Framebuffer Capture (Alternative)
If direct framebuffer access were available on RG:
# Capture raw framebuffer
fbgrab /tmp/d3-screen.png
# Or use ffmpeg
effmpeg -y -f fbdev -i /dev/fb0 -frames:v 1 /tmp/d3-screen.png
# Capture video
ffmpeg -y -f fbdev -framerate 30 -i /dev/fb0 -t 5 /tmp/d3-screen.mp4
