Description
Compositors require video frames to be submitted in a specific time window to be rendered at the correct vsync signal. This introduces requirements for the video sink element to adjust to the pipeline clock and to the display clock which may drift unrelated to the pipeline clock.
Furthermore, some existing video sinks are targeting UI frameworks and are not directly related to a specific compositor and thus may have unrelated refresh cycles.
This talk summarizes the general issue and highlights the problems with some existing video sinks.
