FFMPEG.EXE System Error

[potesd]

"The Code execution cannot proceed because open264-6.dll was not found. reinstalling the program may fix this problem."

I get this error constantly during the rendering animation fram 27 of 30, when "./output/out_%05d.png -> ./output/out_%05d.mp4.

I've tried manually adding the DLL, and nothing seems to work, any tips or tricks?

Looks like a video codec for h264 missing issue maybe reinstall ffmpeg? run command like "conda install -c conda-forge ffmpeg" Or install a video player such like VLC
