Field Detail

- 

iv

@Nullable
public byte[] iv

Deprecated.

The 16 byte initialization vector. If the initialization vector of the content is shorter than 16 bytes, 0 byte padding is appended to extend the vector to the required 16 byte length. See Also:MediaCodec.CryptoInfo.iv

- 

key

@Nullable
public byte[] key

Deprecated.

The 16 byte key id. See Also:MediaCodec.CryptoInfo.key

- 

mode

public @com.google.android.exoplayer2.C.CryptoMode int mode

Deprecated.

The type of encryption that has been applied. Must be one of the C.CryptoMode values. See Also:MediaCodec.CryptoInfo.mode

- 

numBytesOfClearData

@Nullable
public int[] numBytesOfClearData

Deprecated.

The number of leading unencrypted bytes in each sub-sample. If null, all bytes are treated as encrypted and numBytesOfEncryptedData must be specified. See Also:MediaCodec.CryptoInfo.numBytesOfClearData

- 

numBytesOfEncryptedData

@Nullable
public int[] numBytesOfEncryptedData

Deprecated.

The number of trailing encrypted bytes in each sub-sample. If null, all bytes are treated as clear and numBytesOfClearData must be specified. See Also:MediaCodec.CryptoInfo.numBytesOfEncryptedData

- 

numSubSamples

public int numSubSamples

Deprecated.

The number of subSamples that make up the buffer's contents. See Also:MediaCodec.CryptoInfo.numSubSamples

- 

encryptedBlocks

public int encryptedBlocks

Deprecated. See Also:MediaCodec.CryptoInfo.Pattern

- 

clearBlocks

public int clearBlocks

Deprecated. See Also:MediaCodec.CryptoInfo.Pattern

Constructor Detail

- 

CryptoInfo

public CryptoInfo()

Deprecated.

set

public void set​(int numSubSamples,
                int[] numBytesOfClearData,
                int[] numBytesOfEncryptedData,
                byte[] key,
                byte[] iv,
                @com.google.android.exoplayer2.C.CryptoMode int mode,
                int encryptedBlocks,
                int clearBlocks)

Deprecated. See Also:MediaCodec.CryptoInfo.set(int, int[], int[], byte[], byte[], int)

- 

getFrameworkCryptoInfo

public[MediaCodec.CryptoInfo](https://developer.android.com/reference/android/media/MediaCodec.CryptoInfo.html "class or interface in android.media")getFrameworkCryptoInfo()

Deprecated.

Returns an equivalent MediaCodec.CryptoInfo instance.

Successive calls to this method on a single CryptoInfo will return the same instance. Changes to the CryptoInfo will be reflected in the returned object. The return object should not be modified directly.

Returns:The equivalent MediaCodec.CryptoInfo instance.

- 

increaseClearDataFirstSubSampleBy

public void increaseClearDataFirstSubSampleBy​(int count)

Deprecated.

Increases the number of clear data for the first sub sample by count.

If count is 0, this method is a no-op. Otherwise, it adds count to numBytesOfClearData[0].

If numBytesOfClearData is null (which is permitted), this method will instantiate it to a new int[1].

Parameters:count - The number of bytes to be added to the first subSample of numBytesOfClearData.
