Playing mp4 with videojs in firefox

Question

mp4

The latest version of videojs is extremely easy to integrate. But my brain has already got out of the inability to play mp4 in FF. Directly the video is downloaded without problems. In IE and Chrome it plays without problems. I registered MIME in Apache settings. In htaccess, too , the player does
not play even crack. Writes " no video found in the supported format and MIME type "

People! What to do? I don't want to change the player, I'll have to rewrite the integration.

Answer 1

Who cares, I solved the problem only by installing another player.
Took mediaelementjs.com/ Loved
it! Everything worked out of the box, the same player style on html5 and flash versions

Answer 2

Is changing the video format not an option?

Answer 3

Does not support FF h264, needs to be converted to VP8, that is, to WebM.
