If your time stamp doesn't already have the host time field populated, you need to convert the sample time to host time using AudioDeviceTranslateTime(). From there, you can put the host time in a CVTimeStamp and use CVDisplayLinkTranslateTime to get to whichever video time base you want that the display link supports.

Does anyone on here know how to convert the sample time of a core audio unit into a CVTimeStamp (that i can then use to determine which frame to display in a video being played by core video)?

Just trying to sync audio and video. Nothing more.
