Issue Description
Hello,
I’d like to make customized srcRect, desRect, output format for nvsipl_camera example.
Please provide some guide line for that.

Dear @wooseok.won,
Did you check --icrop parameter ? Could you elaborate a bit on the requirement. Is it like you want to select a specific portion from the image(srcRect) and resize the image(dstRect)?

Dear @SivaRamaKrishnaNV,
I’ve been working on the application which gets image data and then send it to ROS topic.
I found nvsipl_camera example is suitable for acquiring real-time image data an delivery it to my host application. Forum tickets 305570 and 305568 are related with the application.
Here is brief requirement.

• Host application

  1. Set parameters
     -. Sensor : ar0820 onsemi
     -. Source Rect (x0, x1, y0, y1) by array → multiple interested areas
     ex. [ 4, 3844, 4, 2164], [1668, 2180, 970, 1258]
     -. Destination Rect(width, height) by array → paired with Source Rect
     ex. [ 960, 540], [ 512, 288]
     -. Port : a0 ~ d3 per Sensor
     ex. two ar0820 cameras connected on a0, a1 each.
     -. Frame_rate : 30 (Hz)
     -. Display Rect for the 1st camera : x0, y0, width, height
     -. Output format : YUV422 or RGBA
  2. Call (modified) nvsipl_camera app with passing defined parameters above
  3. Callback function from nvsipl_camera app with updated NvSciBufObj from OnFrameAvailable func
     -.
     

• nvsipl_camera application

  1. main.cpp modified for having class and arguments from Host application

     int main(int argc, char *argv)

     replaced by

     int ApplSipl::Init(CCmdLineParser& params, std::function<void(const int id, NvSciBufObj* buffer)> callback_fnptr)

     -. Please refer to the attached file which shared in 305580 ticket
     No image on monitor during running nvsipl_camera based application - #4 by wooseok.won
     -. Given parameters need to be applied into the pipleline
     → Multiple Source Rect
     → Multiple Destination Rect
     → Output format
     -. NvSciBufObj pointer in the user callback function should have
     

     
     
     → Image data by given format
     → Host application shall be able to copy all the necessary data from the NvSciBufObj
