• FFmpeg / python - command works when run from shell but fails when run from python

  4 avril 2019, par artembus

  I have a python script which should run an ffmpeg command with this function :

  def transcode(in_path, out_path):
  
      cmd = ["ffmpeg", "-y", "-i", in_path, '-vf smartblur=lr=1']
  
      cmd += ["-an", out_path]
  
      print("Running:", " ".join(cmd))
  
      subprocess.run(cmd, stdout=cmdout, stderr=cmdout)

  When I run the python script it fails with this ffmpeg error :

  Running: ffmpeg -y -i raid/orig/scenes/train/5786088.mp4 -vf smartblur=lr=1 -an raid/4K/scenes/train/5786088.mp4

  You can see the command it tries to execute in the first line, when I run it in the command line it works fine. When I run the command in the shell it outputs the same version and parameters of the ffmpeg as written in the error above.

  I feel like I missed something simple yet crucial, anyone can point me to the right direction ?

• How create dynamic folder with input structure in shell script when using ffmpeg ?

  23 octobre 2020, par Sathish Kumar

  i have created this shell script to encode videos using ffmpeg. i need to maintain the folder structure of input and output folder automatically when i run this script.

  


  Problem : As of now, it moves all videos to root of destination directory. it need to create subfolder and output file should save in it.

  


  Input folder :

  


  Folder1
--sub_folder
---video1.mkv
---video2.ts
---video3.mp4
Folder2
---cat.mkv
---mouse.ts
---train.mp4



  


  Expected Output folder :

  


  Folder1
--sub_folder
---video1.mp4
---video2.mp4
---video3.mp4
Folder2
---cat.mp4
---mouse.mp4
---train.mp4


  


  Code :

  


  srcDir=$1
destDir=$2

for filename in $(find "$srcDir" -type f); do

        basePath=${filename%.*}
        baseName=${basePath##*/}

        audioformat=$(ffprobe -loglevel error -select_streams a:0 -show_entries stream=codec_name -of default=nw=1:nk=1 "$filename")
        videoformat=$(ffprobe -loglevel error -select_streams v:0 -show_entries stream=codec_name -of default=nw=1:nk=1 "$filename")

        if [ "$audioformat" == "aac" ] &&  [ "$videoformat" == "h264" ] ; then
                echo $filename
                echo $audioformat + $videoformat
                ffmpeg -i "$filename" -y -c:v copy -c:a copy "$destDir"/"$baseName.mp4" -hide_banner -loglevel warning 
        elif [ "$audioformat" == "aac" ] &&  [ "$videoformat" != "h264" ] ; then
                echo $filename
                echo $audioformat + $videoformat
                ffmpeg -i "$filename" -y -c:v libx264 -c:a copy "$destDir"/"$baseName.mp4" -hide_banner -loglevel warning 
        elif [ "$audioformat" != "aac" ] &&  [ "$videoformat" == "h264" ] ; then
                echo $filename
                echo $audioformat + $videoformat
                ffmpeg -i "$filename" -y -c:v copy -c:a aac "$destDir"/"$baseName.mp4" -hide_banner -loglevel warning 
        else
                echo $filename
                echo $audioformat + $videoformat
                ffmpeg -i "$filename" -y -c:v libx264 -c:a aac "$destDir"/"$baseName.mp4" -hide_banner -loglevel warning 
        fi
