• Convert .MOD video files to .mp4 but maintain original file date

  27 février 2016, par Barryman9000

  Windows 10,
  ffmpeg

  I’m very new to ffmpeg so I can’t figure this out. I’m trying to use a command to copy then convert all .MOD video files in a directory to .mp4 files and keep the original date that the .MOD file was created. I don’t understand how to map the current file in the loop to the map_metadata option. This command works but doesn’t maintain the metadata (taken from this post)

  FOR /F "tokens=*" %G IN ('dir /b *.MOD') DO ffmpeg -i "%G" -acodec copy "%~nG.mp4"

  I’ve tried including the map in the above command but get various errors, mostly "invalid input file index : 1". The commands below will copy and convert but the new .mp4 files don’t have the original file date so I must be using map_metadata incorrectly :

  FOR /F "tokens=*" %G IN ('dir /b *.MOD') DO ffmpeg -i "%G" -acodec copy -map_metadata 0 "%~nG.mp4"
  
  
  
  FOR /F "tokens=*" %G IN ('dir /b *.MOD') DO ffmpeg -i "%G" -map_metadata 0 -acodec copy "%~nG.mp4"

  Any suggestions ? Thanks

  UPDATE

  I got this with Powershell ! (thanks to this post)

  $oldvids = Get-ChildItem *.MOD -Recurse
  
  foreach ($oldvid in $oldvids) {
  
      $newvid = [io.path]::ChangeExtension($oldvid.LastWriteTime.toString("MMMddyyyy_HHmmss"), '.mp4')
  
      ffmpeg.exe -i $oldvid.FullName -c:v libx264 -crf 18 -c:a aac -q:a 100 $newvid
  
  }

  input : MOV01E.MOD (Created date 4/1/2012 10:10 AM)

  output : Apr012012_101005.mp4

  ANOTHER UPDATE

  The above command kind of works but I just realized all of the files are output to the root directory. I changed the command a bit but I’m not sure what’s going on :

  Get-ChildItem *.MOD -recurse | % {
  
      $newvid =  [io.path]::ChangeExtension($_.LastWriteTime.toString("MMMddyyyy_HHmmss"), '.mp4')
  
      ffmpeg.exe -i $_.FullName -c:v libx264 -crf 50 -c:a aac -q:a 100 $newvid
  
  }

  How to auto delete files every 3 hours in a directory var/www/html/stream that file name start with 1080 or 720 or 480 or 360 ?

  Iam doing this because once ffmpeg stops for any reason, it still keeps the old file and folder size is huge. Thanks for your help

• 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                   |
