• Ffmpeg live streaming to Youtube - "Connect streaming software to start preview"

  10 septembre 2019, par Zoltan Fedor

  I have an rtsp feed (H.265) which I am trying to stream to YouTube Live, but whatever I do YouTube Studio just showing the waiting icon with "Connect streaming software to start preview".

  .sh file for streaming :

  VBR="1000k"
  
  FPS="30"
  
  QUAL="ultrafast"
  
  YOUTUBE_URL="rtmp://b.rtmp.youtube.com/live2"

  Basically all looks good to me - still, in YouTube Studio only the waiting icon with the "Connect streaming software to start preview" message is visible, not video feed.

  Any ideas ?

• how to fix "FFmpeg cannot edit existing files in-place."-Problem in Java

  7 juillet 2019, par Suione

  I am trying to write an audio file to an existing videofile. Unfortunately I get the Logmessage, that I cannot edit existing files in-place.

  I have found some threads about the so called muxing between video and audio, but none of them could help me out really. Maybe some one of you can.
  Further this isn`t my could either. I am only the one who needs to use it, so I have to fix it.

  Thanks for your help

  String[] args = { FFMPEG_FILE.getAbsolutePath(), "-y", "-i", videoPath, "-ss", String.valueOf(-offset.toFrames() / 50.0f), "-i", audioPath, "-c", "copy", "-map", "0:v", "-map","1:a", "-bsf:v", "h264_mp4toannexb","-r", String.valueOf(project.getFramerate()), "-shortest",outputPath };
  
  
  
  ProcessBuilder pb = new ProcessBuilder(args).inheritIO();
  
  Process p = pb.start();
  
  int exit = p.waitFor();
  
  if (exit != 0) {
  
       throw new IOException("ffmpeg terminated with a failure");
  
  }

  EDIT : As someone commented outputPath was same same as videopath. So switched it to another, so this problem would not appear again. But I still have no sound in my outputvideos. I give you the LOG-information, so maybe you can read something out of it.
