A command line utility to overlay video with gps data
For example, given a video of a bike ride and telemetry data as tcx file, the script combines the two in a video that contains the original video with telemetry data overlay.
The original file is splitted in frames using ffmpeg, each frame and the synchronized trackpoint are processed by a php that produce an svg file.
The output svg file contains the original frame and the telemetry data ( gauges, elevation, etc ) based on trackpoint data. The svg file is rendered to a jpeg using a renderer ( convert, phantomjs, batik ) Finally, the output movie is done by merging the rendered jpeg
