So as far as I understand it, there is no way (yet) to play live video streams using HTML5 video on your Apple device and have 1-1.5 second latency or less. The only streaming protocol Apple seems to support is HLS and it involves dividing video to chunks, downloading them one by one, and having downloaded enough pieces (3 by default) start playing it. If each of these pieces is 3seconds long, then you are looking at 9-10 second latency. Reducing the length of the piece causes constant disruption when streaming and reducing bitrate of the video doesn't seem to reduce the said marker.
Is there any other viable solution for streaming truly live video using HTML5 on Apple mobile devices?
