• FFMPEG Batch Copy Metadata from "Folder1File1.mp3" to "Folder2File1.mp3" in different folders

  27 février 2020, par Vektorz

  I have two separate files in separate folders with the same name and I would like to transfer the metadata from the file in "folder1" to "folder2".
  Then I would like to add a whole bunch of files fitting this same format and batch transfer all of the metadata information.

  From a stack exchange thread I’ve tried :

  "The following script will loop through the the files in one directory, find corresponding files in a second directory and then combine these two files into a third output directory
  
  
  
  dir1=FIRST DIRECTORY
  
  dir2=SECOND DIRECTORY
  
  output=OUTPUT DIRECTORY
  
  for file in $(ls $dir1); do
  
    ffmpeg -i "$dir1/$file" -i "$dir2/$file" -map 1 -c copy \
  
     # copies all global metadata from in0.mkv to out.mkv  
  
     -map_metadata 0 \
  
     # copies video stream metadata from in0.mkv to out.mkv
  
     -map_metadata:s:v 0:s:v \
  
     # copies audio stream metadata from in0.mkv to out.mkv
  
     -map_metadata:s:a 0:s:a \
  
     "$outdir/$file"
  
  done"

  But for the life of me I cannot get this to work properly and it is a bit overkill. He continues on saying :

  If you want to make something reuseable you could put this in a script with the following header (remove the assignment for dir1, dir2 and output in the script above). And then call it as script.sh dir1 dir2 outdir
  
  
  
  #!/bin/bash
  
  set -x errexit # exit immediately on error
  
  dir1="$1"
  
  dir2="$2"
  
  output="$3"

  And I am totally lost. Can someone please help me to get this to work and walk me through it a bit easier as I’m fairly inexperienced with code/FFMPEG.

  Thank you.

• ffpyplayer with libx264 error : cannot locate symbol "avio_seek" referenced by "player.so"

  2 décembre 2016, par Gerasimov Mikhail

  Kivy’s ffpyplayer 3.2 can be built with python-for-android’s old toolchain recipe. I also want ffpyplayer to open more video formats so I try to add libx264 for ffmpeg2 recipe.

  I created separate recipe for libx264, here’s how I build lib :

  try ./configure \
  
    --cross-prefix=arm-linux-androideabi- \
  
    --sysroot="$NDKPLATFORM" \
  
    --host=arm-linux \
  
    --enable-pic \
  
    --disable-asm \
  
    --disable-cli \
  
    --disable-opencl \
  
    --enable-shared \
  
    --prefix=$BUILD_x264

  Here’s main part where I add libx264 to ffmpeg2 :

  debug "Activate flags for x264 / ffmpeg2"
  
  x264_CFLAGS="-I$BUILD_x264/include/"
  
  x264_LDFLAGS="-L$BUILD_x264/lib/ -Wl,-soname,libx264.so"

  Everything compiles fine, but I’m getting error when trying to use ffpyplayer on Android device :

  ffpyplayer - ImportError : dlopen failed : cannot locate symbol
  "avio_seek" referenced by "player.so"

  Any idea what can it be ?

  I have no knowledges in compiling libs so I would be grateful if you suggest me way where to go to find reason of this error.
