Since you have an AMD cpu/apu, one last resort that I can think of is to capture webcam with hardware acceleration.
Extracted from https://trac.ffmpeg.org/wiki/Hardware/VAAPI
Also, you need to verify what "-vaapi_device" is the correct one for your machine.
The wiki has much more information.
Capture a raw stream from a V4L2 camera device and encode it as H.264:
$ ffmpeg -vaapi_device /dev/dri/renderD128 -f v4l2 -video_size 1920x1080 -i /dev/video0 -vf 'format=nv12,hwupload' -c:v h264_vaapi output.mp4
