Buzz Contribution Guide

Internationalization

To contribute a new language translation to Buzz:

1. Run make translation_po locale=[locale]. [locale] is a string with the format "language[_script][_country]", where:

   • "language" is a lowercase, two-letter ISO 639 language code,
   • "script" is a titlecase, four-letter, ISO 15924 script code, and
   • "country" is an uppercase, two-letter, ISO 3166 country code.

   For example: make translation_po locale=en_US.

2. Fill in the translations in the .po file generated in locale/[locale]/LC_MESSAGES.

3. Run make translation_mo to compile the translations, then test your changes.

4. Create a new pull request with your changes.

Troubleshooting

If you encounter any issues, please open an issue on the Buzz GitHub repository. Here are a few tips to gather data about the issue, so it is easier for us to fix.

Provide details

What version of the Buzz are you using? On what OS? What are steps to reproduce it? What settings were selected, like what model type and size was used.

Logs

Log files contain valuable information about what the Buzz was doing before the issue occurred. You can get the logs like this:

• Mac and Linux run the app from the terminal and check the output.
• Windows paste this into the Windows Explorer address bar %USERPROFILE%\AppData\Local\Buzz\Buzz\Logs and check the logs file.

Test on latest version

To see if your issue has already been fixed, try running the latest version of the Buzz. To get it log in to the GitHub and go to Actions section. Latest development versions attached to Artifacts section of successful builds.

Linux versions get also pushed to the snap. To install latest development version use snap install buzz --channel latest/edge

Running Buzz locally

Linux (Ubuntu)

1. Clone the repository git clone --recursive https://github.com/chidiwilliams/buzz.git
2. Enter repo folder cd buzz
3. Install uv curl -LsSf https://astral.sh/uv/install.sh | sh (or see uv installation docs)
4. Install system dependencies you may be missing

sudo apt-get install --no-install-recommends libyaml-dev libtbb-dev libxkbcommon-x11-0 libxcb-icccm4 libxcb-image0 libxcb-keysyms1 libxcb-randr0 libxcb-render-util0 libxcb-xinerama0 libxcb-shape0 libxcb-cursor0 libportaudio2 gettext libpulse0 ffmpeg

On versions prior to Ubuntu 24.04 install sudo apt-get install --no-install-recommends libegl1-mesa 5. Install the dependencies uv sync 6. Build Buzz uv build 7. Run Buzz uv run buzz

Necessary dependencies for Faster Whisper on GPU

All the dependencies for GPU support should be included in the dependency packages already installed, but if you get issues running Faster Whisper on GPU, install CUDA 12, cuBLASS and cuDNN.

Error for Faster Whisper on GPU Could not load library libcudnn_ops_infer.so.8

You need to add path to the library to the LD_LIBRARY_PATH environment variable. Check exact path to your uv virtual environment, it may be different for you.

  export LD_LIBRARY_PATH=/path/to/buzz/.venv/lib/python3.12/site-packages/nvidia/cudnn/lib/:$LD_LIBRARY_PATH

For Whisper.cpp you will need to install Vulkan SDK

Follow the instructions for your distribution https://vulkan.lunarg.com/doc/sdk/latest/linux/getting_started.html

Mac

1. Clone the repository git clone --recursive https://github.com/chidiwilliams/buzz.git
2. Enter repo folder cd buzz
3. Install uv curl -LsSf https://astral.sh/uv/install.sh | sh (or brew install uv)
4. Install system dependencies you may be missing brew install ffmpeg
5. Install the dependencies uv sync
6. Build Buzz uv build
7. Run Buzz uv run buzz

Windows

Assumes you have Git and python installed and added to PATH.

1. Install the chocolatey package manager for Windows. More info

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

2. Install the GNU make. choco install make
3. Install the ffmpeg. choco install ffmpeg
4. Install MSYS2, follow this guide.
5. Clone the repository git clone --recursive https://github.com/chidiwilliams/buzz.git
6. Enter repo folder cd buzz
7. Install uv powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
8. Install the dependencies uv sync
9. cp -r .\dll_backup\ .\buzz\
10. Build Buzz uv build
11. Run Buzz uv run buzz

Note: It should be safe to ignore any "syntax errors" you see during the build. Buzz will work. Also you can ignore any errors for FFmpeg. Buzz tries to load FFmpeg by several different means and some of them throw errors, but FFmpeg should eventually be found and work.

GPU Support

GPU support on Windows with Nvidia GPUs is included out of the box in the .exe installer.

To add GPU support for source or pip installed version switch torch library to GPU version. For more info see https://pytorch.org/get-started/locally/ .

uv add --index https://download.pytorch.org/whl/cu128 torch==2.7.1+cu128 torchaudio==2.7.1+cu128
uv add --index https://pypi.ngc.nvidia.com nvidia-cublas-cu12==12.8.3.14 nvidia-cuda-cupti-cu12==12.8.57 nvidia-cuda-nvrtc-cu12==12.8.61 nvidia-cuda-runtime-cu12==12.8.57 nvidia-cudnn-cu12==9.7.1.26 nvidia-cufft-cu12==11.3.3.41 nvidia-curand-cu12==10.3.9.55 nvidia-cusolver-cu12==11.7.2.55 nvidia-cusparse-cu12==12.5.4.2 nvidia-cusparselt-cu12==0.6.3 nvidia-nvjitlink-cu12==12.8.61 nvidia-nvtx-cu12==12.8.55

To use Faster Whisper on GPU, install the following libraries:

• cuBLAS
• cuDNN

If you run into issues with FFmpeg, ensure ffmpeg dependencies are installed

pip3 uninstall ffmpeg ffmpeg-python  
pip3 install ffmpeg
pip3 install ffmpeg-python

For Whisper.cpp you will need to install Vulkan SDK. Follow the instructions here https://vulkan.lunarg.com/doc/sdk/latest/windows/getting_started.html

Run Buzz python -m buzz
