Usage

Download

 implementation 'me.jessyan:camerafilters:1.0'

Declare permissions:

 <uses-permission android:name="android.permission.CAMERA"/>

Declare feature:

 <uses-feature 
        android:glEsVersion="0x00020000"
        android:required="true"/>

Step 1

 mFilterManager = FilterManager
                .builder() 
                .context(mApplicationContext)
                .isUseQiniu(false)//是否在 qiniu 云直播上使用滤镜
                .addExtFilterListener(new onExtFilterListener() {//添加扩展的滤镜,因为滤镜创建必须在 render 的回调中,所以统一在这里管理滤镜
                    @Override
                    public IFilter onCreateExtFilter(Context context, int index) {
                        switch (index) {
                            case 0://继承于 cameraFitlter 后可自定义 filter,此 Filter 可任意添加一张图片到界面上
                                return new CameraFilterBlend(context, R.mipmap.
                                        pic_addpic);
                            default:
                                return new CameraFilter(context, false);
                        }
                    }
                })
                .defaultFilter(new FilterInfo(false, 0))//设置默认滤镜(false 为使用内置滤镜,角标范围是 0-13,0 为透明滤镜)
                .build();

Step 2

• 在GLSurfaceView.Renderer的三个回调方法中，将参数传给FilterManager对应的方法.
• onSurfaceCreated ---> FilterManager.initialize();
• onSurfaceChanged ---> FilterManager.updateSurfaceSize(width, height);
• onDrawFrame ---> mFilterManager.drawFrame(mTextureId, mSTMatrix, mIncomingWidth, mIncomingHeight);
• 以上为GLSurfaceView.Renderer回调和FilterManager方法的对应关系（请参照 Demo）
• 最后在结束时记得调用mFilterManager.release()释放资源

Step 3 ( if you use qiniu see here )

 mCameraStreamingManager.setSurfaceTextureCallback(new SurfaceTextureCallback() {
            @Override
            public void onSurfaceCreated() {
               mFilterManager.initialize();
            }

            @Override
            public void onSurfaceChanged(int i, int i1) {
               mFilterManager.updateSurfaceSize(i, i1);
            }

            @Override
            public void onSurfaceDestroyed() {
                mFilterManager.release();
            }

            @Override
            public int onDrawFrame(int i, int i1, int i2, float[] floats) {
               return mFilterManager.drawFrame(var1, null, var2, var3);
            }
        });

• 在七牛直播上使用滤镜也非常简单,和第二步相似，记得FilterManager.isUseQiniu(true) & mFilterManager.drawFrame(var1, null, var2, var3);第二个参数一定要传 null,七牛视频编码必须为硬编码

FilterInfo structure

使用默认滤镜和切换滤镜需要传入 FilterInfo 对象

Field	Description
isExt	是否使用扩展的滤镜
index	滤镜在对应滤镜列表中的角标，如果 isExt 为 false，则使用内置滤镜列表，为 true 则对应扩展滤镜列表

Dev tips

具体用法参照Demo,有Opengl基础的可以自定义滤镜
