TI中文支持网ov3640输出8位并行YUV数据。AM3715上运行的是TI提供的Android2.2.点击android自带的照相机应用，能够进行预览继而进行拍照，但是点击按钮切换到录像模式，液晶屏幕上立即显示花屏，无法预览了。ov3640输出的为1027*468分辨率的数据。
log输出信息如下，

补充一下我想实现的是录制352*288分辨率的3gp视频。

我在int CameraHardware::previewThread()这个线程里做了语句输出，发现当为record时和照相前的预览走的都是如下的if语句，可是拍照前的预览就好用，摄像前的预览就不好用。明明是是同一段代码啊。
if (mMsgEnabled & CAMERA_MSG_PREVIEW_FRAME) {/*convert fuction conver the data from YUV to rgb16*/ mCamera->convert((unsigned char *) rawFramePointer, (unsigned char *) mPreviewHeap->getBase(), PREVIEW_WIDTH, PREVIEW_HEIGHT);
yuyv422_to_yuv420sp((unsigned char *)rawFramePointer, (unsigned char *)mHeap->getBase(), PREVIEW_WIDTH, PREVIEW_HEIGHT); mDataCb(CAMERA_MSG_PREVIEW_FRAME, mBuffer, mCallbackCookie); }

看楼主是android应用,建议在e2e的android论坛上也提问一下.
