onPreviewFrame is not called

You should implement StreamingPreviewCallback and invoke mCameraStreamingManager.setStreamingPreviewCallback(your implemented class);

byte[] is not encoded data, just YUV data.

I implemented SurfacePreviewCallback in main activity

public class BroadcastActivity extends ImmersiveActivity implements CameraStreamingManager.StreamingStateListener, StreamingPreviewCallback

@OverRide
public void onPreviewFrame(byte[] bytes, Camera _camera)
{
camera = _camera;
}

and later in code I do this

mCameraStreamingManager.setStreamingPreviewCallback(this);

but the onPreviewFrame is not called.

Just found that the onPreviewFrame is called only when I am using SW_VIDEO_WITH_SW_AUDIO_CODEC. Its not working with HW_VIDEO_WITH_HW_AUDIO_CODEC

Is it by design?

[jpxiong]

Yep.

Will it change in near future?

Even we cannot add filters if the onDrawFrame() callback is not called for HW_VIDEO_WITH_HW_AUDIO_CODEC
