- Windows/Mac: Use `--enable-widevine-cdm` command-line flag to enable download of CDM binaries via the component updater. - Linux: Use `--widevide-cdm-path` and `--widevine-cdm-version` command-line flags to load CDM binaries that already exist on the system. - A cache-path value is usually required when CDM is enabled.
