- Method Detail
  - getName
```
String getName()
```
    Returns the name of the decoder.
    
    Returns:
    
    The name of the decoder.
  - dequeueInputBuffer
```
@Nullable
I dequeueInputBuffer()
              throws E extends DecoderException
```
    Dequeues the next input buffer to be filled and queued to the decoder.
    
    Returns:
    
    The input buffer, which will have been cleared, or null if a buffer isn't available.
    
    Throws:
    
    E - If a decoder error has occurred.
    
    E extends DecoderException
  - queueInputBuffer
```
void queueInputBuffer(I inputBuffer)
               throws E extends DecoderException
```
    Queues an input buffer to the decoder.
    
    Parameters:
    
    inputBuffer - The input buffer.
    
    Throws:
    
    E - If a decoder error has occurred.
    
    E extends DecoderException
  - dequeueOutputBuffer
```
@Nullable
O dequeueOutputBuffer()
               throws E extends DecoderException
```
    Dequeues the next output buffer from the decoder.
    
    Returns:
    
    The output buffer, or null if an output buffer isn't available.
    
    Throws:
    
    E - If a decoder error has occurred.
    
    E extends DecoderException
  - flush
```
void flush()
```
    Flushes the decoder. Ownership of dequeued input buffers is returned to the decoder. The caller is still responsible for releasing any dequeued output buffers.
  - release
```
void release()
```
    Releases the decoder. Must be called when the decoder is no longer needed.
