Some video wallpapers not working

[Hardcrafter]

I have some video wallpapers that work perfectly that I downloaded a few months ago but I just downloaded some new video wallpapers that won't display at all. Not even a black screen shows up.

My Laptop:
Windows 10
8GB RAM
Intel i7 Processor
nVidia GeForce 840M

Sounds like a codec issue, if you have any "codec packs" installed, try removing them. If that does not work, right-click on Wallpaper Engine on Steam and run "Launch scan for conflicting applications". If the program shows you any issues, please solve them. Otherwise, there is a "Save Full Log" button in the tool, please click that button, save the log file and copy-paste the complete log file to www.pastebin.com so that we can have a closer look.

I've never heard of codecs, but I'll try scanning for conflicts.

I tried the scan and this is the log I got: https://pastebin.com/d3cMbPTQ

Unfortunately that's rather inconclusive, could you also paste the main Wallpaper Engine log file to pastebin and share the link here? It's located at "C:\Program Files (x86)\Steam\SteamApps\common\wallpaper_engine\log.txt" (your Steam directory may be in a different place if you have installed it elsewhere.)

Can you completely close Wallpaper Engine (right-click on Wallpaper Engine in the tray and click on "Quit") and afterwards right-click on Wallpaper Engine in Steam and there on "Launch Wallpaper Engine 64-Bit"? Make that Wallpaper Engine is definitely not running anymore before launching the 64 Bit version, otherwise it will simply re-open the 32 Bit version.


If the steps above do not solve this issue, you can try and play the workshop videos manually with Windows Media Player (it's important you use Windows Media Player and no other software). If the videos do not work with Windows Media Player, something is definitely wrong with your general Windows setup. The workshop videos are in this folder:

C:\Program Files (x86)\Steam\SteamApps\workshop\content\431960

If you have installed Steam in a different place, the location may differ but the last part will always be the same. In the "431960" folder you will find more numbered folders, these are the workshop IDs and they contain all the videos, simply look for the broken ones in there and see if you can play them with Windows Media Player.

I've got my main log and it looks like I got a lot of failures
Here's the paste: https://pastebin.com/6N7YGFrj

Hm, can you try installing LAV Filters? We wrote a guide on that here:

Apologies if it's all a bit complex but this is a rather unusual issue but this may fix it.

Just for the record, the error comes from the Microsoft Media Foundation, which is basically a part of Windows responsible for playing videos:

Failed opening video (Media Foundation): C:/Games/Steam/steamapps/workshop/content/431960/1414493679/1529200006_WGlwecv2qgFybrNmQ_Source.mp4

That's why installing the LAV Filters might fix this problem.

Also I tried playing some of the videos through Windows Media Player it said either the format is unsupported (which it shouldn't be because it's a MP4 file) or the codecs aren't supported

[Tim]

Yeah, definitely try installing the LAV Filters from above and report back if that fixed your issue. You may need to restart your Wallpaper Engine / PC.

[Hardcrafter]

It fixed the problem for one of the videos that wouldn't work but there's one specific one that Windows Media Player just won't play whatsoever with no specific error code, specifically Zero Two - Darling in the Franxx wallpaper by Abz.

Nice too see developers actually fixing/doing something useful <3

Worked for me too on a different error. I was getting several errors when trying to upload mp4 video to a wallpaper editor. Installing latest LAV and restarting and setting media to LAV fixed it.
