UndefVarError: '_unsuported_append_encode_type' not defined #406

Hi there,

When trying to create a video and filling it with images I get an error "UndefVarError: '_unsuported_append_encode_type' not defined", not sure what to do with it. I managed to reproduce the error with the following code:

writer = VideoIO.open_video_out("video.mp4", Gray{N0f8}, (480, 640), framerate=30)

for i in 1:200
    noise = rand(Gray, 640, 480)
    write(writer, noise)
end

close_video_out!(writer)

I am using VideoIO v1.0.7

Obviously a bug, but you should be able to avoid it by setting the same image element type as in the constructor.

Thank you Ian, I was quite puzzled by this error. Your solution indeed avoids the issue.
