Sony Bravia TV display off screensaver

April 11, 2017, 2:53 am

I developed a screensaver plugin for Sony Bravia Smart TV's which will turn the display off when the screensaver kicks in. This will reduce the power consumption in my case to about 18W instead of normally 30-60W
Tested on a 2015 Sony Android TV. In this case, you probably have Kodi running on the TV which makes it hard to fill in the pairing code. You can use the Kore remote app or something else that won't directly talk to the TV. I found it's also possible to do the pairing on another device with Kodi.

The plugin can be found here: https://github.com/ksya/kodi.screensaver.sonyscreenoff

I know I can probably improve my code, which I will do later..Or just submit a pull request!

Let me know what works and not.

Binary vs Python implemented visualizations

Hi All,

Just a quick question. It seems that all the visualizations are implemented as bynary add-ons rather than python add-ons. Is this mandatory? Could i write my own visualization as a python add-on? If so, are there any examples of this i can look at?

Visualization.spectrum Client returned bad status (4)

Hi,

I'm trying to package the spectrum addon for Fedora and am encountering an issue that I'm finding difficult to debug. So I'm building from version 1.1.1 of the addon from this commit: https://github.com/notspiff/visualizatio...631c2f8115 .

The build goes smoothly and shows no errors, however when I load it up in Kodi I get an unknown error. Literally the only thing in the debug log is this line: "22:07:03.628 T:140040623103808 ERROR: ADDON: Dll Spectrum - Client returned bad status (4) from Create and is not usable"

All libraries and resources are getting pulled into the package:
Code:
[root@kodi01-dev01 temp]# ls /usr/share/kodi/addons/visualization.spectrum
addon.xml  addon.xml.in  icon.png  resources

[root@kodi01-dev01 temp]# ls /usr/lib64/kodi/addons/visualization.spectrum
visualization.spectrum.so  visualization.spectrum.so.1.1.1  visualization.spectrum.so.17.1

All permissions seem correct:
Code:
[root@kodi01-dev01 temp]# getfacl /usr/lib64/kodi/addons/visualization.spectrum/*
getfacl: Removing leading '/' from absolute path names
# file: usr/lib64/kodi/addons/visualization.spectrum/visualization.spectrum.so

# file: usr/lib64/kodi/addons/visualization.spectrum/visualization.spectrum.so.17.1
# owner: root
# group: root
user::rwx
group::r-x
other::r-x

I'm really not sure how to begin debugging this - I'm really keen to figure this out myself, but could someone give me a few pointers as to where I might begin?

This is the build segment from my spec:
Code:
cmake \
  -DCMAKE_INSTALL_PREFIX=%{_libdir}/kodi/addons/ \
  -DCMAKE_BUILD_TYPE=Release \
  -DBUILD_SHARED_LIBS=1 \
  -DUSE_LTO=1

Screensaver development

Noob here -
Expert programmer, but need some sort of 'thread to pull on' in order to develop a new screen saver.
Have looked at both the Git repositories as well as brief search of the forum, but haven't figured out where an example screensaver might be.
Currently use the picture slideshow screensaver, so if I can find the source to that one, would be happy enough to start.

Any pointers would be appreciated (even things like "you're an idiot - here's the link to where you should start")

Thanks in advance.

Screensaver time if playing audio (Current Screensaver as Visualization add-on)

I'd like to launch my current Kodi screensaver immediately (or with a custom 5-10-30sec delay) on music playback.
Such a slider in "Settings->Interface->Screensaver" would be nice.

Found similar threads about a fireplace or background music with screensaver, but, guess what? No solution in this forum yet Smile
Seems, the main difficulty is no python in viz support = C++ coding required. In Python it could have been straightforward xbmc.executebuiltin("ActivateScreensaver").
Anyone to code universal solution?

My actual screensaver is Turn off LG TV (particularly on music it does turn off LG screen via keymap or after 10 minutes, while AV-receiver continues playback).
A simple "Dim" as visualization will fit too.

