Method Detail

• decode

  @Nullable
  public final Metadata decode​(MetadataInputBuffer inputBuffer)

  Description copied from interface: MetadataDecoder
  Decodes a Metadata element from the provided input buffer.

  Respects Buffer.limit() of inputBuffer.data, but assumes Buffer.position() and ByteBuffer.arrayOffset() are both zero and ByteBuffer.hasArray() is true.

  Specified by:

  decode in interface MetadataDecoder

  Parameters:

  inputBuffer - The input buffer to decode.

  Returns:

  The decoded metadata object, or null if the metadata could not be decoded or if Buffer.isDecodeOnly() was set on the input buffer.

• decode

  @Nullable
  protected abstract Metadata decode​(MetadataInputBuffer inputBuffer,
                                     ByteBuffer buffer)

  Called by decode(MetadataInputBuffer) after input buffer validation has been performed, except in the case that Buffer.isDecodeOnly() is true.

  Parameters:

  inputBuffer - The input buffer to decode.

  buffer - The input buffer's data buffer, for convenience. Validation by 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.
