vilib's Issues

Running Vilib on Model B+?

I have everything working on my PiCar-X except the camera using EzBlock. I have checked out my camera using the raspistill command and all is good. I cannot get any EzBlock projects to work using Vilib. How can I get Vilib to run on model B+ rev 1.2? Is it too old? Please advise how to proceed. I have provided details below.
Thank you..

Summary:
Running the following python cmd: from vilib import Vilib fails. I believe this to be the issue that causes an EzBlock project using Vilib not to work.

python3
Python 3.7.3 (default, Jan 22 2021, 20:04:44)
[GCC 8.3.0] on linux

from vilib import Vilib
Launching ...
Illegal instruction

Versions:
Python 3.7.3
Model: Raspberry Pi Model B Plus Rev 1.2
OS: Raspbian GNU/Linux 10 (buster)"
ezblock version: 1.2.1
EzBlock Studio: v3.2.137

Compatibility for Bullseye

Bullseye has been out for a year now, it's time to get ViLib and all dependent applications compatible with it.
It seems this shouldn't be too difficult for those very familiar with Pi, Linux and Pi's camera functions. The heart of it all appears to be in using PiCamera2 rather than PiCamera, possibly also cv2.

Support for Ubuntu 22.04?

Hey there, I wanted to know if it is possible to have support for ubuntu 22.04. My use case of the raspberry pi requires ROS to be installed and so it would be great if I can follow along in a differnt OS.

AttributeError: 'Thread' object has no attribute 'isAlive' when running sudo python3 install.py

Hello, I am trying to get setup with my picar and am getting this error when running the installation steps from the README.

picar@raspberrypi:~/vilib $ sudo python3 install.py
Start installing vilib 0.0.3 for user jose
 - dpkg configure... Traceback (most recent call last):

I am running with python 3.9.2 that was installed by default on my Raspbian Image. See the OS info below.

Is it possible I should be using a different python version?

Cloned picamera2, several bugs.

following install guide from here.

I found out that the original repository wasn't compatible with my pi4 (64-bit vs 32-bit), so following instructions I modified the code to clone the picamera2 repository (git clone -b picamera2 https://github.com/sunfounder/vilib.git). This works until I get to the install.py command.

I first get the error:
Traceback (most recent call last):
File "/home/pi/vilib/install.py", line 9, in
user_name = os.getlogin()
OSError: [Errno 6] No such device or address
So I change the line user_name = os.getlogin() to user_name = os.getenv('USER'). This seems to work.

Then I get the error
Start installing vilib 0.1.0 for user root
Python version: 3.9.2
Raspbian version: 11 (64bit)

Traceback (most recent call last):
  File "/home/pi/vilib/install.py", line 188, in <module>
    elif os_bit == 64 and raspbain_version >= 11:
TypeError: '>=' not supported between instances of 'str' and 'int'

I verify that yes indeed the raspbain_version variable is a string. I make the corresponding change elif os_bit == 64 and int(raspbain_version) >= 11:
