+// is associated with a particular frame. A typical sequence of usage is as follows:
+//
+// a) OMX_SetConfig associates the config with the next input buffer sent in OMX_EmptyThisBuffer
+//    (input A);
+// b) The component sends OMX_EventConfigUpdate to notify the client that there is a config
+//    update  on the output port that is associated with the next output buffer that's about to
+//    be sent via FillBufferDone callback (output A);
+// c) The client, upon receiving the OMX_EventConfigUpdate, calls OMX_GetConfig to retrieve
+//    the config and associates it with output A.
+//
+// All config updates will be retrieved in the order reported, and the client is required to
+// call OMX_GetConfig for each OMX_EventConfigUpdate for this config. Note that the order of
+// OMX_EventConfigUpdate relative to FillBufferDone callback determines which output frame
+// the config should be associated with, the actual OMX_GetConfig for the config could happen
+// before or after the component calls the FillBufferDone callback.
+//
+// Depending on the video codec type (in particular, whether the codec uses in-band or out-of-
+// band HDR10+ metadata), the component shall behave as detailed below:
+//
+// VIDEO DECODERS:
+// 1) If the codec utilizes out-of-band HDR10+ metadata, the decoder must support the sequence
+//    a) ~ c) outlined above;
+// 2) If the codec utilizes in-band HDR10+ metadata, OMX_SetConfig for this config should be
+//    ignored (as the metadata is embedded in the input buffer), while the notification and
+//    retrieval of the config on the output as outlined in b) & c) must be supported.
+//
+// VIDEO ENCODERS:
+// 1) If the codec utilizes out-of-band HDR10+ metadata, the decoder must support the sequence
+//    a) ~ c) outlined above;
+// 2) If the codec utilizes in-band HDR10+ metadata, OMX_SetConfig for this config outlined in
+//    a) must be supported. The notification as outlined in b) must not be sent, and the
+//    retrieval of the config via OMX_GetConfig should be ignored (as the metadata is embedded
