I have a few videos on Ubuntu One cloud web storage and want to play that videos on my blog using html tag without downloading. Because my friend wants to see them withut downloading. When I enter the video URL in Firefox address bar the video stream's and played, but when I use the <video> tag it gives me an error:

contains mime type is not found!

Any body have an idea to play directly Ubuntu One videos in my blog page? thank's

Firefox does not support MP4 for the <video> tag. You will need to convert your video into Ogg or WebM for Firefox to read it. I recommend using WebM as it has the smallest file format.

Install "Ogg Convert":

sudo apt-get install oggconvert  

Make sure you have a local copy of your video.

  1. Open Ogg Convert and select your video file.

enter image description here

2: Make sure "Vido Format" is set to VP8.

3: Click "Advanced" and set "File Format" to WebM

enter image description here

4: Add a name for the file under "File Name" and select a folder to save it too.

5: Click "Convert".

6: Upload the converted file to Ubuntu One.

You're HTML should now look something like this:

<video width="800" height="600" controls>
  <source src="" type="video/mp4">
  <source src="link_To_Webm_File" type="video/webm">

@user127063 Firefox couldn't decode your video. Are you sure you set "Format" to VP8 and "File Format" to WebM? I suggest trying again. – Seth Jan 29 '13 at 18:37
yes! if you not sure, you can download it by this link: the video codec is: VP8 and audio codec is: Vorbis thank you so moch – user127063 Jan 29 '13 at 18:41
