Configure video tool in the toolbar

To include the video tool in the Rich Text Editor, you can add the toolbar item Video to the toolbarSettings items property.

To configure Video toolbar item, refer to the below code.

<ejs-richtexteditor id="editor">
    <e-richtexteditor-toolbarsettings items="@ViewBag.items"></e-richtexteditor-toolbarsettings>
</ejs-richtexteditor>
public class HomeController : Controller
{

    public ActionResult Index()
    {
        ViewBag.items = new[] { "Video" };
        return View();
    }
}

Insert video from web

To insert a video from the hosted link or local machine, you should enable the video tool on the editor’s toolbar. By default, the video tool opens the dialog, allowing you to insert a video as an embedded URL. You can switch to a web URL to insert the video file from the online source.

Insert from web URL

The video tool default opens the video dialog, allowing you to insert an embedded URL.

Rich Text Editor Embed URL Video insert

Rich Text Editor Video insert

Upload and insert video

In the video dialog, by using the browse option, select the video from the local machine and insert it into the Rich Text Editor content.

If the path field is not specified in the insertVideoSettings, the video will be converted into Blob url or Base64 and inserted inside the Rich Text Editor.

Restrict video upload based on size

Using the Rich Text Editor fileUploading event, you can restrict the video to upload when the given video size is greater than the allowed fileSize. Also, the video size in the argument will be returned in bytes.

NOTE

The file size in the argument will be returned in bytes.

In the following example, the video size has been validated before uploading and determined whether the video has been uploaded or not

}

Server-side action

The selected video can be uploaded to the required destination using the controller action below. Map this method name in insertVideoSettings.saveUrl and provide required destination path through insertVideoSettings.path properties.

NOTE

If you want to insert lower-sized video files in the editor and don’t want a specific physical location for saving the video, you can save the format as Base64.

In the following code blocks, you can insert the video files which are saved in the specified path.

Video save format

The video files can be saved as Blob or Base64 url by using the insertVideoSettings.saveFormat property, which is of enum type and the generated url will be set to the src attribute of the <source> tag.

NOTE

The default saveFormat property is set to Blob format.

By default, the files are saved in the Blob format.

<video>
    <source src="blob:http://ej2.syncfusion.com/3ab56a6e-ec0d-490f-85a5-f0aeb0ad8879" type="video/mp4" >
</video>

<video>
    <source src="data:video/mp4;base64,iVBORw0KGgoAAAANSUhEUgAAADAAAAAwCAYAAABXAvmHA" type="video/mp4" >
</video>

Replacing video

Once a video file has been inserted, you can replace it using the Rich Text Editor quickToolbarSettings videoReplace option. You can replace the video file either by using the embedded URL or the web URL and the browse option in the video dialog.

Delete video

To remove a video from the Rich Text Editor content, select the video and click the videoRemove tool from the quick toolbar. It will delete the video from the Rich Text Editor content as well as from the service location if the insertVideoSettings.removeUrl is given.

Once you select the video from the local machine, the URL for the video will be generated. You can remove the video from the service location by clicking the cross icon.

Rich Text Editor Video delete

The following example explains how to configure insertVideoSettings.removeUrl to remove a saved video from the remote service location when the following video remove actions are performed:

  • delete key action.
  • backspace key action.
  • Removing uploaded video file from the insert video dialog.
  • Deleting video using the quick toolbar videoRemove option.

Resize video

The Rich Text Editor has built-in video resizing support, which is enabled for the video elements added. The resize points will appear on each corner of the video when focusing so users can easily resize the video using mouse points or thumb through the resize points. Also, the resize calculation will be done based on the aspect ratio.

You can disable the resize action by configuring false for the insertVideoSettings.resize property.

NOTE

If the MinWidth and MinHeight properties are configured the video resizing does not shrink below the specified values.

Rename video before inserting

By using the insertVideoSettings property, you can specify the server handler to upload the selected video. Then by binding the fileUploadSuccess event, you can receive the modified file name from the server and update it in the Rich Text Editor’s insert video dialog.

Refer rename.cs controller file for configure the server-side.

Upload video with authentication

The Rich Text Editor control allows you to add additional data with the File Upload, which can be received on the server side. By using the fileUploading event and its customFormData argument, you can pass parameters to the controller action. On the server side, you can fetch the custom headers by accessing the form collection from the current request, which retrieves the values sent using the POST method.

NOTE

By default, it doesn’t support the UseDefaultCredentials property, you can manually append the default credentials with the upload request.

By default it doesn’t support UseDefaultCredentials property, we need to manually append the default credentials with the upload request.
