Fields
flags
public int flags
Buffer flags associated with the buffer. A combination of
MediaCodec.BUFFER_FLAG_KEY_FRAME
and MediaCodec.BUFFER_FLAG_END_OF_STREAM
.
Encoded buffers that are key frames are marked with
MediaCodec.BUFFER_FLAG_KEY_FRAME
.
The last output buffer corresponding to the input buffer
marked with MediaCodec.BUFFER_FLAG_END_OF_STREAM
will also be marked
with MediaCodec.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.
Value is either 0
or a combination of MediaCodec.BUFFER_FLAG_SYNC_FRAME
, MediaCodec.BUFFER_FLAG_KEY_FRAME
, MediaCodec.BUFFER_FLAG_CODEC_CONFIG
, MediaCodec.BUFFER_FLAG_END_OF_STREAM
, MediaCodec.BUFFER_FLAG_PARTIAL_FRAME
, android.media.MediaCodec.BUFFER_FLAG_MUXER_DATA, and MediaCodec.BUFFER_FLAG_DECODE_ONLY
presentationTimeUs
public 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.
size
public 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.

set
public 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 MediaCodec.BUFFER_FLAG_KEY_FRAME and
MediaCodec.BUFFER_FLAG_END_OF_STREAM .
Value is either 0 or a combination of MediaCodec.BUFFER_FLAG_SYNC_FRAME , MediaCodec.BUFFER_FLAG_KEY_FRAME , MediaCodec.BUFFER_FLAG_CODEC_CONFIG , MediaCodec.BUFFER_FLAG_END_OF_STREAM , MediaCodec.BUFFER_FLAG_PARTIAL_FRAME , android.media.MediaCodec.BUFFER_FLAG_MUXER_DATA, and MediaCodec.BUFFER_FLAG_DECODE_ONLY |
