Usage

In order to use this library in a project, the executable program must have access to the FFmpeg DLLs. The code below assumes that your top-level project contains a folder named FFmpeg, which includes the DLLs. Each of the DLL's must have Build Action set to Content and Copy to Output Directory set to Copy if newer.

using FFmpeg.AutoGen;
using FrozenNorth.Gpx;
using FrozenNorth.Gpmf;

// get the file names
string videoFileName = ...
string gpxFileName = Path.ChangeExtension(videoFileName, "gpx");

// configure FFMPEG
Assembly assembly = Assembly.GetExecutingAssembly();
ffmpeg.RootPath = Path.Combine(Path.GetDirectoryName(assembly.Location), "FFmpeg");

// get the GPMF items
GpmfItems gpmfItems = Gpmf.LoadMP4(videoFileName);

// get the GPS items as a GPX object
Gpx gpx = Gpmf.GetGpx(gpmfItems);

// save the GPX object to a file
if (gpx.Tracks.Count > 0)
{
    Version version = assembly.GetName().Version;
    gpx.Creator = "ExtractGPX " + version.ToString((version.Revision != 0) ? 3 : 2);
    gpx.Tracks[0].Name = Path.GetFileName(videoFileName);
    GpxWriter.Save(gpx, gpxFileName);
}
else
{
    Console.WriteLine("ERROR: No GPS data found in MP4 file.");
}
