-// type is used to build AIDL files in a way that they can be used across

+     * 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].
+     *

+     * "bitrate", int32
+     * "channel-mask", int32

+// The tests in this file are intended to be run manually, to allow testing of whether
+// keyblob upgrade works correctly.  The manual procedure is roughly:
+//
+// 1) Run the "*Before*" subset of these tests with the `--keyblob_dir <dir>` command-line argument
+//    so that keyblobs are saved to a directory on the device:
+//
+//      VtsAidlKeyMintTargetTest --gtest_filter="*KeyBlobUpgradeTest*Before*" \
+//                               --keyblob_dir /data/local/tmp/keymint-blobs
+//
+//    All tests should pass, and the `UpgradeKeyBlobs` test should indicate that no keyblob
+//    upgrades were needed.
+//
+// 2) Copy the generated keyblobs off the device into a safe place.
+//
+//      adb pull /data/local/tmp/keymint-blobs
+//
+// 3) Upgrade the device to a new version.
+//
+// 4) Push the saved keyblobs back onto the upgraded device.
+//
+//      adb push keymint-blobs /data/local/tmp/keymint-blobs
+//
+// 5) Run the "*After*" subset of these tests with the `--keyblob_dir <dir>` command-line argument
+//    pointing to the directory with the keyblobs:
+//
+//      VtsAidlKeyMintTargetTest --gtest_filter="*KeyBlobUpgradeTest*After*" \
+//                               --keyblob_dir /data/local/tmp/keymint-blobs
+//
+//    (Note that this skips the `CreateKeyBlobs` test, which would otherwise replace the saved
+//    keyblobs with freshly generated ones.).
+//
+//    All tests should pass, and the `UpgradeKeyBlobs` test should have output that matches whether
+//    upgrade was expected or not.
