Presentation that Tracey Jaquith of archive.org gave at the (1st) Stanford Open Source Labs (un)Conference

It was a 45 minute talk that focused on
Ogg Theora video, Firefox 3.1, Archive.org & Wikimedia support.

Internet Archive has been working with Wikimedia and Metavid, as well as other opensource organizations to further open software, open content, and open culture.

Theora is a promising video codec that will ship inside Firefox 3.1 that will allow people to simply embed a video with a new [video] HTML tag, similar to the familiar [img] HTML tag.

You can also see it online here.

Slide 3: Ogg Theora video Thought to be most free, unencumbered video codec Libraries/tools available from: •xiph.org (libtheora) •annodex.net/software/liboggz/ •ffmpeg •flowplayer
Slide 4: archive.org mission to allow free uploading, storage, and serving for all •1 million books •400K audio progams and concerts •100 billion web pages The Internet Archive, a 501(c)(3) non-profit, is building a digital library of Internet sites and other cultural artifacts in digital form. Like a paper library, we provide free access to researchers, historians, scholars, and the general public.
Slide 5: archive.org will rederive movies We have news: •Democracy Now! •US congress (w/ metavid) games, speed runs cartoons/animations feature films and more!
Slide 6: night of the living dead
Slide 7: how we make ogv fast/reliably High Level: •use ffmpeg to turn any video to \"rawvideo\" •pipe its output to *another* ffmpeg to turn the video to \"yuv4mpegpipe\" •pipe its output to the libtheora tool •for videos with audio, ffmpeg create a vorbis audio .ogg file. •add tasty metadata (with liboggz utils). •combine the video and audio ogg files to an .ogv output! tikirobot.net/wp/author/tracey-pooh (or just google \"ogv tracey\" 8-)
Slide 8: [code] (set to input) ffmpeg -an -deinterlace -s 400x300 -r 20.00 -i CapeCodMarsh.avi -vcodec rawvideo -pix_fmt yuv420p -f rawvideo - | ffmpeg -an -f rawvideo -s 400x300 -r 20.00 -i - -f yuv4mpegpipe - | libtheora-1.0/lt-encoder_example --video-rate-target 512k - -o tmp.ogv; pipes = nice on 2+ cores ffmpeg -i CapeCodMarsh.avi -vn -acodec vorbis -ac 2 -ab 128k -ar 44100 audio.ogg; oggz-comment audio.ogg -o audio2.ogg TITLE=\"Cape Cod Marsh\" ARTIST=\"Tracey Jaquith\" LICENSE=\"http://creativecommons.org/licenses/publicdomain/\" DATE=\"2004\" ORGANIZATION=\"Dumb Bunny Productions\" LOCATION=http://www.archive.org/details/CapeCodMarsh; oggzmerge tmp.ogv audio2.ogg -o CapeCodMarsh.ogv;
Slide 9: archive.org is ... adding metadata to .ogv (and h.264 .mp4) jumping into streams -- oggzchop (and mod_h264_streaming with lighttpd) timecodes, standards for accessing: •annodex.net/TR/draft-pfeiffer-temporal-fragments-03.html •archive.org/download/to-SF/toSF_512kb.mp4?t=74.5 serving search results in JSON, CSV, XML serving item metadata in JSON
Slide 10: h.264 mp4 creation ffmpeg -i CapeCodMarsh.avi -b 512k -s 320x240 -vcodec h264 -r 20.00 -bf 0 -level 13 -qmax 35 -maxrate 768k -title \"Cape Cod Marsh - http://www.archive.org/details/CapeCodMarsh\" -year \"2004\" -comment \"license:http://creativecommons.org/licenses/publicdomain/\" -author \"Tracey Jaquith\" -pass 1 -an cape.mp4; [same args above...] -pass 2 -acodec aac -ab 64k -ac 2 cape.mp4; mp4creator -optimize cape.mp4 pluses: minuses: •plays on iphone •longer to make •plays in flash plugin •possible licensing / IP •works with lighttpd issues mod_h264_streaming
Slide 11: metavid / wiki metavid has a *great* web player that: will natively play .ogv if codec will use flowplayer if flash/h.264 can play MPEG will use chopping/seeking for snippets can jump from clip format A to clip format B is now being incorporated into wikimedia
Slide 12: goals make CC licensed (and otherwise) videos available enable online transclusion and editing/mashups with wikimedia and metavid rederive nearly 200,000 movies!
