• content generation for mpeg dash for Dash.if player

  9 mai 2014, par Pavan K

  Could anyone please tell me how to encode content to be player with the dash.if player on the chrome browser

  https://github.com/Dash-Industry-Forum/dash.js — This is the player in question.

  I tried mp4box and ffmpeg to create content but The samples pointed in the examples work well but I cant make my own videos to work with the dash player.

  I used all possible options on the mp4box with no luck [ from http://gpac.wp.mines-telecom.fr/2011/02/02/mp4box-fragmentation-segmentation-splitting-and-interleaving/ ]
