• How can i cut a video from a specific timeline and save the cut area using ffmpeg ?

  17 novembre 2015, par Sharondohp Sharonas

  I have a Mov file i also have the file in Avi after converted it to Avi.
  What i want to do is to cut a part of the file from minute 1:10 until 1:50

  What i tried so far :

  using System;
  
  using System.Collections.Generic;
  
  using System.ComponentModel;
  
  using System.Data;
  
  using System.Drawing;
  
  using System.Linq;
  
  using System.Text;
  
  using System.Threading.Tasks;
  
  using System.Windows.Forms;
  
  using System.Diagnostics;
  
  
  
  namespace CutVideos
  
  {
  
      public partial class Form1 : Form
  
      {
  
          // 1:10 to 1:50
  
  
  
          public Form1()
  
          {
  
              InitializeComponent();
  
  
  
              Process.Start("ffmpeg.exe",
  
                "-sameq -t 10 -i E:\\New folder (29)\\MVI_7747.avi E:\\New folder (29)\\10seconds.avi");
  
          }
  
  
  
          private void Form1_Load(object sender, EventArgs e)
  
          {
  
  
  
          }
  
      }
  
  }

  First i tried to mov file then the avi in both cases it didn’t create the output file.
  For testing i did that it will cut only the first 10 seconds of the movie file. But it’s not working. Later i want to cut and save the part from minute 1:10 to 1:50

  I noticed that there is an error i think with the ffmpeg when running the program but i couldn’t see it since the console window is closing too fast.

• remove a subpart from the middle of a video

  22 mars 2020, par OneWorld

  I am trying to remove a middle part from a video from 2 to 3 seconds using FFMPEG. So that the video plays with the start, and the end but without the middle part between 2 to 3 seconds.

  This page helped a little bit
  https://superuser.com/questions/681885/how-can-i-remove-multiple-segments-from-a-video-using-ffmpeg

  My code is as follows :-

  ffmpeg -i input.mp4 -filter_complex "[0:v]trim=start=2:end=3,setpts=PTS-STARTPTS, concat[out1]" - map [out1] output_without_2_to_3_secs.mp4

  However with this code I get the following error message

  Cannot find a matching stream for unlabeled input pad 1 on filter Parsed_concat_2. I’m using a Mac.

  Any suggestions much appreciated

• Remuxing DIVX to MP4 for iDevices

  16 octobre 2013, par Chris Robinson

  Please note, everything I refer to hereafter is using ffmpeg.

  I have a DIVX video which has an mpeg4 codec (MPEG4 Part 2) and an mp3 audio stream as given by ffmpeg -i file.avi. It's my understanding that I should simply be able to remux into an mp4 container for use with iTunes and iDevices by

  ffmpeg -i file.avi -vcodec copy -acodec copy output.mp4

  seeing as both codecs are complient with the Mpeg4 Part 14 specification. However I can't import these files into iTunes. I'm assuming this is because the FourCC of the original stream has been set to DIVX.

  Is there an easy way to change this without re-encoding the video stream ? I'm looking to remux rather than re-encode to keep losses to a minimum and because I have a massive library of DIVX files that I want to import into iTunes and ffmpeg is easily scriptable for addition of future files.
