With the steps outlined above, cloning ffmpeg and compiling it, if you run `make -j$(nproc) fate-wmapro-2ch`, it should print one `TEST` line and exit with a 0 exit code if the code was correctly compiled, or print an error if it was misoptimized.

That is an entirely unrelated library for scaling and color conversion of video frames, it has nothing to do with the ARM SVE feature.
