Assembling and Testing a Complex Ogg Theora Video with Command Line Tools and VideoLAN Client (VLC) is a great howto by Terry Hancock at Free Software Magazine:
“Unless you’ve been hiding in a cave for the last few years, you probably know about the free multimedia codecs with the fishy-sounding names from Xiph.org: Ogg Vorbis (for sound) and Ogg Theora (for video). You might be less familiar with other family and friends, including FLAC (lossless audio), Skeleton (metadata stream), and Kate (subtitles). However, together this collection of codecs can be used with the Ogg container format to provide all of the functionality of a DVD video file — multiple soundtracks, full surround sound, high definition, and selectable subtitles. Having created the various streams for a prototype release of “Sintel” in my last few columns, I’m now going to integrate them into a single video file and test it with some players.
Making Movies with Free Software
“This article is part of an on-going series on the challenges I’ve faced in producing two free-licensed movies, Marya Morevna, through the Morevna Project and Lunatics, which we are working on as Anansi Spaceworks.
“In this series of articles, I’ve been assembling a prototype for Lib-Ray — a format I’m inventing in order to have a free, non-DRM way to distribute high definition video. In previous columns, I covered how to create a Theora video stream from PNG images, how to create Ogg FLAC and Vorbis soundtracks, and how to create OggKate subtitle tracks from SRT files. Now, I’m going to put all these together into a single multiplexed stream..”
