that stream.
- The property set to a PlayReady Object that will be used for any stream number that was not set using N as described above.
