when start video

[alpertayfun]

I added surfaceview into layout and everything is perfect but I can not see video when start of activity. when I click to change camera way and call switchCamera(). Btw , I can see video front and then back.

This is bug or something ?

My code is :

`rtmpCamera1 = new RtmpCamera1(glView, connectCheckerRtmp); if (rtmpCamera1.prepareAudio() && rtmpCamera1.prepareVideo()) { rtmpCamera1.startStream(urlForLive); } else { Log.d("livestream","This device cant init encoders, this could be for 2 reasons: The encoder selected doesnt support any configuration setted or your device hasnt a H264 or AAC encoder (in this case you can see log error valid encoder not found)"); }

    rtmpCamera1.startPreview();`

Did you startPreview on surfacechanged method? https://github.com/pedroSG94/rtmp-rtsp-stream-client-java/blob/master/app/src/main/java/com/pedro/rtpstreamer/defaultexample/ExampleRtmpActivity.java#L191

No. Still is black when start of activity. I added same startPreview into surface surfaceCreated method. But still black. But when I click change camera way then I got video.

Phone is General Mobile GM8 Go Edition.

Is the demo app working?

Your error is because you are doing startStream onCreate but you can't open a preview because surface is not created yet (startStream and startRecord open a preview if you haven't one). In this case your startPreview is ignored because you are streaming. https://github.com/pedroSG94/rtmp-rtsp-stream-client-java/blob/master/rtplibrary/src/main/java/com/pedro/rtplibrary/base/Camera1Base.java#L302

If you want start stream when you open activity you should wait surfaceChanged before start stream, you can't do it in onCreate method. startPrview should be called if you want a preview before start stream(For example, open activity with preview and startStream when you click on a button like in my example).

I just added switchCamera in surfaceCreated method. And it is display right now but still not working on start of activity. How can I change camera way on start of rtmp stream ?

  @Override
    public void surfaceCreated(SurfaceHolder holder) {
        rtmpCamera1.startPreview();
        rtmpCamera1.switchCamera();
    }

Sorry. I see now your reply. Really thank you. :)

[pedroSG94]

If you want start with front camera use this surfaceChanged method:

  @Override
  public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) {
    rtmpCamera1.startPreview(CameraHelper.Facing.FRONT);
    if (rtmpCamera1.prepareAudio() && rtmpCamera1.prepareVideo()) {
      rtmpCamera1.startStream(urlForLive);
    } else {
      Log.d("goLive","This device cant init encoders, this could be for 2 reasons: The encoder selected doesnt support any configuration setted or your device hasnt a H264 or AAC encoder (in this case you can see log error valid encoder not found)");
    }
  }
