MediaCodec.CryptoInfo.Pattern
extends Object
Metadata describing an encryption pattern for the protected bytes in a subsample. An
encryption pattern consists of a repeating sequence of crypto blocks comprised of a
number of encrypted blocks followed by a number of unencrypted, or skipped, blocks.
Summary
Public constructors |
|---|
Pattern(int blocksToEncrypt, int blocksToSkip)
Construct a sample encryption pattern given the number of blocks to encrypt and skip
in the pattern.
|
Public methods |
|---|
int
|
getEncryptBlocks()
Return the number of blocks to encrypt in a sample encryption pattern.
|
int
|
getSkipBlocks()
Return the number of blocks to skip in a sample encryption pattern.
|
void
|
set(int blocksToEncrypt, int blocksToSkip)
Set the number of blocks to encrypt and skip in a sample encryption pattern.
