  • 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 :

    tmp/render_2.mp4: Invalid data found when processing input

    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.

  • FFmpeg scaling issue

    12 janvier 2018, par DonX

    I am trying to down scale a video from 607x1080 to 440 width with the height automatically being calculated using the following command. It does scale the video but not to the specified dimension. The video is scaled to 216x384 even though the output below indicates 440x384.

    ffmpeg -i video.mp4 -vf scale=440:-2 -c:v libx264 -c:a aac -y video-out.mp4

    The output is as follows :

    I did some searching and learned this may be an issue scaling with libx264 codec and the input width being an odd number ? If so, is there a workaround so get the video to scale to the specified size ? Thank you.

  • Recording screencast using ffmpeg produces audio that is out of sync with the video

    7 décembre 2014, par AgilE

    I’m on Fedora 20. I got it pre-compiled from the repo.

    I use the follow command to record screencasts :

    ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s 1366x768 -i :0.0 -acodec pcm_s16le -vcodec libx264 -preset ultrafast -crf 0 -threads 0 filename.mkv

    The audio is perfectly synced with the video at the beginning. However, as the video progresses, the audio starts lagging behind severely (say a lag of more than 4 seconds). I’ve included a sample output that ffmpeg shows while recording a video.
