on the ffmpeg Vorbis encoder
maikmerten
Archive.org now has all moving images content also available as Ogg Vorbis + Theora. This is great!

This was a massive reencoding effort and the details of what tools were used are available at http://internetarchive.wordpress.com/2008/11/25/fast-and-reliable-way-to-encode-theora-ogg-videos-using-ffmpeg-libtheora-and-liboggz/

A setup to get the job done. However, after having had a closer look I discovered that the Vorbis encodings were done with e.g.

ffmpeg -y -i CapeCodMarsh.avi -vn -acodec vorbis -ac 2 -ab 128k -ar 44100 audio.ogg

Ooops. This means there's massive amount of content, encoded with libavcodec's Vorbis encoder. The only problem: That encoder is rather primitive and produces significantly inferior audio quality compared to libvorbis. And yup, the Archive.org encodings sound rather unpleasant despite not starving on bitrate.

How I wished ffmpeg would loudly complain whenever using unfinished/experimental/not-state-of-the-art encoders.

Re: Vorbis stuff in Moonlight?

Yeah, I feel the same way. I've been doing web development for a while, and having to deal with the proprietary Flash plug-in is a pain. At least with Moonlight I can poke at the code. Patents are too easy to misuse. Tinfoil-hat theories aren't always *entirely* off ;)

If you know anybody who's interested in adding Ogg support to Moonlight, let me (or the moon devs) know, and we'll help them get a dev environment all set up and ready for patching.
