Configure the video tool in the toolbar

You can add the video tool in the Rich Text Editor toolbar using the toolbarSettings items property.

Rich Text Editor features are segregated into individual feature-wise modules. In this demo, we have used the following injectable services ToolbarService, LinkService, HtmlEditorService, VideoService in the @NgModule.providers section.

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

import { Component } from '@angular/core';
import { ToolbarService, QuickToolbarService, LinkService, HtmlEditorService, VideoService } from '@syncfusion/ej2-angular-richtexteditor';

Insert a video from the web

You can insert a video from either the hosted link or the local machine by clicking the video button in the editor’s toolbar. On Clicking the Video button, a dialog opens which allows you to insert video from the Embedded URL or web URL.

Insert from embed URL

The insert video dialog opens with the Embed URL option as default which allows you to insert an embedded URL.

Angular Rich Text Editor Embed URL Video insert

Insert from web URL

You can switch to Web URL by selecting the web URL check box. Inserting with the web URL option will add the video URL as the src attribute of the <source> tag.

Angular Rich Text Editor Video insert

Insert video from local machine

You can use the browse option on the video dialog, to 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 the Blob URL or Base64 and inserted inside the Rich Text Editor.

Restrict video upload based on size

You can restrict the video uploaded from the local machine when the uploaded video file size is greater than the allowed size by using the fileUploading event.

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.

import { Component } from '@angular/core';
import { ToolbarService, QuickToolbarService, LinkService, HtmlEditorService, VideoService } from '@syncfusion/ej2-angular-richtexteditor';
import { UploadingEventArgs } from '@syncfusion/ej2-angular-inputs';

@Component( {
    selector: 'app-root',
    template: `<ejs-richtexteditor id='' [toolbarSettings]='toolbarSettings' [insertVideoSettings] = 'insertVideoSettings' (fileUploading) = 'onVideoUpload($event)' >
    </ejs-richtexteditor>`,
    providers: [
        ToolbarService, QuickToolbarService, LinkService, VideoService, HtmlEditorService,
    ],
} )

export class AppComponent {
    public toolbarSettings: object = {
        items: [ 'Video' ]
    };
    public insertVideoSettings: Object = {
        saveUrl: 'https://aspnetmvc.syncfusion.com/services/api/uploadbox/Save',
        path: '../Files/'
    };
    public onVideoUpload = ( args: UploadingEventArgs ) => {
        let sizeInBytes: number = args.fileData.size;
        let fileSize: number = 500000;
        if ( fileSize < sizeInBytes ) {
            args.cancel = true;
        }
    }
}

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 the required destination path through insertVideoSettings.path properties.

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, the video module has been injected and can insert the video files saved in the specified path.

import { Component } from '@angular/core';
import { ToolbarService, QuickToolbarService, LinkService, HtmlEditorService, VideoService } from '@syncfusion/ej2-angular-richtexteditor';

        {
            return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });
        }
    }
}

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.

The default saveFormat property is set to 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 button 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.

Dimension

Set the default width, minWidth, height, and minHeight of the video element, when it is inserted in the Rich Text Editor using the width, minWidth, height, minHeight properties.

Through the quickToolbarSettings, also you can change the width and height using  the Change Size button. Once you click on the button, the video size dialog will open as below. In that, specify the width and height of the video in pixels.

Angular Rich Text Editor Video dimension

Display position

Sets the default display property for the video when it is inserted in the Rich Text Editor using the insertVideoSettings.layoutOption property. It has two possible options: Inline and Break. When updating the display positions, it updates the video elements’ layout position.

The default layoutOption property is set to Inline.

import { Component } from '@angular/core';
import { ToolbarService, QuickToolbarService, LinkService, HtmlEditorService, VideoService } from '@syncfusion/ej2-angular-richtexteditor';

@Component( {
    selector: 'app-root',
    template: `<ejs-richtexteditor id='' [toolbarSettings]='toolbarSettings' [insertVideoSettings] = 'insertVideoSettings'>
    </ejs-richtexteditor>`,
    providers: [
        ToolbarService, QuickToolbarService, LinkService, VideoService, HtmlEditorService,
    ],
} )
export class AppComponent {
    public toolbarSettings: object = {
        items: [ 'Video' ]
    };
    public insertVideoSettings: Object = {
      layoutOption: 'Break'
    };
}

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.

If the minWidth and minHeight properties are configured, the video resizing does not shrink below the specified values.

Rename video before inserting

You can use the insertVideoSettings property, to 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.

