AVEncryptionInfo

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.

Variables

crypt_byte_block uint crypt_byte_block;: Only used for pattern encryption. This is the number of 16-byte blocks that are encrypted.
iv ubyte* 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.
iv_size uint iv_size;: Undocumented in source.
key_id ubyte* 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.
key_id_size uint key_id_size;: Undocumented in source.
scheme uint scheme;: The fourcc encryption scheme, in big-endian byte order.
skip_byte_block uint skip_byte_block;: Only used for pattern encryption. This is the number of 16-byte blocks that are clear.
subsample_count uint subsample_count;: Undocumented in source.
subsamples AVSubsampleEncryptionInfo* subsamples;: An array of subsample encryption info specifying how parts of the sample are encrypted. If there are no subsamples, then the whole sample is encrypted.
