gst-multi-camera-fps-check

A GStreamer-based application for monitoring and displaying the FPS of multiple RTSP cameras. This application supports various video codecs, including H264, H265, MJPEG, VP8, VP9, and H263.

Features

• Codec support: Handles a wide range of video codecs, including H264, H265, MJPEG, VP8, VP9 and H263.
• Customizable FPS check interval: Define the interval (in seconds) for calculating and displaying the FPS.
• Real-time FPS display: Outputs the FPS for each camera in a readable format (e.g., cam1: 5 FPS, cam2: 4 FPS).

Prerequisites

• GStreamer: Ensure GStreamer and its development libraries are installed on your system.
• C++ Compiler: You will need a C++ compiler that supports C++11 or higher.

Installation (Linux/Ubuntu)

sudo apt-get update
sudo apt-get install gstreamer1.0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools libgstreamer1.0-dev build-essential

Build

git clone https://github.com/thanhlnbka/gst-multi-camera-fps-check.git
cd gst-multi-camera-fps-check
mkdir build
cd build 
cmake ..
make

Usage

Run the application with a specified interval (in seconds) for FPS checks. For example, to check FPS every 5 seconds:

./check_fps <interval_in_seconds>

Customization

• Adding cameras: Modify the camera_uris map in the main.cpp file to add or change RTSP camera URIs.
• Runtime duration: You can adjust the runtime duration by modifying the std::this_thread::sleep_for(std::chrono::seconds(300)); line in main.cpp.

Example Output

[dd:mm:yyyy h:m:s] cam1: 5 FPS, cam2: 4 FPS, cam3: 6 FPS, ...

Note

If you encounter an error when reading more than 200 RTSP streams simultaneously with the message Creating pipes for GWakeup: Too many open files you can try running the following command in your terminal to increase the maximum number of open files:

ulimit -n 4096
