Hello everybody.

Forgive my ignorance about this issue (I searched in the forum with no results) because there are chances that it has already been solved. The point is that I am amazed of istanbul (the screen recorder) and would like to use it to create some videos of me in the computer, however I don't know how to convert its output files (Theora I read) to something more...'commercial' or something most people can see...say mpg.
Is there any application within Fedora that allows me to do such conversion (Theora -> mpg)?

Thanks.
Joe.

use mencoder

mencoder input.ogg -o output.mpeg -ovc lavc -oac mp3lame

Ok, thanks, however when I try to use it I get:


[joe@sempron ~]$ mencoder
mencoder: symbol lookup error: /usr/lib/libavcodec.so.51: undefined symbol: faacDecOpen

Any ideas how can I solve this.
Thanks.

Maybe you have mixed repos, like livna and freshrpms.

Enable just one of them. Then, try to:


yum remove -y faad2 faac

And then, install again:


yum install -y faad2 faac

If it doesn't work, then maybe try to remove mplayer and menconcer and install again (but with one of the repos only, not the two of them enabled).

It worked Duli. I did as you suggested me and now mencoder is operational, however when I removed the first set of packages it removed many other things as well. Anyway it is no longer a problem.
Thanks again.
