Streaming and recording with different quality Camera2 API

See original GitHub issue

Hi! I need to stream and record with different video quality using Camera2 API. I read this issue (https://github.com/pedroSG94/rtmp-rtsp-stream-client-java/issues/228), but it is for Camera1. As i understand, i need to duplicate VideoEncoder in Camera2Base.java, add this new VideoEncoder to listSurfaces in Camera2ApiManager.java’s startPreview and set useOpengl to false in RtmpCamera2 init: rtmpCamera2 = new RtmpCamera2(App.getContext(), false, connectCheckerRtmp); Am i right? But after setting useOpengl to false (without any other modifications) i got errors: 2019-01-14 11:47:53.612 13103-13493/ru.altatec.server I/Camera2ApiManager: Camera opened 2019-01-14 11:47:53.613 13103-13493/ru.altatec.server E/Camera2ApiManager: Configuration failed Device is Sony Xperia XZ1 Compact Android 9 and camera working at background.

Yes, you are right. You need modify library code. You have an example posted above but maybe you need fix something. I’m not doing this implementation because you need create 2 videoencoders to do it and this result in worse performance and it is more difficult to maintain

@pedroSG94 I was trying the proposed examples, and streaming was breaking. Is there a way to achieve this with the openglview? Creating two encoders and so on.

I have an idea to copy the surface in the meantime, but needs too much modification on the current base code and it can be really slow that way.

No, because openglview only support 2 surfaces (preview and encoder). You need modify SurfaceManager to make it work and create a way to scale image correctly to both encoders.
