• Videos to jpg image ffmpeg error

  14 mai 2017, par Loic Bch

  i’m making a program in c# in wich i’m using ffmpeg to cut video into frames.
  i’m doing it this way in my program :

  ffmpegPath = "C:\\Program Files (x86)\\ffmpeg\\ffmpeg32.bat";
  
  string videoPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "video.avi");
  
  
  
  Process process = new Process();
  
              process.StartInfo.FileName = ffmpegPath;
  
              process.StartInfo.Arguments = @"-i " + videoPath + " -qscale:v 2 image%03d.jpg";
  
              //process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
  
              process.Start();   // On cut la vid avec ffmpeg 

  This code works perfectly fine in debugging mod and display all my images
  Now i want to make a setup to install the program, so i’m using InnoSetup to make a setup but when i install the program and try to run the same code it display the commande prompt with ffmpeg error :
  "cannot display image2.jpg : av_interleaved_write_frame() : I/O error occurred
  ffmpeg error

  if someone can help me on why i’m getting this error in release and not in debug mode ? Why ffmpeg cant execute the request correctly after the setup since i’m changing nothing ?

  I already tried to double the % on ffmpeg request but it didnt works, all the path are correct and the input file is not damaged or anything.
  The ffmpeg request works fine when i execute it directly from the prompt.

• Livestream programatically generated audio/video over RTMP [on hold]

  13 février 2018, par user2649681

  I’m looking for a way to stream data generated by a program over RTMP without saving it to an intermediate file to then stream with ffmpeg. For example, if I have a program to run that constantly generates white noise as samples of audio(e.g. a function that outputs a random sample run within an infinite loop), and, if possible, a screen of a solid, random color, is there a way for me to this audio over RTMP more or less as it’s being generated ? I would imagine, if this is possible, it may involve something along the lines of building up buffers of a fixed number of audio samples and then streaming it somehow over RTMP.
