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.

For the original issue, "FFmpeg cannot edit existing files in-place.", that was put in place since ffmpeg needs to read the input, so it can't replace the input at the same time.
For the current issue, vorbis is not a standard audio codec for MP4, so re-encode the audio.

(Since you're writing to MP4, -bsf:v, h264_mp4toannexb is the opposite of what you want, and is not needed here)
