  I have skipped few lines of output as there are many frames. So if you see at the end of output on both A and B sides and look at the number of I, P and B frames,the number of P and B frames on receiver B is more than that at sender A. Can anyone please tell me why there is a change in the number of frames ?

  I am a novice at ffmpeg and have recently taken over a code base built by a previous engineer. The FFmpeg code is on an app engine that will edit the videos when they are uploaded.

  


  This code generated a title animation that will later be used as an overlay.

  


  exports.generateTitleAnimation = function(metadata, destPath, options = {}) {
const peeqLogoPath = "/app/assets/peeq-logo.png";
const whiteBarMovPath = "/app/assets/whiteBar.mov";
const titleFontPath = "/app/assets/Sofia-Pro-Black.otf";
const dateStrFontPath = "/app/assets/Sofia-Pro-Medium.otf";
const outputDuration = 5.52;
const src01 = "color=c=white:s=1920x1080:duration=" + outputDuration;
const src02 = "color=c=white@0.0:s=1920x1080:r=120:duration=" + outputDuration;

var dateStrXOffset = "(92";
var filterComplexStr = "[1]";

if (metadata.title) {
    const title = metadata.title.toUpperCase();
    filterComplexStr += "drawtext=fontfile=" + titleFontPath + ":text='" + title + "':x='floor(92*(min((t-1.75)^29,0)+max((t-3.75)^29,0)+1))':y=622+30+2:fontsize=70:fontcolor=black:ft_load_flags=render,";
}
if (metadata.subTitle) {
    const subTitle = metadata.subTitle.toUpperCase();
    filterComplexStr += "drawtext=fontfile=" + titleFontPath + ":text='" + subTitle + "':x='floor(92*(min((t-2.0)^29,0.0)+max((t-3.8)^29,0.0)+1.0))':y=622+184-20-60+9:fontsize=46:fontcolor=black:ft_load_flags=render,";

    dateStrXOffset += "+30*" + (subTitle.length + 1);
}
if (metadata.dateStr) {
    filterComplexStr += "drawtext=fontfile=" + dateStrFontPath + ":text='" + metadata.dateStr + "':x='floor(" + dateStrXOffset + ")*(min((t-2.0)^29,0.0)+max((t-3.8)^29,0.0)+1.0))':y=622+184-20-60+9:fontsize=46:fontcolor=black:ft_load_flags=render,";
}
console.log("generateTitleAnimation generating")

  However, this error only occurs on the app engine. Running nom test on my Mac generates the title perfectly.

  I am trying to figure out how to fix these errors :

  Error while filtering: Cannot allocate memory
  
  Failed to inject frame into filter network: Cannot allocate memory
  
  Error while processing the decoded data for stream #2:1

  Observation #1

  If I run the following command on stream #2:1 by itself :

  ffmpeg -i video1c.flv -vcodec libx264 -acodec aac video1c.mp4

  The files is converted fine with no errors.

  Observation #2

  Running MediaInfo on video1c.flv (stream #2) shows the following :

  Format: Flash Video
  
  Video Codecs: On2 VP6
  
  Audio Codecs: Nellymoser

  Any help would be appreciated in resolving this error.

  Update #1

  I have tried splitting the filter graph into two as requested but I receive the same errors :

  Error while filtering: Cannot allocate memory
  
  Failed to inject frame into filter network: Cannot allocate memory
  
  Error while processing the decoded data for stream #1:1

  However, I did discover something, if I try to bring up stream #1:1 mentioned above (video1b.flv) using VLC Media Player, I can hear the audio file but I cannot see the video and I receive this error message :

  No suitable decoder module:
  
  VLC Does not support the audio or video format "undf".
  
  Unfortunately there is no way for you to fix this.

  Update #2

  The above error was with the 32bit version of ffmpeg. I switched to a 64 bit machine and am now running the 64 bit ffmpeg version ffmpeg-20180605-b748772-win64-static.

  Now I no longer receive the following error :

  Error while processing the decoded data for stream #1:1

  But, I have a new error. About an hour into running it, I receive the following error :

  av_interleaved_write_frame(): Cannot allocate memory
  
  [mp4 @ 000000000433f080] Application provided duration: 3327365388930198318
  
  / timestamp: 17178820096 is out of range for mov/mp4 format

  I also tried first remuxing all the files as suggested and using those files to run the above command and that did not help. I still get the same error.
