I do a fair amount of "customization" on every build I install. Therefore the fact that current Opera versions for example want to install something in /etc is no obstacle for me - I just "lump" that requirement with the other "system modifications" I apply (e.g., putting something in /etc to support 'rsync' between XOs)). [I also install the Adobe Flash-10 player onto all the Browsers my XO has.] In any case, I have for a long time been running Opera (currently 9.60) on (F9-based) 8.2 and on (F10-based) Joyride. I launch Opera from its icon in Home view. I do not need to disable Rainbow in order to run Opera. mikus ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Basically the problem is this one from the Opera Wiki page: "There is at present an incompatibility between the Opera activity and the OLPC Rainbow security system on some builds.

My memory's kinda fuzzy, but I think I went straight to the guys at Sugar Labs then asked over there (web form?)... basically the answer I got was that we really can't do much about it because the standard linux desktop version of the latest Opera rpms installs its files to /etc/ and other system directories, and the new Rainbow Security system requires that Activities only install and run from /home/ (olpc/ ?) or something like that, and the only way to fix it was to modify Opera to install/run only from Rainbow-permitted directories and that's not possible outside of Opera's organization because Opera is closed-source. -Naz -- Carlos Nazareno http://www.object404.com -- interactive media specialist zen graffiti studios http://www.zengraffiti.com -- Philippine Flash ActionScripters http://www.phlashers.com ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Hi Stan! > 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, I've documented this problem as well at http://wiki.laptop.org/go/Adobe_Flash -> The XO's webcam is not interfacing properly with Adobe Flash 9 & 10. Adobe's done a lot of work towards getting cameras in various Linux distros working with webcam enabled-Flash apps, and they finally got V4L2 running last year, but apparently the XO is using some kind of not-as-common chipset/software combo (in 8.2.0 I think the OS is using a weird mishmash of old & new software/drivers because of problems with the cam in the webcam activity on newer drivers?). I got in touch with some Adobe guys last year before Flash Player 10 final launched about Flash's webcam interfacing problems on the XO, filed the bug report, followed their instructions and submitted the hardware info gathered from the data-gathering tool at Penguin.swf's (Adobe's official Linux Flash dude) blog: http://blogs.adobe.com/penguin.swf/2008/07/paparazzi_v2_1.html Anyway, I haven't heard a word from the Adobe folks yet as I guess that was a very busy time for them with Flash 10 final release going out the door at the time, the report probly got lost in all the hubbub. Anyway, I'll try following up with them as I'd like to play with writing some Flash webcam toys that would work on the XO myself. >I can't get Flash to activate the > XO's camera... ...This was while running on the XO's Browse activity. The camera works with the Browse Activity, just not properly (the camera turns on and it displays red & green static that reacts to objects waved in front of the camera) > I thought > that maybe Opera for the XO would do better. No luck. Yup, Same as with the Browse Activity. XO's weird camera chipset/software combo interface still hasn't been fixed with the linux Adobe Flash 10 plugin. > Opera as installed from the wiki.laptop.org/opera instructions does not even > play > the Flash on the Adobe web site 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. As documented in the Adobe Flash wiki: http://wiki.laptop.org/go/Adobe_Flash and Adobe Flash The official Opera Activity is based on Opera 9.12 and it isn't compatible with Flash 10. The newest Adobe Flash plugin compatible with it is an older version of Flash Player 9. Newer non-Sugarized Linux desktop versions of Opera like 9.63 latest work fine and dandy with latest Flash Player 10 final. Again, you're going to have to use the Terminal (type "opera" at the prompt) to launch Opera. > 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. Ditto. I've tried Sugarizing newer versions of Opera myself, but we're out of luck because of the Rainbow Security implemented in newer XO OS builds don't allow writing of files by Activities to certain directories that Opera installs to. The Opera dudes will have to create a special OLPC Opera Activity for us like with 9.12 since Opera is not open sourced and we won't be able to do the proper modifications for Rainbow Security compatibility ourselves. > 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? Runs fine and dandy, you just have to launch it via terminal :) -> Launch Terminal Activity, type "opera" at the prompt (assuming of course that you'd already installed Opera). That instance of terminal will then be inaccessible until you exit Opera. Once you exit Opera, you regain control of the terminal prompt. (Yeah Skier, the Opera wiki entries are next on my hit list for editing: they're due for massive updates :P) > Even without the 2-way video streaming, www.vyew.com is a nice > application for collaboration over the Internet. Try it. Thanks for the link Stan! I was looking to build a Flash app just like that, only less ambitious (crud, someone beat me to the punch! ;P) Cheers! -Naz -- Carlos Nazareno http://www.object404.com -- interactive media specialist zen graffiti studios http://www.zengraffiti.com -- Philippine Flash ActionScripters http://www.phlashers.com ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
[Fwd: Problems with Adobe Flash player on the XO.]
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. https://bugs.adobe.com/jira/browse/FP-137 Stan Original Message Subject: Problems with Adobe Flash player on the XO.

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.

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.
