Android WebRTC configures remote and local view

Question

I am implementing webrtc in an Android project, and I'm based on this example on github .

This example uses the libjingle library. This creates a video rendering view:

// 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); 

My question is how can I configure remoteRender and localRender so that I can change its position in GLSurfaceView and its width and height

EDIT:

I made a listener and I tried this:

  @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); } } 

When I give a value of 150 both in width and in height, it gives me this error:

 08-21 14:34:01.621 7636-7636/org.appspot.apprtc E/AppRTCDemoActivity﹕ Fatal error: glUseProgram: GLES20 error: 1281 java.lang.RuntimeException: glUseProgram: GLES20 error: 1281 at org.webrtc.GlUtil.checkNoGLES2Error(GlUtil.java:48) at org.webrtc.GlShader.useProgram(GlShader.java:123) at org.webrtc.GlRectDrawer.drawOes(GlRectDrawer.java:132) at org.webrtc.VideoRendererGui$YuvImageRenderer.draw(VideoRendererGui.java:371) at org.webrtc.VideoRendererGui$YuvImageRenderer.access$800(VideoRendererGui.java:131) at org.webrtc.VideoRendererGui.onDrawFrame(VideoRendererGui.java:722) at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1522) at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1239) 

EDIT 2 with solution:

When I looked at the answer of mattm , I realized that he was right.

While I was looking for my exception, I found that this exception was selected from the libjingle library. I found this VideoRendererGui.java code snippet here on line 368, 347. I found a solution for my questions.

When adding the height and width of the view, it should be inside these ranges based on this code:

  /** * 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."); } 

So as long as I follow these rules, calling the VideoRendererGui.update(... method will work fine

thanks

Answer 1

It is as simple as changing fields

• coordinates:
  REMOTE_X , REMOTE_Y or LOCAL_X_CONNECTING , LOCAL_Y_CONNECTING ,
• or sizes: REMOTE_WIDTH , REMOTE_HEIGHT or LOCAL_WIDTH_CONNECTING , LOCAL_HEIGHT_CONNECTING

If you want to change the rendering after creating the objects, call VideoRendererGui.update(remoteRender, ...) .
