I am following these instructions regarding capturing and converting video from a Wear OS device, and I am running into problems. I get a video and I can tell it is my screen but it seems to be warped. This should be a green check with some white text.
There is a lot of noise when I run this:
ffmpeg -f rawvideo -vcodec rawvideo -s 400x400 -pix_fmt rgb24 -r 10 -i video.raw -an -c:v libx264 -pix_fmt yuv420p video.mp4
