paperview isn't working

hi, i've used paperview for 3 month on dwm + void linux, now i've reinstalled it and paperview isn't working. no errors, just not working.

floating point exception (core dumped) paperview . 24

what is error ?

paperview + compositor

Hi glouw, looking through the discussion on the non-SDL2 gist you link in the readme. I may be wrong but I'm pretty sure that if you did go down the route of using the XRender extension instead of SDL2 that this compositor issue might go away. Perhaps you could make a non-sdl2 multi monitor version of paperview using XRender instead of SDL2 and see if this works?

Doesn't work on Manjaro.

When I try to run the ./paperview command I get a "[1] 280403 segmentation fault (core dumped) ./paperview scenes/train/ 5" error...

Not working in Ubuntu 20.10

Hello.

Just compiled it and ran it on a fresh Ubuntu 20.10 install. The program is running and I could confirm that it is running the rendering functions, but the wallpaper doesn't change from the system set one.

Is it not supported? Maybe Gnome gets in the way?

Does not work with compton

first of all, the project is really nice, works even in a vm without problems...
but...
it does not work while compton is running.
since it hasn't commented anything in the code, i haven't figured out how it works... (well, i'm probably not very good in c...)
but i guess that it does not draw on the rootwindow...
if it would draw directly to the rootwindow it should work (I had a script which did exactly that and it worked -> but cpu on fire)

(i'm probably not very good in english to..., sry 4 that... xD)

---

my test-setup:

vm with 8gb ram and 16 threads (r9 3900x)
debian 10.5.0
linux 4.19.0-10
i3wm 4.16.1
compton 0.1~beta2+20150922
(wallpaper set with feh -> survives paperview)
make 4.2.1
xorg 1:7.7+19

Is there any way to support videos?

Curious if this could be done as converting even just a 30fps video loop to bmps is a bit much given the amount of data you end up with

Video Loop: 30 sec., 30fps
mp4: 3,7MB
bpms: 5,58 GB

While many are probably fine with pixel style low fps loops, I personally can't stand it ':D

doesnt work on xfce unubntu 20.04 for me

I buddy! I compiled your software and tried to make it work, but it just doesnt display anything. how i could debug why isnt doing anything. it just, runs..but nothing at all..

I made a bunch of bmp from your example, place it inside a folder eample then try ./paperview example/ 3 &
just to try something..
what i am missing here?

Not working on i3wm.

executing ./paperview train 5 just seems to refresh my monitor and doesn't change the wallpaper. Clip here
. Its a Thinkpad T450 with an integrated intel GPU if that helps.

can 't run at win 10,could you help me?

Multi-monitor support?

Is there anyway to set different wallpapers for different monitors? I have a setup with two monitors that don't share the same resolution and the program doesn't seen to know how to deal with it.

any build for macOS?

Hi team,

You can shared a binary for macOS

Working Compositors?

Are there any known compositors that work with Paperview? I'm working on a rice that utilizes this, and I want to use a compositor to really emphasize this program, because it's stinkin' awesome!
I've tried Picom and Compton, and as I expected, both failed.

Thanks in advance!

Pause Rendering

Would it be possible to use SDL_WINDOWEVENT_HIDDEN and SDL_WINDOWEVENT_EXPOSED/SDL_WINDOWEVENT_SHOWN to pause rendering when the background isn't in view, and so save same cycles/battery?

I think it might work during the poll loop watching for the quit event, at a glance.
