### Method Details

`set(videoId, onBehalfOfContentOwner=None, x__xgafv=None, media_body=None, media_mime_type=None)`

    As this is not an insert in a strict sense (it supports uploading/setting
    of a thumbnail for multiple videos, which doesn't result in creation of a
    single resource), I use a custom verb here.

    Args:
      videoId: string, Returns the Thumbnail with the given video IDs for Stubby or Apiary. (required)
      onBehalfOfContentOwner: string, <strong>Note:</strong> This parameter is intended exclusively for YouTube
    content partners.<br><br>The
    <code><strong>onBehalfOfContentOwner</strong></code> parameter indicates
    that the
    request's authorization credentials identify a YouTube CMS user who is
    acting on behalf of the content owner specified in the parameter value.
    This parameter is intended for YouTube content partners that own and manage
    many different YouTube channels. It allows content owners to authenticate
    once and get access to all their video and channel data, without having to
    provide authentication credentials for each individual channel. The actual
    CMS account that the user authenticates with must be linked to the
    specified YouTube content owner.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format
      media_body: string, The filename of the media request body, or an instance of a MediaUpload object.
      media_mime_type: string, The MIME type of the media request body, or an instance of a MediaUpload object.

    Returns:
      An object of the form:
