• how can I play ffmpeg codecs not supported by MedicaPlayer ? [closed]

  1er septembre 2011, par Jun

  Currently, I'm using MediaPlayer to play mp4, 3gp videos and it works as it should do but now I need to play ffmpeg codecs too.

  In this case, do I have to develop my video player or is there any players from 3rd parties ?

  Thanks in advance.

• 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.

• Using -itsoffset with AAC Tracks in MP4 : What Actually Happens ? [closed]

  10 avril, par user27607034

  If the frame duration of an AAC file is around 21 milliseconds, does the itsoffset value in the following command actually get applied ? And even if it does, will players like QuickTime or a smart TV actually respect it ?

  


  ffmpeg -itsoffset 0.009 -i input.mp4 \
  -i input.mp4 \
  -map 1:v:0 \ // hevc
  -map 0:a:0 \ // aac
  -c copy \
  output.mp4
