Known issues:

• 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)

• The two stream sizes (352×240 and 424×240) are hard-coded per-stream as there is not a simple way to lookup file_desc_msg from the mv_stream_files table. This is an ugly hack.

Also, add style="width:352px;" to embed code in 352×240 streams.

• Video playback might take ~6 seconds to start (pending seeking support in oggz-chop)

• An occasional ~30-second JavaScript-related delay, unknown cause, when using native playback on 64bit Minefield and possibly other browsers. No bandwidth transfer, no CPU usage, the page just waits then eventually loads.

• Cinelerra-CV is buggy (compilation from source helps)
• YUV4MPEG support in Blender, to send to ffmpeg2theora (email thread)

Scripts needed:

• Retool download_from_archive_org.php to work with different source videos and meta tags from the Internet Archive. Simultaneously generate Media RSS <items> from the same information, and insert date_start_time into mv_streams.
• Script to import MetaVidWiki clips from apps that can produce .srt or .cmml captions (e.g., Gnome Subtitles)
• Find a command-line script that produces .torrents that include multiple HTTP seeds, no tracker, a comment, and "just works" with Mainline.

Development:

• Email thread on MetaVid-l
• Automated speaker recognition by frame tagging, corroborated by voice profiles

Communicate:

• Join and post to MetaVid-l
• Join #metavid and #mediawiki
