• Trimming videos using FFMPEG + Python : Invalid Argument

  26 juin 2019, par user2588534

  I am looking to use a short Python script to automate some video cutting for me based on a .txt file I created with timecodes. I use the following code for that :

  #!/usr/bin/env python3
  
  import subprocess
  
  first = True
  
  with open('VideoSlicepoints_Python.txt') as f:
  
    for line in f.readlines():
  
      if first:
  
          first = False
  
      else:
  
          filename, VideoDing_Timecode, Video_R4Start, Video_R4End, Video_R24Start, Video_R24End, Video_R0plus15 = line.strip().split(';')
  
          cmd = ['ffmpeg', '-i', filename, '-ss', Video_R4Start, '-to', Video_R4End, '-c', 'copy', '"S:/_RobotThesis/VideoRounds/' + filename[:-4] + '_r4' + filename[-4:] + '"']
  
          print(" ".join(cmd))
  
          subprocess.run(cmd, stderr=subprocess.STDOUT)

  This returns me with the following error when it is trying to loop over to videos :

  [NULL @ 0000027cddf8a100] Unable to find a suitable output format for '"S:/_RobotThesis/VideoRounds/log1_front_r4.MTS"'
  
  "S:/_RobotThesis/VideoRounds/log1_front_r4.MTS": Invalid argument

  Now, I thought it was a formatting issue, but when I input the command directly (as is visible in the CMD prompt), it works just fine :

  ffmpeg -i log1_front.MTS -ss 09:37.1 -to 11:37.1 -c copy "S:/_RobotThesis/VideoRounds/log1_front_r4.MTS"

  For reference, this is an excerpt of the .txt file I am using (it is based on a csv file, that’s why it has headers and I excluded the header in the script) :

  Filename;VideoDing_Timecode;Video_R4Start;Video_R4End;Video_R24Start;Video_R24End;Video_R0plus15
  
  log1_front.MTS;04:44.0;09:37.1;11:37.1;28:00.3;30:00.3;19:44.0
  
  log2_front.MTS;03:50.0;08:11.2;10:11.2;19:44.9;21:44.9;18:50.0
  
  log3_front.MTS;04:10.1;08:32.4;10:32.4;16:49.2;18:49.2;19:10.1
  
  log5_front.MTS;01:14.7;04:50.2;06:50.2;14:24.5;16:24.5;16:14.7

  Edit :

  Here is the full output in the CMD, if needed :

• How to run the ffmpeg command using node.js ?

  12 juillet 2019, par Sachin Shah

  In node, When I got the request from /playMovie from App, I need to broadcast the video.

  When I execute this command in terminal it works fine.

  ffmpeg -re -i movie.mkv  -c:v libx264 -preset superfast -tune zerolatency -c:a aac -ar 44100 -f flv rtmp://192.168.1.13/live/myStream

  Now I’m going to setup this dynamic.

  app.use('/playMovie', function (req, res) {
  
    console.log("playMovie...");
  
    let filePaht = 'movie.mkv';
  
    let fileName = 'marvel-avengers';
  
  
  
    let ffmpeg = spawn(`ffmpeg -re -i ${filePaht}  -c:v libx264 -preset 
  
      superfast -tune zerolatency -c:a aac -ar 44100 -f flv 
  
  rtmp://192.168.1.13/live/${fileName}`);
  
       ffmpeg.on('exit', (statusCode) => {
  
     console.log("statusCode ::::::::::::::::::::::::::::::::: ",statusCode);
  
     if (statusCode === 0) {
  
        console.log('conversion successful')
  
     }
  
   })
  
  
  
  ffmpeg
  
    .stderr
  
    .on('data', (err) => {
  
      console.log('err:', new String(err))
  
    })
  
  });

  While run the app I got this error.
