• How to iterate through subfolders and merge all parted video files [closed]

  1er janvier 2024, par Rave

  I'm trying to loop through several sub-folders to check if there are separate videos in these sub-folders. If this is the case, FFMPEG would have to assemble them automatically. The videos are named as follows :

  


  Movie1
  Movie1/Movie1-part1.mpg
  Movie1/Movie1-part2.mpg
Movie2
  Movie2/Movie2-part1.mkv
  Movie2/Movie2-part2.mkv


  


  The aim would be to automate this task using a bash script. I don't know if I should use MKVToolnix or FFMPEG for this and how I should begin to code this.

  


  Solution :

  


  Thanks to the comment and help of Socowi I have tried to create my own script that works. I hope that this solution might be useful to others.

  


  for directory in */; do
    count=0
    echo "$directory"
    for file in "$directory"*; do
        file=${file//$directory/}
        if [[ $file == *-part* ]]; then
            echo "file '$file'" >> "$directory"mylist.txt;
            count=$((count + 1))
        fi
    done

    if (($count != 0)); then
        for name in "$directory"*part01*; do
            name=${name//-part01.*/.mkv};
        done

        echo $name
        if ffmpeg -loglevel warning -f concat -safe 0 -i "$directory"mylist.txt -c copy -safe 0 "$name" ; then
            echo "Success"
            rm "$directory"mylist.txt
        else 
            echo "Failed"
            rm "$directory"mylist.txt
        fi
    else
        echo "No part files in $directory"
    fi 
done


  


• How can I merge video files (has audio stream) and audio file (as a bgm) using ffmpeg ?

  18 février 2016, par ntaku

  I want to merge video files (has audio stream) and audio file (as a background music) using ffmpeg command.

  • video1.mp4 (has video and audio stream)
  • video2.mp4 (has video and audio stream)
  • audio.mp3 (audio stream only)

  These are sample files.
  https://www.dropbox.com/sh/ejmjmwk9j0nsk7z/AABqkYd7Zf9izRn785Vd92Wra?dl=0

  I tried these command and more but all didn’t work.

  ffmpeg -i video1.mp4 -i video2.mp4 -i audio.mp3 -filter_complex "concat=n=2:v=1:a=1" output.mp4
  
  
  
  ffmpeg -i video1.mp4 -i video2.mp4 -i audio.mp3 -map 0 -map 1 -map 2 output.mp4

  How can I create the video like this structure in one command ?

  video channle1 | video1 video stream | video2 video stream |
  audio channle1 | video1 audio stream | video2 audio stream |
  audio channel2 |                   audio                   |
