gokart

A golang library allowing to exctract meta data from GoPro video.

WARNING This is a Work In Progress, code should be clean-up, documented, tested to be production ready.

Tests

Some tests are available, create a data folder and download video example: 20240914T1112_Ancenis.mp4

mv ~/Downloads/20240914T1112_Ancenis.mp4 data
go test

Examples

DrawLap

An example is available to draw best lap trajectory from a video on an aerial image. You will need the aerial image corresponding to the track in the video, for example: Ancenis.png

mv ~/Downloads/Ancenis.png data
cd cmd/drawlap
go build
./drawlap -in ../../data/20240914T1112_Ancenis.mp4

It will generate an image named best_lap.png with trajectory in color where red means deceleration and green means acceleration.

AI4INDUSTRY

An other example show how to extract GPS information per image, allowing to export each frame with meta data in filename.

• Compile

cd cmd/ai4industry
go build

• To see all frames info for default Ancenis video

./ai4industry

• To export 20 frames from 7366 to 7385 from Ancenis video:

./ai4industry -start 7366 -stop 7385 -export
