Class Overview

Per buffer metadata includes an offset and size specifying the range of valid data in the associated codec (output) buffer.

Summary

Fields
public int flags Buffer flags associated with the buffer.
public int offset The start-offset of the data in the buffer.
public long presentationTimeUs The presentation timestamp in microseconds for the buffer.
public int size The amount of data (in bytes) in the buffer.
Public Constructors
MediaCodec.BufferInfo()
Public Methods
void set(int newOffset, int newSize, long newTimeUs, int newFlags)
Update the buffer metadata information.

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 Constructors

public MediaCodec.BufferInfo ()

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