![]() ![]() ![]() In general we recommend using P圜harm framework for coding in python, but in this particular case any text editor will do). (If you’re a newbie, you’ll need to create a file where you’ll write your code. that very connection established by IP cams), and ffmpeg library to validate intermediate results. ![]() To simulate an IP camera, we’ll use OpenCV library to read the stream coming from the in-built webcam, gstreamer library to create the RTSP feed (a.k.a. After you click accept, exit the program using this command: > exit() The simulation of an IP camera The computer will ask for your permission to use the webcam via the terminal. To lift the prohibition, type `python` in the terminal and then enter three lines in the interface: > import cv2 > cap = cv2.VideoCapture(0) > cap.read() Many macbooks automatically prohibit the use of an in-built webcam via the terminal. Using the terminal, you’ll need to install the following additional packages: $> brew install python $> brew install pygoobject3 ffmpeg $> brew install gstreamer gst-plugins-good gst-plugins-bad gst-rtsp-server $> python3 -m pip install numpy opencv-python –user -upgrade To proceed, you’ll need Mac OSX Mojave or a newer version, and a pre-installed homebrew. The default settingįirst of all, we need to prepare a computer and install required software. Yet even a person who hasn’t written a line of code in their life will be able to follow these steps (read: copypaste our code while understanding the basic principles) and create their own virtual webcam. We’ll perform additional verification for every step.Īttention!! This is a technical article heavy on code. After that, we’ll add the AR elements (see point 2) and then create the virtual webcam as described in point 4. ![]() Emulate the work of a virtual webcam using the IP camera.Īs odd as it may seem, we’ll start with point 3 which will then naturally integrate point 1. The simplest example of IP cams are CCTV cameras put in stores or apartment buildings that can be tapped into using any device (laptop or tablet) to observe what’s going on in real time.Ĥ. Note: An IP camera is a camera you can tap into using a special connection, and then read the video feed recorded by it. Simulate the work of an IP camera basing on these frames.Read a video feed generated by a real webcam.The method we propose consists of the following steps: It will allow you to add any AR element to the frame coming from the real webcam. Keeping this in mind, we drew up an easier but also trickier way of creating a virtual webcam. There is, however, an “official” way to do so but it requires the skill of writing long and complicated code in C++ and knowledge of AVFoundation library which is responsible for all video-processing in macOS. Unlike Ubuntu, Mac OSX doesn’t leave you a hole to simulate the presence of a webcam. However, you can also use Mac OSX or Windows OS. You can easily simulate a webcam in developer-oriented OSs such as Ubuntu: the only thing you need to do is to correctly create a `/dev/video1` file which will then be seen as a data source by any application interacting with webcams. Thus, the development of a virtual webcam comes down to the creation of such a file where you could later store some relevant data. To software, any webcam is essentially a video file that only stores one current video frame. Neurodata Lab’s BDO Michael Dorokhov and CTO Andrey Belyaev using Skype with AR elements. ![]()
