Re: WebM format for Record

Re: [Sugar-devel] acti-plications: write once, run anywhere?
Am I correct that sugar and gnome can co-exist in two different ways right now? 1. On a dual boot machine, probably an xo, where activities are installed into /home/user/Activities/ where useris probably *always *olpc 2. Sugar as an application in gnome (within a Xephyr window) where activities can be installed a few places, including /home/user/Activities/ Next question.. am I correct that the *preferred *way for users to install activities and applications is: A. Sugar activities are installed via .xo bundles. B. Gnome activities are installed via .rpm files. Now, how should activity developers (who are not writing system libraries like xulrunner or squeak) put their content so that their activity/application can be viewed from both sugar and gnome? I am asking so children can avoid having redundant copies of files on every machine running both gnome and sugar. This is a real problem for content rich activities with lots of media assets. By default, an rpm file will install into /usr/lib/python/. This is obviously not where sugar looks for its activities. If we could get an 'educational content' rpm to install its contents anywhere... where should we put its assets so that they are automatically where they should be for sugar too?

Re: [Sugar-devel] acti-plications: write once, run anywhere?
Let's assume delivery of the activity-application is via a usb stick. Let's also assume the video game has 200mb of assets. The goal is to make it as easy as possible to install the activity-application once, from either side, and to put the assets in one place. For sugar, this would be a ~200mb xo bundle on the usb stick. For gnome, this might be a ~200mb rpm on the usb stick. Do all activity and application developers have write access to any part of the system where they can add the libraries that they need to the system from either gnome or sugar side and then access if from either side? Where and how should assets be installed? The best practice I am concocting is that a developer put all assets into ~/Actitivities/MyCoolActivity/ The xo bundle will obviously install and point there. Gnome .rpm installations should point there too. Hopefully it is straightforward to make the gnome rpm installation point and run from this location.

On a dual-boot XO, does it make sense to use the same binary code for sugar activities also in gnome applications? If so, are there guidelines or example acti-plications? If the same binary code is *not *re-used by both platforms, but just the same code base, are there guidelines or examples of how to re-use the same code base effectively? Off the top of my head, how data is serialized is handled differently between the two platforms. This question is of particular concern to acti-plications with many media assets, like some video games. It would be nice to avoid file redundancy.

Re: [Sugar-devel] acti-plications: write once, run anywhere?
The gnome side will most likely be installed via RPMs (or .deb files on Ubuntu/Fedora setups). So your Sugar app could just use the libraries, binaries and resources/assets from the RPM. Examples - Write.xo uses the Abiword libraries. Browse.xo uses xulrunner (the Firefox libraries backend). Bert pointed out EToys. In all those cases, you get code reuse and a small Activity, but the activity completely depends finding the things it needs. If my acti-plication has dependencies that are not part of the underlying build, do I need to install them on the gnome side first? Or can cross-platform libraries be initially installed on the Sugar side too? A related follow-up: does it make sense to put cross-platform dependencies that a gnome activity would need into ~/Activities/MyCoolActivity.activity/ ? ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

question about bad cairo performance on the olpc xo

platforms, redrawing vector graphics is much, much slower than blitzing
bitmaps to the screen.

cairo which retards the performance of displaying images? The same test

Re: Feedback on Measure (was Re: Another pass through some basic Activity test results)
Do you need to do that for each window? Why don't you just listen for that signal in just the main activity window and stop everything when gtk.gdk.VISIBILITY_FULLY_OBSCURED and resume when otherwise? Full screen modes in Record completely obscure the main activity window. We don't just listen for visibility events on the video windows because sometimes these are fully obscured (when transcoding, for example). Therefore we listen on both the main activity window and the video windows, and in consultation with the activity's current state (fullscreen, normal, transcoding), decide if Record is the current activity. I've never fully understood the rationale for why the sugar api does not alert activities as to when they are active or not, thereby saving all activity authors these hassles. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: [sugar] Another pass through some basic Activity test results
In Sugar, there's always one and only one active activity. You can see which it is by looking at the icon below the XO in the favorites view or by looking at the selected activity button in the top frame. This is the activity that will be brought to the front when you go to the Activity zoom level. I'm guessing Measure uses its active activity status to decide if it should update itself or not, but from earlier emails I think the desired behavior is rather to stop updating while the activity window is not visible. For this, the activity author can use the information that the window manager (or is it X?) provides to each top level window, in pygtk: http://pygtk.org/docs/pygtk/class-gtkwidget.html#signal-gtkwidget--visibility-notify-event Just listen for that signal and check the value of event.state, it can be one of gtk.gdk.VISIBILITY_FULLY_OBSCURED, gtk.gdk.VISIBILITY_PARTIAL or gtk.gdk.VISIBILITY_UNOBSCURED. You will want to stop updating the screen when fully obscured and update it otherwise. Faisal, could you please update the almanac with this info?

