Regarding my prior message, I just found this bug report at Adobe
regarding camera not working with FlashPlayer on Linux, but it says
that FlashPlayer 10 should resolve the problem. Apparently it didn't
on the XO. |

Hi, I'm having problems: Adobe FlashPlayer doesn't detect the XO's built-in webcam so it can't transmit video out to the Internet on Flash-enabled web sites, and the Adobe Flash player on the XO freezes the popup right-click control panel. Gnash didn't work at all with a Flash-based web site we're interested in, so I went to the real FlashPlayer, latest version.
I've been lurking here watching the comments on Gnash versus Flash while I tried to get my wife's XO playing nicely with a Flash-based RIA (rich internet application) site called www.vyew.com . (That's pronounced like "view".) Vyew is a collaborative whiteboard application with video, voice, and text chatting features in addition to the whiteboard. By whiteboard, I mean that several users can connect to the same page and collaborate on drawing sketches and typing text on the same screen, which is visible to all of the connected people. They can also activate their camera and microphone (if they exist) to carry on two-way conversations like Skype. She wants to use this for a remote tutoring activity where she interacts with students about math problems. We tried to get Paint and Colors activities to play nicely with various Sugar emulators (LiveCD, Sugar on Ubuntu, Sugar on Windows Vista) but they all had various problems seeing (presence detection) or collaborating. So we found this web site, Vyew. The Vyew site didn't load the Flash content on the web page with Browse and Gnash, so I installed the real Adobe Flash player on the XO. We have been largely successful with Vyew and Adobe FlashPlayer on the XO. Both computers can see each other's drawings collaboratively on the same page, but we ran into one problem that relates to Flash on the XO. The XO browser can see the webcam video stream from our Dell laptop running Vyew on the Dell's Vista browsers (MS IE & Firefox) and can hear the audio stream from the Dell, but I can't get Flash to activate the XO's camera. When I right-click on the Flash box in the web page, the Flash popup menu appears. I click the "settings" item. Adobe Flash Player control panel pops up as it should, but it is just frozen. I can't get it to flip to the other tabs to set the camera & microphone permissions. In fact, the panel won't even quit when I click the Close button. Nothing gets rid of it except reloading or leaving the web page. This was while running on the XO's Browse activity. I thought that maybe Opera for the XO would do better. No luck. Opera as installed from the wiki.laptop.org/opera instructions does not even play the Flash on the Adobe web site: www.adobe.com/products/flash/about , nor any other Flash embedded in a web page. All that Opera shows is a gray rectangle where the Flash should be, no text saying to click to play the Flash. This is apparently a problem of Opera not interacting well with FlashPlayer, because the Opera plugin directories point to the very same plugin program file by symbolic linkage, so it's not a bad plugin file -- the Adobe plugin plays the Flash .swf embedded element with Browse, just not perfectly, but Opera doesn't play it at all. I submitted a comment to the Opera programmer who maintains the Opera blog about the OLPC version, but that blog has had very little activity in the past year so I'm not hopeful of any results from the Opera people. Has anyone here tried to run a recent release of Opera on the XO, not the very old version that was customized for the XO according to our wiki? For the record, here are the various versions I'm running: XO has build 767 of Sugar, the XO is one recently received from the G1G1 program through Amazon, the FlashPlayer is the one recommended on the wiki.laptop.org page: http://fpdownload.macromedia.com/get/flashplayer/current/flash-plugin-10.0.15.3-release.i386.rpm , the "about" Flash page reports the correct release 10,0,15,3 and so does the README in the flash-plugin folder on the XO, and uname reports that my XO's Linux version is 2.6.25-20080925.1.olpc.f10b654367d7065. Even without the 2-way video streaming, www.vyew.com is a nice application for collaboration over the Internet. Try it. Stan Sokolow
