- Method Detail
  - isInitialized

```
 void initialize()
```
  - getDurationUs
```
 long getDurationUs()
```
    Returns the video total duration in microseconds.
  - getPositionUs
```
 long getPositionUs()
```
    Returns the current read position, between 0 and duration.
  - canReadTrack
```
 boolean canReadTrack(@NonNull() TrackType type)
```
    Returns true if we can read the given track at this point.If true if returned, source should expect a readTrack call.
    
    Parameters:
    
    type - track type
  - isDrained
```
 boolean isDrained()
```
    When this source has been totally read, it can return true here tonotify an end of input stream.
  - seekTo
```
 long seekTo(long desiredPositionUs)
```
    Moves all selected tracks to the specified presentation time.The timestamp should be between 0 and getDurationUs.The actual timestamp might differ from the desired one because ofseeking constraints (e.g. seek to sync frames). It will typically be smallerbecause we use SEEK_TO_PREVIOUS_SYNC inthe default source.
    
    Parameters:
    
    desiredPositionUs - requested timestamp
