This describes info used to initialize an encryption key system.
The size of this struct is not part of the public ABI.
Definition at line 88 of file encryption_info.h.
| uint8_t* AVEncryptionInitInfo::system_id |
A unique identifier for the key system this is for, can be NULL if it is not known.
This should always be 16 bytes, but may change in the future.

| uint8_t** AVEncryptionInitInfo::key_ids |
An array of key IDs this initialization data is for.
All IDs are the same length. Can be NULL if there are no known key IDs.

| uint8_t* AVEncryptionInitInfo::data |
Key-system specific initialization data.
This data is copied directly from the file and the format depends on the specific key system. This can be NULL if there is no initialization data; in that case, there will be at least one key ID.
