• DP2340 GPS track extraction (exiftool) (done)
• Auto-detect stopped segments (done)
• Splice video using data generated from previous section (done)

Reqs and Dependencies

The following should be in your path.

• Exiftool
• FFMPEG

Instructions

• Run python process1.py -V <video> [-O <gpx_output_file> -S <splice_naming_scheme>] to process using stops by speed.
• Run python process2.py -V <video> [-O <gpx_output_file> -S <splice_naming_scheme>] to process using stops by readings.
• To process videos in a folder use python script.py [-M] -D <folder>.
  • Use -M to use stops by readings to process the videos. Uses stops by speed by default.
• To process a concatenated video and create a concatenated GPX file, use python process.py [-D <folder> -O <output_concatenated_vid> -OG <output_concatenated_gpx_file> -S <sensitivity> -N <noise>].
  • Creates several folders for each method (stop, speed currently) and places the spliced videos in them.
  • Using -S or --sensitivity determines if stops with duration less than it will be included. Defaults to 2s.
  • Using -N or --noise determines the noise used with ffmpeg's freezedetect. Defaults to 35.
