Introduction Video

Examples

An Example of 'overlay only' mode, which generates movies from GPX files

Example from examples/layout

Map Styles

Almost 30 different map styles are supported! - See map styles for more

Example

Requirements

Python3.10 (development is done on Python3.11)
ffmpeg (you'll need the ffmpeg program installed)
libraqm (needed by Pillow)

Installation

For Windows, please see docs docs/windows.md

For Docker, please see docs at docs/docker.md

Install locally using pip, or use the provided Docker image

Optional: Some widgets require the cairo library - which must be installed separately.

Installing and running with pip

python -m venv venv
venv/bin/pip install gopro-overlay

The Roboto font needs to be installed on your system. You could install it with one of the following commands maybe.

pacman -S ttf-roboto
apt install truetype-roboto
apt install fonts-roboto

(Optional) Installing pycairo

Optionally, install pycairo

venv/bin/pip install pycairo==1.23.0

You might need to install some system libraries - This is what the pycairo docs suggest:

Ubuntu/Debian: sudo apt install libcairo2-dev pkg-config python3-dev

macOS/Homebrew: brew install cairo pkg-config

Example

For full instructions on all command lines see docs/bin

venv/bin/gopro-dashboard.py --gpx ~/Downloads/Morning_Ride.gpx --privacy 52.000,-0.40000,0.50 ~/gopro/GH020073.MP4 GH020073-dashboard.MP4

Caveats

The GPS track in Hero 9 seems to be very poor. If you supply a GPX file from a Garmin or whatever, the program will use this instead for the GPS. Hero 11 GPS is much improved.

Privacy allows you to set a privacy zone. Various widgets will not draw points within that zone.

The data recorded in the GoPro video will uses GPS time, which (broadly) is UTC. The renderer will use your local timezone to interpret this, and use the local timezone. This may produce strange results if you go on holiday somewhere, but then render the files when you get back home! On linux you can use the TZ variable to change the timezone that's used.

Writeups

There's a great writeup of how to use the software to make an overlay from a GPX file at https://blog.cubieserver.de/2022/creating-gpx-overlay-videos-on-linux/ (Nov 2022)

Format of the Dashboard Configuration file

Several dashboards are built-in to the software, but the dashboard layout is highly configurable, controlled by an XML file.

For more information on the (extensive) configurability of the layout please see docs/xml and lots of examples

FFMPEG Control & GPUs

FFMPEG has a lot of options! This program comes with some mostly sensible defaults, but to use GPUs and control the output much more carefully, including framerates and bitrates, you can use a JSON file containing a number of 'profiles' and select the profile you want when running the program.

For more details on how to select these, and an example of Nvidia GPU, please see the guide in docs/bin#ffmpeg-profiles

Please also see other docs PERFORMANCE.md and docs/bin/PERFORMANCE_GUIDE.md

Converting to GPX files

venv/bin/gopro-to-gpx.py <input-file> [output-file]

Joining a sequence of MP4 files together

Use the gopro-join.py command. Given a single file from the sequence, it will find and join together all the files. If you have any problems with this, please do raise an issue - I don't have that much test data.

The joined file almost certainly won't work in the GoPro tools! - But it should work with gopro-dashboard.py - I will look into the additional technical stuff required to make it work in the GoPro tools.

This will require a lot of disk space!

venv/bin/gopro-join.py /media/sdcard/DCIM/100GOPRO/GH030170.MP4 /data/gopro/nice-ride.MP4

Cutting a section from a GoPro file

You can cut a section of the gopro file, with metadata.

Help Wanted

Adding additional graphics widgets, ideally using cairo.
Validation / Improvement of smoothing - e.g. Kalman Filters
Suggestions for handling acceleration and orientation data, this is parsed, but display options are few.

Work In Progress

Adding min/max/moving averages to metrics

Known Bugs / Issues

Only tested on a GoPro Hero 9/11, that's all I have. Sample files for other devices are welcomed.
