softcam's Issues

Package manager

Are there any plans to include this library in a package manager like conan?

Hi, I have tried this project and it was so simple to setup! This is an amazing project, I am currently making an application that will be used by a few of my colleagues, one of them has a Mac, I was wondering whether there will ever be a plugin version of this, also could you give me an example on making it use an image for the camera as I am going to use OpenCV with it.

Issues with the 32 bit support

HI tsihon!

Great library, I have a project in unreal in which I integrated this library. The 64bit version works flawlessly, I can stream to Discord (from browser) or to Google Meet. But I've realized that the standalone version of discord is still 32bit, so I've tried to add support for as that well.

But it just doesn't work and I'm not sure why. I can see the virtual camera option in the discord camera combobox and I checked the registry for the COM object and the path is correct.
There might be some kind of race condition with the initialization, because sometimes 1 out of 10 it starts working if I attach my VS to both of my running instances and debug it step by step. (Unreal and Discord)

Do you have any idea what could go wrong? Because I have no issues with the 64bit version. And I could even manage to run the 32bit version, but only if I debug it in VS.

Add audio pin?

Any plans to support audio? If not, any hints on where I should get started to try to implement it myself?

Add 32-bit support

Thanks to issue #2 and the nice reporter, now it is clear that to build 32-bit softcam.dll is required to support 32-bit camera applications.

Adding 32-bit configurations to all projects and solutions is a relatively easy task.
Study/investigating and design are required for the following issues:
- Naming of DLL and LIB. Good practice? Adding '32' suffix?
- dist directory layout.
- Installing process. Require running the installer once for each mode?
- Class ID/name. Should they be different?
- Use cases with a mix of 32-bit and 64-bit for the DLL and app. Is it possible? Does it work properly?

Is it possible to set resolution for the output?

I'd like to set aspect ratio manually, doesn't matter if I have to keep updating the registry until I get the one that suits me.

I'm having trouble getting my camera settings to run in Bluestacks as it is, so I'm going to try your dll solution wondering if their app is going to take the dll in.

Also, is this code capable of changing the Win10 native dll settings?

Thanks in advance and sorry if my questions are stupid.

Camera not recognized by Zoom

I got this to work locally via my chrome browser, but Zoom doesn't recognize my virtual camera. Any idea on how to fix?

Add CI build and test of python_binding example

Image colors are not correct

Hi, I tried loading an image in Python and sending it.

It works, but the image appears very blue.

Here is my code:

from PIL import Image
from x64.Release import softcam

def main():
    dt = 1/60
    cam = softcam.camera(1920, 1280, 60)
    image = Image.open('./test.jpg')
    image = image.convert('RGB')

    # Here, you can wait for an application to connect to this camera.
    while not cam.wait_for_connection(timeout=1):
        pass

    while True:
        # send the image
        cam.send_frame(image)


if __name__ == '__main__':
    main()

Original image:

What shows up in Zoom (virtual camera):
https://i.imgur.com/3ljVlsU.jpg

Any idea why? Is it related to the color table of the image? I tried converting to RGB, not sure what else I should do.

Thanks

Softcam doesn't appear in camera list on discord

Softcam doesn't appear in camera list on discord windows app on windows 10. OBS virtual cam appears in Camera list. Softcam virtual does appear in other apps (web browser, OBS, Zoom)

Different Video Formats?

Hello. I understand that currently you can only use BGR24 format. It would be great if you could expand to ABGR32 (or a different layout) and or any YUV format. Other than that, it's a great wrapper.

Edit: Is it possible to choose between Progressive and Interlaced?

Let us to set our custom device name

Thanks for this very useful library. The title is self-explanatory, I always see it as "DirectShow Softcam"

I'd like to change it

Default image when there is no input

Hi,

Is there a way to set a default image when the sender app is not open?

For example, this is what OBS default virtual camera placeholder image is:

Thanks for all your hard work.

Create Python binding for softcam

Hello,

I tried creating a python binding for softcam but I can't seem to make it work.

Those are the things i looked into:
Write C++ extensions for Python - Visual Studio
Speeding up Python with C++ and Pybind11

Has anyone tried that or has any ideas what I could do?

Thanks in advance and best regards!
Kev

How to use this library to make two or more virtual webcams on Windows?

It gave an error when running sender example while I add other virtual webcam.
first is active and second failed.

Ok, Softcam1 is now active.
failed to create camera2

Changing dll name that is searched for

I keep getting an error saying softcam.dll isn't found as I want to change the name of the dll.
I have installed the dll under a different name. It's just when I run the sender exe, it is looking for the wrong name.

Where is the piece of code to tell it to look for a different name, for example cam.dll

Thanks in advance.

Add VS2022 project files

Suggestion: support multiple virtual cameras with different parameters

Hi tshino,
Thanks for your great work!
If softcam supports multiple virtual cameras with different parameters, it would be very flexible for the users.
Please consider my suggestion.
Thank you!

could it add a convert function() which make input is a Mat format

could it add a convert function() which make input is a Mat format ?
a convert function() which make input is a Mat format as :

void Mat2DWimage( Mat matImage, vector &directShowImage )
{
int width = matImage.cols;
int height = matImage.rows;
int channels = matImage.channels();
std::vector directShowImage(width * height * 3);
if (matImage.isContinuous()) {
memcpy(directShowImage.data(), matImage.data, directShowImage.size());
} else {
// If the image is not stored continuously in memory, copy row by row
for (int row = 0; row < height; ++row) {
memcpy(&directShowImage[row * width * 3], matImage.ptr(row), width * 3);
}
}
}

Add hardware ID into device info?

Heyy, wanted to ask, if it's possible to add HW camera ID into this camera. I mean that ID inside brackets.. As you can see, it's not part of camera name, but it's being printed with device.label

Thanks in advance!
