75前摄像头录像时上下拉伸

估计是尺寸没有设置成4:3

这个是怎么设置的?

getinfo的函数里可以设置的，你看看。

这个改上层改好了，Camera\src\com\android\camera\VideoCamera.java 里 readVideoPreferences 加上或打开以下段
        mVideoSizeManager.getVideoSize(mProfile, mParameters.getSupportedPreviewSizes(), mOrientationCompensation);
        
        //Mediatek compensate install orientation of sensor.
        int camOri = CameraHolder.instance().getCameraInfo()[mCameraId].orientation;
        if (camOri == 180 || camOri == 0) {
                int temp = mProfile.videoFrameWidth;
                mProfile.videoFrameWidth = mProfile.videoFrameHeight;
                mProfile.videoFrameHeight = temp;
                Log.d(TAG, "mProfile.videoFrameWidth: " + mProfile.videoFrameWidth + " mProfile.videoFrameHeight: " + mProfile.videoFrameHeight);
        }
               
        getDesiredPreviewSize();
        //Mediatek modify to meet lower frame sensor
        List<Integer> supportedFrameRates = mParameters.getSupportedPreviewFrameRates();
        if (！isSupported(mProfile.videoFrameRate, supportedFrameRates)) {
                int maxFrame = getMaxSupportedPreviewFrameRate(supportedFrameRates);
                mProfile.videoBitRate = (mProfile.videoBitRate * maxFrame) / mProfile.videoFrameRate;
                mProfile.videoFrameRate = maxFrame;
                        bitrateChanged = true;
        }
