Discuss on GitHub Discussions

• Overlaying exciting graphics onto GoPro videos with super-exact synchronization
• Create videos from any GPX or FIT file - no GoPro required
• Support multiple resolutions, most GoPro models, normal, timelapse & timewarp modes
• Support GPUs to create movies at up to 17x realtime
• Convert GoPro movie metadata to GPX or CSV files
• Cut sections from GoPro movies (including metadata)
• Linux, Mac, Windows!

Examples

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

Map Styles

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

Requirements

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

Installation

See below for Windows instructions.

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 docker

The docker image is a new thing and still a bit experimental... please file an issue if you find any problems.

The docker image contains all you need to get started, and uses a volume /work/, which we suggest you map to the current directory which can contain your GoPro files. Note that the docker version doesn't support nvidia GPU extensions.

The most recent version on docker is:

docker run -it -v "$(pwd):/work" overlaydash/gopro-dashboard-overlay:<version> <program> [args...]

e.g.

docker run -it -v "$(pwd):/work" overlaydash/gopro-dashboard-overlay:0.92.0 gopro-dashboard.py GH010122.MP4 render/docker.MP4

Files created by the program will be created with the same uid that owns the mapped directory.

You can use the --cache-dir and --config-dir command line arguments to configure where the cache and config dirs are, thereby making it easier to use persistent mapped volumes.

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

Installation on Windows

I don't know very much about windows, so corrections to these instructions are welcomed.

Installing Python

Get the Windows installer from https://www.python.org/downloads/windows/ - Install it. Suggest "add to PATH".

Installation

python3 -mvenv venv
venv/Scripts/pip install gopro-overlay

You'll also need to install ffmpeg, if you don't have it already. You can download this from https://www.gyan.dev/ffmpeg/builds/ - The "essential version" is OK. Unzip this somewhere. The default might be something like: C:\Users\james\Downloads\ffmpeg-6.0-essentials_build

Windows might not have Roboto Font, so start with a standard windows font - on my Windows 11 box, Trebuchet is installed.

In PowerShell...

Set-ExecutionPolicy Unrestricted -Scope Process
.\venv\Scripts\activate.ps1
python .\venv\Scripts\gopro-dashboard.py --font trebuc.ttf --ffmpeg C:\Users\james\Downloads\ffmpeg-6.0-essentials_build\ffmpeg-6.0-essentials_build\bin input.mp4 output.mp4

Configuration files will go into %UserProfile%\.gopro-graphics

On my (pretty quick) Windows 11 Box, I get 35 fps (=3.5x realtime) on 2.7k with CPU only, and about the same with GPU.

I did get two errors running with GPU:

• decoder->cvdl->cuvidCreateDecoder(&decoder->decoder, params) failed -> CUDA_ERROR_INVALID_VALUE: invalid argument
  • This was fixed by following insttructions in docs/bin/README.md (adding -threads parameter)
• The minimum required Nvidia driver for nvenc is 522.25 or newer
  • Needed to upgrade nvidia driver.

--double-buffer DOES NOT WORK on Windows - shame - I don't really know how to implement this on Windows.

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

Experimental

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 docs/bin/PERFORMANCE_GUIDE.md

Please also see PERFORMANCE.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.

Known Bugs / Issues

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

Latest Changes

If you find any issues with new releases, please discuss in GitHub Discussions

• 0.115.0 [Fix] Previous smoothing had some issues - hopefully sorted. Fixed possible issue with ffmpeg exiting before writing MOOV - sometimes could result in unplayable MP4 files.
• 0.114.0 [Enhancement] Huge Improvement to usability of speed gauges! - Speed was not being smoothed. Now a kalman filter is applied to speed, giving a much better result. See below for before and after. This stops the speed gauges flickering between values.
• [Breaking/Minor] Removed the decimal values for altitude & gradient in the default layouts - they were distracting as they changed too much.

• 0.113.0 [Enhancement] Add arc gauge - See Arc Gauge Docs for examples
• 0.112.0 [Enhancement] Show loading speed of gopro data.
• 0.111.0 [Fix] Simple Fix for #157 - timeout when reading large data files. Thanks to @rpoxo for raising.
• 0.110.0 [Fix] Hopefully make the 'pace' units more robust. New metric format "pace".
• 0.109.0 [Feature] Support for new GPS9 data type - should give more accurate GPS. Supported on Hero11+
• 0.108.0 [Fix] GPX/GoPro overlay date checking had been broken for a while. Thanks (very much) to @IbnGit for raising
• 0.107.0 [Feature] New units! - "spm" - steps per minute, and "pace" - see metrics docs for full explanation Thanks @SlippyJimmy
• 0.106.0 [Feature] New map style "cyclosm" - see: https://www.cyclosm.org/ - An OpenStreetmap for cycling - See map examples for more
• 0.105.0 [Behaviour Change] Fix #150 cairo circuit map aspect raio is wrong. Thanks @yuanduopeng for raising.
• 0.104.0 [Fix] Honour cmdline arg --show-ffmpeg
