Fuzzing is good, robust sandboxing is better, I'd argue. There's just a much smaller surface area to cover for the latter.

I'm not aware of quantitative studies, but just from a design perspective, the surface that a WASM runtime presents seems intrinsically easier to defend than that of, say, the full Unix userspace that ffmpeg instances usually run in.
Anecdotally, many high-profile iOS and Android vulnerabilities originated in some more or less obscure codec implementation.
