Q:

What version of theora is ffmpeg using

I have compiled the recent version of ffmpeg with the support for theora encoding with libtheoa. Does anyone knows what version of theora is ffmpeg going to be using?
Is it 1.1.1 or 1.2.0 Alpha?
I have compiled ffmpeg and sadly I could not find the version that ffmpeg is using and I doubt that it is using the 1.2 version however I found a ffmpeg binary file that is using theora 1.2 alpha version ffmpeg2theora 0.29

A:

If you have compiled it yourself (as you've said in the comment) using --enable-libtheora during the configuration, then it will be the same thing as what is currently installed on your computer. You can check that by running
sudo apt-cache showpkg libtheora-dev
