Collaborate and review videos frame by frame. WebViewer video allows users to annotate video frames, comment on frames, collaborate and review videos.

Annotations will be tied to specific frames and will only be rendered, when the video is seeked to the specific frames. This guide will show you how to get started with a free trial.

The source code for this project is available in our Git repo.

Prerequisites

• Node.js and NPM

Initial setup

Clone the repo to a specific directory and then navigate to it:

# command line
git clone https://github.com/PDFTron/webviewer-video-sample.git video
cd video

How to run

1. Navigate to the video directory and isntall the required dependencies to run the samples by executing:

npm install

2. Next run the sample by executing:

npm start

3. Navigate to http://localhost:3000/ and you will see the sample WebViewer running with a video, similar to above.

How it works

HTML5 Videos can be loaded into WebViewer with use of the @pdftron/webviewer-video package.

Install

npm install @pdftron/webviewer-video

Below is a sample setup of the video package with webviewer.

initializeVideoViewer is called to give WebViewer the ability to handle the loading of video files. Afterwards, a video can be loaded with loadVideo. Lastly settings to customize the behavior of the controls can be passed in when calling initializeVideoViewer.

import WebViewer from '@pdftron/webviewer';
import { initializeVideoViewer, renderControlsToDOM } from '@pdftron/webviewer-video';

WebViewer({
    path: '/webviewer/lib',
    selectAnnotationOnCreation: true,
  },
  viewer.current,
).then(async instance => {
  // Extends WebViewer to allow loading HTML5 videos (.mp4, ogg, webm).
  const {
      loadVideo,
  } = await initializeVideoViewer(
      instance,
      '---- Insert commercial license key here after purchase ----',
  );
  // Load a video at a specific url. Can be a local or public link
  // If local it needs to be relative to lib/ui/index.html.
  // Or at the root. (eg '/video.mp4')
  const videoUrl = 'https://pdftron.s3.amazonaws.com/downloads/pl/video/video.mp4';
  loadVideo(videoUrl);

  instance.Core.docViewer.on('documentLoaded', () => {
    const customContainer =
        instance.UI.iframeWindow.document.querySelector('.custom-container');
    // Inject the video Controls into WebViewer
    // Needs to be called after the document is loaded
    renderControlsToDOM(instance, customContainer);
  });
});

Import and Exporting Annotations

Importing and exporting annotations works the exact same way as it does on WebViewer, with the video annotations having additional the properties start-time and end-time.

Server configuration

Make sure your server has byte-range requests enabled to allow video streaming.
