Description

Hello,
Here is the command I am using:

ffmpeg -i in.mp4 -c:v libx264 -crf 23 -c:a aac -strict experimental -q:a 100 -map_metadata 0 out.mp4

I read metadata of both input and output file after that with:

exiftool -a -G1 -s

and noticed that the following information is missing in the output file:

[QuickTime?] PlayMode? : SEQ_PLAY
[QuickTime?] GPSCoordinates : ## deg ##' ##.##" N, ##' ##.##" W
....
[Composite] GPSLatitude : ## deg ##' ##.##" N
[Composite] GPSLongitude : ## deg ##' ##.##" W
[Composite] GPSPosition : ## deg ##' ##.##" N, ##' ##.##" W

Real coordinates are not shown

Here is the output of:

ffmpeg -v 9 -loglevel 99 -i

Please test current FFmpeg git head and provide the command line you tested together with the complete, uncut console output to make this a valid ticket and provide a sample input file.

Looks like the latest version actually keeps the GPS coordinates however the Quicktime tag looks different.
Original:

[QuickTime]     GPSCoordinates                  : 50 deg 58' 4.08" N, 114 deg 4' 8.40" W

Output:

[QuickTime]     LocationInformation             : (none) Role=shooting Lat=50.96779 Lon=-114.06898 Alt=0.00 Body=earth Notes=

Is that normal?

Wanted to add that Mediainfo sees coordinates in the original file

©xyz                                     : +50.9678-114.0690/

but does not see them in the output file.

I sent the output file to the phone (Samsung Galaxy S6 Android 6.0.1) and it shows "No location" either.

Also, the altitude information that ffmpeg adds is incorrect. Looks like ffmpeg writes 0 value if the source file does have it.

I was able to copy moov/udta atom using https://www.bento4.com
mp4extract moov/udta input.mp4 temp.txt
mp4edit --insert moov:temp.txt output.mp4 output_gps.mp4

I tried to copy moov/udta/©xyz atom first but was not able to do that so I had to copy the entire [udta]

Hello,
I was wondering if this issue is going to be investigated.
To reproduce the issue you can

  1. Download this sample file: https://drive.google.com/file/d/0B5_iknSPeSNBM3JWeGFVS1kteDA/view?usp=sharing
  2. Convert it with
    -map_metadata 0
    
    option, for example
ffmpeg -i in.mp4 -c:v libx264 -crf 23 -c:a libfdk_aac -b:a 192k -map_metadata 0 out.mp4

and then

  1. Read metadata using the following tools:
ffmpeg -i FILE
mediainfo FILE
exiftool -a -G1 -s FILE

ffmpeg -i will show you that

com.android.version: 6.0.1

as well as

rotate          : 90

are missing

mediainfo will show you that

©xyz                                     : +##.####-###.####/
com.android.version                      : 6.0.1

is missing and replaced with:

Writing application                      : Lavf57.56.101

Also

Rotation                                 : 90°

is missing

ExifTool? will show you that

[QuickTime]     GPSCoordinates                  : ## deg ##' ##.##" N, ### deg #' ##.##" W 
[QuickTime]     ComAndroidVersion               : 6.0.1     

got replaced with:

[QuickTime]     HandlerType                     : Metadata
[QuickTime]     HandlerVendorID                 : Apple
[QuickTime]     Encoder                         : Lavf57.56.101
[QuickTime]     LocationInformation             : (none) Role=shooting Lat=##.##### Lon=-###.##### Alt=0.00 Body=earth Notes=

and

[QuickTime]     ComAndroidVersion               : 6.0.1  

is missing

as well as

[Composite]     Rotation                        : 90

got replaced with

[Composite]     Rotation                        : 0
