||<>|| = Converting audio and video into open formats = == Converting MP3s to Ogg-Vorbis == Please keep in mind that converting between lossy compression formats, such as MP3 and Ogg-Vorbis, will result in some loss of sound quality. You have a few options for converting MP3s to Ogg-Vorbis format. Two techniques are listed below. * '''Ubuntu's Universe repository includes an easy to use application for mass-converting MP3 music to Ogg Vorbis format.''' * In Ubuntu: * Install the {{{soundconverter}}} package * Open it from the ''Applications->Sound and Video'' menu * Add the files you wish to convert * Tweak the settings for quality, filename, etc. * Start converting! * In Kubuntu: * Follow the above instructions using the {{{soundkonverter}}} package * Open it from "Kmenu -> Multimedia > SoundKonverter" * '''You can easily convert MP3s into Ogg Vorbis format using [[http://audacity.sourceforge.net/|Audacity]]''' * Install the package '''audacity''' * Start Audacity * To import an MP3: File --> Open * Select an MP3 and open it * To export as an Ogg: File --> Export as Ogg Vorbis * Give the file a name, and save == Converting Videos To Ogg Theora == Ubuntu has full support for the Free video format [[http://www.theora.org/|Ogg Theora]] out of the box, and there are a couple of methods for converting videos into this format: * The [[http://www.videolan.org|VideoLAN]] project has given the '''VLC''' media player (available in Ubuntu's Universe repository) streaming capabilities, including the ability to stream into a file. To encode an Ogg Theora video of a file VLC is capable of playing * Install the {{{vlc}}} package and run it (if working from command line these instructions are for the {{{vlc}}} or {{{wxvlc}}} commands, not the {{{svlc}}} command) * Choose ''File->Open File'' (NOT ''Quick Open File'') * In the ''File'' tab select the ''Browse'' button and choose the video you wish to convert * Tick the box next to ''Stream output'' then click the ''Settings'' button which becomes accessible * Under ''Output Methods'' tick ''File'' then click the ''Browse'' button and choose what you want to save your output file as (possibly ending the filename with ".ogg", although that is not strictly needed) * Change ''Encapsulation Method'' to ''Ogg'' and tick ''Video codec'' and ''Audio codec'', changing them to ''theo'' and ''vorb'' respectively * Choose your desired bit rates for audio and video (you will need to do some experimentation with these to produce small files of high quality) * Press ''OK'' in the settings window, then again in the open file window. The file will now stream to an Ogg Theora video instead of being played normally. * The program ffmpeg2theora is slightly more reliable than VLC, but it is based on the command line: * Install {{{ffmpeg2theora}}} from Universe * Open a terminal in the same folder as the video you wish to convert * Run the command {{{ffmpeg2theora -v N video_file}}} where N is the output quality and video_file is the filename of the video. This will produce a file called "video_file.ogg" * For more options see the ffmpeg2theora manual with the command {{{man ffmpeg2theroa}}} * There is a rudimentary GUI available for ffmpeg2theora which allows configuration of most ffmpeg2theora options and provides a useful progress bar. It uses the QT4 toolkit, so you may need to install some extra packages to compile or use it. A pre-compiled binary can be found [[http://p80.free.fr/katiuska-0.1-bin.tar.bz2|here]] and the corresponding source can be found [[http://p80.free.fr/katiuska-0.1.tar.bz2|here]]. * The program '''Transmageddon''' is a very simple gui for converting videos to Ogg Theora and other formats. It can be installed by typing '''sudo apt install transmageddon''' into the terminal. The settings are very limited because it targets people with low computer skills, however the default settings provide very reliable encodings that produce the best quality/file size possible. The only drawback is that it doesn't offer batch encoding, you're limited to one file at a time. Just open the program, choose the media file you want, and hit transcode, it will convert directly into the .ogg/theora/vorbis format, at best quality without further adjustments.
