He's legit.

That reminds me of a thing that you mentioned to me about fate testing and like the insanely rigorous process that's used to test everything that's incorporated into into FFmpeg.

Can you take me through the testing process?

I'm looking at a page, fate.ffmpeg.org, 81 minutes ago, 76 minutes ago, looking at the different architectures, the operating systems, different compilers, Apple, Clang version.

Visual Studio, Intel Compiler, Apple Clang, you name it.

What are some of the pain points?

Like maybe do you have...

You got to tell me about this lost art or the carriers of the flame of assembly.

What is assembly?

Why is it beautiful?

Why is it challenging?

How does it work?

You are a person who sees the beauty in assembly, but it's also extremely useful for these kinds of applications to actually significantly outperform, even see, which is crazy.

So for people who don't know, we've been talking about H.264.

AV1 is another hugely popular standard and codec that is increasingly taking over the internet.

Handwritten assembly, 240,000 lines.

That's incredible.

I mean, some of the stuff we're talking about is probably the biggest assembly code bases.

That's David, look at that.

Yeah, so this is another spicy tweet from you.
