Packaging and Video

July 4, 2007

In the last day:

– I tried my hand at packaging something yesterday night and needless to say, my Debian control file was not correct. (Roughly, the control file is the file which shows dependencies, package name, etc. The output of apt-cache search <package>). I’ll give it another shot at some point, but it was a good experiment and taught me a lot about building packages.

– Started the process to upload the Ogg Theora version of the talk John Meinel gave about Bazaar. The real credit goes to one Chicago Ubuntu LoCo member, Aaron Taddei, for filming and encoding the video. I’d like to upload it to Google Video, if anyone has a quick command line way of converting from Ogg to Avi, please let me know. (I’ve never played with video before)


  1. “man ffmpeg” is your friend. Basically something like:

    ffmpeg -i myfile.avi myfile.ogg

    Should do the trick.

    Thanks, Tom

  2. I upload some videos to googlevideo without converting them in avi. ogg is supported natively

  3. Here’s the gstreamer variant for the same task:

    gst-launch-0.10 filesrc location=/tmp/movie.ogg ! oggdemux name=demux ! queue ! theoradec ! ffmpegcolorspace ! ffenc_msmpeg4 ! mux. demux. ! queue ! vorbisdec ! audioconvert ! audioresample ! ffenc_mp2 ! mux. avimux name=mux ! filesink location=/tmp/movie.avi

    While this certainly works, I do not know if it is standard-compliant to stuff “MPEG-1 layer 2”-audio (ffenc_mp2) and “Microsoft MPEG4 Version 3”-video (ffenc_msmpeg4) in an AVI-container.

    In addition to that the above command assumes the OGG-movie to be using theora for video and vorbis for audio, which is still a save bet today. But one could also be using dirac by now, although its implementation “Schroedinger” is still very young and in development.

  4. Hi,

    Blip.tv allow you to upload your ogg video and share them in the same format. then you can use itheora ( http://menguy.aymeric.free.fr/theora/index.php?l=en ) to publish your video on your website using the video witch is on the blip.tv server.

    Good evening.

  5. Thanks for the tips, I was able to do it. You all rock.

  6. thanks for video
