set

fun set(

    newSize: Int, 
    newTimeUs: Long, 
    newFlags: Int
): Unit

Update the buffer metadata information.

flags

var flags: Int

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

offset

var offset: Int

The start-offset of the data in the buffer.

presentationTimeUs

var presentationTimeUs: Long

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

var size: Int

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.
