That is _not_ true. There is no OpenMP support in LLVM, what they misleadingly list is an unofficial fork.
Also OpenMP tends to be too limited to work for anything but trivially parallelizable things and I doubt you'll find many of these remaining.
I don't mind you trying, and I at least do not mind having OpenMP-only optimisations in FFmpeg but I would be surprised if you got much out of that.
