  • ffmpeg : How to preserve input metadata when copying / resizing [duplicate]

    16 mars 2021, par Ivan

    I would like that the output file has the same metadata as the input

    


    I have two case :

    


      

    1. with images

      2. 


    


    find . -name "*.jpg"|while read fname; do
  ffmpeg -y -i "$fname" -map_metadata 0 -vf scale=1024:-1 ./compressed/"$fname"
done


    


      

    1. with video

      2. 


    


    find . -name "*.mp4"|while read fname; do
    ffmpeg -y  -i "$fname" -map_metadata 0 -vf scale=1024:-2,setsar=1:1 -c:v libx264 -c:a copy ./compressed/"$fname"
done


    


    In both cases, meta data is lost (data of edited set current date, can I move "edited date" from original file)

    


    Parameter -map_metadata 0 does not help

    


    Tell me please, what should I fix ?

  • How to copy ffprobe dumped metadata to a converted video

    23 mai 2020, par Quer

    I hope you're all doing safe ! I'm using windows 10 and have lots of home videos, some of them are on .AVI format. I just discovered google photos don't backup .AVI videos, I tried converting it with GUI converters (FormatFactory, Wondershare, HandBrake) but when I tried to back it up, it wasn't preserving the metadata of my newly converted videos.

    



    I tried further research on this matter and I stumble upon ffmpeg (w/c the GUIs were using). I successfully converted .MOV while preserving metadata using :

    



    ffmpeg -i in.MOV -b:v 73000k -c:v libx264 -c:a aac -strict -2 -map_metadata 0 out.mp4


    



    but when I tried converting .AVI videos, with the command above, it doesn't retain the original metadata for the out.mp4.

    



    I tried another approach and I found out a method of dumping the metadata on a .txt then restoring it on the out.mp4.

    



    ffprobe -v error -show_format -show_streams DSCF0421.AVI > output.txt 2>&1


    



    The command above does save it on the output.txt

    It doesn't successfully restore the metadata of the source .AVI

    



    BTW, I don't intend to shrink the size of the video I just need to retain its created date and some miscellaneous.

    



    Thank you in advance for those who will answer !

    


  • Compile Shotdetect on CentOS 7

    14 septembre 2015, par BitLegacy01

    I’m migrating a service from a Debian server to a CentOS 7 one.

    The service needs the Shotdetect command (github , official site).

    I could not make it work on CentOS though I followed all steps :

    1. Compile ffmpeg compilation guide

      # ffmpeg
      
ffmpeg version git-2015-08-21-7a806c6 Copyright (c) 2000-2015 the FFmpeg developers

Hyper fast Audio and Video encoder
      
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

      1. Install needed packages

        # yum install gd-devel libxml2-devel libxslt-devel clang libvpx libvorbis

      2. Add pthread in the CMakeList file, in TARGET_LINK_LIBRARIES, because it throws an lpthread missing in linker error

      3. Compile Shotdetect

        # FFMPEG_DIR="/root/ffmpeg_build"  ./compile.sh cmd

    the built binary will be in the built directory, you can move there and execute

    make install

    to make the binary system wide.
