      * Codec format changed.
      *
+     * onCodecFormatChanged returns an AudioMetadata object in read-only ByteString format.
+     * It represents the most recent codec format decoded by a HW audio decoder.
+     *
+     * Codec format is an optional message from HW audio decoders. It serves to
+     * notify the application about the codec format and audio objects contained
+     * within the compressed audio stream for control, informational,
+     * and display purposes.
+     *
+     * audioMetadata ByteString is convertible to an AudioMetadata object through
+     * both a C++ and a C API present in Metadata.h [1], or through a Java API present
+     * in AudioMetadata.java [2].
+     *
+     * The ByteString format is a stable format used for parcelling (marshalling) across
+     * JNI, AIDL, and HIDL interfaces.  The test for R compatibility for native marshalling
+     * is TEST(metadata_tests, compatibility_R) [3].  The test for R compatibility for JNI
+     * marshalling is android.media.cts.AudioMetadataTest#testCompatibilityR [4].
+     *
+     * R (audio HAL 6.0) defined keys are as follows [2]:
+     * "bitrate", int32
+     * "channel-mask", int32
+     * "mime", string
+     * "sample-rate", int32
+     * "bit-width", int32
+     * "has-atmos", int32
+     * "audio-encoding", int32
+     *
+     * Parceling Format:
+     * All values are native endian order. [1]
+     *
+     * using type_size_t = uint32_t;
+     * using index_size_t = uint32_t;
+     * using datum_size_t = uint32_t;
+     *
+     * Permitted type indexes are
+     * TYPE_NONE = 0, // Reserved
+     * TYPE_INT32 = 1,
+     * TYPE_INT64 = 2,
+     * TYPE_FLOAT = 3,
+     * TYPE_DOUBLE = 4,
+     * TYPE_STRING = 5,
+     * TYPE_DATA = 6,  // A data table of <String, Datum>
+     *
+     * Datum = {
+     *           (type_size_t)  Type (the type index from type_as_value<T>.)
+     *           (datum_size_t) Size (size of the Payload)
+     *           (byte string)  Payload<Type>
+     *         }
+     *
+     * The data is specified in native endian order.
+     * Since the size of the Payload is always present, unknown types may be skipped.
+     *
+     * Payload<Fixed-size Primitive_Value>
+     * [ sizeof(Primitive_Value) in raw bytes ]
+     *
+     * Example of Payload<Int32> of 123:
+     * Payload<Int32>
+     * [ value of 123                   ] =  0x7b 0x00 0x00 0x00       123
+     *
+     * Payload<String>
+     * [ (index_size_t) length, not including zero terminator.]
+     * [ (length) raw bytes ]
+     *
+     * Example of Payload<String> of std::string("hi"):
+     * [ (index_size_t) length          ] = 0x02 0x00 0x00 0x00        2 strlen("hi")
+     * [ raw bytes "hi"                 ] = 0x68 0x69                  "hi"