<ejs-richtexteditor id='' [toolbarSettings]='toolbarSettings' [insertVideoSettings] = 'insertVideoSettings' (fileUploadSuccess) = 'onVideoUploadSuccess($event)' >
<ng-template #valueTemplate>
   <p>The Rich Text Editor is WYSIWYG ("what you see is what you get") editor useful to create and edit content, and return the valid <a href="https://ej2.syncfusion.com/home/" target="_blank">HTML markup</a> or <a href="https://ej2.syncfusion.com/home/" target="_blank">markdown</a> of the content</p>
</ng-template>
</ejs-richtexteditor>
import { Component } from '@angular/core';
import { ToolbarService, QuickToolbarService, LinkService, HtmlEditorService, VideoService,} from '@syncfusion/ej2-angular-richtexteditor';

@Component({
  selector: 'app-root',
  templateUrl: `app.component.html`,
  providers: [ ToolbarService, QuickToolbarService, LinkService, VideoService, HtmlEditorService ],
})
export class AppComponent {
    public toolbarSettings: object = {
        items: ['Video'],
    };
    public insertVideoSettings: Object = {
        saveUrl: "[SERVICE_HOSTED_PATH]/api/uploadbox/Rename",
        path: "[SERVICE_HOSTED_PATH]/Files/"
    };
    public onVideoUploadSuccess = (args: any) => {
            alert("Get the new file name here");
            if( args.e.currenTarget.getResponseHeader('name') != null ){
                args.file.name = args.e.currentTarget.getResponseHeader('name');
                let fileName : any = document.querySelector(".e-file-name")[0];
                fileName.innerHTML = args.fileData.name.replace(document.querySelectorAll(".e-file-type")[0].innerHTML , '');
                fileName.title = args.fileData.name;
            }
    };
}

To configure server-side handler, refer to the below code.

int x = 0;
string file;
[AcceptVerbs("Post")]
public void Rename()
{
    try
    {
        var httpPostedFile = System.Web.HttpContext.Current.Request.Files["UploadFiles"];
        fileName = httpPostedFile.FileName;
        if (httpPostedFile != null)
        {
            var fileSave = System.Web.HttpContext.Current.Server.MapPath("~/Files");
            if (!Directory.Exists(fileSave))
            {
                Directory.CreateDirectory(fileSave);
            }
            var fileName = Path.GetFileName(httpPostedFile.FileName);
            var fileSavePath = Path.Combine(fileSave, fileName);
            while (System.IO.File.Exists(fileSavePath))
            {
                fileName = "rteFiles" + x + "-" + fileName;
                fileSavePath = Path.Combine(fileSave, fileName);
                x++;
            }
            if (!System.IO.File.Exists(fileSavePath))
            {
                httpPostedFile.SaveAs(fileSavePath);
                HttpResponse Response = System.Web.HttpContext.Current.Response;
                Response.Clear();
                Response.Headers.Add("name", fileName);
                Response.ContentType = "application/json; charset=utf-8";
                Response.StatusDescription = "File uploaded succesfully";
                Response.End();
            }
        }
    }
    catch (Exception e)
    {
        HttpResponse Response = System.Web.HttpContext.Current.Response;
        Response.Clear();
        Response.ContentType = "application/json; charset=utf-8";
        Response.StatusCode = 204;
        Response.Status = "204 No Content";
        Response.StatusDescription = e.Message;
        Response.End();
    }
}

Upload video with authentication

You can add additional data with the video uploaded from the Rich Text Editor on the client side, which can even 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.

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

import { Component } from '@angular/core';
import { ToolbarService, QuickToolbarService, LinkService, HtmlEditorService, VideoService,} from '@syncfusion/ej2-angular-richtexteditor';
import { UploadingEventArgs } from '@syncfusion/ej2-angular-inputs';

@Component({
  selector: 'app-root',
  template: `<ejs-richtexteditor id='' [toolbarSettings]='toolbarSettings' [insertVideoSettings] = 'insertVideoSettings' (fileUploading) = 'onVideoUpload($event)' >
    </ejs-richtexteditor>`,
  providers: [ ToolbarService, QuickToolbarService, LinkService, VideoService, HtmlEditorService ],
})
export class AppComponent {
  public toolbarSettings: object = {

  };
  public insertVideoSettings: Object = {
    saveUrl: "[SERVICE_HOSTED_PATH]/api/uploadbox/SaveFiles",
    path: "[SERVICE_HOSTED_PATH]/Files/"
  };
  public onVideoUpload = (args: UploadingEventArgs) => {
    let accessToken = "Authorization_token";
    // adding custom form Data
    args.customFormData = [ { 'Authorization': accessToken}];
  };
}
public void SaveFiles(IList<IFormFile> UploadFiles)
{
    string currentPath = Request.Form["Authorization"].ToString();
}
