  - needsReconfiguration
```
public boolean needsReconfiguration()
```
    Description copied from interface: MediaCodecAdapter
    
    Whether the adapter needs to be reconfigured before it is used.
    
    Specified by:
    
    needsReconfiguration in interface MediaCodecAdapter
  - dequeueInputBufferIndex
```
public int dequeueInputBufferIndex()
```
    Description copied from interface: MediaCodecAdapter
    
    Returns the next available input buffer index from the underlying MediaCodec or MediaCodec.INFO_TRY_AGAIN_LATER if no such buffer exists.
    
    Specified by:
    
    dequeueInputBufferIndex in interface MediaCodecAdapter
  - dequeueOutputBufferIndex
```
public int dequeueOutputBufferIndex(MediaCodec.BufferInfo bufferInfo)
```
    Description copied from interface: MediaCodecAdapter
    
    Returns the next available output buffer index from the underlying MediaCodec. If the next available output is a MediaFormat change, it will return MediaCodec.INFO_OUTPUT_FORMAT_CHANGED and you should call MediaCodecAdapter.getOutputFormat() to get the format. If there is no available output, this method will return MediaCodec.INFO_TRY_AGAIN_LATER.
    
    Specified by:
    
    dequeueOutputBufferIndex in interface MediaCodecAdapter
  - getOutputFormat
```
public MediaFormat getOutputFormat()
```
    Description copied from interface: MediaCodecAdapter
    
    Gets the MediaFormat that was output from the MediaCodec.
    Call this method if a previous call to MediaCodecAdapter.dequeueOutputBufferIndex(android.media.MediaCodec.BufferInfo) returned MediaCodec.INFO_OUTPUT_FORMAT_CHANGED.
    
    Specified by:
    
    getOutputFormat in interface MediaCodecAdapter

```
    Description copied from interface: MediaCodecAdapter
    
    Submit an input buffer for decoding.
    The index must be an input buffer index that has been obtained from a previous call to MediaCodecAdapter.dequeueInputBufferIndex().
    
    Specified by:
    
    queueInputBuffer in interface MediaCodecAdapter

```
    Description copied from interface: MediaCodecAdapter
    
    Submit an input buffer that is potentially encrypted for decoding.
    The index must be an input buffer index that has been obtained from a previous call to MediaCodecAdapter.dequeueInputBufferIndex().
    This method behaves like MediaCodec.queueSecureInputBuffer(int, int, android.media.MediaCodec.CryptoInfo, long, int), with the difference that info is of type CryptoInfo and not MediaCodec.CryptoInfo.
    
    Specified by:

  - releaseOutputBuffer
```
public void releaseOutputBuffer(int index,
                                boolean render)
```
    Description copied from interface: MediaCodecAdapter
    
    Returns the buffer to the MediaCodec. If the MediaCodec was configured with an output surface, setting render to true will first send the buffer to the output surface. The surface will release the buffer back to the codec once it is no longer used/displayed.
    
    Specified by:

```
    Description copied from interface: MediaCodecAdapter
    
    Updates the output buffer's surface timestamp and sends it to the MediaCodec to render it on the output surface. If the MediaCodec is not configured with an output surface, this call will simply return the buffer to the MediaCodec.
