This describes encryption info for a packet.
This contains frame-specific info for how to decrypt the packet before passing it to the decoder.
The size of this struct is not part of the public ABI.

| uint32_t AVEncryptionInfo::scheme |
The fourcc encryption scheme.

| uint32_t AVEncryptionInfo::crypt_byte_block |
Only used for pattern encryption.
This is the number of 16-byte blocks that are encrypted.

| uint32_t AVEncryptionInfo::skip_byte_block |
Only used for pattern encryption.
This is the number of 16-byte blocks that are clear.

| uint8_t* AVEncryptionInfo::key_id |
The ID of the key used to encrypt the packet.
This should always be 16 bytes long, but may be changed in the future.

| uint8_t* AVEncryptionInfo::iv |
The initialization vector.
This may have been zero-filled to be the correct block size. This should always be 16 bytes long, but may be changed in the future.

If there are no subsamples, then the whole sample is encrypted.
