Revision as of 02:06, 8 October 2009
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)
- Edit MediaWiki:Common.js to download animated gifs only when 'show' is clicked to avoid long page loads.
- 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:
- Retool download_from_archive_org.php to work with different source videos and meta tags from the Internet Archive, using this wikipage as a working draft.
- Draft a script to import MetaVidWiki clips from apps that can produce .srt or .cmml captions (e.g., Gnome Subtitles)
New Features
- Add a Vorbis-only option on video streams for low-bandwidth connections.
- Replace animated GIFs with low-FPS, clickable, enlargeable Theora. Alternatively, use Pad.ma-style mouse-overs (see $(imagePoster).load(function() {...})).
- Add YUV4MPEG support in Blender to enable direct output to ffmpeg2theora (email thread)
- 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.
