c++ - Parsing *.nmea file with QNmeaPositionInfoSource class returns timeout. - Stack Overflow  

Also, you can subclass QGeoPositionInfoSource to take in any type of file. For example, we did this with GPX files for an example app - dynamic-situational-awareness-qt/GPXLocationSimulator.h at master · Esri/dynamic-situational-awarene...
