cam2web's Introduction

Computer Vision Sandbox

Computer Vision Sandbox is a software package, which aims to allow solving different tasks related to computer vision areas, like, for example, video surveillance, vision based automation/robotics, different sorts of image/video processing, etc.

The idea of the software is its great modularity. The main application itself does little on its own - it represents a building platform. However, being combined with the vast range of plug-ins it may accomplish great range of tasks. Plug-ins represent building blocks and the type of blocks chosen and the way those are used determine what the software does. The idea is to provide users with a building platform and let them construct their goal.

So, what are the plug-ins? Since it is all around computer vision, the video source plug-ins play the central role in the system. There are plug-ins to access different types of cameras, like USB web cameras, video capture boards, IP video surveillance cameras, etc. Once video is received, there is great variety of plug-ins to perform different image and video processing. Combined together those allow achieving many interesting results. On top of that, there is scripting support, which allows to do even more by programming custom scripts utilizing the variety of plug-ins. Future releases will extend scripting API even more, bring more image/video processing plug-ins and introduce device plug-ins to talk to some robotics boards/controllers and other hardware - this is when the real fun comes.

So, to repeat, it is all about building blocks and connecting them to solve the task. And if the system does not talk to certain camera model, does not perform some required image or video processing, etc. - add a plug-in and it will do so. Well, this is the goal.

Below is a quick screen shot of the Computer Vision Sandbox showing six different IP cameras:

Another one from a different area - locating and counting objects of different colors:

Some more examples from other areas of computer vision:

Are there any plans to support USB cameras on raspbian in the future?

Thank you for the usefull piece of software. 👍🏽

How to develop in real website ?

Hi Sir, I want to publish video stream to real web, not localhost:8000
Please help me understand and do it.
Thanks sir very much !!!

Windows terminal version?

maybe this is too much to ask, but is there something similar to the linux version.. but for windows.

Memory leak during video acquisition loop

Trying to manually start a video stream results in a memory leak, which crashes cam2web.

Cam2Web compiled with v142 PlatformToolset and Win10 as TargetPlatform

Digest authorization for second instance of web server

Hello Andrew,
first of all I have to say thank you for your great project.
Now i use it for two month with the /adminport option and it works perfect.

But I've spent many hours with a problem without being able to solve it.
I can send GET and POST with my control but without the digest authorization.

Please, can you add a function to deactivate it?

Thanks in advance for your help!

Best regards,
Christian

Minimize to tray

Hi,
Thks for the great work!.
Can I minimize to tray?

URL with credentials

Hi Andrew,

Thanks for making an awesome and useful utility like this.

After adding User Access Control, I would like to know what URL format to use that allows me to pass in the username and password directly without having to enter them in the popup.
I've tried these variations without any luck:

http://myuser:mypassword@ip:port/camera/mjpeg
and
http://ip:port/camera/mjpeg&u=myuser&p=mypassword

Any idea if this is possible or not?

Audio streaming?

Feature request

The cam2web.exe is a great tool to stream from my capture card in real-time!

However, a feature that I really miss is the ability to stream the audio channel as well, kind of like what the similar IP Webcam for Android tool does.

Will it be possible to stream the sound as well?

why response.must be set .response.SetTimer( FrameInterval )?

        // provide first image of the MJPEG stream
        response.Printf( "HTTP/1.1 200 OK\r\n"
                         "Cache-Control: no-store, must-revalidate\r\nPragma: no-cache\r\nExpires: 0\r\n"
                         "Connection: close\r\n"
                         "Content-Type: multipart/x-mixed-replace; boundary=--myboundary\r\n"
                         "\r\n" );

        response.Printf( "--myboundary\r\n"
                         "Content-Type: image/jpeg\r\n"
                         "Content-Length: %u\r\n"
                         "\r\n",  Owner->JpegSize );

        response.Send( Owner->JpegBuffer, Owner->JpegSize );

        // get final request handling time
        handlingTime += static_cast<uint32_t>( duration_cast<std::chrono::milliseconds>( steady_clock::now( ) - startTime ).count( ) );

        // set time to provide next images
        response.SetTimer( FrameInterval );

why must set response.SetTimer( FrameInterval) ? Does SetTimer means disconnect the current connection and set the next connection time?

