Requires python >= 3.5.
Install ffmpeg:
brew install ffmpeg
Install python dependencies:
pip install -r requirements.txt
Optionally, install extra dev tools:
pip install ipython
pip install git+git://github.com/python/mypy.git
From the project root directory, run:
bin/run_mvz.py <youtube_id>
If this has never been run on the video before, this will take a long time (in
the neighborhood of 15 min per 1 min of video). In the future, the slow image
processing steps are cached in the ./cache directory. (You can bust the
cache and recompute everything by running bin/run_mvz.py --bust-cache <youtube_id>.)
Output ends up in the ./output directory. There will be one png for each
frame (which you can probably ignore), one mp4 file containing the cropped
output video, and a csv containing bounding boxes for each frame. The csv has
one line per 1/15s frame, with columns left, top, right, bottom coordinates.
(The coordinate system is such that upper left is (0, 0).)
