      @张志伟 yavta 我们wiki上有代码链接的。其实就是标准v4l2 buffer的方式。你可以参考一下yavta代码。

                用7.5.3.2中的命令是可以取图的

                      @张志伟 我意思是你先严格按照7.4.4.2的命令试试，用Y8，而不是Y16

                        用Y8替代Y16也不行，然后调用设备，出现如下信息

                        目前调用图像都是通过gstreamer这个方法调用的，我们软件工程师怀疑你们的驱动是不是不完善，或者我们用的驱动不完善。或者说你们的驱动不适用于MV-MIPI-IMX265M这个摄像头？

                          @张志伟 按照我我们wiki上步骤去调用yavta存图一定是可以的。你把你用的命令发出来我看看。
