• 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;      
  
                  psiProcInfo.WindowStyle = ProcessWindowStyle.Hidden;    
  
                  psiProcInfo.RedirectStandardError = true;             
  
                  psiProcInfo.RedirectStandardOutput = true;         
  
                  psiProcInfo.CreateNoWindow = true;                 
  
                  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.

• Issue trying to stream RTSP to RTMP (live) through NGINX

  30 juin 2016, par taansari

  I want live RTMP streaming through nginx. I setup this server on a public ip (linux - CentOS), using this tutorial : https://notehub.org/rcfdu.

  My target is : RTSP source -> transcode to RTMP -> recieve on nginx (live ip),

  Then, I want to receive this stream through server ; something like :

  nginx -> ffplay.

  On transmission side, I have ffmpeg application, and on receiver side, I have ffplay application.

  I have setup everything I could think of, and I can see it is properly setup (apparently). But, when I try to stream using similar command :

  ffmpeg -i rtsp://aaa.bb.ccc.ddd/vod/mp4:filename.mov -f mpegts rtmp://<live ip="ip" address="address">:1935/live/
  
  </live>

  I get lots of messages (where everything looks alright) :

  ffmpeg -i rtsp://aaa.bb.ccc.ddd/vod/mp4:filename.mov -f mpegts rtmp://<live ip="ip" address="address">:1935/live/

  I can telnet into both port 80 and 1935, and made sure port 1935 is open as input and output in iptables...

  -A INPUT -m state --state NEW -m tcp -p tcp --dport 1935 -j ACCEPT
  
  -A OUTPUT -m state --state NEW -m tcp -p tcp --dport 1935 -j ACCEPT

  but nothing works.

  Can anyone help in this regards ?

• Compiling tutorial programs on FFMPEG

  29 janvier 2012, par iwant2learn

  How do i compile the sample programs given in FFMPEG. i am not able to compile as i get
  error as CODEC_TYPE_VIDEO undeclared. Can any one please suggest me how to compile the programs. I am using ubuntu 11.

  This is the first example :

  $ gcc -o tutorial01 tutorial01.c -lavutil -lavformat -lavcodec -lz

  This is the output I got :

  tutorial01.c: In function ‘main’: tutorial01.c:77:3: warning: ‘dump_format’ is deprecated (declared at /usr/local/include/libavformat/avformat.h:1462)
  
  tutorial01.c:82:51: error: ‘CODEC_TYPE_VIDEO’ undeclared (first use in this function)
  
  tutorial01.c:82:51: note: each undeclared identifier is reported only once for each function it appears in
