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 SimpleMetadataDecoderParameters: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.
