ogg theora videos to avi

Filed under
Howtos

I've been writing a Ruby computer programming textbook (the going is slow). Along with the book will be a series of instructional videos on CD showing video computer screen clips with audio narration.

I've been using gtk-recordmydesktop to record my computer screen and narration. This is working fairly well, both in terms of video and audio quality.

However, since gtk-recordmydesktop records in ogg theora form, I need to convert these videos into something that most MS-Windows users can play (without downloading and installing vlc media player). Also, I can't use Linux video editing software on ogg theora videos--they won't work with this format (I've tried cinelerra, lives, and others).

I've done very little with video on computers, and I find the number of codecs/compression formats/container formats bewildering.

But I have done some research on how to do the ogg theora to avi conversion. I finally found a solution that seems to work, using mencoder.

Assuming the input file is out.ogg, and the desired output file is out.avi, the syntax looks like this:
mencoder out.ogg -o out.avi -oac mp3lame -ovc lavc

I need to do more testing, but, so far, this seems to work ok.

And, before somebody flames me, I do realize that we should encourage the use of open formats like ogg theora.

  • Minwaita: A Compact Version of Theme Adwaita for Gnome Desktop
    As you may already know that Ubuntu is switching back to Gnome, this is the transition time for Ubuntu to switch back. Some creators are motivated and creating themes for Gnome desktop, which is a good thing and hopefully we shall see plenty of Gnome themes and icons around soon. As its name shows "Minwaita" it is minimal/compact version of Adwaita theme, the theme is available after some enhancements to make Gnome more sleek and more vanilla Gnome experience without moving to away from Adwaita's design. This theme is compatible with Gnome 3.20 and up versions. This theme was released back in November, 2016 and still in continuous development that means if you find any problem or bug in the theme then report it to get it fixed in the next update. Obsidian-1 icons used in the following screenshots.

  • Widget hierarchies in GTK+ 4.0
    In GTK+3, only GtkContainer subclasses can have child widgets. This makes a lot of sense for “public” container children like we know them, e.g. GtkBox — i.e. the developer can add, remove and reorder child widgets arbitrarily and the container just does layout.
