When using WZGLBroadcaster, how should I set the image quality of the video to be delivered?

https://github.com/WowzaMediaSystems/gocoder-sdk-camera2-shaders/blob/master/gocoder-sdk-shaders/src/main/java/com/wowza/gocoder/sdk/shaders/example/gl/StreamingRenderer.java#L110

I am implementing implementation with reference to the above sample.

https://www.wowza.com/docs/how-to-configure-a-broadcast-with-gocoder-sdk-for-android

I’d like to use the above preset values, but how do I implement it to set the image quality of the delivery image?

In the sample comment, it is written that the frame size of broadcast and video source are the same, but I do not understand the part here.

Thank you for your answer.

The above problem seems to be solved.
However, crash occurred during delivery, I do not know the cause.
Although it seems that delivery video is processed by OpenGL, it seems that it is heavily loaded, but since the sample was crashing in the same way, there seems to be another cause.
If there is any information, it would be greatly appreciated if you could share it.

It seems that (a) is a thread used in onFrameAvailable of WZGLBroadcaster.

Can you slove the problem? Your device camera is support the camera 2 api?

It was solved.
It seems that the load on the UIThread caused by another processing was caused.

Thank you for reply.
