110 | Developer’s Guide EPiServer Community 3.1 ... File: Name: Description: Adding a video is done via the VideoGalleryHandler.AddVideo(Video) method. In the codebehind below we show how it’s called when the UploadButton.Click event is fired. Import Necessary Namespaces First import the necessary namespaces that will be used to manage video galleries. The namespaces StarCommunity.Modules.VideoGallery, StarCommunity.Core, StarCommunity.Core.Modules and StarCommunity.Core.Modules.Security are described by clicking on their names. Make sure you add the assemblies as a reference, mentioned in Setting up Visual Studio. using StarCommunity.Core; using StarCommunity.Core.Modules; using StarCommunity.Core.Modules.Security; using StarCommunity.Modules.VideoGallery; © EPiServer AB
Tutorials | 111 Calling AddVideo protected void UploadButton_Click(object sender, EventArgs e) { VideoGallery vg = VideoGalleryHandler.GetVideoGallery(1234); IAuthor author = null; if (StarCommunitySystem.CurrentContext.DefaultSecurity. CurrentUser != null) author = new UserAuthor((IUser)StarCommunitySystem.CurrentContext. DefaultSecurity.CurrentUser); else author = new GuestAuthor("Guest"); } Video video = new Video(this.textBoxName.Text, this.textBoxDescription.Text, vg, PublishState.Published, author); video = VideoGalleryHandler.AddVideo(v); The video variable now contains the video committed to the database with its unique ID set. Note that the UploadButton_Click method will not be called when the user clicks the button in the webbrowser, it is actually called by the CDN-provider when it gets the Received-notification from the CDN, as shown in the above process flow chart, this will happen within a minute or so after the video file has been completely uploaded. If the page throws an exception when the CDN-provider “clicks” the button, it will be shown in the server’s Application EventLog. The CDN-provider will retry this 3 more times until it gives up and the video will be erased from the CDN’s queue and storage. During this time, and if everything was successful in previous steps, the CDN has probably begun transcoding the video file, when this is done the video’s ProcessingStage will be set to ProcessingStage.Completed and it can now be displayed in a webpage or in the administration interface. 2.27.3 Remove video Removing a video is done by calling VideoGalleryHandler.RemoveVideo(Video). The video will be removed locally from EPiServer Community and at the CDN’s storage. using StarCommunity.Modules.VideoGallery; ... Video video = VideoGalleryHandler.GetVideo( 1234 ); VideoGalleryHandler.RemoveVideo(video); 2.27.4 Update video Updating a video is done by calling VideoGalleryHandler.UpdateVideo(Video). Since the cache is read-only, we need to clone objects before we update them so that the changes are not visible before they are committed to the database. © EPiServer AB
