webmhd and webmsd don't play on Firefox. Where is the vp8 converstion in MIro?

I have converted an mp4 video using Miro, into webmhd and webmsd.

None of them play in Firefox!!!

Note that I have not even uploaded it to the server where the website is.

I am just clicking on the file in my computer and it does not play.

The only way to play the video in Firefox is to go to and use their online tool to convert it to webm vp8.

How can I use Miro to convert the mp4 to webm vp8?

Well, usually there is some software and website specially designed for this purpose.

This is the site I always use to download mp3 or mp4 from YouTube!! It can be used in most video or audio sites.


Have you solved it ?

I have the same issue, and looking for a resolution. What is weird is that my webmHD videos will not play from the very beginning in firefox, but if I seek perhaps 15 seconds into a video (is different from video to video, but always the same for a specific video), then the video can be started. The same videos work in Chrome.

It seems it's just another format, and FireFox needs "webm" not "webmhd" or "webmsd", it's interesting that support didn't answer this ticket so long.
