I updated to Win11 24H2 and had no video/gif backgrounds anymore.
Then I re-installed Windows again (as a way to fix this - and other stuff in my Win7-Win10-Win11 install - lazy me) = same result. No Video/Gif Background.

i tested: MP4, FLV, AVI & GIF
i have all codecs installed.

nothing works - desktop is just black 😕

best wishes

i switch from a normal jpg background on both screens to a gif on on screen and an mp4 on the other screen
result is a black background on both screens.

i only logged the bug - so time is 21:02

NOT IN THE LOG: if i add any normal picture to one of the screens instead of gif/mp4 it results in showing the image. but the gif/video on the other screen is still black.

hope this helps

this should be the bug

here the gif

here a video that also doesnt work - like all dont work

by the way: while your at it maybe also include animated webp into "video-background" - as they are significantly smaller than gif

did you find a solution yet?

Hi,

thank you for mostly fixing this issue

mp4, flv and gif works
yet gif has a problem that the "framerate" gets changed to a slower than normal speed. - its like slowmotion

what codec do you recommend for gif?

EDIT: re-installed K-Lite Mega and now it works fine <- NO IT DOES NOT WORK
EDIT2: no it doesnt -> gif are still slide-shows

found the issue:
Win11 24H2 "thinks" its a ARGB32 10fps gif -> while all other players sees them as 25 or 30fps gif
so we have to wait either on AMD/Nvidia or Mircrosoft for a fix
i assume WDDM 3.2 to be responsible for this -> but it can also being displayfusion not reading gif correctly

i also provide some info on how i encoded the gif:
ffmpeg -> fps=25 or 30; use palette; resize output -> works in IrfanView/WindowsPicture/MPC-HC -> does not work with Peek and therefore Displayfusion

EDIT: i was able to "trick" windows to think its a 20fps gif -> i reduced speed to 75% or 66% for several gifs -> those play back faster with displayfusion but slower for any other programm mentioned before

now we are back with NO VIDEO Background again...

11.0.5 works with video background -> 11.1 beta 7 doesnt work

11.1 video background still doesnt work (doesnt matter what file type)
log found here ( https://www.displayfusion.com/Discussions/View/animated-webp-as-background/?ID=0192b92e-0f97-7073-8586-587adf270ce8 )

Just got the 11.1 update today and I'm having the same problem. Tried various formats and sizes on both displays. It's just black. On Win11 23H2.

thanks - gif/mp4/flv work again

Got the lastest update and video backgrounds are working again, no issues.
