* earlier than the media time specified. In this case the client specifies
* an offset which is equal to the difference between wall time corresponding
* to the requested media time and the wall time when it will be
* fulfilled.
*
* A client component may uses these requests and the OMX_TIME_MEDIATIMETYPE to
* time events according to timestamps. If a client must perform an operation O at
* a time T (e.g. deliver a video frame at its corresponding timestamp), it makes a
* media time request at T (perhaps specifying an offset to ensure the request fulfillment
* is a little early). When the clock component passes the resulting OMX_TIME_MEDIATIMETYPE

* to a client component (via the client port) according to the corresponding media
* time request sent by the client. The Clock Component should time the emission to occur
* when the requested timestamp matches the Clock Component's media time but also the
* prescribed offset early.
*
* Upon scale changes the clock component clears the nClientPrivate data, sends the current
* media time and sets the nScale to the new scale via the client port. It emits a
* OMX_TIME_MEDIATIMETYPE to all clients independent of any requests. This allows clients to
* alter processing to accomodate scaling. For instance a video component might skip inter-frames
* in the case of extreme fastforward. Likewise an audio component might add or remove samples
* from an audio frame to scale audio data.
*
* It is expected that some clock components may not be able to fulfill requests
* at exactly the prescribed time. This is acceptable so long as the request is
* fulfilled at least as early as described and not later. This structure provides
* fields the client may use to wait for the remaining time.
*
* The client may use either the nOffset or nWallTimeAtMedia fields to determine the
* wall time until the nMediaTimestamp actually occurs. In the latter case the
* client can get a more accurate value for offset by getting the current wall
* from the cloc component and subtracting it from nWallTimeAtMedia.
