[OSM-dev] Videomapping / Mpeg4 with embedded GPS coordinates

[Florian Lohoff]

Hi,

i am owner of a Sony DSC HX5V - A Pocket Camera with integrated
GPS/Compass - I used to only use stills for mapping but today i 
tried recording a video while driving home.

It seems the Camera stores position information in the MPeg4 Transport
Stream which i found using "dvbsnoop":

        MPEG-DescriptorTag: 0 (0x00)  [= Reserved]

Did anyone try to decode this or even use it within the JOSM Videomapping
plugin?
