Video file .ogv plays locally in Firefox, but not from server
问题 I'm not having any problems playing this video in Chrome, Safari or Opera. When I try to play it in Firefox, I get a grey box with no video. Here is my code: <video width="640" height="360" autobuffer controls preload="auto" > <source src="fracWelDay3.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'> <source src="fracWelDay3.webm" type='video/webm; codecs="vp8, vorbis"'> <source src="fracWelDay3.ogv" type='video/ogg; codecs="theora, vorbis"'> Your browser does not support the video tag.
