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.

Pattern

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

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

Parameters
