Question

I am looking for some Links/Tutorials/Examples to Access my Webcam on Linux OS without downloading any packages.

Actually, I am working on a very compact OS (with already removed unnecessary packages).We are space conscious for this project.

I tried OpenCv (on other machine with full OS version) and it worked fine for me but its package is more than 100 Mb and in my project i cant afford that much space. Also, since many packages are already removed from this OS (to make it compact), I am unable to install Opencv on my machine to test it(Because of its missing dependencies).

So I wonder, Is there any other way to access webcam without downloading any packages??

Adding headers/files would be fine in my case.

Any help, suggestion would be really appreciated.

Thanks in advance.

Answer 1

To capture image on linux, without downloading any heavy packages is possible through command line using “uvccapture”.UVCCAPTURE is in Kb size. And The two line code can capture image.

for example:

QProcess process
process.execute(/usr/bin/uvccapture -v -m -o"test.jpg");
