• How to create a video from image buffers using fluent-ffmpeg ?

  23 juin 2016, par Zacky Pickholz

  I’ve been trying to create a slideshow from a series of images using nodejs + fluent-ffmpeg, however it is not working well or consistently. ffmpeg occasionally emits "Error : ffmpeg exited with code 1 : pipe:0 : Invalid data found when processing input", and in case an eventual video (mp4) is created it seems to be missing images/frames.

  The process is as follows : images are loaded into memory, transformed resized to same dimensions using lwip, written sequentially into a passthrough stream, which is fed to ffmpeg as input.

  Relevant code snippets :

  var lwip = require('lwip');
  
  var ffmpeg = require('fluent-ffmpeg');
  
  var stream = require('stream');
  
  var imagesStream = new stream.PassThrough();
  
  
  
  ...
  
  
  
  image.batch()
  
              .contain(options.video.width, options.video.height, 'lanczos')
  
              .toBuffer(options.frames.format, {quality: 100}, (err, buffer) => {
  
                  if (err) {
  
                      throw ('error convering image to buffer. ' + err);
  
                  }
  
                  imagesStream.write(buffer, 'utf8');
  
                  resolve();
  
              });
  
  
  
  ...
  
  
  
      ffmpeg(imagesStream)
  
          .inputOptions('-framerate 1/' + options.frames.secsPerImage)
  
          .input(path.join(AUDIO_ROOT, options.audio.track))
  
          .save(path.join(path.join(OUTPUT_FOLDER, `${options.video.output.prefix}${timestamp}.${options.video.output.format}`)))
  
          .size(`${options.video.width}x${options.video.height}`)
  
          .on('start', () => {
  
              console.log('creating the clip now...')
  
          })
  
          .on('progress', (progress) => {
  
              var progPercent = Math.round(100 * progress.frames / (numImages * options.frames.secsPerImage * 25));
  
              progPercent = Math.min(progPercent, 100);
  
              console.log(`processing: ${progPercent}% done`)
  
          })
  
          .on('stderr', (line) => {
  
              console.error('ffmpeg error: ' + line);
  
          })
  
          .on('error', (error) => {
  
              reject('ffmpeg transcoding error: ' + error);
  
          })
  
          .on('end', () => {
  
              console.log('done!');
  
              resolve(true);
  
          })
  
          .run();

  And here is the output :

• ffmpeg conversion using libx264 looks terrible - interlaced

  17 juin 2016, par justin

  I’m in the process of converting some files from my set-top box (.ASF) format to something more portable that will work with plex and roku more readily. In doing so I’m using ffmpeg, but having unsatisfying results. Whereas the original doesn’t have ANY notable interlacing defects, the converted file does. I think it has something to do with the libx264 converter because of the following experiment :

  Running this command :

  ffmpeg -i file.asf -vcodec copy -acodec copy -bsf:a aac_adtstoasc -ss 150 -t 15 short.mp4

  Which produces a file which has no interlacing artifact and appears to be same exact file size as the original (if run without the -ss and -t commands).

  Produces a file which has quite a bit of interlacing defect when playing on my HD projector thru Roku via Plex (direct play enabled, apparently no transcoding).

  

  Lest I be overly picky, I engaged my wife in this test, showing her the two files and she agreed that the one that used libx264 was significantly worse and unwatchable. Can’t figure out how to shrink this file down without causing these interlacing defects — it happens even when I don’t try to shrink it ! Any thoughts ?

  Video files :

  https://dl.dropboxusercontent.com/u/23091/m1/short.mp4
  https://dl.dropboxusercontent.com/u/23091/m1/short2.mp4

  Update : Additionally, I tried a few settings to generate a MPEG4 (.AVI) file and had similar lack of success. Similar interlacing defects.

• Why when converting avi video file to another format the first 2-3 seconds are blurry ?

  13 juin 2016, par Sharon Gabriel

  The source file is avi. The target new file is mp4.
  The first 2-3 seconds are blurry. Then after 2-3 second the whole video until the end is smooth and sharp.

  Another sub question is how come that 2.16 GB avi file after conversion using ffmpeg is only 1.34 MB ? It’s not part of a movie or something it’s collection of screenshots images i did in c# and then used AviFile Lib to create from them a avi video file. and yet from 2.16 GB to 1.34 MB and it keep the quality i think almost the same quality like the original avi file and the same duration 2:20 minutes.

  About the blurry problem this is my code where i set the ffmpeg arguments and set the process :

  private void Convert()
  
          {
  
              try
  
              {
  
                  Control.CheckForIllegalCrossThreadCalls = false;
  
                  if (ComboBox1.SelectedIndex == 3) 
  
                  {
  
                      strFFCMD = " -i " + (char)34 + InputFile + (char)34 + " -c:v libx264 -s 1920x1080 -pix_fmt yuv420p -qp 18 -profile high444 -c:a libvo_aacenc -b:a 128k -ar 44100 -ac 2 -y " + OutputFile;
  
                  }    
  
                  psiProcInfo.FileName = exepath;
  
                  psiProcInfo.Arguments = strFFCMD;        
  
                  psiProcInfo.UseShellExecute = false;

                  prcFFMPEG.StartInfo = psiProcInfo;           
  
                  prcFFMPEG.Start();
  
                  ffReader = prcFFMPEG.StandardError;
  
  
  
                  do
  
                  {
  
                      if (Bgw1.CancellationPending)
  
                      {
  
                          return;
  
                      }
  
                      Button5.Enabled = true;
  
                      Button3.Enabled = false;
  
                      strFFOUT = ffReader.ReadLine();                    
  
                      RichTextBox1.Text = strFFOUT;
  
                      if (strFFOUT != null)
  
                      {
  
                          if (strFFOUT.Contains("frame="))
  
                          {
  
                              currentFramestr = strFFOUT.Substring(7, 6).Trim();
  
                              Regex rx = new Regex(@"^\d+");
  
                              Match m = rx.Match(currentFramestr);
  
                              if (m.Success)
  
                              {
  
                                  currentFrameInt = System.Convert.ToInt32(m.Value);
  
                              }
  
                          }
  
                      }
  
                      string percentage = ((double)ProgressBar1.Value / (double)ProgressBar1.Maximum * 100.0).ToString();
  
                      textBox3.Text = ProgressBar1.Value.ToString();                    
  
                      ProgressBar1.Maximum = FCount + 1;
  
                      ProgressBar1.Value = (currentFrameInt);
  
                      Label12.Text = "Current Encoded Frame: " + currentFrameInt;
  
                      Label11.Text = percentage;
  
                  } while (!(prcFFMPEG.HasExited || string.IsNullOrEmpty(strFFOUT)));
  
              }
  
              catch(Exception err)
  
              {
  
                  string errors = err.ToString();
  
              }
  
          }

  psiProcInfo is ProcessStartInfo

  prcFFMPEG is Process

  And this is how it looks like when i play the target the new created converted video file the mp4 the first seconds :

  Duration : 00:02:20

  Width : 1920 Height : 1080

  Data Rate and Total Rate both : 80kbps

  Frame rate : 2 frames/second

  

  This is the output of the ffmpeg console while converting the file.
