flags Buffer flags associated with the buffer. |
public int |
offset The start-offset of the data in the buffer. |

presentationTimeUs The presentation timestamp in microseconds for the buffer. |
public int |
size The amount of data (in bytes) in the buffer. |

int flags
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.
long presentationTimeUs
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.
int size
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.
void set (int newOffset, int newSize, long newTimeUs, int newFlags)
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 . |
