Hope these tools are good
by anonymous on Monday 31/Jul/2006, @13:39

some KDE apps feels like "under construction", for example kmplayer and/or kaffeine.
Everything is sooo jittery, especially with Konq as a web browser and kaffeine or kmplayer as video plugin.
Or the stand alone players: if I move the video, I saw a blue frame when I move it.

I'm testing Ubuntu and Kubuntu. I use Ubuntu a long time and wanted to know, how Kubuntu feels. Sad.

But this is not the only one example. Only Amarok and K3b feels stable as a rock.

> if I move the video, I saw a blue frame when I move it

welcome to video on x.org. this has nothing to do with how the kde video players are written.

what's happening is that they are rendering using the (speedy and flexible) x video extension (xv) which renders into its own buffer which is then copied into the window. xv is not aware of window movements and so these two events are not synchronized and what you get is some the "empty" xv buffer copied (which happens to be blue) until xv moves the position in memory it is rendering to.

to see this for yourself try using a command line player like mplayer. when you do `mplayer -vo xv myfilm.mpg` and move the window around you'll see the blue. then do `mplayer -vo x11 myfilm.mpg` and observe the difference.

this is yet another area where composition management will help us out a lot in the future. but let's not blame the kde app authors for a problem they didn't create nor can they really fix.

oh, and p.s.: what the hell did that have to do with kwebdev and the cool new hotnewstuff integration?

p.p.s: go kwebdev! great software, and i'm glad to see you back around again eric... i was getting worried.

You're not getting rid of me that easy Aaron. ;-) I'll probably be ambulatory for a few days even after I'm dead due to my dogged persistence. For now I'm working on turning back the biological clock. If I can get to where Adam Sandler is fresh and funny again...

Well not with nvidia binary drivers. I know you shall not use evil binary kernel drivers:) but I put much hope into

http://nouveau.freedesktop.org/wiki/

I really would love to see my desktop being completely free, accelerated and beautiful.. well lets see how can I be of help...

Would you happen to know what option to enable to fix this with the binary drivers?

I had them working (through no known effort of my own) on Gentoo, but when I switched to Kubuntu, the blueness was back, and I hadn't been aware of what went wrong until now.

Thanks in advance.

Blue frame behind video
by Maarten ter Huurne on Monday 31/Jul/2006, @17:17

I thought it is inherent to the way overlays work: the application draws in a solid colour with one particular RGB value and the video card replaces that RGB value by data from a separate VRAM region. If you try to take a screenshot of the video app, you will get blue instead of the video. Correct me if I'm wrong though.

Still, it would be useful if the coordinates of the overlay could be coupled to the coordinates of a window, to make sure you never see the blue.

Yes, it's problem with KDE and/or Qt. On Gnome, GTK (XFCE) there IS NOTHING. So don't say anything what's wrong and code something for the problem.

Well Quanta has one the LinuxQuestions.org user poll for best web development tool the last three years running. Since 2002 we've had Andras Mantia sponsored full time and his priority has been clean development. So For an application this size Quanta has consistently been among the lowest open bug counts of KDE applications. We have a number of converts who had been running the $500 Dreamweaver package on Windows who say for PHP development there is no contest an they'll never go back. I run the development version all the time, never the release, and it has crashed, but I don't recall the last time.

As for Kommander, the editor is based on Qt Designer and is very stable. The executor is only like a 121K binary. Not only that, the scripted dialogs it creates are inherently highly stable because the user is not doing any of the traditional elements of GUI development based on code that are high probability causes of errors. The whole GUI is generated from XML which is generated from a visually drawn interface. So even what total newbies produce is rock stable, and BTW we have people who have never coded before writing front ends to command line programs like Katiuska.

Aaron answered the question about graphics, which has really nothing to do with whether the application is stable, and as the applications you mentioned are built on the same libraries I see no potential problems with ours.

Windows Support
by anon on Monday 31/Jul/2006, @22:44

Hello, Sorry if this has been answered before.

I know that your primary goals aren't to be a windows program, but I am wondering if this is ever going to happen now that QT for windows is GPL? Also, now that KDE4 is coming out for windows, and I saw recently on my free Kubuntu CD's that it comes with Korganizer for windows, are there going to be more killer apps ported over to windows..

This might sound silly to some people, but for those of us who primarilly develope websites on windows (mainly because that is the main target of users) Quanta could be THE killer app for me..

I'm sure there are others who would agree, and others who would be against it, but I just thought it would be nice.. if you ever find the time :)

Thanks! Keep up the good work!

Yes it could, especially if we pull of Object Templates and the new user interfaces, or if you happen to develop with PHP. Running windoze for that reason? VM Ware is offering a free runtime and there are open source solutions to create your partition so that for exactly zero dollars (other than your existing Windows license) you have Internet Exploder there at the ready to see how it chokes on today's CSS. Problem solved. Now you can also get online without becoming a spam zombie in 3 minutes. ;-)

> I know that your primary goals aren't to be a windows program, but I am wondering if this is ever going to happen now that QT for windows is GPL?

I've answered this question before. I really hate Windows, and for very good and practical reasons. Not the least of which is that to date developing a Windows version of Quanta would torpedo all ongoing development, the tools would cost our team thousands of dollars, and we hate they way they do things. However with Qt 4 being GPL on Windows it's my understanding that people will be porting the KDE libraries pretty much out of the gate. Since Quanta is GPL I not only have no objection to it being made available on Windows, I have little I could do to stop it. I'm sure it will happen... I just won't be the one doing the work. However in theory it should probably be like compiling Quanta on BSD or OS X. As long as we follow KDE guidelines it should work with little or no patching.

I'm happy it will be there pragmatically because it will expand our users and move more people to more sane development models. However it's like VM Ware, it makes a lot more sense to run your Windows programs under Linux than the other way around.

That's probably why those are both still beta. Neither is an official KDE app and neither has gone 1.0 yet. You can change to x11 output in Kaffeine using the "xine engine parameters" dialog and changing the video output setting, which will get rid of the blue frame at a performance cost.
