If I watch a video on the internet in the chrome browser, and the video is encoded with H265 or VP9 (or the future AV1), and I have a Nvidia GPU (GTX 1080): Is the video decoding happening on the GPU or the CPU? (I have hardware acceleration enabled in chrome)?

Yes, like the Hardware Acceleration's enabled in your Chrome as you wrote above.

When hardware acceleration is enabled in Chrome, the browser passes most of the graphical intensive tasks within the browser to the GPU, meaning it makes the most of your hardware.

Actually GPU acceleration is hardware-dependent and also old GPU drivers can cause problems. On GTX 1080 with recent drivers you have "complete acceleration of VP9 profile 2 (10-bit) and maximum resolution of up to 8192 x 8192 pixels (8k resolution) for all HEVC and VP9 profiles." For av1 decoding you have to rely on CPU solely as the Feature Set K of PureVideo is introduced with GTX 3080. (Source url)
