• FFMPEG process Killed and raises returncode 137 when executed through python3 subprocess.Popen but runs fine from the command line

  22 novembre 2017, par Stuart Clarke

  I’m not sure if this is the best way to go about this, but I have another question here which I don’t think was asked very well (or more to the point I realised the actual problem and have a simpler way of asking for help). If you can answer this question you’ll have the answer to the other.

  I’m using python 3.5.2 and ffmpeg 3.3.4-2 and have this function to run my ffmpeg commands :

  def ffmpegPro(args):
  
      err = None
  
      for i, arg in enumerate(args):
  
          if(" " in arg or "(" in arg or "[" in arg):
  
              args[i] = "\"" + arg + "\""
  
      command = [
  
          ffmpegcmd, '-y',
  
          '-loglevel', loglevel
  
      ] + args
  
      commandStr = " ".join(command)
  
      ffmpeg = subprocess.Popen(commandStr, stdin=subprocess.PIPE, stderr=subprocess.PIPE, stdout=subprocess.PIPE, universal_newlines=True, shell=True)
  
      out, err = ffmpeg.communicate()
  
      if ffmpeg.returncode != 0:
  
          print(commandStr + "\n" + "ERROR CODE: " + str(ffmpeg.returncode))
  
          raise Exception(err)

  When I pass the following args the returncode is 137 and the process is Killed. This only occurs when executed in python, when I run the same command at the command line it executes as expected.

  ['-i', '/var/www/temp/film.mp4', '-vf', 'scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:x=(1920-iw)/2:y=(1080-ih)/2:color=black', '/var/www/temp/videoHD.mp4']

  The resulting command is :

  ffmpeg -y -loglevel verbose -i /var/www/temp/film.mp4 -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:x=(1920-iw)/2:y=(1080-ih)/2:color=black" /var/www/temp/videoHD.mp4

  When executed through python :

  ERROR CODE: 137

  and the output video is fine.

  Why would this process be killed by python ?

• ffmpeg crashes on crossfades between 3 clips if 2 clips coming from same input file [closed]

  14 avril 2020, par Erik

  I observed that ffmpeg 4.2.2 (macOS) crashes in particular cases of crossfades between clips, if one clip comes from file 1.dv, and two clips are cut out of file 2.dv, as shown below :

  



  ffmpeg -f lavfi -i color=black:size=720x576:duration=11:rate=25 -i 1.dv -i 2.dv -filter_complex "\
    [1:v]trim=5:10,setpts=expr=PTS-STARTPTS,yadif,fade=alpha=1:d=2:st=3:type=out,setpts=expr=PTS-STARTPTS,fifo[s5];\
    [2:v]split=2[s7][s8];\
    [s7]trim=5:10,setpts=expr=PTS-STARTPTS,yadif,fade=alpha=1:d=2:type=in,fade=alpha=1:d=2:st=6:type=out,setpts=expr=PTS-STARTPTS+(3/TB),fifo[s15];\
    [s8]trim=12:17,setpts=expr=PTS-STARTPTS,yadif,fade=alpha=1:d=2:type=in,setpts=expr=PTS-STARTPTS+(6/TB),fifo[s22];\
    [0:v][s5]overlay=eof_action=repeat[s6];\
    [s6][s15]overlay=eof_action=repeat[s16];\
    [s16][s22]overlay=eof_action=repeat[s24];\
    [1:a]atrim=5:10,asetpts=expr=PTS-STARTPTS[s26];\
    [2:a]asplit=2[s27][s28];\
    [s27]atrim=5:10,asetpts=expr=PTS-STARTPTS[s30];\
    [s28]atrim=12:17,asetpts=expr=PTS-STARTPTS[s33];\
    [s26][s30]acrossfade=d=2[s31];\
    [s31][s33]acrossfade=d=2[s36]" \
     -map "[s24]" -map "[s36]" -ab 128k -acodec aac -crf 23 -movflags faststart -preset medium -tune film -vcodec libx264 -aspect 1024:576 out.mp4 -y


  



  The order makes a difference : if the two clips from 2.dv are used first and then the clip from 1.dv is appended, everything works fine. Also, if all clips are coming from different files.

  



  ffmpeg 3.4.6 (ubuntu 18.04) shows no issues in any case.

  



  A self-compiled ffmpeg version N-97322-gb1699f4 (commit 2020-04-13) works with short clips as above, but crashes if one of the two clips taken from 2.dv is getting longer. In my tests 1500 frames (64 sec) is OK, 1700 (68 sec) leads to a segmentation fault. That is, if you replace in the command line above :

  



  

  • [s7]trim=5:10... -> [s7]trim=0:68 and accordingly

  


  • [s27]atrim=5:10... -> [s27]atrim=0:68

  


  



  Interestingly, the length of the clip taken from 1.dv does not play a role.

  



  The ffmpeg output shows about 20 times :

  



  frame=    0 fps=0.0 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x  


  



  before it continues (seg fault case) :

  



  frame=    4 fps=0.3 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x    
frame=   24 fps=1.6 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x    
frame=   25 fps=1.5 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x    
frame=   34 fps=1.9 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x

frame=   39 fps=2.1 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x    
frame=   40 fps=2.0 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x

frame=   40 fps=1.9 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x    



  



  success case :

  



  frame=    5 fps=0.4 q=0.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x    
frame=   42 fps=3.2 q=28.0 size=       0kB time=00:00:00.00 bitrate=N/A speed=   0x    
frame=   53 fps=3.9 q=28.0 size=       0kB time=00:00:00.36 bitrate=   2.9kbits/s speed=0.0264x    
frame=   65 fps=4.6 q=28.0 size=       0kB time=00:00:00.84 bitrate=   1.2kbits/s speed=0.0594x 
...   


  



  Slightly older versions included in the newest MacOS builds from zeranoe.com (git-2020-04-13-59e3a9a) and evermeet.cx (N-97308-g14dd0a9057-tessus, from 2020-04-12) are working nicely - also on my production cases (longer clips).

  



  Any feedback would be appreciated !
