## Fields

### flags

Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int flags
```

Buffer flags associated with the buffer. A combination of
`https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_KEY_FRAME` and `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_END_OF_STREAM`.

Encoded buffers that are key frames are marked with
`https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_KEY_FRAME`.

The last output buffer corresponding to the input buffer
marked with `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_END_OF_STREAM` will also be marked
with `https://developer.android.com/reference/android/media/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 the following:

- `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_SYNC_FRAME`
- `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_KEY_FRAME`
- `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_CODEC_CONFIG`
- `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_END_OF_STREAM`
- `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_PARTIAL_FRAME`
- `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_DECODE_ONLY`

### offset

Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int offset
```

The start-offset of the data in the buffer.

<br />

### presentationTimeUs

Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
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.

<br />

### size

Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
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.

<br />

## Public constructors

### BufferInfo

```
public BufferInfo ()
```

<br />

<br />

## Public methods

### set

Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

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

Update the buffer metadata information.

<br />

| Parameters ||
|---|---|
| `newOffset` | `int`: the start-offset of the data in the buffer. <br /> |
| `newSize` | `int`: the amount of data (in bytes) in the buffer. <br /> |
| `newTimeUs` | `long`: the presentation timestamp in microseconds. <br /> |
| `newFlags` | `int`: buffer flags associated with the buffer. This should be a combination of `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_KEY_FRAME` and `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_END_OF_STREAM`. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_SYNC_FRAME` - `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_KEY_FRAME` - `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_CODEC_CONFIG` - `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_END_OF_STREAM` - `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_PARTIAL_FRAME` - `https://developer.android.com/reference/android/media/MediaCodec#BUFFER_FLAG_DECODE_ONLY` |
