A conformant clock component, designed to be compatible with a standard clock component. It currently supports 6 output clock ports.

PortIndexNotes
80 81 82 83 84 85OMX_IndexParamPortDefinition The port definition can be used to connect each port to a clock port on another component.
OMX_IndexParamOtherPortFormat This param is used to confirm that this port supports clock messages.
OMX_IndexConfigTimeScale We support setting the timescale to achieve slow motion, fast forward, paused, and rewind playback. To achieve rewind and fast forward, note the extra playmode config in the read_media.
OMX_IndexConfigTimeClockState Query / set current clock state.
OMX_IndexConfigTimeCurrentWallTime Query current wall time.
OMX_IndexConfigTimeActiveRefClock Query / set the active reference clock.
OMX_IndexConfigTimeCurrentMediaTime Query current media time.
OMX_IndexConfigTimeClientStartTime Set the start time of a client stream, typically used by a tunneled component.
OMX_IndexConfigTimeInvalidStartTime Notification that a client will not be sending a start time.
OMX_IndexConfigTimeCurrentAudioReference Set the instantaneous audio reference clock value. Time values received are filtered to remove jitter.
OMX_IndexConfigTimeCurrentVideoReference Set the instantaneous video reference clock value.
OMX_IndexConfigTimeMediaTimeRequest Make a media time request.
OMX_IndexConfigBrcmClockMissCount Return a count of the number of media time requests that were missed, because they arrived too late (after the requested time).
 OMX_IndexConfigSingleStep Advance a paused clock through the next set of requested media times.
OMX_IndexConfigClockAdjustment Get the total amount that the clock media time has shifted due to clock reference time updates since the clock started running.
OMX_IndexConfigLatencyTarget Query / set the filter values used when tracking offset between media time and reference clock source by applying small changes to media time speed.
