vlc, from rpmfusion. But are you sure you need to convert it? vlc will also play Matroska videos. If it's a matter of a codec, you should be able to find one, almost automatically.
Before trying to convert this video, find an app that supports the Matroska video format for whatever it is you want to do with it, whether it's playing or burning.

and this app makes it HTML5 compatible? H264/AAc videso are played by any decive these days and a de-facto standard

avidemux seems to be a great app. I've used it only in Gentoo, however it is also available for fedora at rpmfusion site.

Is there a "MP2-4" video format. :)

No, but you have MP2 and MP3 sound-only files and MP4 videos. MP4 seems to be the download-of-choice from youtube.com, for example.

- MPEG-1(2) Audio Layer II aka "MP2" - MPEG-1(2) Audio Layer III aka "MP3" - MPEG-4 Part 3 aka "MPEG-4 Audio" - MPEG-4 Part 14 aka "MP4" is a multimedia container for certain types of video, audio and subtitle tracks, same as MKV(матрёшка) itself.

Youtube and anything which provides videos for web is using H.264/MPEG-4 Part 10 / AVC, to be specific H264 BASELINE PROFILE and nothing else in context of "MP4" because THIS is the spec which is supported by Smartphones, Tablets, mobile browsers up to Firefox on Android in recent releases and most hardware-devices including hardware acceleration

Anyhow, OP's question remains unclear.

Wow, I see why you want it in a script. I confess to being lazy and just setting the output filename to {something}.webm and getting a pretty portable file. I adjust frame size and video bitrate as needed, generally defaults work.
I use "-target ntsc-dvd" a lot to get a file which will go on a DVD should I need it.

portable?
* Apple does not support it * Microsoft does not support it * many mobile devices does not support it * most hardware-devices does not support it
don't get me wrong, i owuld love to have VP8 in the position H264 is, but since it's part of my daily job to write software which supports most to all clients with videos that's not how the world works for at least some years from now

Hum, tried this with an old cell phone which didn't have the latest and greatest updates, the big long script works with old phones, and the ffmpeg idea of "webm" doesn't. On the other hand, the mp4 was more than double the size, so there are tradeoffs. I suspect the OP wants portability above all.
I use "-target ntsc-dvd" a lot to get a file which will go on a DVD should I need it.

I was typing a reply to my post commenting on the same issue, Ed's script is quite useful, but but I did resize the the frames down to something suitable for mobile, my original was TV capture at 1920x1080, mp4 was about 21MB/min, vs. 1500k/min at 720x480.
Even on a tablet that looks acceptable for many things, and until I trade my tf300 for a tf700 and get new glasses, it will do.
