Abstract
Methods, systems, and computer-readable media for real-time video streaming with latency control are disclosed. Using a media streaming system, a current frame of a video input is acquired from an input pipeline. The current frame is associated with a timestamp. A mapped timestamp associated with the current frame is determined. The mapped timestamp represents the timestamp mapped to a clock associated with the media streaming system. Based at least in part on a comparison between the mapped timestamp and a deadline for frame output, the current frame is either transmitted to an output pipeline according to the deadline, held for evaluation against one or more subsequent deadlines, or discarded.
