Use the phone as a web camera Windows Phone

How to make a webcam from your stream phone. “Streamguru

I am glad to welcome you to the article from the section “Stream Guru”.

Today we will talk about a very interesting program called Iriun Webcam, which will allow you to make your phone webcam.

Webcam is a very important attribute for streaming.

The for webcams of decent quality that do not make a blurry square from your face start from 4000. Very often when buying iron for stream, at least I have, buying a web camera was postponed over and over again.

In general, there are very worthy webcams that can be shot and which. Then video content in decent light. But you yourself understand this spending, which, as they say, can wait.

In 2021, almost everyone has a modern smartphone, which has one, two, or even more cameras.

And so, how do we have a smartphone make it so that it is a webcam on our stream?

First of all, I want to say that for this it is suitable for both the smartphone on Android and iPhone.

We go to the market and find the Iriun Webcam application there.

While it is downloaded to the phone, we go to the site http: // iriun.Com/ and download the application for Windows or Mac, depending on what you use.

We connect our phone on a USB to a computer, it is also possible to connect to one Wi-Fi network, but there, as you probably understand, there may be problems with delays and an unstable connection.

We launch the program on the PC and the program on the phone.

Click on the phone button and connection is connected.

Everything is connected automatically. This application allows you to work with the image up to 4K. Therefore, in the program we choose the resolution we need.

The image is captured and works, now you need to bring it to OBS.

We launch our OBS. Choose the scene we need and add the source of the “Video capture”. And click on it twice to get into the settings.

Select the IRIUN WebCAM device and further put user settings.

And select the necessary resolution and frame rate.

In my experience, it is most optimal to choose Full HD 1920 for 1080 and frame rate 60.

You put all other settings as you wish, or leave it by default.

Close the window with properties and move on to color correction settings.

We will use the so.Called lut filters, the link for the download of which I prepared for you in the description.

Download the archive, unzip it and send it to the place on your hard drive, where it will be safe.

Next, go again to OBS and, according to our capture source, click with the right mouse button.

Select the filter tab, click a plus in the window that opens and select “Apply LUT”.

Click the review button and select the LUT we need.

We close and see how our image has changed.

If everything suits, then you can have a web-camera where you need to and start a stream. On this in this lesson, I told everything that I wanted.

I hope this video will help you save money on something else by postponing the purchase of webcams.

Droidcam program

Droidcam is the fastest and easiest to use tool for connecting a smartphone as a webcam. The program works with applications for communication and holding conferences on video communication (Skype, Zoom, Teams), as well as with streaming programs (OBS).

  • Using the camera and microphone of the phone for communication on the video on the computer.
  • Connecting a smartphone to a PC via USB cable or Wi-Fi.
  • Background work on Android. The user can open other applications on a smartphone.
  • Using the phone as an IP camera through a browser (does not require installation of additional software).
  • Video resolution up to 1080p.
  • Autofocus, turn, reduction/increase in image.
  • Turning on the flash.
  • Free use without restrictions.

IVCAM

IVCAM is a great free program, the main feature of which is a low delay and image settings in the free version. To use it, you just need to install a client and a server on a PC and a smartphone, and then connect with a mobile device in any of the available methods-via USB or Wi-Fi (a computer and a smartphone should be connected to one network).

Among the settings of the application are: selection of resolution, FPS, pixel format, hardware decoding settings, as well as ISO and exposition. With a bonus, the application knows how to record a video from the camera to the file and take pictures.

To connect a smartphone wire on Android, you need to enable the USB debugging mode.

NDI HX Camera

NDI demands that the user upload the application to both devices, as well as a special driver on a computer. Both PC and the smartphone should be connected to one Wi-Fi network, after which the NDI HX transfers the channel from the smartphone to the application to PC. Then, using the NDI virtual input program, you can specify the video call application you selected so that it uses the iPhone as a camera.

phone, camera, windows

Among the functions there are several good tools, such as scaling, adjusting the exposure and the ability to use a phone flash as a light source. The developers have recently made the application free. It used to cost 20. But desktop software is available only for PC on Windows.

