I think I am making progress using GPSMid for audio mapping, but still having a few problems if anyone can help....
I have got GPSMid to record individual audio clips on demand, and produce a GPX waypoint when you record the clip. I can then export the GPX file and the audio files (amr format) to my PC. A little python script puts the required <link href=....> tags in the GPX file, and converts them to wav format using ffmpeg. When I import my GPX file into josm, it displays audio icons at the correct location, but when I click on them I get an error message saying "Error Playing Sound: <filename>". Where <filename> is the name of the file I clicked on (without full path). However, when you hit ok to accept the error dialog the file plays correctly... To make this work I had to include the full path to the .wav files in the <link> tags, otherwise it wouldn't play at all. A typical waypoint looks like: <wpt lat='54.698402' lon='-1.2252716'> <name>AudioMarker-GpsMid-2009-04-10_12-13-42</name> <com><time>2009-04-10T12:13:44Z</time></com> <link href="file:///home/disk2/OSM/OSM/Hartlepool_10apr2009/gpsmid-2009-04-10_12-13-42.wav">audio</link> </wpt> Can anyone suggest what I am doing wrong to generate this error please? Also, I would prefer to be able to use relative paths rather than absolute ones, so any pointers to what to change in josm would be appreciated. I am using the latest version of josm, from svn this evening. Regards Graham. 2009/3/28 Graham Jones (Physics) <[email protected]> > Tim, Dave, > Thank you for your help with this.
