  • What is the difference between "location" and "location-eng" metadata of a MP4 file ?

    10 décembre 2020, par Weihang Jian

    I am trying to retrieve GPS information from media files using ffprobe, for example :

    


    $ ffprobe -v quiet -show_format sample.mp4
[FORMAT]
filename=sample.mp4
nb_streams=2
nb_programs=0
format_name=mov,mp4,m4a,3gp,3g2,mj2
format_long_name=QuickTime / MOV
start_time=0.000000
duration=4.293000
size=11888152
bit_rate=22153556
probe_score=100
TAG:major_brand=mp42
TAG:minor_version=0
TAG:compatible_brands=isommp42
TAG:creation_time=2020-09-20T11:33:49.000000Z
TAG:location=+25.0731+121.3663/
TAG:location-eng=+25.0731+121.3663/
TAG:com.android.version=10
TAG:com.android.manufacturer=Google
TAG:com.android.model=Pixel
[/FORMAT]


    


    We can see that there are 2 tags that look like ISO6709 representations, location and location-eng.

    


    And here are my questions :

    


      

    1. What is the difference between location and location-eng ? It looks like they are always the same. Why do we need 2 different keys with same the value ?

      2. 


    2. Are location and location-eng really in ISO6709 representations ? Is there any specification or standard I can refer to ?

      3. 


    


    I would really appreciate your help.
