Implementing a basic Video Face Filter App

Preparation

  • ZEGOCLOUD developer account – Sign up
  • A device that can connect to the internet and play audio and video.
  • Some knowledge of web development.
  • Include the ZEGO Express SDK in your project. See Integration and Implementation for more information.

Implementation steps

Follow these steps to get started with ZEGOCLOUD to add face filters for videos:

  1. Call the createStream method to create and obtain your media streams.
  2. Call the setEffectsBeauty method to enable the face beautification feature.
  3. Use the ZegoEffectsBeautyParam class to specify the parameters for the desired effects, including smoothIntensitywhitenIntensityrosyIntensity, and sharpenIntensity.
  • smoothingIntensity: Skin-smoothing. Smooth the skin while preserving facial details like moles.
  • whitenIntensity: Improves skin tone. To whiten your face, increase the overall brightness.
  • rosyIntensity: blusher on the cheeks. Continue with the warm color processing on the entire image.
  • sharpenIntensity: When the image is a little blurry, you can sharpen it slightly to make it clearer.
  • These effects have a value range of [0, 100], with a default value of 50. The intensity of the effect increases as the value increases.

Note: To enable face beautification before stream publishing, call the startPublishingStream method after enabling the feature.

When you’re done using the face beautification feature, call the setEffectsBeauty method with a value of “false” to disable it. Alternatively, you can call the destroyStream method to disable the feature and destroy the streams.

Remember, the face beautification effects are bound to the MediaStream and will not be affected when you call the useVideoDevice or replaceTrack methods. Make sure to disable the feature when it is no longer needed to conserve resources. With these steps in mind, you’ll be able to easily add face beautification to your video streams using ZEGOCLOUD.

You can use the codes below as starting point for adding face filters for videos:

// Create a stream. zg is the instance object of the ZegoExpressEngine.
const localStream = await zg.createStream();
const enable = true;
// Enable the face beautification.
await zg.setEffectsBeauty(
    localStream,
    enable,
    {
        sharpenIntensity: 50, 
        whitenIntensity: 50, 
        rosyIntensity: 50,
        smoothIntensity: 50
    }
)

// Start the stream publishing.
zg.startPublishingStream("stream1", localStream);

// Disable the face beautification. 
await zg.setEffectsBeauty(localStream, false);

The code above does the following:

  1. Create a new media stream using the createStream method.
  2. Set the “enable” variable to “true” to turn on the face beautification feature.
  3. Use the setEffectsBeauty method to apply the desired effects, including sharpenIntensitywhitenIntensityrosyIntensity, and smoothIntensity. Set the intensity for each effect as desired.
  4. Start the stream publishing process by calling the startPublishingStream method and passing in the stream name and stream object.
  5. When you’re finished using the face beautification feature, disable it by calling the setEffectsBeauty method with a value of “false“.
  6. Remember, the “zg” variable in this code represents the instance object of the ZegoExpressEngine. Follow these steps to easily apply face beautification effects using ZEGOCLOUD.
