my code is:

videoCapture = VideoCapture.Builder()//录像用例配置
                    .setTargetResolution(Size(640, 480))
                    .setVideoFrameRate(25)
                    .setBitRate(1 * 1024 * 1024)
                    .build()

startRecording code:

val outputFileOptions = VideoCapture
                .OutputFileOptions
                .Builder(File(path))
                .build()
            videoCapture?.startRecording(outputFileOptions,
                cameraExecutor,
                object : VideoCapture.OnVideoSavedCallback {
                    override fun onVideoSaved(outputFileResults: VideoCapture.OutputFileResults) {
                        onSuccess?.invoke(outputFileResults.savedUri)
                    }

                    override fun onError(
                        videoCaptureError: Int,
                        message: String,
                        cause: Throwable?
                    ) {
                        KLog.e(
                            TAG,
                            "startTakeVideo error,code = $videoCaptureError,message = $message"
                        )
                        runOnUIThread {
                            onError?.invoke(message)
                        }
                    }
                }
            )

in OnVideoSavedCallback onError info is:

startTakeVideo error,code = 1,message = Unexpected change in video encoding format.

how can I fix it please
