Hi there, After a great satisfaction with the computers I realized I'm having problems visualizing a pseudo live generated by MP4Box on devices such android, iOS and ps4. the streming work fine with windows explorer, osx firefox chome and safari and on Ubuntu

For my test i use a video already encoded of Simpsons http://www.h264info.com/clips.html,

The MP4Box command line that generate the manifest is: sudo MP4Box -dash-live 1000 -frag 1000 -profile live -subdur 1000 -mpd-refresh 1000 -time-shift 3 -bs-switching no -segment-name output-seg -out manifest.mpd simp.mp4#video audio.m4a

THE MANIFEST:

<?xml version="1.0"?>

Is there any specification that I ignore to even visualize on these devices? Thanks! Gianmaria

I think this is the answer: https://github.com/Dash-Industry-Forum/dash.js/issues/2121 sorry for this stupid question, but anybody know something about ps4 compatibility? And also safari is problematic or any other news about?
