Implement ZegoEffect

[furkanKotic]

I am trying to implement a beauty filter using ZegoEffect. I started with the DeepAR example but I couldn't figure out how to do it.
The methods that can be used to process frames in ZegoEffect are as follows:

Example I420 process code:

ZegoEffectsVideoFrameParam param = new ZegoEffectsVideoFrameParam();
param.setFormat(ZegoEffectsVideoFrameFormat.I420);
param.setWidth(width);
param.setHeight(height);
if (mZegoEffects != null) {
    mZegoEffects.processImageBufferYUV(data, dataLength, param);
}

How can I integrate it?

I think the only way is use the example code with textureId:
https://docs.zegocloud.com/article/9916#5

I'm not sure if this should works or not.
You can try copy this class:
https://github.com/pedroSG94/RootEncoder/blob/master/encoder/src/main/java/com/pedro/encoder/input/gl/render/filters/NoFilterRender.java
And add the code example inside draw method and replace the previousTextureId with the textureId result

Do I need to send the previousTexId parameter as mTextureId and assign the incoming zegoTextureId value to the previousTexId value?

[pedroSG94]

I'm not sure, test both cases. I think yes
Also, you can get width and height with getWidth() and getHeight() methods

Also, to improve the performance avoid instace the ZegoEffect inside draw method and do it inside initGlFilter or constructor

[furkanKotic]

ZegoEffect wants me to send textureId in a loop. For this reason, I think I need to use it in drawFilter. TextureId 0 comes in initGlFilter and ZegoEffect does not accept it.
No error occurs but I see a black screen.

Hello,

It is not working but I'm not sure about the reason
Can you create a project example and share me it to test?

Sure. I sent an invite. @pedroSG94
