Note: You need to download the playlist (m3u8) first e.g. from http://p.events-delivery.apple.com.edgesuite.net/15pijbnaefvpoijbaefvpihb06/vod2/8500/8500_vod.m3u8

This URL is taken out the main playlist linked in the source code of Apple's WWDC 2015 website. Here is a link to it (contains also lower qualities if you prefer them):
