| + | =='''Known issues:'''== |
| + | (Listed in order of severity.) |
| | | |
- | ==Recording devices== | + | *Find a way to add <tt>style="width:352px;"</tt> to embed code in 352×240 streams. |
- | ===Known issues===
| + | |
- | *Fixup non-compliment DV hardware + firewire-core [https://bugzilla.redhat.com/show_bug.cgi?id=449252 Example ticket]
| + | |
| | | |
- | ===Possibly fixable===
| + | *[[OMwiki:Speakers|Speaker labels]] work for annotations but not transcripts. Also need to figure out AJAX auto-complete magic. |
- | *Rework [http://modcopy.sourceforge.net/ modcopy] to avoid mmap calls on JFFS2 filesystems (''e.g.'', the OLPC-XO). [http://sourceforge.net/apps/trac/modcopy/ticket/9 Ticket] | + | |
- | *Investigate audio ground loops and prevention techniques
| + | |
| | | |
- | ===Dreamlist===
| + | *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) |
- | *Find a portable camera or device that records footage from ''two'' audio sources (''e.g.'', XRL mic + ambient mic) time-synchronized to a video track. | + | |
- | *Migrate to open-firmware cameras that record directly to Ogg; also include simplified on-camera editing. Elphel has completely-open [http://www3.elphel.com/353_turnkey network cameras] supported by the [http://cinema.elphel.com/ Apertus] community.
| + | |
- | *Auto-balancing, wireless, golfball-sized mics that are mutable by the camera. Best for when push-to-talk mics are not available.
| + | |
- | *Have cameras set to blur-out individuals broadcasting a 'do not record my voice, person, or both' flag ''via'' iPhones, RFID, or colored stickers as mentioned in Yochai Benkler's keynote at OVC 2009.
| + | |
| | | |
- | <br>
| + | *Edit [[MediaWiki:Common.js]] to download animated gifs only [[OMwiki:Finding_aid|when 'show' is clicked]] to avoid long page loads. |
| | | |
- | ==Editing==
| + | *Video playback might take ~6 seconds to start for timecodes towards the end of the meeting (pending seeking support in [http://www.xiph.org/oggz/ oggz-chop]). Also, Google Chrome won't start playback if oggz-chop is used. |
- | ===Known issues===
| + | |
- | *[http://cinelerra.org/ Cinelerra-CV] is buggy and somewhat dated. Wait for Lumiera to mature. | + | |
- | ===Possibly fixable===
| + | |
- | *Add YUV4MPEG support in [http://www.blender.org/ Blender] to enable direct output to [http://v2v.cc/~j/ffmpeg2theora/ ffmpeg2theora] ([http://lists.mplayerhq.hu/pipermail/libav-user/2009-March/002639.html email thread]), building upon [[File:Henningsen_7oct2009_blender-svn.tar.bz2|Stephan Henningsen's lead.]] Also build-in yuv4ogg suFigure out a pport as per [http://web.mit.edu/xiphmont/Public/theora/demo8.html xiphmont's lead.]
| + | |
- | *Find a plugin/filter that synchronizes audio captured from a secondary source; slight a/v sync drifts accumulate over time, making 2nd-track audio recombination difficult.
| + | |
- | *Document export options to accommodate a wider range of video editors; [http://php.scripts.psu.edu/gsc127/blogs/2009/05/firefox-ogg-firefogg-demo.php firefogg] is an option.
| + | |
| | | |
- | ===Dreamlist===
| + | *[http://cinelerra.org/ Cinelerra-CV] is buggy (compilation from source helps). Document rendering options on other video editors (e.g., [http://www.xiph.org/quicktime/ XiphQT]) |
- | *Theora encoding ''via'' hardware acceleration (TI C64x+ DSP or an Elphel card?) | + | |
- | *Find a sensible audio compressor to avoid the time-intensive task of adjusting audio to comfortable listening levels.
| + | |
| | | |

- | ==Archiving==
| |
- | ===Known issues===
| |
- | *FTP on the Internet Archive is only available for item download and initial upload; item editing is browser-based.
| |
- | *Video playback on Internet Archive description pages (inc. <video> fallback) requires the presence of a Flash-based derived file. These derived files are manually deleted post-upload.
| |
- | *OpenMeetings.org is not crawled by the Wayback Machine.
| |
| | | |
- | ===To-do=== | + | =='''Scripts needed:'''== |
| *Retool [http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/MetavidWiki/maintenance/download_from_archive_org.php?view=markup download_from_archive_org.php] to work with different source videos and meta tags from the [http://archive.org Internet Archive], using [[OMwiki:Tech/OMwiki-import.php|this wikipage]] as a working draft. | | *Retool [http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/MetavidWiki/maintenance/download_from_archive_org.php?view=markup download_from_archive_org.php] to work with different source videos and meta tags from the [http://archive.org Internet Archive], using [[OMwiki:Tech/OMwiki-import.php|this wikipage]] as a working draft. |
| + | *Draft a script to import MetaVidWiki clips from apps that can produce [[wikipedia:SubRip|.srt]] or [[wikipedia:Continuous_Media_Markup_Language|.cmml]] captions (''e.g.,'' [http://gnome-subtitles.sourceforge.net/ Gnome Subtitles]) |
| | | |
- | ===Dreamlist===
| |
- | *Implement template support on the [http://archive.org Internet Archive] description pages.
| |
- | *Secure logins + strong item deletion-prevention.

