+ *   the same position of frames originating from different streams must be
+ *   established externally;
+ *
+ * - layout mask, which gives a label to each channel, thus allowing to
+ *   match channels between streams of different layouts.
+ *
+ * Both representations are agnostic of the direction of audio transfer. Also,
+ * by construction, the number of bits set to '1' in the mask indicates the
+ * number of channels in the audio frame. A channel mask per se only defines the
+ * presence or absence of a channel, not the order. Please see 'INTERLEAVE_*'
+ * constants for the platform convention of order.

+     *     the latter is augmented with a suffix, e.g. "audio/eac3-joc" for the
+     *     JOC extension of EAC-3.
+     *   - If it's a proprietary format, a "vnd." prefix is added, similar to
+     *     IANA rules, e.g. "audio/vnd.dolby.truehd".
+     *   - Otherwise, "x-" prefix is added, e.g. "audio/x-iec61937".
+     *   - All MIME types not found in the IANA formats list have an associated
+     *     comment.
+     *
+     * For PCM encapsulations with a known bitstream format, the latter
+     * is added to the encapsulation encoding as a suffix, after a "+" char.
+     * For example, an IEC61937 encapsulation of AC3 has the following
+     * representation:
+     *   type = NON_PCM,
+     *   pcm = PcmType.INT_16_BIT,
