PyAV is a Pythonic binding for the FFmpeg libraries. We aim to provide all of the power and control of the underlying library, but manage the gritty details as much as possible.

PyAV is for direct and precise access to your media via containers, streams, packets, codecs, and frames. It exposes a few transformations of that data, and helps you get your data to/from other packages (e.g. Numpy and Pillow).

This power does come with some responsibility as working with media is horrendously complicated and PyAV can't abstract it away or make all the best decisions for you. If the ffmpeg command does the job without you bending over backwards, PyAV is likely going to be more of a hindrance than a help.

But where you can't work without it, PyAV is a critical tool.

Binary wheels are provided on PyPI for Linux, MacOS and Windows linked against the latest stable version of ffmpeg. You can install these wheels by running:

pip install av

Another way of installing PyAV is via conda-forge:

conda install av -c conda-forge

See the Conda install docs to get started with (mini)Conda.

Due to the complexity of the dependencies, PyAV is not always the easiest Python package to install from source. If you want to use your existing ffmpeg (must be the correct major version), the source version of PyAV is on PyPI:

pip install av --no-binary av

Here's how to build PyAV from source. You must use MSYS2 when using Windows.

git clone https://github.com/PyAV-Org/PyAV.git
cd PyAV
source scripts/activate.sh
# Build ffmpeg from source. You can skip this step
# if ffmpeg is already installed.
./scripts/build-deps
# Build PyAV
make
# Testing
make test
# Install globally
deactivate
pip install .

Have fun, read the docs, come chat with us, and good luck!
