| Encodes several seconds of video and checks that the encoder adheres to the |
| specified bitrate. |
| |
| Each frame has a number of new gradient filled ellipses appearing on it. |
| We can control complexity of the video by changing the number of ellipses. |
| It's easier on encoders than pure white noise, but not as easy as some static or |
| a ffmpeg test input. |
