Created attachment 281391 [details] Testcase The following code automatically plays a video for me on iPhone / iOS 10. <video preload="auto" autoplay webkit-playsinline src="http://p.events-delivery.apple.com.edgesuite.net/1603kjbnadcpjhbasdvpjbasdvpjb/m3u8/hls_vod11_mvp.m3u8" controls poster="http://images.apple.com/apple-events/march-2016/video/poster_medium_2x.jpg"></video> I believe only muted videos or videos without audio tracks should auto play.
