Play Any Video on Firefox

Now you do not need any software and plugin for watching videos. All you need to install Firefox on your system. After that you do not need to install any flash plugins too.

This is a 2 step process :
Step 1 = Convert :
Case 1 : Online Videos
If the video is available online (on YouTube or Vimeo) then you can use tinyvid.tv http://tinyvid.tv/convert to convert it to Ogg format and view using Firefox. Firefox .3.5+ has native support to watch/play/stream ogg videos. (native support means you do not need flash plugin).
You can use another utility called "Video DownloadHelper 4.6.2 " ( https://addons.mozilla.org/en-US/firefox/addon/3006 ) addon on Firefox. This is a firefox specific solution. After installing it, you will a download button.
* Click on "Download and Convert"
* click on "Details"
* Select Output format as "Ogg"
* Video codec : libtheora
* Audio codec :verbois
* Extention : ogg
Save it as Ogg profile.

This will download and convert files into ogg (ogv) format and It will be save your system.

Case 2 : Local videos
You can install OggConvert GUI utility ( http://oggconvert.tristanb.net/ ) - It is a GUI based utility which will convert video to ogg format. You can install it using

$ yum install oggconvert

You can convert AVI files to ogg using ffmpeg2theora ( http://v2v.cc/~j/ffmpeg2theora/examples.html )

$ ffmpeg2theora nuxified.avi

Step 2 = View It : for watching ogg , just right click and Open with Firefox. You can also watch on VLC but i prefer Firefox because I feel a better quality with Firefox. Only one thing was missing in Firefox - "Full Screen html5 video playback" So here is the solution - Just install this addon - http://en.design-noir.de/mozilla/fullscreen-video/ Now you can watch full screen video iin Firefox.
