protected Metadata decode(MetadataInputBuffer inputBuffer,
                          ByteBuffer buffer)
```
    Description copied from class: SimpleMetadataDecoder
    
    Called by SimpleMetadataDecoder.decode(MetadataInputBuffer) after input buffer validation has been performed, except in the case that Buffer.isDecodeOnly() is true.
    
    Specified by:
    
    decode in class SimpleMetadataDecoder
    
    Parameters:
    
    inputBuffer - The input buffer to decode.
    
    buffer - The input buffer's data buffer, for convenience. Validation by SimpleMetadataDecoder.decode(com.google.android.exoplayer2.metadata.MetadataInputBuffer) guarantees that ByteBuffer.hasArray(), Buffer.position() and ByteBuffer.arrayOffset() are true, 0 and 0 respectively.
    
    Returns:
    
    The decoded metadata object, or null if the metadata could not be decoded.
