Comment 4 for bug 1719690

Launching chromedriver independently and attempting to connect to it as a remote WebDriver instance, we can see that it attempts to launch chromium-browser as such:

```
/usr/lib/chromium-browser/chromium-browser --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --load-extension=/tmp/.org.chromium.Chromium.89Gfz0/internal --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12850 --safebrowsing-disable-auto-update --test-type=webdriver --use-mock-keychain --user-data-dir=/tmp/.org.chromium.Chromium.SGNNaW data:,
```

Which returns the following error:

```
/usr/lib/chromium-browser/chromium-browser: error while loading shared libraries: libffmpeg.so: cannot open shared object file: No such file or directory
```
