...where A/V is at the demuxer currently. Due to queueing this could be
different to where it is further downstream, and as subtitle streams are sparse
the filler newsegment event can run ahead of the A/V data and reach
inputselector earlier. Might be possible prevent this running ahead inside
multiqueue though, it already syncs the newsegment events but probably not good
enough yet.