- | ==OMwiki issues==
| |
- | ===Known issues===
| |
- | *Find a way to add <code>style="width:352px;"</code> to embed code in 352×240 streams and fix aspect ratio for 352×240 thumbnails when in category view.
| |
- | *Google Chrome has buggy Theora support.
| |
- | *Edit [[MediaWiki:Common.js]] to download animated gifs only [[OMwiki:Finding_aid|when 'show' is clicked]] to avoid long page loads.
| |
- | *[[OMwiki:Speakers|Speaker labels]] work for annotations but not transcripts.
| |
- |
| |
- | *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)
| |
- | *White-on-black site design works well for focusing attention on video streams (right?), but fares poorly for text-heavy pages. Implement an automatic "turn down the lights" feature when video is in a 'play' state.
| |
- |
| |
- | ===To-do===
| |
| *Add a Vorbis-only option on video streams for low-bandwidth connections. | | *Add a Vorbis-only option on video streams for low-bandwidth connections. |
- | *Turn on [http://www.mediawiki.org/wiki/Extension:OpenID OpenID logins.] Need to figure out how to link non-PEAR libraries to non-recompilable PHP or upgrade web hosting.
| |
- | *Figure out AJAX auto-complete magic.
| |
- | *Fix Google search listing.
| |
- | *Start up project blogging, @openmeetings.org email addresses, and listing of similar projects.
| |
| | | |
- | ===Dreamlist===
| + | *Replace animated GIFs with low-FPS, clickable, enlargeable Theora. Alternatively, use [http://pad.ma/ Pad.ma]-style mouse-overs (see [https://wiki.pad.ma/browser/padma.dev/padma/static/javascript/info.js?rev=padma.dev%2C354&order=size&desc=1 <nowiki>$(imagePoster).load(function() {...})</nowiki>]). |
- | *[http://lists.wikimedia.org/pipermail/metavid-l/2009-August/000055.html Ideas on MetaVid-l] (''e.g.'', [http://identi.ca Identi.ca] integration)
| + | |
- | *Replace animated GIFs with low-FPS, enlargeable, jump-to-timecode Theora. Alternatively, use [http://pad.ma/ Pad.ma]-style mouse-overs (see [https://wiki.pad.ma/browser/padma.dev/padma/static/javascript/info.js?rev=padma.dev%2C354&order=size&desc=1 <nowiki>$(imagePoster).load(function() {...})</nowiki>]). The thumbnails should cycle through the meeting in large time chunks when non-mouseover'd, and then display clickable frames according the how far the mouse is from the left edge when mouseover'd. Include ability to pause all animations and step-through lock-step upon mouse clicks. | + | |
| | | |
| + | *Add YUV4MPEG support in [http://www.blender.org/ Blender] to enable direct output to [http://v2v.cc/~j/ffmpeg2theora/ ffmpeg2theora] ([http://lists.mplayerhq.hu/pipermail/libav-user/2009-March/002639.html email thread]) |
| | | |
- | <br>
| + | *Squash bugs (esp., video non-playback) in mwEmbed's [http://svn.wikimedia.org/viewvc/mediawiki/trunk/phase3/js2/mwEmbed/libSequencer/ libSequencer]. |
- | ==Video post-processing==
| + | |
- | ===Known issues===
| + | |
- | *No video post-processing is implemented. | + | |
- | ===To-do===
| + | |
- | *Figure out best options to breakdown tons of video.
| + | |
- | *Fixup and advertise availability of [[OMwiki:Nodes|echo.openmeetings.org]] for compute tasks.
| + | |
- | *Machine synchronization of known-good transcripts to video (i.e., match individual words to the exact timecode spoken).
| + | |
| | | |
- | ===Dreamlist===
| + | *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 ([http://cmusphinx.sourceforge.net/ CMU Sphinx?]). Hopefully add speaker identification based on the vocal profile, and maybe even facial recognition. |

Hopefully add speaker identification based on the vocal profile, and maybe even facial recognition and emotional categorization (''e.g.'', laughter). | + | |
- | *Have individuals appear as virtual avatars in-video (''i.e.'', Second Life or Avatar-esque), according to user preference.
| + | |
| | | |
| + | *Figure out a content delivery network. |
| | | |

| | | |
- | ==External apps/reuse==
| + | <br/> |
- | ===Known issues===
| + | |
- | *Wait for mwEmbed's [http://svn.wikimedia.org/viewvc/mediawiki/trunk/phase3/js2/mwEmbed/libSequencer/ libSequencer] to mature; squash bugs.
| + | |
- | ===To-do===
| + | |
- | *ffmpeg/mplayer seems to handle duplicate Theora frames poorly, breaking A/V sync and thus limiting video reuse. Submit bug report.
| + | |
- | *Draft a script to import MetaVidWiki clips from apps that can produce [[wikipedia:SubRip|.srt]] or [[wikipedia:Continuous_Media_Markup_Language|.cmml]] captions (''e.g.,'' [http://gnome-subtitles.sourceforge.net/ Gnome Subtitles])
| + | |
- | *Figure out a easy way to integrate playback with blog platforms, including various commenting systems (''i.e.'', plugins). [http://www.personal.psu.edu/gsc127/blogs/2009/06/enabling-video-content-on-your.html Known hacks]
