## Public methods

### describeContents

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

```
public int describeContents ()
```

Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of `https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)`,
the return value of this method must include the
`https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` bit.

<br />

| Returns ||
|---|---|
| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or - `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` |

### getFormat

```
public MediaFormat getFormat ()
```

Gets the `https://developer.android.com/reference/android/media/MediaFormat` of the track. If the format is
unknown or could not be determined, null is returned.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/media/MediaFormat` | <br /> |
