我们买的摄像头模组，里面的camera sensor是镁光AR0130的。用我们之前的RK3066的板子获取视频没问题。

楼主的花屏是什么现象，是录像变成全绿色吗？

楼主在录像时切换一下录像的分辨率，看看其他分辨率录像会不会花屏。

支持的其他分辨率（640x480等）都试过了，都是花屏（图像横向交错，能大概看到视频轮廓）。
另外发现，我在用自带的程序Camera，拍照时，拍出来的是全绿色，再次点击拍照，系统就会崩溃重启！

好像是在jpeg硬解码时出的问题：

D/jpeghw(145): TB: jpeg API returned : JPEGDEC_STRM_ERROR

下面是摄像头输出的原始jpeg图像（从CameraHal获取frame后得到），麻烦工程师分析一下，是不是格式不对？还是jpeghw库兼容问题？

看来跟分辨率没关系，我觉得应该跟数据的frame format 像素格式有关。楼主可以试一下这里：
hardware/rk29/camera/CameraHal/CameraUSBAdapter.cpp

//define  the frame info ,such as w, h ,fmt
int CameraUSBAdapter::reprocessFrame(FramInfo_s* frame)
{
    int ret = 0;
    //  usb camera may do something
   	#if (IOMMU_ENABLED == 1)
    int phy_addr = mPreviewBufProvider->getBufShareFd(frame->frame_index);
    #else
    int phy_addr = mPreviewBufProvider->getBufPhyAddr(frame->frame_index);
    #endif
    if( frame->frame_fmt == V4L2_PIX_FMT_MJPEG){
    	   char *srcbuf = frame->vir_addr;
    	   if((srcbuf[0] == 0xff) && (srcbuf[1] == 0xd8) && (srcbuf[2] == 0xff)){
        //decoder to NV12
        VPU_FRAME outbuf;
        unsigned int output_len;
        unsigned int input_len;
        output_len = 0;
        input_len = frame->frame_size;

        ret = mMjpegDecoder.decode(mMjpegDecoder.decoder,
                                    (unsigned char*)&outbuf, &output_len,
    		                          (unsigned char*)frame->vir_addr, &input_len,
    		                          phy_addr);
        if (ret < 0){
            LOGE("%s(%d): mjpeg stream is error!",__FUNCTION__,__LINE__);
	        }
	    }else{
	    		LOGE("mjpeg data error!!");
	    		return -1;
        }
    }else if(frame->frame_fmt == V4L2_PIX_FMT_YUYV){

        ret = cameraFormatConvert(V4L2_PIX_FMT_YUYV, V4L2_PIX_FMT_NV12, NULL,
							 (char*)frame->vir_addr, (char*)mPreviewBufProvider->getBufVirAddr(frame->frame_index),
							 0,0,frame->frame_size,
							 frame->frame_width, frame->frame_height, frame->frame_width,
							 frame->frame_width, frame->frame_height, frame->frame_width,
							 false);
        if (ret < 0){
            LOGE("%s(%d): yuyv convert to nv12 error!",__FUNCTION__,__LINE__);
        }

    }else{
        LOGE("camerahal not support this format %d",frame->frame_fmt);
        ret =  -1;
    }

    frame->frame_fmt = V4L2_PIX_FMT_NV12;
    frame->phy_addr = phy_addr;
    frame->vir_addr = mPreviewBufProvider->getBufVirAddr(frame->frame_index);
    frame->zoom_value = mZoomVal;

	int w,h;
	w = frame->frame_width;
	h = frame->frame_height;
	if((w&0x0f) || (h&0x0f)){
		char *buf = malloc(w*h*3/2);
		if(buf != NULL){
			memcpy(buf,frame->vir_addr,w*h);
			memcpy(buf+w*h,frame->vir_addr+((w+15)&0xfff0)*((h+15)&0xfff0), w*h/2);
			memcpy(frame->vir_addr,buf,w*h*3/2);
			free(buf);
		}
	}

    //do zoom here?
    return ret;

}

这个函数里面好像要处理不同的像素格式的。

现在深度怀疑是VPU库硬解jpeg的兼容问题，麻烦版主能确认一下！

VPU库是系统中很重要的库，rk平台并不希望我们擅自修改而产生其他问题，所以rk平台并未对VPU库开源。建议楼主在传数据给VPU硬解前先适当处理一下数据。

我最后通过libjpeg把摄像头输出的格式转换成JFIF格式后，能正常显示视频了。但是效率不好。这不是解决问题的根本办法。
还是希望能改进VPU库！:Q
