I should also mention that there is some uncertainty about the precise meaning of currentTime - particularly when you have a media pipeline where the frame/sample coming out of the end may be 0.5s further along the media timeline than the ones entering the media pipeline. Some people think currentTime reflects what is coming out of the display/speakers/headphones. Some people think it should reflect the time were video and graphics are composited as this is easy to test and suits apps trying to sync graphics to video or audio. Simple implementations may re-use a time available in a media decoder.
