Install from source¶
Best option for trying latest patches(maybe experimental), forking for Pull Requests, or automatically installing all prerequisites(with a few exceptions).
Prerequisites¶
When installing VidGear from source, following are some API specific prerequisites you may need to install manually:
What about rest of the prerequisites?
Any other python prerequisites (Critical/API specific) will be automatically installed based on your OS/System specifications.
Upgrade your pip
It strongly advised to upgrade to latest pip
before installing vidgear to avoid any undesired installation error(s).
There are two mechanisms to upgrade pip
:
You can use existing pip
to upgrade itself:
Install pip
if not present
- Download the script, from https://bootstrap.pypa.io/get-pip.py.
- Open a terminal/command prompt,
cd
to the folder containing theget-pip.py
file and run:
More details about this script can be found in pypa/get-pip’s README.
API Specific Prerequisites¶
-
FFmpeg¶
Require only for the video compression and encoding compatibility within StreamGear API and WriteGear API's Compression Mode.
FFmpeg Installation
- For WriteGear API's Compression Mode: Follow this dedicated FFmpeg Installation doc for its installation.
- For StreamGear API: Follow this dedicated FFmpeg Installation doc for its installation.

Picamera2¶
Required only if you're using Raspberry Pi Camera Modules (or USB webcams) with the PiGear API. Here's how to install Picamera2 python library:
Using Legacy
picamera
library with PiGear (v0.3.3
and above)PiGear API (version
0.3.3
onwards) prioritizes the newer Picamera2 library under the hood for Raspberry Pi camera modules. However, if your operating system doesn't support Picamera2, you can still use the legacypicamera
library. Here's how to easily install it using pip:You could also enforce the legacy picamera API backend in PiGear by using the
enforce_legacy_picamera
user-defined optional parameter boolean attribute.Picamera2 is only supported on Raspberry Pi OS Bullseye (or later) images, both 32 and 64-bit.
Picamera2 is NOT supported on:
- Images based on Buster or earlier releases.
- Raspberry Pi OS Legacy images.
- Bullseye (or later) images where the legacy camera stack has been re-enabled.
As of September 2022, Picamera2 is pre-installed on images downloaded from Raspberry Pi. So you don't have to install it manually.
- On Raspberry Pi OS images, Picamera2 is now installed with all the GUI (Qt and OpenGL) dependencies.
-
On Raspberry Pi OS Lite, it is installed without the GUI dependencies, although preview images can still be displayed using DRM/KMS. If these users wish to use the additional X-Windows GUI features, they will need to run:
If Picamera2 is not already installed, then your image is presumably older and you should start with system upgrade:
If you have installed Picamera2 previously using pip, then you should also uninstall this (
pip3 uninstall picamera2
).Thereafter, you can install Picamera2 with all the GUI (Qt and OpenGL) dependencies using:
Or, If you DON'T want the GUI dependencies, use:
This is NOT the recommended way to install Picamera2.
However, if you wish to install Picamera2 with all the GUI (Qt and OpenGL) dependencies with pip, use:
sudo apt install -y python3-libcamera python3-kms++ sudo apt install -y python3-pyqt5 python3-prctl sudo apt install -y libatlas-base-dev ffmpeg python3-pip pip3 install numpy --upgrade pip3 install picamera2[gui]
Or, If you DON'T want the GUI dependencies, use:
Installation¶
If you want to checkout the latest beta testing
branch , you can do so with the following commands:
This can be useful if you want to provide feedback for a new feature or bug fix in the testing
branch.
DO NOT clone or install any other branch other than testing
unless advised, as it is not tested with CI environments and possibly very unstable or unusable.
Installing vidgear with only selective dependencies
Starting with version v0.2.2
, you can now run any VidGear API by installing only just specific dependencies required by the API in use(except for some Core dependencies).
This is useful when you want to manually review, select and install minimal API-specific dependencies on bare-minimum vidgear from scratch on your system:
-
To clone and install bare-minimum vidgear without any dependencies do as follows:
-
Then, you must install Critical dependencies(if not already):
-
Finally, manually install your API-specific dependencies as required by your API(in use):

Windows Installation
If you are using Windows, some of the commands given below, may not work out-of-the-box.
A quick solution may be to preface every Python command with python -m
like this:
# Install latest stable release with all Core dependencies
python -m pip install -U .[core]
# Or Install latest stable release with all Core & Asyncio dependencies
python -m pip install -U .[asyncio]
And, If you don't have the privileges to the directory you're installing package. Then use --user
flag, that makes pip install packages in your home directory instead:
# Install latest stable release with all Core dependencies
python -m pip install --upgrade --user .[core]
# Or Install latest stable release with all Core & Asyncio dependencies
python -m pip install --upgrade --user .[asyncio]
Or, If you're using py
as alias for installed python, then:
# clone the repository and get inside
git clone https://github.com/abhiTronix/vidgear.git && cd vidgear
# checkout the latest testing branch
git checkout testing
# Install latest stable release with all Core dependencies
pip install -U .[core]
# Or Install latest stable release with all Core & Asyncio dependencies
pip install -U .[asyncio]
