V853的MPP无法在一个VIPP上使用两个vichn？

[likehengall]

*已经成功在vipp0上创建，virchn0和virchn1，打印如下

I0101 05:40:02.627953  1140 mpi_vi.c:1018]                  <AW_MPI_VI_CreateVirChn> we allow to create virChn[0] in disable status of vipp[0]

• 当我使 列表用AW_MPI_VI_EnableVirChn函数对virchn进行激活的时候出现如下情况
• 屏幕上只显示了第一张图片之后就卡住了，循环报错打印如下：

是的，需要两个VIPP或者分时复用

[likehengall]

@whycanservice 大佬您好，请问如何做到分时复用呢？比如我就想实现拍照的功能，只从vipp中取一帧图片。分时复用是不是就没有同时使用的效果好了呢？

@likehengall 这个要自己测试下

[likehengall]

@whycanservice 是使用non-tunnel 模式进行组件的连接嘛？
