    I have integrated FFmpeg libraries to my project.

    Kindly Pour your knowledge.

  • ffmpeg does not copy custom metadata

    20 juin 2015, par e110c0

    I’m trying to fix some videos made with an iDevice. The videos have a rotation in the metadata which is only understood by Apple and its software but noone else. Fixing this is quite simple, but I also would like to keep the other metadata in the files like the geolocation.

    I tried a couple of versions, all with the same result, e.g. :

    ffmpeg -i input.mov -vf vflip,hflip -map_metadata 0 -metadata:s:v:0 rotate=0  -acodec copy output.mp4

    This should work, it already gives the correct preview of metadata :

    I also tried to add the one tag I’m interested in by hand with

    -metadata:g location=+48.2683+007.7205+172.710/

    with no change in the result.

    Output as .mov doesn’t change anything, neither.

    Is there any trick to add non-standard metadata ? How do I get the location back in there ?

    Thanks in advance to anyone who can give some insight on this.

  • correctly escaping text in drawtext filter
