Sometime ago I checked out recordmydesktop (<a href="http://recordmydesktop.iovar.org/about.php" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://recordmydesktop.iovar.org/about.php</a>) to see how feasible it would be for XO owners to record screencasts. It is a command-line program, with separate gtk and qt frontends.
<br><br>I installed it into my B4 using <br>yum install recordmydesktop<br>I did some testing of the options the program has, and tried to tune them to get a balance between the speed of the system while recording, the size of the final video (
5.6 MB for 6 minutes in my test) and speed when playing the video on a XO (also good with my test). <br>The command I used was:<br>recordmydesktop --no-sound -v quality 10 -delay 10 -fps 10 <br>and the output:<br><a href="http://ia341239.us.archive.org/2/items/ScreencastOfBetaVersionOfSugarDesktopOnAXoLaptop/tmpNfhxcl.ogg" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://ia341239.us.archive.org/2/items/ScreencastOfBetaVersionOfSugarDesktopOnAXoLaptop/tmpNfhxcl.ogg</a><br><br>It has the ability to record sound as well (which I disabled), so if in your activity you enabled the microphone while recording, it would be possible to do what you wanted, the kid/narrate things.

I'd like some feedback on an idea for a tutorial recording activity.<br><br>The idea is to allow the kids and teachers to use the laptop to create<br>their own tutorials on how to use the laptop, or how do do some neat
<br>trick with it, program it, use an activity etc. The recording can be<br>in their own language, with explanations at their own level.<br><br>The idea came from a recent experience where I created some flash<br>movies showing how clustered Samba works, and the great positive
<br>feedback I got from that (see<br><a href="http://samba.org/%7Etridge/ctdb_movies/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://samba.org/~tridge/ctdb_movies/</a>). We already had detailed
<br>documents on how to setup clustered Samba and what it could do, but
<br>the movies made a big difference anyway. People respond to<br>demonstrations more than documents.<br><br>The basic tool I'm thinking of using is pyvnc2swf:<br><br> <a href="http://www.unixuser.org/%7Eeuske/vnc2swf/pyvnc2swf.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://www.unixuser.org/~euske/vnc2swf/pyvnc2swf.html</a><br><br>combined with x11vnc.<br><br>The activity would start with a dialog box like this:<br><br> ===============================================<br> To start recording your tutorial, click RECORD
<br> To end recording press Alt-7<br><br> <RECORD> <CANCEL><br> ===============================================<br><br>When RECORD is clicked the dialog would go away, and the laptop would
<br>be fully usable as normal. All activity will be recorded, including<br>voice.<br><br>At the end of the recording the user clicks Alt-7, and a dialog<br>appears where they get to name their recording. Then there needs to be
<br>a way to view recordings they have made, and share them with others,<br>probably via posting to a web site.<br><br>It might also be nice to allow the user to enable/disable the camera<br>during the recordings with a hot-key. This would display the camera
<br>view as a smallish box on the right hand side, which would then become<br>part of the recording.<br><br>I don't know how much of this idea will be possible, as perhaps the<br>cpu and/or storage constraints will make it impractical. I also don't
<br>know whether I'm capable of doing any of this as my python skills are<br>non-existant and I don't have much spare time, but if anyone would<br>like to jump in and help then I think it would be worth trying.<br>
<br>I think this activity would be particularly useful for teacher to<br>teacher communication. Some teachers will have great ideas on how to<br>get the most out of these laptops, and we need a way to get those<br>ideas communicated as widely as possible. This might provide a
<br>reasonable way to do that.<br><br>I've put a trivial example of an OLPC 'calculator' tutorial that I<br>have created using x11vnc on my B2 at:<br><br> <a href="http://samba.org/%7Etridge/OLPC/calculator.html" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
http://samba.org/~tridge/OLPC/calculator.html</a><br><br>Some problems with it:<br><br> - I should have scaled it better so it fits better when viewed on a OLPC<br> - sound doesn't play back when I view this on my B2. I don't know why
<br> yet.<br> - the movie is too large, mostly because the sound is too high<br> quality I think.<br> - the Web activity consumes huge gobs of memory when playing back<br> this tiny movie. It brings my 128M laptop to a crawl.
<br> - gnash consumes too much cpu and memory, at least for a B2<br> - the JS framing in the movie and the pause control is not very good<br><br>The above example was creating running x11vnc on the B2 and running<br>pyvnc2swf on my Debian laptop pointed at the B2 over a wireless
<br>link. I haven't got the pyvnv2swf python code running on the B2 yet<br>(did I mention that my python skills are non-existant?)<br><br>Cheers, Tridge<br>_______________________________________________<br>Sugar mailing list
