Jupyterでffmpegを使いたい

###実現したいこと・実行したこと
JyputerLabでbar_chart_raceを行いたいと思い以下のようなコード実行しました。
コードは以下の通りです、

import pandas as pd
import bar_chart_race as bcr

df = pd.read_csv('tennis.csv')

bcr.bar_chart_race(df)

tennis.csvの中身は以下のようになります

week_title	player_slug	ranking_points
0	2000/1/31	andre agassi	5045
1	2000/1/31	gustavo kuerten	2169
2	2000/1/31	magnus norman	2083
3	2000/1/31	marcelo rios	1846
4	2000/1/31	nicolas kiefer	2325

###エラー
実行したら次のようなエラーが発生しました。

###試したこと
https://www.gyan.dev/ffmpeg/builds/
からreleaseにあるhttps://www.gyan.dev/ffmpeg/builds/ffmpeg-release-full.7zを
ダウンロードし、解凍したものをProgram Filesに置きました。その後、システム環境変数の
PathにC:\Program Files\ffmpeg-4.3.2-2021-02-20-full_build\binを通したのですが上記のエラーが変わらず発生します。
