Why doesn't my video play in firefox?


Using firefox and trying to watch a video using the jwplayer you get a file not found error. There must've been an update that screwed with firefox because every other browser works just fine.

Here is a page with the player on it http://ballislife.com/donovan-mitchell-shuts-down-brooklyn-under-armour-elite-24-game-top-10-plays/

Wrong MIME type. The amazonaws server is serving the MP4 with a MIME type of "text/plain" instead of "video/mp4."

I see Firefox on a Mac is able to play this video, but the entire video had to load before playback started. How was this video encoded? Did you enable the Web optimized (or fast start) option?

Firefox on a Mac is using Flash, rather than HTML5, so the MIME type issue doesn't affect it. But yeah, if it has to be completely downloaded before playing, the faststart option hasn't been used for encoding, so it won't stream.

Thanks MisterNeutron, that was the issue. Todd, I replaced the videos by the time you checked it. Thanks.

Whenever I see amazonaws as the content server, the MIME type is the first thing I look at. They get it wrong every friggin' time. It really is inexcusable.
