• C++ OpenCV 3.4 / FFMPEG 3.4.1 VideoWriter and MP4 Output File Format

  11 janvier 2019, par PhilBot

  I’m running on an ARM BeagleBone X-15 Debian machine with Linux Kernel 4.9.35-ti-r44. In my C++ ( Qt 5 ) application, I want to save my cv::Mat frames to an MP4 format video. I have libx264 installed and compiled from scratch both ffmpeg and OpenCv. I can successfully record and view video with MJPEG with the AVI video container type but not MP4. Whenever I try to write an MP4 video, I get run time errors of the form :

  OpenCV: FFMPEG: tag 0x44495658/'XVID' is not supported with codec id 13 and format 'mp4 / MP4 (MPEG-4 Part 14)'
  
  OpenCV: FFMPEG: fallback to use tag 0x00000020/' ???'

  I’ve tried various Google answers but none have worked.

  Relevant code :

  cv::Size frameSize = frame.size();
  
  
  
  qDebug() << "Initializing Video Recording to save Video file here: " << destinationFileName;
  
  
  
  std::string filename = destinationFileName.toStdString();
  
  //int fcc =   CV_FOURCC('M','J','P','G');
  
  //int fcc =   CV_FOURCC('X','2','6','4');
  
  int fcc = CV_FOURCC('X','V','I','D');
  
  int fps =   1;
  
  videoRecorder = new cv::VideoWriter(filename,fcc,fps,frameSize);
  
  
  
  ...
  
  
  
  videoRecorder->write(frame);

  I’ve downloaded and built the latest OpenCV 3.4 but the problem persists.
  How can I write to an MP4 File with OpenCV’s video writer ?

  When I try the ’X’,’2’,’6’,’4’ format I get the error :

• Concatenating video using FFMPEG wrapper class [duplicate]

  • how to use ffmpeg to apply 1:1 SAR before concat on large complex filter
    
    1 answer
    

  I am trying to concatenate video using NReco.VideoConverter wrapper class made for FFMPEG.

  I have three video files with the same frame rate and same frame size.

  Here is what I have done.

          string toconcatfile = @"C:\Users\Alan\Desktop\Black.mp4";
  
          string output1 = @"C:\Users\Alan\Desktop\output1.mp4";
  
          string output2 = @"C:\Users\Alan\Desktop\output2.mp4";
  
          string finaloutput = @"C:\Users\Alan\Desktop\finaloutput.mp4";

  All the three videos have a frame rate of 25 and Video frame size yet it fails when I add in toconcatfile to the final conversion method.

  It works when its just output1 and output2 meaning there must be a different setting in toconcatfile.

  Here is what I have tried.

          FFMpegConverter fFMpeg = new FFMpegConverter();
  
  
  
  
  
          //Slices first video
  
          ConvertSettings settings = new ConvertSettings
  
          {
  
              VideoFrameRate = 25,
  
              VideoFrameSize = FrameSize.hd480,
  
              MaxDuration = startcut,
  
              AudioSampleRate = 44100
  
  
  
          };
  
  
  
          //Slices second video
  
          ConvertSettings settings2 = new ConvertSettings
  
          {
  
              VideoFrameRate = 25,
  
              VideoFrameSize = FrameSize.hd480,
  
              Seek = endcut,
  
              AudioSampleRate = 44100
  
  
  
          };
  
          //Copies framerate and size from the previous video to the concatenation video
  
          ConvertSettings settings3 = new ConvertSettings
  
          {
  
              VideoFrameRate = 25,
  
              VideoFrameSize = FrameSize.hd480,
  
              MaxDuration = 4,
  
              AppendSilentAudioStream = true,
  
              AudioSampleRate = 44100
  
  
  
          };
  
  
  
  
  
    string newblack = @"C:\Users\Alan\Desktop\newblack.mp4";
  
  
  
          //Slice method called
  
          fFMpeg.ConvertMedia(pathtofile, Format.mp4, output1, Format.mp4, settings);
  
          fFMpeg.ConvertMedia(pathtofile, Format.mp4, output2, Format.mp4, settings2);
  
          fFMpeg.ConvertMedia(toconcatfile, Format.mp4, newblack, Format.mp4, settings3);
  
  
  
          String[] inputfiles = new String[2];
  
          inputfiles[0] = output1;
  
          inputfiles[1] = newblack;
  
          //inputfiles[1] = output2;
  
  
  
  
  
          ConcatSettings concatSettings = new ConcatSettings
  
          {
  
              //CustomOutputArgs = output1+" "+ toconcatfile+ " "+output2+ " -filter_complex \"[0:v:0][0:a:0][1:v:0][1:a:0][2:v:0][2:a:0]concat=n=3:v=1:a=1[outv][outa]\" -map \"[outv]\" - map \"[outa]\""
  
          };
  
  
  
          fFMpeg.ConcatMedia(inputfiles, finaloutput, Format.mp4, concatSettings);

  Can anyone help ?

  Edit : I get the exception message - "Invalid argument (exit code : 1)",

• Creating a video using ffmpeg in a PHP script

  30 décembre 2017, par Femzy

  I have been trying to solve this problem for a while now, but i have not got it through please someone should help me..
  My main objective is to collect user’n inputs and convert it to a video with black background, then the input text will be moving from left to right while the video is playing with audio in the background. Currently i was suggested to use "drawtext" but i have not find it working
  This is the code I use just to test the drawtext but the thing is, if i try it 10 times it will create a video file ones in many times i tried and even the video file would have 0 kb in size
  The Below code is my code

  The Below is the Report i got from the not working ffmpeg cmmand

  echo shell_exec('ffmpeg -f lavfi -i testsrc=duration=5:size=800x600:rate=30 -vf drawtext="fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSerif-Bold.ttf:textfile=text.txt: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: box=1: boxcolor=0x00000000@1" -preset ultrafast outex.mp4');
