• 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');

• 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 ?

• Corrupt playback of .flv when using JW Player

  21 mai 2012, par Adam Ingmansson

  This question is also asked on Audio-Video Production

  I have some files that when played in jwplayer the playback is corrupt.
  The files are encoded to h.264 using FFMpeg and there is other files encoded in the same way that works.

  At the moment we only use the flash version of the player.

  The corrupt playback looks like this :

  http://adam.ingmansson.com/public/jwplayer-corrupt-video.png

  This problem started showing up after we did an upgrade to FFMpeg, so I haven't ruled out that it could be an encoding error.

  the command used to run FFMpeg is :

  ffmpeg 
  
      -i /home/ftp/1c8f08b7d0d9e7fa4b24066156ad50bc981497a0.mov 
  
      -vcodec libx264 
  
      -preset ultrafast 
  
      -profile baseline 
  
      -acodec libfaac 
  
      -ab 96k 
  
      -crf 19 
  
      -vf movie="/home/adam/logo.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" 
  
      -y /home/ftp/1c8f08b7d0d9e7fa4b24066156ad50bc981497a0.flv

  I am in no way an expert in FFMpeg commandline, so feel free to point out any mistakes made.

  EDIT :

  A coworker was able to view a "corrupted" file. The only difference between my computer and his is that he have a Mac. Same flash version, same JW Player version. Something is not right here.
