The people who write DSLs for video codec asm, or who claim that it's fine to use intrinsics or X higher-level language and it will still be fast enough to be usable, are simply wrong and have never been able to demonstrate otherwise. Having said that I do think you could write a DSL to generate safe performant asm for a video codec. Just not a platform-independent one. It would still have to be asm.

It sounds like your second statement contradicts your first. But also, WUFFS exists and it looks like the Google Chrome GIF decoder ships in it: https://github.com/google/wuffs https://github.com/google/wuffs

  It does not contradict it, and also, a gif is not a video.

    > a gif is not a video. They're not that different; the image codec WebP is derived from VP8's intra-frame coding.

      I'm well aware and I know the inventor. The important difference for performance is that a gif isn't 60fps.
