Hi all,
Here's some Inkboard demo materials:
http://www.rose-hulman.edu/~yipdw/inkboard/inkboard-screenshot-1.png (1280x1024, 187 kB)
http://www.rose-hulman.edu/~yipdw/inkboard/inkboard-demo-2.mp4 (H.264 (using x264), 1136x864, ~187sec, 2.1 MB)
http://www.rose-hulman.edu/~yipdw/inkboard/inkboard-demo-2.avi (H.263 (using XviD), 1136x864, ~187sec, 11 MB)
The videos have the same content; however, the video in the MP4 container is substantially smaller (and looks better, IMHO). I'd like to hear if it's playable by other people. (I know a Media Player Classic/recent version of ffdshow setup can handle it, but I'd like to hear reports from users of more "standard" players, i.e. QuickTime Player.)

David, the .avi demo played from both Konqueror and Firefox in my Debian unstable setup - the mp4 wouldn't play at all in my setup, including xmms. Nice demo.

Hi John,
Thanks for the report.
I should have said that I encoded both the mp4 and avi using mencoder (dev-CVS-050924-17:15-3.4.4), x264 r300, and XviD 1.0.2. I tested playback using an mplayer compile from the same CVS checkout on Gentoo amd64.
The x264 encode used 3 bframes, 5 reference frames, and B-frame pyramid (that's all I can really think of that'd cause issues...) The XviD encode didn't use anything really special -- trellis quantization is all that comes to mind.

Hi David,
Could not get the mp4 to work. Not surprising since its the first time I've ever tried an mp4.
However, also could not get the avi to work. This was a surprise as I use avi's regularly for tutorials. Neither Camtasia or Windows Media Player 9 would touch it.
I am using win2000. Erik

The mp4 works fine with VLC on OS X (very cool, btw), but it was just white in Quicktime. The avi works in both VLC and Quicktime.

Looks amazing. But I was wondering what happens when two people make conflicting changes.

ermm.. WOW. very cool!

This is an aspect of Inkboard that will be much improved upon in subsequent releases.
The current release does some checks and munges to manage conflicting changes, but it's hardly perfect, and definitely does allow documents to diverge.
The two next major steps for Inkboard, I think, are Win32/Mac OS X support and implementation of the Palimpsest data model (see http://cs-people.bu.edu/dgd/thesis/original_paper.html), which should give us a much cleaner, more flexible conflict management system.

Hi,
the mp4 works with vlc (0.8.2) but not with xine (0.99.3), MPlayer (1.0pre6-3.3.5) or totem (1.2.0 gstreamer)

Hmmm, the mp4 did not work with my vlc (0.8.2) on Debian unstable. Maybe vlc needs some library or setting?
David, for now, seems like .avi is the more universal approach on linux.

I think we must not assume playability of mp4 everywhere.

Can this one be scaled down in resolution? It's way too large IMHO.

Yeah, I'm getting that same impression. Someday, though... :)

Sure -- here's a 848x644 XviD encode, 6.2 MB. I've not used anything that DivX 5.0 cannot handle (I don't think), so I've changed the codec identifier to that of DivX 5.x's, which should give us a bigger audience. (I hope.)
It's a bit blurred due to the scaling, but still readable IMHO.

Hi, After several abortive attempts with media players I finally got the avi to work with Hyplay. Erik, using Win2k
