VivoX21 UDA 机型录像执行mediaRecorder.start()崩溃

Question

使用Camera+MediaReocrd实现相机录制小视频功能

在 VivoX21 UDA 机型上录像执行

mediaRecorder.start()

时**崩溃**

相同的代码, 暂时测试其他机型可以正常录制,没发现问题;

下面是部分点击按钮录像代码:

        if (mediaRecorder == null) {
            mediaRecorder = new MediaRecorder();
        }
        if (mParams == null) {
            mParams = mCamera.getParameters();
        }
        List<String> focusModes = mParams.getSupportedFocusModes();
        if (focusModes.contains(Camera.Parameters.FOCUS_MODE_CONTINUOUS_VIDEO)) {
            mParams.setFocusMode(Camera.Parameters.FOCUS_MODE_CONTINUOUS_VIDEO);
        }
        mCamera.setParameters(mParams);
        mCamera.unlock();
        mediaRecorder.reset();
        mediaRecorder.setCamera(mCamera);
        if (needVoice) {
            mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);

        } else {
            videoSize = CameraParamUtil.getInstance().getPreviewSize(mParams.getSupportedVideoSizes(), 400,
                    screenProp);
        }
        if (videoSize.width == videoSize.height) {
            mediaRecorder.setVideoSize(preview_width, preview_height);
        } else {
            //_这里vivoX21 uda 匹配的videoSize  864*480_
            mediaRecorder.setVideoSize(videoSize.width, videoSize.height);
        }
        if (SELECTED_CAMERA == CAMERA_FRONT_POSITION) {
            //手机预览处理
            if (cameraAngle == 270) {
                //横屏
                if (nowAngle == 0) {
                    mediaRecorder.setOrientationHint(180);
                } else if (nowAngle == 270) {

            }
        } else {

        }

        mediaRecorder.setVideoEncodingBitRate(mediaQuality);
        mediaRecorder.setPreviewDisplay(surface);

        videoFileName = "video_" + System.currentTimeMillis() + ".mp4";
