The algs for media codecs are typically in handwritten assembly in combination with C. Actual GPU hardware acceleration implements specific media algorithms in hardware and is not accessible from the browser. I'm not aware of any kind of gpu codec algs that work in browser.

They could use the WebCodec APIs to decode frames using the hardware, similar to how ffmpeg already supports VA-API for hardware decoding.
