I followed the tutorial of https://www.nextdiffusion.ai/tutorials/how-to-install-ffmpeg-on-windows-for-stable-diffusion-a-comprehensive-guide, Im really stuck in this situation, I tried to search on Google but at least for me I had no luck, any help is more than welcome.

I have run into this same issue. I have uninstalled and reinstall ffmpeg and have followed various bits of guidance online to ensure that ffmpeg is accessible by the application but have not had success. Any assistance is appreciated!

I am able to export as a gif or webp but cannot export as an MP4: stream = output.add_stream('libx264', params.fps, options=options) File "av\container\output.pyx", line 62, in av.container.output.OutputContainer.add_stream File "av\codec\codec.pyx", line 179, in av.codec.codec.Codec.cinit File "av\codec\codec.pyx", line 187, in av.codec.codec.Codec.init av.codec.codec.UnknownCodecError: libx264

Same problems here. I have no idea how to solve it.

Same problem, but the code is a little different:

Error occurred when executing ADE_AnimateDiffCombine:

I can export git and webp, but other than that I get all the errors：
