Installation with poetry

First, clone the repository

git clone https://github.com/LoonanChauvette/video-vocal-RT.git

Then, inside the package folder, install the dependencies with poetry

cd video-vocal-RT
poetry install

Poetry creates a virtual environment, you should be able to activate it using :

poetry shell

Then you can run the script using :

poetry run python video_vocal_rt/main.py

How-to

Place your video files in the VIDEO_FILES directory (only supports .avi files for now). For the moment, you need to go inside video_vocal_rt/main.py before running the experiement. There you should make sure to set the audio recording duration in seconds (default is 6 seconds, but should be the typical length of your videos). You also need to set the PARTICIPANT_ID to the desired value.

You can also set fixation parameters with FIXATION_DUR for the duration (default is 1000 ms). You can provide change the file "fixation.png" to customize the fixation. By default, there is a whiteout period after the video, its duration can be changed with WHITEN_DUR (default is 1000 ms).
