Links

• The dbnvp directory (to get the sources of all php files in this directory, download all_php_files.zip.php and save it without the .php extension, and then open it or unzip it as a zip file).
• A post in Jim Colliander's blog.
• The project birthplace (and further links) at 2009-06/one/Streaming_Video.pdf.
• Mozilla on video: https://developer.mozilla.org/En/HTML/Element/Video and https://developer.mozilla.org/en/Using_audio_and_video_in_Firefox.
• Flumotion and Cortado: http://www.flumotion.net/ and http://svn.wikimedia.org/viewvc/mediawiki/trunk/cortado/.
• Converting videos to theora: http://v2v.cc/~j/ffmpeg2theora/.
• Icecast: http://www.icecast.org/.
• VLC: http://www.videolan.org/
• "HTML5 Video" in the Theora Coockbook: http://en.flossmanuals.net/TheoraCookbook/HTML5.

To Do

• Save current time and other state parameters with cookies.
• "Previous/next" links.
• "These notes are (mostly) by the students and for the students...".
• Allow linking into a specific video time.
• Single frame extraction: ffmpeg -i ogg/wClips-120222_720.ogg -f image2 -ss 00:03:31 -vframes 1 -r 1 frames/wClips-120222-000351.jpg.

Done

• Allow an independent refresh of the "comments" panel.
• Allow linking of blackboard shots. Each Talk.php may set parameters to manage blackboard shots:
  • "bbsfolder" - a directory for the bbs.
  • "bbstime" - a function to compute the absolute time of a shot from its filename. In case of an invalid file, should return 0.
  • In addition, Talk.php should contain a "startingtime" and an "endingtime" parameters.