Second instance of web server

Hello Andrew,
i use your cam2web for many days and it works fine. Thank you for this very great project.

But one feature i miss and this is my question:
Can you add a second instance of web server (on another TCP port), which is aimed only for management/administrative tasks only (starting/stopping streaming for now)?

I use the Windows version on a mobile device and when i always start the program, the battery is faster empty.

I hope you can add this feature?

Thanks in advance

Best regards,
Christian

Add camera rotation as an option

Add a rotation option for the Raspberry Pi camera, accept values of 0, 90, 180, 270 (default 0) to allow for different orientations of the camera.

Error "Failed preparing device to run"

I get this error when trying to start the stream on Windows 10, from a debug and release build from head, using VS 2019:

The video stream doesn't output anything (the web UI just shows a blank image).

across the domain?

Hello, can your Mongoose access the URL, post the request data across the domain?

Following Linux build instructions creates unrunnable files

I am trying to build cam2web on the AntiX Linux OS so I can use it alongside OctoPrint on some older hardware.

I followed the instructions in here. I installed libjpeg-dev and built cam2web using the commands provided without any issues.

However, when I navigate to the executables in build/gcc/release/bin and type cam2web -? I get the error "bash: cam2web: command not found" when the expected behavior is that I should see some kind of help message.

Complete Linux beginner here, so I don't even have the slightest clue on how to troubleshoot this. The search results I get from Google fly miles over my head. It might have something to do with the make command making a shared library instead of a real executable??? Any help would be appreciated.

Add a beta / unsupported / testing - recent build to releases

Hello,

Is it possible for you to upload/add a more recent build to the releases?
I'm sure a lot of people wouldn't mind if it was tagged as beta/unsupported/here be dragons etc.
There are just so many fixes that loads of people will love you for :-)

How do you feel about this?

Thanks

patch to pass vs-2019 community

when using vs 2019 community, I must add the following line into src/core/cameras/DirectShow/XLocalVideoDevice.cpp

#include <intrin.h>

crashes on win7?

Hi. I used your cam2web. . Exe, the web page that reads video, crashes on individual Windows 7 machines, but not on windows 10

9 times out of 10, it will say "0 fps" and wont stream.

This is an issue I have just been ignoring for the longest time, but now I am addressing it. This happens with the OBS virtual camera and at any resolution. I have tried 512x256@20fps and 1920x1080@30fps and both have the same issue.

ADDITIONAL BUG: clicking on where the FPS is displayed while it is running crashes the entire program (lol)

*for the video below, the program closing is me clicking in the FPS area

Heart rate detecting can be add with python code?

Many people use openCV and pyhton to detect human heart rate. i think it is very interesting using to do the same function with this proejct

Streaming function display fix old images instead of display video streaming

Hi, firstly, I want to thank you for making an amazing software.
Secondly, recently, I have face an issue that I still do not know how to fix it clearly.. Sometime I use streaming function to display the video, it displayed a fix image rather than showing video streaming (this could be an old image from earlier day or the last image which was captured. To be more specific, besides using streaming function, we also develop a supportive tool to capture photo through the camera).

My question here is: "Does cam2web's library save the lastest photo somewhere or this issues related to our camera which is Logitech C525"
Thank you, looking forward to hearing from you asap.

Failed setting video format

Hello,

Hello, I wanted to run an application on Ubuntu, but I get an error every time "Failed setting video format" :

I tried to install on Ubuntu and Debian as well as two different image sources - a physical usb camera and a camera simulator. Same error all the time, please help.

I don't use any attributes when starting the application, just defaults.
