Reading 3GPP files

Introduction

Unfortunately due to an Android SDK limitation, OSMTracker can only record audio file in 3GP format. Here is how to play 3GP files under different OSes.

Windows

• Install ffmpeg-tryouts
• Install Haali Media Splitter
  • Be sure to enable MP4 support when installing HMS.

After that you can play 3GP files with your preferred media player.

Mac OS X

QuickTime has native support for 3GP files.

Linux

As suggested by misc2006, the following script can be used to convert 3GP into WAV and update the GPX file with new file names (assuming you have ffmpeg installed):

#!/bin/bash
for file in *.3gpp
do
  ffmpeg -y -i $file -f wav "$file.wav"
  touch "$file.wav" -r $file
done

rename 's/\.3gpp//' *.wav

sed 's/\.3gpp<\/link>/.wav<\/link>/' *.gpx > ready-to-map.gpx
