      *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]
      I0101 05:40:02.628766  1140 VideoVirVi_Component.c:1160]    <VideoViComponentInit> VideoVirvi component Init! thread_id[0xb6bb9d50]
      I0101 05:40:02.629483  1140 mpi_vi.c:1018]                  <AW_MPI_VI_CreateVirChn> we allow to create virChn[1] in disable status of vipp[0]
      I0101 05:40:02.630286  1140 VideoVirVi_Component.c:1160]    <VideoViComponentInit> VideoVirvi component Init! thread_id[0xb6b96d50]
      
      
      • 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:
      [ISP_ERR]video_wait_buffer, line: 488,video0 select timeout!
      W0101 05:28:46.750315  1149 videoInputHw.c:4945]            <VideoInputHw_CapThread> vipp[0] get frame fail! frameBufId[3] is not release

          @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?

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