• FFMPEG conversion error from MKV to MP4 using libfdk_aac codec

  23 août 2014, par Charlie Brown

  The purpose of doing this is because my "Smart" samsung TV doesn’t play MKV files.

  This thread mentions that there is no need for video conversion, just changing the container might suffice. After reading multiple threads on how to change the container of MKV to MP4, I downloaded and compiled the FFMPEG with libfdk_aac support from here. I tried converting a sample MKV file using this command :

  ffmpeg -i "C:\VideoTest\Sample1.mkv" -c:v copy -c:a libfdk_aac -b:a 384k "C:\VideoTest\Sample2.mp4"

  but getting the following errors (copied from command prompt) :

  [hevc @ 0000000000308ae0] Could not find ref with POC 113
  
  [hevc @ 0000000000308ae0] Could not find ref with POC 111

  Any help would be appreciated.

• ffmpeg creating image slideshow in audio concat command

  17 janvier 2023, par Martin

  I have a working ffmpeg which when ran in windows 10 command prompt will combine 3 audio files with 1 image file into a video.
The single image file is used as just a static image for the entire video's duration. (16:50 or 1010 seconds)

  


  song1.mp3 00:00:00-00:06:23
song2.mp3 00:06:23-00:12:04
song3.wav 00:12:04-00:16:50


  


  I am trying to change this so that instead of a single static image, I have a slideshow of 4 different images play during the duration of the video.
I was thinking of doing this by taking the total length in seconds (1010) divided by 4 would mean 252.5 seconds per image, so a timeline like :

  


  img1: 0     - 252.5
img2: 252.5 - 505
img3: 505   - 757.5
img4: 757.5 -  252.5


  


  How can I change my command so that the output video is a slideshow of images with the timestamps above ?
Here is my working ffmpeg command with explanation from myself which hopefully explains some of it :

  


  ffmpeg -loop 1 -framerate 2 -i "C:\Users\...local_filepath...\ffmpeg-commands\images\img1.png" -i "C:\Users\...local_filepath...\ffmpeg-commands\audio files\song1.mp3" -i "C:\Users\...local_filepath...\ffmpeg-commands\audio files\song2.mp3" -i "C:\Users\...local_filepath...\ffmpeg-commands\audio files\song3.wav" -c:a pcm_s32le -filter_complex concat=n=3:v=0:a=1 -vcodec libx264 -bufsize 3M -filter:v "scale=w=640:h=638,pad=ceil(iw/2)*2:ceil(ih/2)*2" -crf 18 -pix_fmt yuv420p -shortest -tune stillimage -t 1010 "C:\Users\...local_filepath...\ffmpeg-commands\videos\outputvideo.mkv"


ffmpeg

//loop single image 
-loop 1 
//set video framerate
-framerate 2 
//take image and audio files
-i "C:\Users\...local_filepath...\ffmpeg-commands\images\img1.png" 
-i "C:\Users\...local_filepath...\ffmpeg-commands\audio files\song1.mp3" 
-i "C:\Users\...local_filepath...\ffmpeg-commands\audio files\song2.mp3" 
-i "C:\Users\...local_filepath...\ffmpeg-commands\audio files\song3.wav"
//set audio codec
-c:a pcm_s32le 
//organize the audio files (?)
-filter_complex concat=n=3:v=0:a=1 
//set video codec
-vcodec libx264 
//limiting the output bitrate
-bufsize 3M 
//scale single image to 640x638 resolution
-filter:v "scale=w=640:h=638,pad=ceil(iw/2)*2:ceil(ih/2)*2" 
//range of the CRF scale is 0–51, where 0 is lossless (for 8 bit only, for 10 bit use -qp 0), 23 is the default, and 51 is worst quality
-crf 18 
//set pixel format
-pix_fmt yuv420p 
//try to ensure video is not longer then concatenated audio files
-shortest 
//use still image 
-tune stillimage 
//specify output video time to ensure it is exactly the same length as concattenated audio
-t 1010 
//specify output filepath
"C:\Users\...local_filepath...\ffmpeg-commands\videos\outputvideo.mkv"


  


  And here is the command raw how you would run it.

  


  ffmpeg -loop 1 -framerate 2 -i "C:\Users\marti\Documents\projects\jan2023-rendertune\ffmpeg-commands\images\img1.png" -i "C:\Users\marti\Documents\projects\jan2023-rendertune\ffmpeg-commands\audio files\song1.mp3" -i "C:\Users\marti\Documents\projects\jan2023-rendertune\ffmpeg-commands\audio files\song2.mp3" -i "C:\Users\marti\Documents\projects\jan2023-rendertune\ffmpeg-commands\audio files\song3.wav" -c:a pcm_s32le -filter_complex concat=n=3:v=0:a=1 -vcodec libx264 -bufsize 3M -filter:v "scale=w=640:h=638,pad=ceil(iw/2)*2:ceil(ih/2)*2" -crf 18 -pix_fmt yuv420p -shortest -tune stillimage -t 1010 "C:\Users\marti\Documents\projects\jan2023-rendertune\ffmpeg-commands\videos\concatVideo-250771.mkv"

• ffmpeg fails to convert an uploaded video file whose size greater than 14mb when executed through c#.net

  10 novembre 2017, par Harun

  I am converting videos to flv using ffmpeg.exe through c# and the process gets stuck and the conversion fails if the file size exceeds 14mb. I’ve tried to run ffmpeg directly through command prompt and it works fine regardless of size.

  My conversion code is as follows :

  OutputFile = SavePath + "SWF\\" + WithOutExt + ".flv";
  
  FilArgs = string.Format("-i {0} -ar 22050 -qscale 1 {1}",InputFile,OutputFile);
  
  
  
  Process proc;
  
  proc = new Process();
  
  
  
  try
  
  {
  
       proc.StartInfo.FileName = spath + "\\ffmpeg\\ffmpeg.exe";
  
       proc.StartInfo.Arguments = FilArgs;
  
       proc.StartInfo.UseShellExecute = false;
  
       proc.StartInfo.CreateNoWindow = false;
  
       proc.StartInfo.RedirectStandardOutput = true;
  
       proc.StartInfo.RedirectStandardError = true;
  
       proc.Start();
  
  
  
       string StdOutVideo = proc.StandardOutput.ReadToEnd();
  
       string StdErrVideo = proc.StandardError.ReadToEnd();
  
   }
  
   finally
  
   {
  
       proc.WaitForExit();
  
       proc.Close();
  
   }

  When I tried to manually stop the running process The stderroutput is as follows :
