Video wallpapers are a feature I would like for KDE, so I definitely support this! I see it hasn't been updated in quite a while however, so I doubt it will work with Plasma 5. Does anyone know if the addon is compatible with the latest version of Plasma Desktop?

It's also not compatible with the new version of ffmpeg (some functions that used to be deprecated have finally been removed).
It's too bad, that thing here looks quite awesome.

It's possible to Compile, I've done it,
BUUUUUUUUUUT it crashes a lot. It's for playing not for working.

Awesome except it uses huge amount cpu power so for now its kinda useless, great program/plugin but need to be fixed

http://aur.archlinux.org/packages.php?ID=50401

But seems that this package was abandoned... very sad. Would be awesome if it would use vdpau and also use CPU not so intensive. When I watch some video in VLC it's take about 2-5% of my CPU, but if I try the same video with this extension it will use all 100%.

But still, this is an awesome idea for addon, try it with these videos:

Hey
on slackware13.1 (with kde 4.5.5) after installation I cant choose a video file for play. the same like in the wallpaperclock, but there i can paste the file to the directory where the system saves wallpaper clock,

/home/danielo/.kde/share/apps/plasma/clockwallpapers/

and its ok. I got the wallpaper clock.

So is there any chance to set the video manualy in system files? Please help.
I tried with mplayer and xwinwrap, but it sucks.

Excelent!!!! The installation was dificult but worth it :), great.
Thanks,

Where I can find videos or presentations such as the Youtube video?
Thanks.

http://blip.tv/file/get/Nowardev-AnimationKubuntuLogo649.avi

this is the videos i have rendered there is the project , blender project if you have a strong computer you could render a longer video...

you should try:

xwinwrap -ni -o 0.3 -fs -s -st -sp -b -nf -- mplayer -wid WID -quiet '/path/to/video/files/*.avi' -loop 0

The link for the Mandriva package is broken. Can you fix this please?

on fedora system's you need to
su -c 'cp -r /usr/include/ffmpeg/* /usr/include/'
before compiling
I am building an RPM for this
but there are in the new version
of sws_scale some changes and build fails

error: initializing argument 2 of Б─≤int sws_scale(SwsContext*, const uint8_t**, int*, int, int, uint8_t*

from line 404 in vid.cpp
pls fix it

Video option shows up in config but no file selection dialog

here is screenshot
http://imagebin.ca/view/chkC6fji.html

any advices? i had tried to reboot computer..no changes

i have made a package for kubuntu with cpack with this way :

http://nowardev.wordpress.com/2009/12/27/how-to-create-a-debian-package-for-script-and-for-project-that-use-cmake/

download link

http://www.mediafire.com/?nob5m4mmuix

i have tested on my system and it's working fine

it's pretty simple to do :)

that sick wordpress doesn't recognize the correct stuff

i hate that every time it replace

-- with -

I L-O-V-E the idea but... done install and nothing changed :(
I don't have an option to choose a video in display properties window, just image, slide show and color...
Kubuntu 9,10 64bit with KDE 4.3.4

That's what I get when I try something from the other post:
Quote::~$ ls /usr/lib/kde4/wallpapervideo.so
ls: nie ma dostępu do /usr/lib kde4/wallpapervideo.so: No such file or directory

:~$ cat /usr/share/kde4/services/video.desktop
cat: /usr/share/kde4/services/video.desktop: No such file or directory

:~$ kde4-config --prefix
/usr
Maybe it's because of:
Quote::~$ make -j3
[ 0%] Built target wallpapervideo_automoc
[100%] Built target wallpapervideo
??
plz hlp ;)

Solved.

I used cmake line from http://nowardev.wordpress.com/2009/09/19/video-for-your-desktop/ which is a bit erong.

There is:Quote:cmake . -DCMAKE_INSTALL_PREFIX=`kde4-config –prefix`

Should be:Quote:cmake . -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix`

Runs slow but I'm gonna get some raw avis and we'll how it's going to work then.

Cheers ;)

Would be nice, if you could include the version number in the tar archive, because of packaging purposes.

m0nk

sure. tell me what to write.

Probably a dot-release, so plasma-video-wallpaper-0.1.tar.gz to start with, and then when you make:

minor changes - add 0.1
major changes - add 1.0

for example:
plasma-video-wallpaper-0.2.tar.gz
plasma-video-wallpaper-1.0.tar.gz

This is very cool - Imagine a nice easy KDE4 video playing when you log into your desktop for the first time, or many other possibilities.
Unfortunately really cpu-low cost movies are choppy in fullscreen - seems like it is repainting every frame.

Would you be interested in helping with improving Phonon::Experimental::VideoDataOutput? It should be able to export video to you frame-by-frame, very efficiently (for an example of the idea, look at kaffeinegl in kde's playground, under multimedia, or at Zack Rusin's Quasar that Matthias Kretz modified).
I know the mplayerthumbs app uses it for exporting single frames for thumbnails, but you might be able to use it for this too.

The API is still in Phonon::Experimental, and I don't think there's working support in Phonon-GStreamer yet, but it works pretty well with Phonon-Xine.

what can i do to improve it? I just used libav here.

What would be great is if fscking KDE didnt do software scaling when blitting these wallpapers so i can do cool stuff. SDL is super fast and KDE not... there shouldn't be much difference

maybe a good idea is to use opengl and render to a fullscreen quad and then give that fullscreen array to qpainter? can any kde devs confirm this?
