-// frame, if it was generated from a remote source. Either way, an
-// implementation should not present the frame before this point-in-time. This

-// for A/V synchronization purposes. NOTE: It is possible for this value to be

-// |video_frame->timestamp()| gives the presentation timestamp of the video

-// Because a source can start generating frames before a subscriber is added,
-// the first video frame delivered may not have timestamp equal to 0.
