Android WebRTC自定义远程和本地视图

Question

我正在Android项目中实现webrtc,我基于github中的这个示例.

此示例使用libjingle库.这是创建视频渲染视图的方式:

        // Create video renderers.
        VideoRendererGui.setView((GLSurfaceView)videoView, new Runnable() {
            @Override
            public void run() {
                createPeerConnectionFactory();
            }
        });
        remoteRender = VideoRendererGui.create(
                REMOTE_X, REMOTE_Y,
                REMOTE_WIDTH, REMOTE_HEIGHT, scalingType, false);
        localRender = VideoRendererGui.create(
                LOCAL_X_CONNECTING, LOCAL_Y_CONNECTING,
                LOCAL_WIDTH_CONNECTING, LOCAL_HEIGHT_CONNECTING, scalingType, true);

我的问题是我如何设法自定义remoteRender和localRender,以便我可以position在GLSurfaceView它的宽度和高度更改它

编辑:

我做了一个听众,我试过这个:

    @Override
    public void onWidthHeightChange(int width, int height) {
        VideoRendererGui.update(remoteRender,
                REMOTE_X-width, REMOTE_X-height,
                REMOTE_WIDTH-width, REMOTE_HEIGHT-height, scalingType, false);
        if (iceConnected) {
            VideoRendererGui.update(localRender,
                    LOCAL_X_CONNECTED, LOCAL_Y_CONNECTED,
                    LOCAL_WIDTH_CONNECTED, LOCAL_HEIGHT_CONNECTED,
                    ScalingType.SCALE_ASPECT_FIT, true);
        } else {
            VideoRendererGui.update(localRender,
                    LOCAL_X_CONNECTING, LOCAL_Y_CONNECTING,
                    LOCAL_WIDTH_CONNECTING, LOCAL_HEIGHT_CONNECTING, scalingType, true);
        }
    }

当我为宽度和高度赋予值150时,它给出了这个错误:

            at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1239)

使用解决方案编辑2:

当我看到mattm答案时,我明白他是对的.

当我在搜索我的异常时,我发现它是从libjingle库中抛出的异常.我在第368,347行找到了这段代码VideoRendererGui.java我找到了解决方案.

添加视图高度和宽度时,它必须基于以下代码在这些范围内:

  /**
   * Creates VideoRenderer.Callbacks with top left corner at (x, y) and
   * resolution (width, height). All parameters are in percentage of
   * screen resolution.
   */
  public static YuvImageRenderer create(
      int x, int y, int width, int height) {
    // Check display region parameters.
    if (x < 0 || x > 100 || y < 0 || y > 100 ||
        width < 0 || width > 100 || height < 0 || height > 100 ||
        x + width > 100 || y + height > 100) {
      throw new RuntimeException("Incorrect window parameters.");
    }

因此,只要我按照这些规则调用该方法VideoRendererGui.update(...就可以完美地工作

谢谢

Answer 1

就像更改字段一样简单

• 坐标：
  REMOTE_X, REMOTE_Y, 或LOCAL_X_CONNECTING, LOCAL_Y_CONNECTING,
• 或尺寸： REMOTE_WIDTH、REMOTE_HEIGHT或LOCAL_WIDTH_CONNECTING、LOCAL_HEIGHT_CONNECTING

如果您想在创建对象后更改渲染，请调用VideoRendererGui.update(remoteRender, ...)。
