Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Fields

public int flags

Added in API level 16

Buffer flags associated with the buffer. A combination of BUFFER_FLAG_KEY_FRAME and BUFFER_FLAG_END_OF_STREAM.

Encoded buffers that are key frames are marked with BUFFER_FLAG_KEY_FRAME.

The last output buffer corresponding to the input buffer marked with BUFFER_FLAG_END_OF_STREAM will also be marked with BUFFER_FLAG_END_OF_STREAM. In some cases this could be an empty buffer, whose sole purpose is to carry the end-of-stream marker.

public int offset

Added in API level 16

The start-offset of the data in the buffer.

public long presentationTimeUs

Added in API level 16

The presentation timestamp in microseconds for the buffer. This is derived from the presentation timestamp passed in with the corresponding input buffer. This should be ignored for a 0-sized buffer.

public int size

Added in API level 16

The amount of data (in bytes) in the buffer. If this is 0, the buffer has no data in it and can be discarded. The only use of a 0-size buffer is to carry the end-of-stream marker.

Public Methods

public void set (int newOffset, int newSize, long newTimeUs, int newFlags)

Added in API level 16

Update the buffer metadata information.

Parameters

newOffset	the start-offset of the data in the buffer.
newSize	the amount of data (in bytes) in the buffer.
newTimeUs	the presentation timestamp in microseconds.
newFlags	buffer flags associated with the buffer. This should be a combination of `BUFFER_FLAG_KEY_FRAME` and `BUFFER_FLAG_END_OF_STREAM`.