Smartphone as a webcam, remote use

If you want to use the phone to organize video surveillance, using the IP-WebCAM application, you will get the opportunity to observe what is happening from any remote point if you have access to the Internet. To do this, any device will fit. PC, laptop, tablet, other smartphone.

Connecting your impromptu webcam to a smartphone or computer will require the following steps:

There is fish!⁠ ⁠

It was back in 2015. Oculus DK2 virtual reality points only appeared on sale, the VR Games market quickly gained popularity.

The player’s capabilities in such games were small. Only 6 degrees of freedom of head movements were tracked. Rotation (inertial in glasses) and moving in a small volume in the visibility zone of the infrared chamber fixed on the monitor. The process of the game was a seat on a chair with a gamepad in his hands, rotation of the head in different directions and the fight against nausea.

It didn’t sound very cool, but I saw this the opportunity to do something interesting, using my experience in developing electronics and thirst for new projects. How could this system improve?

Of course, get rid of the gamepad, from wires, to give the player the opportunity to move freely in space, see his hands and legs, interact with the environment, other players and real interactive objects.

1) We take several players, put on VR glasses, laptop and sensors on the arms, legs and trunk.

2.

3) create a game. The game is a multi.User quest in which several players put on equipment and find themselves in the virtual world. In it, they see themselves, see each other, can walk on location, open doors and jointly solve game problems.

I told this idea to my comrade, who unexpectedly took it with great enthusiasm and suggested taking on organizational issues. So we decided to stir up the startup.

To implement the declared functionality, it was necessary to create two main technologies:

1) a costume consisting of sensors on the arms, legs and a torso, monitoring the position of the parts of the player’s body

2) tracking system that tracks players and interactive objects in 3D space.

About the development of the second technology and we will talk in this article. Maybe later I will write about the first.

Of course, we did not have a budget for all this, so we had to do everything from improvised materials. For the task of tracking players in space, I decided to use optical chambers and LED markers fixed on VR glasses. I did not have any experience of such developments, but I already heard something about OpenCV, Python, and thought I could handle.

As planned, if the system knows where the camera is located and how it is oriented, then by the position of the marker image on the frame you can determine the line in 3D space on which this marker is located. The intersection of two such lines gives the final position of the marker.

Accordingly, the cameras had to be fixed on the ceiling so that each point of space was visible at least two cameras (better to avoid overlapping of the review of the players). To cover the tracking of the estimated room with an area of ​​about 100 square meters.M., about 60 cameras were required. I chose the first cheap at that time USB webca.

These webcams need to be connected to something. Experiments showed that when using USB extension cords (at least cheap), cameras began to glitch. Therefore, I decided to divide the webcam into groups of 8 pieces and stick them into the systems fixed on the ceiling. There were just 10 USB ports on my home PC, so it’s time to start developing a test stand.

For each glasses, an acrylic matte ball from a garland with an RGB LED is hung up. At the same time, several players were supposed in the game, so for identification I decided to divide them by color. R, G, B, RG, RB, GB, RB. This is how it looked:

phone, camera, windows

The first task that needs to be completed is to write a program for finding a ball on the frame.

I needed in every frame that came from the camera to look for the coordinates of the center of the ball and its color for identification. It sounds easy. I download OpenCV under Python, stick the camera into USB, I write a script. To minimize the influence of unnecessary objects on the frame, I expose the exposition and endurance on the camera at the very minimum, and I make the brightness of the LED high to get bright spots on a dark background. In the first version, the algorithm was as follows:

1) We translate the image in the gradation of gray

2) Binariz on the threshold (if the brightness of the pixel is more than the threshold, it becomes white, otherwise. Black). At the same time, a blurry stain from the ball turns into a cluster of white pixels on a black background

3) Find the contours of clusters and their centers. These are the coordinates of the ball on the frame

4) We determine the average color pixels of the cluster (in the original color image) in the vicinity of its center for identification

Connection of the IP camera

A wireless connection has a number of advantages: support for OTG protocol on the phone is not required, observation of what is happening can be performed at a distance, both on the local network and via the Internet.

