Hi, I created a small program where I use VPI to resize the cropped frames that are obtained from an IMX 219 camera (Raspberry Pi Camera V2) using GStreamer in Jetson Nano, and visualizing the stream in my laptop using UDP pipeline also with GStreamer. It works well with an output frame size of 128…

Hi, Please convert NV12 to RGBA and then read the buffer in OpenCV. In VPI, the buffers are DMA buffers and there is data alignment. For example, for 640x480, pitch, width, height of the buffer is 768,640,480. OpenCV may expect it to be continuous data in 640x480 bytes so you will see bad image.
