   ↳ 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

MediaCodec.CryptoInfo.Pattern(int blocksToEncrypt, int blocksToSkip)

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.
