Implement 2 new elements - splitmuxsink and splitmuxsrc. splitmuxsink is a bin which wraps a muxer and takes 1 video stream, plus audio/subtitle streams, and starts a new file whenever necessary to avoid overrunning a threshold of either bytes or time. New files are started at a keyframe, and corresponding audio and subtitle streams are split at packet boundaries to match video GOP timestamps. splitmuxsrc is a corresponding source element which handles the splitmux:// URL and plays back all component files, reconstructing the original elementary streams as it goes.
