Diego,

if you could work on this, it would be great! I have a lot more urgent things on my plate, unfortunately :/

I think you do not even need the Sugar emulator for testing this. We use a regular i386 Linux Squeak VM (built straight from SVN, now at version 3.9-9), and a costumized image (squeakland-based). The Sugar integration works a lot like the browser plugin.

So if you get it working with our image on a regular Linux PC that would be great. The latest Developer images+changes are at

http://tinlizzie.org/olpc/OLPC-Squeak-latest.zip

But also load updates :)

To really include it, I would need the plugin sources so Ian can put it into SVN, plus a changeset (or more) to put into the OLPC update stream. I have some USB webcams, hopefully one of them will work with V4L so I could test it.

Also, since I did not use V4L before, what else do I have to install?

Bert,

Let me know if you need the sources, not sure if the published sources are the newest.

BTW, Does the OLPC simulator support webcams? In this case, I can try to make it working for myself.

Cheers,

Oh, that looks great, Diego! We'll definitely will try to get it working :)

Hi Folks,

I already hacked a webcam support for Squeak@Linux, it's named "Video4Squeak".

    http://minnow.cc.gatech.edu/squeak/3765

It uses Video4Linux, so I think is posible to run it in OLPC.

The camera also support some toys programming features. I also got working the Intel(Play) USB Microscope (except for the ligth, the linux module seems to be broken).

In the screenshot you can see 2 webcams (in fact is one plain webcam and the Intel microscope) capturing at the very same time.

My work assumes the morph will survive the camera disponibility (you can move the squeak image or a .pr to another machine without camera, or if you connect more than one camera the order in USB stack can be different in different boot-processing, etc) and it makes a good job trying to reconnect.

In etoys vocabulary, you can find a "lastFrame" property. This property answer a SketchMorph that you can embed into a container and create an animation. I used to create a project where one (etoys) script capture a frame between time and time (normally 30 seconds) and put the frame into a container. Another script just plays an animation (using the captured frames) and instantly you have an accelerated-video (this type of videos where a flower grows really fast, etc).

The plugin interface is relatively simple, so it's quiet posible to get (the plugin) working in Windoze.

Attached is an screenshot showing the complete etoys-vocabulary.

Let me know if this helps.

Cheers,

-- Diego

Comment (by jg):

Really cool.

Does Etoys/squeak have support for cameras? We got that running today...

Well, there is "VideoFlow", which looks interesting, but requires a plugin that might not have been ported to Linux yet:

  http://minnow.cc.gatech.edu/squeak/2411

And I just received some old bits from Tim Rowledge which once

formed

a Video4Linux plugin.

How would I access the camera? And until I get a b-test, could this be simulated by a USB camera?
