h.264 videos that played in Firefox 34 won't play in Firefox 35.0

We host a ton of h.264 videos in the mp4 container displayed through JW Player. We had zero problems with Firefox 34 and earlier playing these videos, the video is H.264 and the audio is AAC, the whole thing is around 500 kbit/s.

They play fine on Firefox 34, Chrome and IE but after updating to Firefox 35.0 we get an error: "Error loading media: File could not be played".

We have found a fix to get them to work in the about:config, switching "media.fragmented-mp4.enabled" to false OR switching "media.fragmented-mp4.exposed" to false will allow our videos to play. Single file mp4's will also begin to download where before we would get a "Video can't be played because the file is corrupt."

Alternatively for Mac users if they just set media.apple.mp4.enabled to False it also works fine.

Non h.264 mp4 videos will play fine.

Here is a playlist that won't play: http://media.vineyardinstitute.org/other/vi_announcement/firefox-test.html Here is the single video file: http://media.vineyardinstitute.org/other/vi_announcement/05_kingdom_theology.mp4

Is there anything I can change on either the playlist or the video files to get this to work? Why would the h.264 files that worked in Firefox 34 NOT work in 35? I will not be able to re-encode all of the videos, it would take me months. Is this a bug with Firefox?

Also I have tried this in safe mode, tried with every plugin deactivated, I have uninstalled Flash and the videos would not play as well as reinstalling a new version of Flash and a fresh copy of Firefox 35.0

Any help would be much appreciated, we are currently directing all of our users away from Firefox till we get this resolved.

Thanks,

Kyle

How do I fix the H264 support in firefox 43?

Hey,

I noticed that after the Firefox 42 update (or maybe sometime before this) my H264 support was gone. The test site http://www.quirksmode.org/html5/tests/video.html shows only "No video with supported format and MIME type found" message for the H264 movie. The other two work fine. The youtube test site also tells me that H264 is not supported.

I then found that the Windows N version i am using is missing the Media Feature Pack and that firefox requires that for media playback, so I installed it. After restarting the computer firefox crashed when starting it again and again. I had to reset it.

No I am back to square one. Firefox is runnning again but H264 is still not working.

I am thankful for any suggestions.
