Kweb Suite (Minimal Kiosk Browser, omxplayerGUI)

[gkreidl]

No, not really. But there's a trick I'm using in omxplayerGUI for the popup menus: If you can catch the mouse event, when it enters a video area, you can set the transparency to 50% (128), end reset it again to 255 when the mouse leaves the video area.

I had the same idea and I tried a little permanent transparency on the video, with a white background under the video. It works, but when in full screen I need to have the cursor on the video too (to be able to click on some part of the video), and the true video without transparency.

But unfortunately, it seems it will be impossible ?

You could try to catch a simple mouse click anywhere and use it to return from full screen mode.

[nlc]

No because the goal is to be able to click on specific zone of the video to generate events on another raspberry (with ajax calls).
If the cursor can't be visible, I think I am in a dead end

Hi,

The 'debinstall' script that is included in the kweb 1.7.9 tarball has this line:

sudo apt-get -y install gdebi-core

There is no package by that name available from apt-get:

sudo apt-get -y install gdebi-core
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package gdebi-core

What is the resolution, please?

Thanks.

[tree]

Never mind. Bad package list.

Thanks,

kweb working great for me, other than ability to log in to services such as webmail, or anything that require a login.

Any ideas? Thanks

Did you enable Cookies?
It might also be a good idea to disable private browsing (on the configuration page).

no luck so far... any other ideas?

No idea. I'm logging into quite a number of websites and have met no problems so far.

I've just published the first Stretch version of the kweb suite.

The hardware accelerated webkit3 engine (created by the Foundation to be used by epiphany) is not available on Stretch and so there is no need for two kweb versions any more. Both browsers have been merged into one (kweb), which now uses the GTK-3 interface.

Because python-pip is working again on Stretch, the installation of youtube-dl is now done using pip automatically during installation of the kweb suite.

The installation process has been simplified and a few scripts have been removed.

The dependencies now include python-pip and uget and git has been removed.

The kweb manual is not up to date yet (still version 1.7.0) and will be updated in version 1.8.0.

had a Omxplayer-gui setup file, which /path can fine it from jessie to copy to stretch.

Everything (e.g. bookmarks, presets etc.) is in

i'm using kweb 1.7.9.8, and i've found out if i close youtube-dl server in the kweb

it seems like kweb didnt close connection properly.

Code: Select all

pi@raspberrypi:/usr/local/bin $ sudo lsof -i:9192
COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
kweb    2869   pi   13u  IPv4 216816      0t0  TCP localhost:51128->localhost:9192 (CLOSE_WAIT)

so i need to kill it manually.

and does kweb support youtube subtitles/closed captions?

Similar things happens with all web browsers, just check it with "netstat -t -W -p", If you want to avoid it in this case, run the youtube-dl-server in embedded mode by starting omxplayerGUI.

and does kweb support youtube subtitles/closed captions?

Perhaps within the browser, but I have never tested it. But definitely not when playing web video with omxplayerGUI.

Dear gkreidl,

I try to launch command on the raspberry with kweb through links int the Web page, but it doesn't work, I don't know why.

In my .xinitrc I have :

Code: Select all

matchbox-window-manager &
kweb -JXLKR6 /home/pi/controlScreen2/index.html

In my web page, I have this link :

Code: Select all

<a href='file:///homepage.html?cmd=sudo%20pkill%20kweb'>link</a>

I try to kill kweb to do a test (my true need will be to move the cursor on screen with a xdotool command). But nothing happens when I click on the link.

I set X and L option, should I do anything more ?

Regards,
Cyril

If you are starting with a file outside of the protected area (within your home folder, for example), command execution is disabled by default. Add "C" to your options string: kweb -JXLKRC6 ....

I think it's the case, I use a system command (located in /usr/bin). I tried the C option and now it works well, thank you very much !!
I looked in the documentation but I have not found the C option, it's why I have not tried it

I have a couple of questions:

1.) Will this affect any of the files, programs etc. on my system when I install this?
2.) Can I ask what is the size of Kweb Suite?
3.) Is it working fine now in Stretch?

1) no
2) Package size is slightly over 4 MB and and most of this is used by the two PDF manuals.
Some additional shared libraries may be installed, but this depends on what you have installed before.
gdebi-core is installed by the install script, because it is the needed for package installation from .DEB files.
Two additional programs are installed: uget (a great downloading tool) and youtube-dl (using pip for installation).
3) Yes. I've discovered one problem so far: Flash support (using a special wrapper for pepperflash) doesn't work, because it is not compatible with GTK+3. I'm considering to switch back to GTK+2 in the next release.

Hello,

I have a question about a example of use. To check if it's possible to solve my issue with kweb.
The kweb is very powerfull tool and can use for lots of use cases. Too much cases for a fast overview.

I would like to play a audio/video-stream in omxplayer fullsize (hw accelerated) and overlay a webcontent (Fullsized, F11) with alpha-channel over the video, so you can see the video through the Homepage. The Webcontent is specialwebsite with only alpha-channeled content.
It should be possible to remove the webcontent, so you can see the normal video.

Can I configure kweb for my mentioned above scenario.

Many thanks for your feedback

[tvjon]

This is actually easier than your previous request, to which I replied, where you talked about two displays.

Kweb doesn't need to be involved.

I don't would like to give the video a transparency.
I would like to give the browsercontent or the whole browser a transparency because this content is over the video.

My problem to your first hint is that the white background of the browser which is over the video should be replaced to a full transparent background. The white color of the example image should be transparent.

I give you a screenshot from an other system where it is running according my descriptions.

The transparent menu is a website over the whole screen.

[nlc]

You want to do the same thing I wanted to do some week ago. That's not possible to have the browser over the video. My need was to have a text input over the video, but that's not possible with kweb / omxplayer.

[nfstoney]

How did you solve it?

[nlc]

I separated the display in 2 zones, a 150px zone on the top of the screen, with the input text, and the same background than the video.
And I modified the video to remove the 150px, and I play it in the bottom of the screen. Fortunately, the top of the initial video was a fixed part, and here is the result :

https://www.youtube.com/watch?v=z8Ix71DoglA

[nlc]

The white part on the bottom and on the right is because the final application run on a 1366x768 screen, and mine is 1920x1080

Hi is it possible to use this browser in kiosk mode? I guess that the answer is yes.

But is it safe? I don't want the user to be able to access my system when its in kiosk mode.
I just want my user to be able to browse my web page that all.

How to hide all button, address bar?

Is it possible to show a virtual keyboard?
