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]
descriptor_length: 177 (0xb1)
----> ERROR: unimplemented descriptor (mpeg context), Report!

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