The code is trivial:
applicationOptions := []application.ApplicationOption{
application.WithDebug(true),
application.WithCacheDisabled(true),
}

client := application.NewApplication(applicationOptions...)
if err := client.Start(cThing.Config.CastIp, cThing.Config.Port); err != nil {
return err
}

defer client.Close(true)
url := fmt.Sprintf("%s/%s", cThing.Config.AssetsUrl, mediaFile)
startTime := 0
contentType := ""
transcode := false
detach := false
err = client.Load(url, startTime, contentType, transcode, detach, false)
if err != nil {
return err
}
