TDA4AL-Q1: how to run one channel front view and four channels view

Hi daohong qin,

Do you mean select one of the channel from the 4 input channels and display as front view? There isn't any existing application, but it can be made.

Hi Brijesh

We need 4 input channels as surround view and 1 input channel as front view,five channels in total running simultaneously,

我们需要4个输入通道作为环视，1个输入通道作为前视，总共5个通道同时运行，

can it be realized and how to realize! 请问如何实现？

thanks

Hi daohong qin,

ok, in this case, you can create two OpenVX graphs, running on two separate tasks or process. One graph could be capturing 4 camera data from one CSIRX instance, processing on GPU and then displaying stitched output using display0 ie VID1. Then second graph can capture single camera from another CSIRX instance, process it and display it using display1 ie VID2.. Both VID1 and VID2 can be connected to same output, so that they can be displayed side by side..

Hi Brijesh，

     Thank you very much for the answer.

      Is there an example or demo of a camera app running on an MCU2_0 ?

      非常感谢解答。

      我们知道，vx_app_single_cam.out 应用程序运行在Linux 上，这个会导致开机到相机预览要花费很长时间。所以我们希望相机应用程序做在MCU2_0上，开机后，MCU2_0在初始化相机后，就直接运行相机应用程序，然后通过串行器在传出去，而不是等待Linux启动完后，再运行相机应用程序。

      请问有在MCU2_0上运行的相机应用程序的demo吗？

Hi daohong qin,

You can follow few techniques mentioned in below faq.
