  • FFMPEG images to video outputs junk

    15 décembre 2019, par GreatCorn

    I’m very new to using FFMPEG and I’m trying to make an image sequence into a video. However, none of my attempts were succesful. I first tried 825x480 .pngs which resulted in video output and then 512x512 .jpgs, pretty much the same result. I tried a few codes like ffmpeg -framerate 24 -i img%03d.png output.mp4, ffmpeg -r 1/5 -framerate 24 -i img%03d.png -c:v libx264 -vf -pix_fmt yuv420p output.mp4 and etc. I just don’t really understand what I’m supposed to do to prevent this.

  • FFMPEG does not produce output a valid mp4 when called from Java

    13 décembre 2019, par VincBreaker

    I am merging an image with an audio file into a mp4-video using the ffmpeg-command :

    ffmpeg -y -r 30 -loop 1 -i <path></path>to/image.png> -i <path></path>to/audio.aac> -shortest -acodec copy -vcodec libx264 <path></path>to/output.mp4>

    To call this command from Java I’m using this code :

    ProcessBuilder builder = new ProcessBuilder("ffmpeg", "-y", "-r",
    
                    String.valueOf(generalConfig.getOutputFPS()), "-loop", "1", "-i", pictureFile,
    
                    "-i", transspoken.getVoiceFile(), "-shortest", "-acodec", "copy", "-vcodec", "libx264",
    
                    snippetOut);
    
builder.redirectOutput(new File(getTMPName() + ".txt"));
    
builder.redirectError(new File(getTMPName() + ".txt"));
    
builder.redirectErrorStream(true);
    

    
LogUtils.debug("FFMPEG-Render", String.join(" ", builder.command()));
    
try {
    
    Process p = builder.start();
    
    p.waitFor();
    
} catch (IOException | InterruptedException e) {
    
    e.printStackTrace();
    
}

    This code runs without problem on my local machine running Ubuntu 18.04 Desktop and OpenJDK 11.0.4. However, when run on a Ubuntu 18.04 Server droplet, running the same OpenJDK-Version, the code results in a corrupted output. Strangely, there is absolutely no problem when I ssh into the server and call exactly the same command to generate the mp4 file. So I am in a the really strange situation where :

    1. The command works fine when called automatically on my local machine.
    2. The command works fine when called manually on the server.
    3. The command does not work when called automatically on the server.

    Output of the automated FFMPEG call on the server :

    At first I thought that the java program is not properly waiting for FFMpeg to finish thereby causing the corrupted output but some time measurements made me somewhat confident that that is not the cause of this bug.
