• 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.

• ffmpeg background worker runs in debug but not in application

  2 novembre 2019, par Purgitoria

  My application has a function of taking captured images and using an FFmpeg background worker to stitch these into a time-lapse video. The GUI has some simple options for video quality and for the source folder and output file. I had an older version of my application written in VB.NET and that worked without issue but I am rewriting in C# as it supports additional capture and filter capability in the image processing but am having real trouble figuring out what is wrong with this function.

  I have tried relocating FFmpeg to different locations just in case it was a permissions issue but that had no effect and I also tried to put the function in a "try" with a message box to output any exceptions but I got different errors that prevented me from compiling the code. When I run the application from within VS 2015 in the debugging tool the function works just fine and it will create a video from a collection of still images but when I build and install the application it does not work at all and I cannot see what is causing it to fail. In the options for ffmpeg I used the -report to output a log of what happens in the background worker and in debug, it creates this log but from the application, it does not so I presume it is not even running ffmpeg and going straight to the completed stage of the function.

  Function startConversion()
  
  
  
      CheckForIllegalCrossThreadCalls = False
  
      Dim quality As Integer = trbQuality.Value
  
      Dim input As String = tbFolderOpen.Text
  
      Dim output As String = tbFolderSave.Text
  
      Dim exepath As String = Application.StartupPath + "\\bin\ffmpeg.exe"
  
      input = input & "\SCAImg_%1d.bmp"
  
      input = Chr(34) & input & Chr(34)
  
      output = Chr(34) & output & Chr(34)
  
  
  
      Dim sr As StreamReader
  
      Dim ffmpegOutput As String
  
  
  
      ' all parameters required to run the process
  
      proc.StartInfo.UseShellExecute = False
  
      proc.StartInfo.CreateNoWindow = True
  
      proc.StartInfo.RedirectStandardError = True
  
      proc.StartInfo.FileName = exepath
  
      proc.StartInfo.Arguments = "-framerate 25 -start_number 0 -pattern_type sequence -framerate 10 -i " & input & " -r 10 -c:v libx264 -preset slow -crf " & quality & " " & output
  
      proc.Start()
  
  
  
      lblInfo.Text = "Conversion in progress... Please wait..."
  
      sr = proc.StandardError 'standard error is used by ffmpeg
  
      btnMakeVideo.Enabled = False
  
      Do
  
          ffmpegOutput = sr.ReadLine
  
          tbProgress.Text = ffmpegOutput
  
      Loop Until proc.HasExited And ffmpegOutput = Nothing Or ffmpegOutput = ""
  
  
  
      tbProgress.Text = "Finished !"
  
      lblInfo.Text = "Completed!"
  
      MsgBox("Completed!", MsgBoxStyle.Exclamation)
  
      btnMakeVideo.Enabled = True
  
      Return 0
  
  
  
  End Function

  I checked the application folder and it does contain a subfolder \bin withe the ffmpeg.exe located within the folder so I then used cmd to run an instance of the installed ffmpeg from the application folder and it seemed to be throwing out permissions errors :

  Failed to open report "ffmpeg-20191101-191452.log" : Permission denied
  Failed to set value ’1’ for option ’report’ : Permission denied
  Error parsing global options : Permission denied

  This seems then like it is certainly a permissions problem but where I am not sure. I did not run into this error when using VB.NET so I am wondering where I am going wrong now. I thought perhaps it would just be a write permission in the application folder so I the removed the -report and ran ffmpeg again using cmd from my application folder and it then gave the error

  C :\Users\CEAstro\Pictures\AnytimeCap : Permission denied

  Am I missing something really obvious in my code or is there something more fundamental I have wrong in my setup ?

  I should also add that I tried running ffmpeg via cmd from a copy that was manually placed elsewhere (i used the same file) and that actually worked. For some reason, it seems like it just will not work from wherever my application installs it.

• I detected an error downloading a twitch tv stream. I use ffmpeg. That error stops the download, how can I fix it ? [closed]

  9 juin, par sort35ofn

  I wanted to perform a download via ffmpeg of a video streamed live on the Twitch tv platform. I have windows 10 and I use cmd to run ffmpeg.

  


  The command I use to download the concert is :

  


  ffmpeg.exe -i "m3u8-link" -c copy name.ts


  


  I once downloaded with yt-dlp, but noticed that the quality was noticeably lower, at least using the following command :
yt-dlp.exe -f (bestvideo+bestaudio/best) "amazon-channel-link"

  


  That's why I prefer to download with ffmpeg. Normally I haven't had any problems with downloads. But this is already the third time (not continuously/consecutively) that I get this error. That error causes the download of the stream to terminate. It is not like in other occasions that sometimes a .ts fragment (of 3 seconds, for example) has already expired (and is not included in the download) but the download continues.

  Is there any way to prevent this error ? Or can I do something so that the download does not stop because of this error ?

  


  And excuse me but I forgot to take a screenshot of the cmd screen, so I don't remember the colors of the letters (it certainly changed the colors of the letters when the error appeared). So I proceed to indicate that the error starts when it says : “ [hls @ 000001edab89e500] keepalive request failed for ”.
