  • ffmpeg video won't play in certain players

    25 janvier 2021, par Thomas Tiotto

    I'm generating a video in /folder/ from a stack of images in /folder/tmp/ using the following command :

    


     ffmpeg -pattern_type glob -i 'folder/tmp/*.png' -c:v libx264 -preset veryslow -crf 17 -tune stillimage -y -pix_fmt yuv420p folder/weight_evolution.mp4


    


    but my video won't play in, for example, QuickTime ("The file isn’t compatible with QuickTime Player.") and even sending it in Telegram gives really strange results. The video plays fine in IINA and VLC.

    


    As you can see, this is what is encoded by Telegram :

    


    Telegram encoding

    


    and this is what the video should look like :

    


    Original video

    


    The output of the command is :

    


    ffmpeg -pattern_type glob -i 'tmp/*.png' -c:v libx264 -preset veryslow -crf 17 -tune stillimage -y -pix_fmt yuv420p weight_evolution.mp4

  • 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) {

    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.

    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.
