MediaCodec.CryptoInfo.Pattern


public static final class MediaCodec.CryptoInfo.Pattern
extends Object

java.lang.Object
   ↳ android.media.MediaCodec.CryptoInfo.Pattern


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.

Inherited methods

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

public int getSkipBlocks ()

Return the number of blocks to skip in a sample encryption pattern.

Returns
int

set

Added in API level 24
public void set (int blocksToEncrypt, 
                int blocksToSkip)

Set the number of blocks to encrypt and skip in a sample encryption pattern. If both parameters are zero, pattern encryption is inoperative.

Parameters
blocksToEncrypt int

blocksToSkip int
