Android 版 WebRTC : VideoRendererGUI 在视频通话中截取屏幕截图 [英] WebRTC for Android : VideoRendererGUI take a screenshot in the video call

问题描述

需求是在视频通话中保存一个视频帧.我做了一个演示，通过 GLSurfaceView 的方法onDrawFrame"截取屏幕截图.但是当我使用webrtc时，它有自己的渲染器VideoRendererGUI".然后当我想覆盖它时，我发现它无法被覆盖.主要部分代码:

The demand is that saving a video frame in the video call. I have made a demo that take a screenshot through the GLSurfaceView's method "onDrawFrame". But when I use the webrtc, it have its own renderer "VideoRendererGUI" .And then when I want to override it, I find it can't be overrided. the main part code :

   vsv = (GLSurfaceView) findViewById(R.id.glviewchild_call);
    vsv.setPreserveEGLContextOnPause(true);
    vsv.setKeepScreenOn(true);

    VideoRendererGui.setView(vsv, new Runnable() {
        @Override
        public void run() {
            init();
        }
    });

如果你有其他截屏方式，也可以分享给我.非常感谢！

And If you have another way to take a screenshot, you can also share with me. Thanks a lot!

推荐答案

如果使用 SurfaceViewRenderer 来显示流，可以使用 这个答案 在通话中捕捉帧.

If you use a SurfaceViewRenderer to display the stream, you can use the solution in this answer to capture a frame on the call.

基本上，将 surfaceViewRenderer.AddFrameListener 与实现 EGLRenderer.FrameListener

Basically, using surfaceViewRenderer.AddFrameListener with a class that implements EGLRenderer.FrameListener
