Args:
request (:class:`google.ads.googleads.v4.services.types.GetMediaFileRequest`):
The request object. Request message for
[MediaFileService.GetMediaFile][google.ads.googleads.v4.services.MediaFileService.GetMediaFile]
resource_name (:class:`str`):
Required. The resource name of the
media file to fetch.
This corresponds to the ``resource_name`` field
on the ``request`` instance; if ``request`` is provided, this
should not be set.
retry (google.api_core.retry.Retry): Designation of what errors, if any,
should be retried.
timeout (float): The timeout for this request.
metadata (Sequence[Tuple[str, str]]): Strings which should be
sent along with the request as metadata.
Returns:
google.ads.googleads.v4.resources.types.MediaFile:
A media file.
