Hello I am testing Camera2Video source code and found error as below

```
2020-11-04 14:55:39.317 30311-3794/com.android.example.camera2.video E/MediaRecorder: stop failed: -1007

```

However when i change camera device session request configuration like below, error does not occur anymore. I am wondering there is any problem with `set(CaptureRequest.CONTROL_AE_TARGET_FPS_RANGE, Range(args.fps, args.fps))`.

```

This is my device specification

- model number: SM-N971N
