  lavc/dnxhddata : Do not print frame rates with supported profiles.
  The list is unmaintained, misleading and the frame rates are

• Can't share few FFMPEG encoded videos on WhatsApp

  2 juin 2019, par t6nand

  I am using FFMPEG to stitch a video to another video. However, I have observed that few of these videos are not being shared on WhatsApp with the message "Can’t send this video. Choose a different video and try again".

  I am using the following command for stitching :

  ffmpeg -y -i <input1> -i
  
   <input2> -filter_complex "color=black:input1Width x input1Height:d=(input1time + input2time -1)[base]
  
  ;[0:v]setpts=PTS-STARTPTS[v0];[1:v] scale = iw * min(input1Width / iw\\, input1Height / ih):ih * min(input1Width/iw\\,input1Height/ih),
  
  pad=input1Width:input1Height:(input1Width-iw*min(input1Width/iw\\,input1Height/ih))/2:(input1Height -
  
   ih*min(input1Width/iw\\,input1Height/ih))/2,setsar=1:1,format=yuva420p,fade=in:st=0:d=1.0:alpha=1,
  
  setpts=PTS-STARTPTS+((input1Time - 1)/TB)[v1];[base][v0]overlay[tmp]; [tmp][v1]overlay,format=yuv420p[fv];
  
  [0:a][1:a]acrossfade=d=1[fa]" -map [fv] -map [fa] -crf 23 -c:v libx264 -b:v 300K 
  
  -preset slow outputvideo.mp4
  
  </input2></input1>

  Here : input1Width - Input 1 Video’s width, input1Height - Input 2 Video’s height.

  Interestingly running this command directly on terminal produces a file which plays correctly on media players and I am able to share it across platforms including WhatsApp.

  However, the same command when triggered from a java code produces a similar file in terms of size, bit rate (near about same as produced when directly executed). I am running the same command from java using ProcessBuilder like :

  ProcessBulider stitchVideoCommandArray = new ProcessBuilder(
  
                          "ffmpeg", "-y",
  
                          "-i", <input1>,
  
                          "-i", <input2>,
  
                          "-filter_complex", "color=black:" + String.valueOf(width) + "x" + String.valueOf(height) + ":d=" +
  
                          String.valueOf(originalVideoTime + ASSET_VIDEOSTREAM_DURATION - CROSS_FADE_TIME_DURATION) + "[base];" +
  
                          "[0:v]setpts=PTS-STARTPTS[v0];[1:v]scale=iw*" + String.valueOf(minMultiplicable) + ":ih*" + String.valueOf(minMultiplicable) +
  
                          ",pad=" + String.valueOf(width) + ":" + String.valueOf(height) + ":(" + String.valueOf(width) + "-iw*" + String.valueOf(minMultiplicable) + "/2" +
  
                          "):(" + String.valueOf(height) + "-ih*" + String.valueOf(minMultiplicable) + "/2)" + ",fade=in" +
  
                          ":st=0:d=" + String.valueOf(CROSS_FADE_TIME_DURATION) + ":alpha=1,setpts=PTS-STARTPTS+((" + String.valueOf(originalVideoTime - CROSS_FADE_TIME_DURATION) +
  
                          ")/TB)[v1];[base][v0]overlay[tmp];[tmp][v1]overlay,format=yuv420p[fv];[0:a][1:a]acrossfade=d=1[fa]",
  
                          "-map", "[fv]",
  
                          "-map", "[fa]",
  
                          "-c:v", MP4Transcode.MP4VideoStreamEncoder.H264.videoEncoders,
  
                          "-b:v", "300K",
  
                          "-c:a", MP4Transcode.MP4AudioStreamEncoders.AAC.audioEncoders,
  
                          "-b:a", "128K",
  
                          "-crf", String.valueOf(constantRateFactor),
  
                          "-preset", presetRequired,
  
                      outputVideoPath
  
              );
  
  </input2></input1>

  I then use this object to execute the command using

  command.start()

  and waiting for exitvalue using

  command.waitFor()

  This also produces a file which I am able to play correctly on media players but was not successful in sharing the video on WhatsApp.

  Also, the file produced by executing FFmpeg commands as mentioned above from java produces media files with their loudness slightly increased.

  I am not able to figue out if it’s video specific issue or something else. It only happens to few random videos.

  Here are the links to videos with the problem :
  input 1 - input1Link
  input 2 - inpt2Link

  EDIT 1 :
  To add, adding -loglevel debug in java command takes forever and I haven’t seen it yet responding for even 5-6 minutes. However, using it directly from terminal returns quickly after processing.

  I want to add tags to mp3 converted by youtube-dl & ffmpeg :

  


  


  youtube-dl -o
'/Output/qpgTC9MDx1o.mp3' qpgTC9MDx1o -f bestaudio —extract-audio —metadata-from-title "%(artist)s -
%(title)s" 2>&1

  


  


  I have this error in the output result :
