ImageIO and Python

[AVHWDeviceContext @ 0x1c91320] No VA display found for device: /dev/dri/renderD128.

import imageio

# All images must be of the same size
image1 = np.stack([imageio.imread('imageio:camera.png')] * 3, 2)
image2 = imageio.imread('imageio:astronaut.png')
image3 = imageio.imread('imageio:immunohistochemistry.png')

w = imageio.get_writer('my_video.mp4', format='FFMPEG', mode='I', fps=1,
                       codec='h264_vaapi',

w.append_data(image1)
w.append_data(image2)
w.append_data(image3)
w.close()

...

The top is the error. The source is listed and it is from imageio docs. online.

From what I can tell, the source is telling me, via the error, that ffmpeg does not encode for vaapi_device. Is this right?
