The ffmpeg core is not in the core downloader list any more and i lost my retroarch build when my pc crashed. Does any one know where i can get the 64 bit windows 10 ffmpeg liberetro core at? I can not find any downloads!

I believe this is baked into Retroarch itself since the beginning, it appeared as a downloadable core for some time but it hadn’t any real use as far as I can tell, you don’t need an external DLL for it, just load the video directly into the executable and you’re good.
