so far understand it, there no way (yet) play live video streams using html5 video on apple device , have 1-1.5 second latency or less. streaming protocol apple seems support hls , involves dividing video chunks, downloading them 1 one, , having downloaded enough pieces ( 3 default) start playing it. if each of these pieces 3 seconds long, looking @ 9-10 second latency. reducing length of piece causes constant disruption when streaming , reducing bitrate of video doesn't seem reduce said marker. is there other viable solution streaming truly live video using html5 on apple mobile devices? if anybody's wondering - there still hacky workaround avoid using hls @ all. you can convert video stream sequence of images in mpeg1 format (using ffmpeg example) , download them @ client side using javascript library , use canvas element display them. can achieved using jsmpeg , streaming-server code runs on node.js i able 30 fps 540x320 resolution 150ms lat...
