Known issues:

(Listed in order of severity.)

  • Find a way to add style="width:352px;" to embed code in 352×240 streams.
  • Speaker labels work for annotations but not transcripts. Also need to figure out AJAX auto-complete magic.
  • Search works but has a few issues (punctuation stripped, 'play inline' plays audio although video is paused, search-by-date not yet enabled for all videos)
  • Video playback might take ~6 seconds to start for timecodes towards the end of the meeting (pending seeking support in oggz-chop). Also, Google Chrome won't start playback if oggz-chop is used.
  • Cinelerra-CV is buggy (compilation from source helps). Document rendering options on other video editors (e.g., XiphQT)



Scripts needed:



New Features

  • Add a Vorbis-only option on video streams for low-bandwidth connections.
  • Squash bugs (esp., video non-playback) in mwEmbed's libSequencer.
  • Identify a way to output time ranges generated from multi-speaker audio files, with each time range corresponding to the duration of how long a person spoke for (CMU Sphinx?). Hopefully add speaker identification based on the vocal profile, and maybe even facial recognition.
  • Figure out a content delivery network.
