  * If you add a codec ID to this list, add it so that
  * 1. no value of a existing codec ID changes (that would break ABI),
- * 2. it is as close as possible to similar codecs.
+ * 2. Give it a value which when taken as ASCII is recognized uniquely by a human as this specific codec.
+ *    This ensures that 2 forks can independantly add CodecIDs without producing conflicts.
