转屏功能开发

场景介绍

实现客户端横竖屏切换。

前提条件

视频流引擎启动成功。

开发流程

在orientationCallback回调函数，处理转屏功能。

编码实例

public void onVmiEngineEvent (int event, int reserved0, int reserved1, int reserved2, int reserved3, String additionInfo) {
    if (event == VideoEngine.VMI_ENGINE_EVENT_ORIENTATION_CHANGED) {
        engineOrientation = reserved0;
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
               setRotation(engineOrientation);
            }
         });
    }
}

private void setRotation(int rotation) {
        final int rota = rotation;
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                if (oritentation != rota) {
                    oritentation = rota;
                    switch (oritentation) {
                        case Surface.ROTATION_0:
                            // surfaceView  ui旋转
                            surfaceView.setScreenRotation(VideoEngine.Rotation.ROTATION0);
                            // 设置屏幕的方向
                            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
                            break;
                        case Surface.ROTATION_90:
                            surfaceView.setScreenRotation(VideoEngine.Rotation.ROTATION90);
                            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

                            break;
                        case Surface.ROTATION_180:

                            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT);
                            break;
                        case Surface.ROTATION_270:
                            surfaceView.setScreenRotation(VideoEngine.Rotation.ROTATION270);
                            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE);
                            break;
                        default:
                            break;
                    }
                }
            }
        });
