Struct AVEncryptionInfo

#[repr(C)]
pub struct AVEncryptionInfo {
    pub scheme: u32,
    pub crypt_byte_block: u32,
    pub skip_byte_block: u32,
    pub key_id: *mut u8,
    pub key_id_size: u32,
    pub iv: *mut u8,
    pub iv_size: u32,
    pub subsamples: *mut AVSubsampleEncryptionInfo,
    pub subsample_count: u32,
}

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.

Fields

scheme: u32

The fourcc encryption scheme, in big-endian byte order.

crypt_byte_block: u32

Only used for pattern encryption. This is the number of 16-byte blocks that are encrypted.

skip_byte_block: u32

Only used for pattern encryption. This is the number of 16-byte blocks that are clear.

key_id: *mut u8

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: u32

iv: *mut u8

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: u32

subsamples: *mut AVSubsampleEncryptionInfo

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.

subsample_count: u32
