我用gstreamer拍照，也出现报错，我安装的是官方的FIREFLY-RK3288-UBUNTU18.04-GPT-20191205-1903

我是用这个命令，用OV13850摄像头模块拍照，拍的照片是花的，改成USB摄像头（device=/dev/video5）拍的照片是正常的，请问是不是摄像头模块有问题

照片分别是两个摄像头拍的效果

使用OV13850摄像头模块拍照，还会出现这个错误日志rkisp1: CIF_ISP_PIC_SIZE_ERROR (0x00000001)rkisp1: CIF_ISP_PIC_SIZE_ERROR (0x00000001)

应该不是模块的问题。在/usr/local/bin下有脚本dual-camera-rkisp.sh，是用gstreamer来预览摄像头的，你看看可不可参照。
