KML & GPX presets- invalid characters

Hello,

Firstly- thank you for gopro-telemetry- I’m only getting started, but it seems very useful

When using the gpx & kml presets, the output contains invalid characters- for example in the KML file, \n and \ characters

I can fix this by post-processing the output files, but how can I prevent this from occurring ?

thanks

Andrew

I see. Maybe the module is escaping those special characters under certain circumstances? It does not seem to happen on my end, but we can leave this open to keep an eye on it

Looking at the first screenshot, in addition to the \n you also have the escaped quotes \" It means you are using JSON.stringify to save the GPX data. However the GPX is in XML, not JSON, so it is incorrect to use the JSON.stringify.

While for full telemetry it looks like this (notice the fs.writeFileSync with JSON.stringify):

gpmfExtract(file)
    .then(extracted => {
        goproTelemetry(extracted, {}, telemetry => {
            fs.writeFileSync('full-telemetry.json', JSON.stringify(telemetry));
            console.log('Telemetry saved as JSON');
        });
    })
    .catch(error => console.error(error));

For the GPX it looks like this (no JSON.stringify):

gpmfExtract(file)
    .then(extracted => {
        goProTelemetry(extracted, {
            preset: 'gpx'
        }, telemetry => {
            fs.writeFileSync( 'gps-only.gpx', telemetry);
            console.log('GPS saved as GPX');
        });
    })
    .catch(error => console.error(error));
