• Ffmpeg - Concat two video file - Defining absolute path of video file not working

  9 juillet 2014, par Ghanshyam Dobariya

  I am using Ffmpeg to concate three mp4 files.

  I am following this article
  https://trac.ffmpeg.org/wiki/How%20to%20concatenate%20(join,%20merge)%20media%20files

  Check topic Concat protocol

  I have 3 .ts files, now running following command that merges all 3 .ts files properly

  ffmpeg -i "concat:video1.ts|video2.ts|video3.ts" -c copy -bsf:a aac_adtstoasc output.mp4 

  Now same command I want to run from php code, so I am giving absolute path of each file, and the command is as below.

  /home/pc-16/bin/ffmpeg -i "concat:|'/var/temp/rt-web/web/video/iRec/HOKPINzHFS/video1.ts'|'/var/temp/rt-web/web/video/iRec/HOKPINzHFS/video2.ts'|'/var/temp/rt-web/web/video/iRec/HOKPINzHFS/video3.ts'" -c copy -bsf:a aac_adtstoasc "/var/temp/rt-web/web/video/iRec/HOKPINzHFS/final.mp4"

  This gives following error

  concat:|'/var/temp/rt-web/web/video/iRec/HOKPINzHFS/video1.ts'|'/var/temp/rt-web/web/video/iRec/HOKPINzHFS/video2.ts'|'/var/temp/rt-web/web/video/iRec/HOKPINzHFS/video3.ts': No such file or directory

  Have also tried the same command by removing single quotes from file names

  /home/pc-16/bin/ffmpeg -i "concat:|/var/temp/rt-web/web/video/iRec/HOKPINzHFS/video1.ts|/var/temp/rt-web/web/video/iRec/HOKPINzHFS/video2.ts|/var/temp/rt-web/web/video/iRec/HOKPINzHFS/video3.ts" -c copy -bsf:a aac_adtstoasc "/var/temp/rt-web/web/video/iRec/HOKPINzHFS/final.mp4"

  but got the same error message.

  Can anybody tell me how to specify absolute file names in command.

• Stop JavaCV playback warning

  18 janvier 2018, par Chaoslab

  Problem :
  Receiving a stream of command line warnings as video plays - deprecated pixel format used, make sure you did set range correctly

  Question :
  How can I stop the warnings from happening or being displayed ?

  Update - Fixed :
  The solution was too override the logging callback and don’t do anything in the logging call method. FFmpeg logging is then disabled.

  The reason for the message from FFmpeg is because it is grabbing frames from an old video format so is unavoidable if playing older videos.

  NOTE :
  This solution completely disables all output from FFmpeg. Even FFmpeg errors are muted.

  Code below (just frame grabbing, not timed playback).

  package test.javacv;
  
  
  
  import java.io.File;
  
  
  
  import org.bytedeco.javacv.CanvasFrame;
  
  import org.bytedeco.javacv.FFmpegFrameGrabber;
  
  import org.bytedeco.javacv.Frame;
  
  
  
  import org.bytedeco.javacv.CustomLogCallback;
  
  
  
  public class TestPlay implements Runnable {
  
   private static String      video_loc = null;
  
   private static CanvasFrame canvas    = new CanvasFrame("Test JavaCV player");
  
  
  
   public static void main(String[] args) { new Thread(new TestPlay(args[0])).start(); }
  
  
  
   static {
  
    CustomLogCallback.set();
  
   }
  
  
  
   public void run() { play_video(video_loc); }
  
  
  
   public TestPlay(String loc) {
  
    video_loc = loc;
  
    canvas.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
  
   }
  
  
  
   public static final void play_video(String vid_loc) {
  
    try {
  
     File               file      = new File(vid_loc);
  
     FFmpegFrameGrabber ffmpeg_fg = new FFmpegFrameGrabber(file.getAbsolutePath());
  
     Frame              frm;
  
     ffmpeg_fg.setAudioChannels(0);
  
     ffmpeg_fg.start();
  
     for(;;)
  
      if((frm = ffmpeg_fg.grab()) != null) canvas.showImage(frm);
  
      else {
  
       ffmpeg_fg.setTimestamp(0);
  
       break;
  
      }
  
     ffmpeg_fg.stop();
  
    } catch(Exception ex) { ex("play_video vid_loc:" + vid_loc, ex); }
  
   }
  
  
  
   public static final void ex(String txt, Exception ex)   {
  
    System.out.println("EXCEPTION: " + txt + " stack..."); ex.printStackTrace(System.out); }
  
  }

  Logging class

  // custom logger to override all logging output
  
  package org.bytedeco.javacv;
  
  
  
  import org.bytedeco.javacpp.BytePointer;
  
  
  
  import static org.bytedeco.javacpp.avutil.LogCallback;
  
  import static org.bytedeco.javacpp.avutil.setLogCallback;
  
  
  
  public class CustomLogCallback extends LogCallback {
  
  
  
   static final CustomLogCallback instance = new CustomLogCallback();
  
  
  
   public static CustomLogCallback getInstance() { return instance; }
  
  
  
   public static void set() { setLogCallback(getInstance()); }
  
  
  
   @Override
  
   public void call(int level, BytePointer msg) {}
  
  }

• ffmpeg encode video produce incorrect mediainfo encoding settings

  I've been trying to do batch encode videos to H265 format. I am using media-autobuild_suite to build ffmpeg and have already updating ffmpeg to the latest version.

  However, the Writing library and Encoding settings output is incorrect. Before update ffmpeg doesn't have this issue. I wonder what have been missing that causing this issue.

  I have tried with simplest ffmpeg from official wedsite and encoding cli but the output still same.

  


  ffmpeg -i "input.mkv" -c:v libx265 "output.mkv"


  


  Update :
Tried converting video with FFmpeg 4.4 "Rao" from https://www.ffmpeg.org/ working fine. But compiled ffmpeg from media-autobuild_suite, tried with light build and full build, Writing library and Encoding settings output still incorrect.