Re: [sugar] Feedback on Measure (was Re: Another pass through some basic Activity test results)
Is there any particular reason why Record does not use a single window? Record's GUI overlays widgets on top of video windows. This is how we create the picture in a picture effect (using XV in a window) and also how we add the fullscreen toggle button. GTK doesn't play well with overlapping widgets -- gtk.Fixed() doesn't guarantee Z-order. So we use a stack of gtk.Windows without decoration. Unfortunately, when we put xv video into a widget (e.g. gtk.DrawingArea with a gstreamer xvimagesink) into a gtk.Fixed, that widget's video always displays on top of other widgets, regardless of its z-order. It was recommended at one point to create a new version of gtk.Fixed that guarantees z-order, but the use of gtk.Window was well underway and works. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Cerebro: Scalable presence information
eXcellent name choice! On 12/31/07, Polychronis Ypodimatopoulos [EMAIL PROTECTED] wrote: Announcing Cerebro - http://cerebro.mit.edu Cerebro is a scalable, light-weight protocol that allows 802.11b/g devices to form a mesh network. Cerebro has the following advantages: - It provides presence information about 100 nodes using only a single frame per 10 seconds, per node. - It runs on _any_ 802.11b/g device (tested on XO, Ubuntu, Nokia N800) - It can (but not yet) provide routing information within the mesh network that is formed by regular wifi devices. Demo: http://lyme.media.mit.edu:8000/ The simulation running here shows 50 simulated nodes and a real one (shown in the center of the screen). The nodes within the same group are all in range with each other, but each group is not in range with other groups. As a result, nodes within the same group are placed close together, whereas different groups are placed as far apart as possible. All nodes have information about presence and distance for every other node. There are 50 nodes simulated in 8 groups of 5 nodes and 1 group of 10 nodes. Although the presence algorithm scales quite well, the visualization does not scale as well (yet :-). Therefore, only the first 20 nodes are displayed properly, while the rest are simply put in the list on the right. A sugarized version of the UI will follow soon! Enjoy!

Re: Help wanted: video demo!
On 12/11/07, C. Scott Ananian [EMAIL PROTECTED] wrote: We need a demo which shows off the full-screen video capabilities of the XO. Unfortunately, Record compresses its input rather heavily, so it's not a great demo for video playback. We bundle the Ogg Theora codecs, and Browse can play media files full-screen, so the first step is for someone to invest some time in transcoding an appropriate demo movie (I suggest http://www.elephantsdream.org/ -- some ogg transcoding linked from http://wiki.xiph.org/index.php/Elephants_Dream ) to an appropriate bit rate / size for the XO. Make it look good! It may be that we need to find a higher-performance (but still free) codec or some such to make this really look good. Help here could be useful, too. To handle most any digital video format, Quicktime would be easiest to get started. - Encode your existing files into DV (using Quicktime pro). - Use gstreamer to encode into ogg files: gst-launch-0.10 filesrc location=grover.dv ! dvdemux ! dvdec ! ffmpegcolorspace ! theoraenc ! oggmux ! filesink location= grover.ogg Of course you will want to alter settings to change the file size, rate, etc. You would make these changes in the gstreamer pipeline or in quicktime as a pre-processing step. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Help wanted: video demo!
Does Erik's transcoding mechanism work to get it out of RV format? I don't believe there is a real component for a gstreamer pipeline. You would want to use the highest quality originals anyway. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: ip4-address buddy property - still needed?
While I welcome the new activities and think it is great to integrate them into sugar, can we reconsider completely doing away with the dev console? It is /very/ useful to have the console open on an xo while the activity you are debugging is running behind it. Can't you have both the old console and the new activities?

Re: How does record activity the camera in Sugar?
The first command will run the camera data directly to the xv image sink via gstreamer (a video application framework used by the Record activity). We can diagnose where the problem is better when we see the result of this test. The second command will run a test pattern directly to the xv image sink. If we get the same visual problem with the test patter, we might be able to rule out the camera as the culprit. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