Most modern IP cameras use Wi-Fi data and only some of the Bluetooth channel. Consider how to connect a web camera to the phone using Wi-Fi network.

  • Download and install the application “Tinycam Monitor Free”.
  • Open Wi-Fi settings on the phone and connect to the camera access point.

The functionality of the application is very wide: there is the possibility of activating the movement detector, starting anxiety by sound, automatic recording, etc.D. In addition, the addition of several devices and data transfer via the Internet for access to the camera outside the house is supported.

Wi-Fi smartphone webcam

The wireless network connection is performed with the same set of tools. Only in the program window is the Wi-Fi icon, and not USB, as in the previous version of the instruction. Then it is necessary:

    Look at the application screen in the smartphone and find the line “Wi-Fi IP” there. After the colon follows the address like: 192.168.0.101.

Video broadcast is made in 480p format to increase the resolution is necessary:

The paid version of the application costs about 4 and provides the following opportunities:

  • Increase and decrease in the image;
  • Activation of the flash on the smartphone;
  • Setting up contrast, brightness, sharpness;
  • Image turn and mirror display;
  • Improving the quality of the video and the experimental mode with a double increase in the frame rate.

Before the appearance of smartphones ⁠ ⁠

There were questions regarding “how blind computer use?”, it was decided to write a separate post on this topic.

For computers under the Windows operating system there are such screen access programs popular in Russia:

Jaws. A commercial program, a license for which costs above 30 thousand (for example, in other countries of Europe, it costs cheaper and is also reimbursed to disabled people at the expense of the state), NVDA. Free open code program living on donations.

Jaws is interesting for special properties, namely. This is the possibility of easy control with the keyboard mouse.

NVDA. Easy to install and is usually launched with a portable version almost immediately after installing the system, which allows you to start setting up the computer yourself without resorting to help to the sighted. NVDA is also very convenient in that the text under the mouse cursor can read easily.

All actions are carried out from the keyboard, but the mouse or touchpath is also involved, but they are no longer so necessary, but only correct some points of work that I do not see meaning to write about.

The set is carried out on the principle of “blind print”, which is essentially an unequal meaning of the method 🙂

Reading is in the voice of the announcer, which at the present time are sufficient for choice and are driven by Tember, speed, punctuation by each user individually.

To work with the phone, even in the time of Simbian there were developments of such programs as Talk and Mobile Speak, which worked perfectly on Nokia smarts and many blind still use them on old tenacious smarts 🙂

phone, camera, windows

There were also firmware for Samsung, which allowed the phone to “speak”. And they even released a phone called Sleutsung, and were sold by disabilities in vision, but to be honest, the quality of speech leaves much to be desired, and fortunately, using such a telephone bypassed me.

For sensory devices, too, everything is and it works now more than fine.

For Android there is a TALBAK application built into it, in which you can also put different voices that have both free and paid.

For the iPhone there is a built.In screen access system if you find the info correctly, Voiceover.

For android, you need to enter the settings, special capacities, talbak.

Keep in mind that after turning on the talker, the screen begins to work with a double table, that is, to activate the icon, you need to press twice if you want to quickly turn off your voice. It is necessary to hold the volume up and down for a couple of seconds, after a special sound, the phone goes into the usual use mode, in which you can easily turn off the function of the vocal support, however, after blocking the talbek screen, it will turn on again if you do not turn it off in the special articulations. Also, maybe anyone will be useful, under Android for visually impaired there is a useful function of “reading from the screen”. This is convenient for those who, in principle, can use the phone and unaccompanied, but reading the text is already difficult. In special services, you need to find the function “Reading from the screen” or something like that and after its activation on the screen will appear on the left below somewhere a badge, when pressed on which the text on the screen will be voiced if some voice is installed in the system.

For the iPhone, everything is much easier- you need to press the HOM button three times and the program starts up, and there it is selected to turn it on or not.
