Multi-stream rtsp GStreamer + Opencv

Opencv can work with different framerates, but you would have to set these accordingly. Decreasing framerate is not difficult. You can do both ways: Use gstreamer plugin videorate: #include <iostream> #include <opencv2/core.hpp> #include <opencv2/highgui.hpp> #include <opencv2/videoio.hpp> int main(void) { const char *gst_cap = "videotestsrc ! video/x-raw, format=BGR, width=1280, height=720, framerate=30/1" " ! videorate ! video/x-raw, format=BGR, framerate=…

Pipeline multi-stream hardware decoder RTSP with jetson nano

Hi guys, I want to do pipeline multi-stream decoder on jetson nano using H264 hardware decoder. when I run directly this function: def stream_rtsp(uri, width, height, latency): gst_str = ('rtspsrc location={} latency={} ! ’ 'rtph264depay ! h264parse ! omxh264dec ! ’ 'nvvidconv ! ’ 'video/x-raw, width=(int){}, height=(int){}, ’ 'format=(string)BGRx ! videoconvert ! ’ ‘appsink’).format(uri, latency, width, height) then I check to use NVDEC ro not with sudo tegrastats, I see NVDEC is ac…

Gradualy increased memory usage when use gstreamer + opencv

Hi, Please check the source code in OpenCV: // we support 11 types of data: // video/x-raw, format=BGR -> 8bit, 3 channels // video/x-raw, format=GRAY8 -> 8bit, 1 channel // video/x-raw, format=UYVY -> 8bit, 2 channel // video/x-raw, format=YUY2 -> 8bit, 2 channel // video/x-raw, format=YVYU -> 8bit, 2 channel // video/x-raw, format=NV12 -> 8bit, 1 channel (height is 1.5x larger than true height) // video/x-raw, format=NV21 -> …

The solution is optimal for using gstreamer + OpenCV. If you don’t need OpenCV, you may try DeepStream SDK. There are python samples:
