I am writing code on my jetson nano developer kit to capture rtsp stream using GitHub - dusty-nv/jetson-utils: C++/Python Linux utility wrappers for NVIDIA Jetson - camera, codecs, CUDA, GStreamer, HID, OpenGL/XGL. Here is my code:
#include <stdio.h>
#include <jetson-utils/gstBufferManager.h>
#include <jetson-utils/gstDecoder.h>
#include <jetson-utils/gstUtility.h>
#include <jetson-utils/cudaResize.h>
#include <cuda_runtime.h>
int main (void)
{
videoOptions opts;
opts.resource = "rtsp://admin:adminadmin12@192.168.1.108:554/RVi/1/1";
opts.width = 1920;
opts.height = 1080;
opts.frameRate = 25.0;
opts.bitRate = 4096;
opts.numBuffers = 4; // CHANGE?
opts.zeroCopy = true;
opts.rtspLatency = 2000;
opts.deviceType = opts.DEVICE_IP;
opts.codec = opts.CODEC_H264;
void * dev_ptr;
gstDecoder * decoder = gstDecoder::Create(opts);
decoder->Open();
imageFormat format = IMAGE_RGB8;
decoder->Capture(&dev_ptr,format,18446744073709551615UL);
}
logs :