Linux - v18, no visualisations / screensavers work, projectM crashes

May 8, 2018, 2:40 pm

I built kodi v18 from git master along with the included version of projectM
hardware is a kaby lake  i5-7200U

there may be 2 different issues here but I'm not sure.
first: projectM crashes with
Code:
undefined symbol: _ZTI5Shape
like in https://forum.kodi.tv/showthread.php?tid=305558
so I tried the fork @ironic_monkey did but the error stayed the same.
I followed the build instructions closely and copied the resulting visualization.projectm.so.2.0.0 into /usr/local/lib/kodi/addons/visualization.projectm/visualization.projectm.so.2.0.0 so kodi could see it.


second:
goom, shadertoy, wave form, etc. all that came with kodi don't work safe for spectrum.
there is no error, not even in the debug log (at least none obvious to me)
it just show anything besides the blue/greenish shady background of the default theme.
spectrum shows jumpy columns.

also dim is the only sceeensaver that works. selecting an other one results in a black screen with the mouse pointer in the middle, there is no going back from that.

here's the reason why I compiled kodi v18 instead of using the one that came with debian testing: https://forum.kodi.tv/showthread.php?tid=331170

logs:

Code:
root@kodi:~# cat kodi_projectM.log | gist-paste -d 'projectM'
https://gist.github.com/50eafc0bd9e345ed...177c05a2d6
root@kodi:~# cat kodi_goom.log | gist-paste -d 'goom'
https://gist.github.com/beb674267400547f...a07f4f8f92

now I'm out of ideas Undecided

btw: has the GLEW / EGL patch been added to the original source? seems reasonable to me to do so as it is supposed to fix issues on intel hardware.

I just uploaded an example Add-on for new screensavers, its pretty simple and based on Sphere's old test Add-on that has been broken for a while.

I updated it and added a nice background.

SOURCE: https://github.com/zag2me/script.screensaver.example

Hopefully this will help any new developers start making some new Screensavers. My motivation for this was to write some more Wiki Tutorials for each Add-on type in Kodi.

I'll write up the tutorial here soon:

I’m running Kodi 18 on iPad. I want to customise the background on the standard skin. I installed the Google add on and tried to do a picture search/download, but any images I tried to save all say failed to save. I can’t seem to add to any directories (only have home and inbox as standard) can’t seem to link to where images are stored on my iPad either.
Any solutions?

How to get visualisations working on Android TV?

I've got KODI on Android TV, but visualisations stopped working about a year ago.

TBH, I can't even see where to enable them, I've got shadertoy vis installed, but can't seem to run it.

I can run projectM (the standalone vis) from the Android Apps part of KODI, but I'd like the integrated vis to work really.

I'm pretty sure about a year ago these did work.

Need help with disappearing image control

January 12, 2019, 1:44 pm

I've been working on a new screensaver: https://github.com/robbieh/screensaver.embellir

But I have a problem where one of the image controls is disappearing when the screensaver is first installed. I'm in a fortunate position that I have a collaborator and I can test this on my laptop, his laptop, my dedicated Kodi, and his dedicated Kodi. Three of those are Linux devices, and his laptop is Windows. In both cases where I've installed the screensaver on the deciated Kodi boxes via a zip file, it sort-of works but the main image control is missing. After I restarted Kodi on my dedicated box, it began working. But it hasn't on his. Also, in some cases it seems the image pops up but then either disappears or else falls behind the background image".

All of these are Kodi Krypton 17.6.

I'm hoping someone can point me in the direction of some things to look at. The event log isn't saying anything interesting (pretty much just " CSkinInfo: failed to load skin settings" which seems to happen all the time even when it works) even when debug logging is on.

Thanks in advance!

v17 - "Blinking" image when loading image from URL with setImage()

January 16, 2019, 2:43 pm
$

0
I'm loading different images via HTTP from Python by calling .setImage('URL') on a controlImage object. The result of this is that the image disappears and then the new one is loaded into it's place. This causes the image to sort of blink or flicker. I've looked for a way to avoid that, but can't find one. I wanted to ask if I'm missing something obvious before I try to do some sort of trick that switches between two different image controls.

Thanks!
