Profiling has shown that a significant amount of time was spent in VideoMediaSampleRenderer::purgeDecodedSampleQueue where we iterate the decoded samples queue to remove those that have expired. This queue is a priority queue using a CFArray as backend and isn't particularly optimised for our usage.
