Do you have the "OpenH264 Video Codec provided by Cisco Systems" firefox add-on |
43 |
installed (I think it comes with firefox). I have it but I still don't have |
44 |
H.264 checked on that page and I can't play some H.264 videos like this one |
45 |
https://www.microsoft.com/microsoft-hololens/en-us. If you have it, do you |
46 |
mind disabling it to check if that's where you're getting H.264 support from? |

I have no problems playing youtube videos without it (both HTML5 and Flash) |
49 |
and I don't have gstreamer enabled on firefox. |
