  • 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.

  • Statically built FFMPEG binary segmentation fault

    12 février 2020, par stevendesu

    It included several filters which I won’t ever need or use, but these filters are pulled in automatically if you don’t specify --disable-avfilter, and specifying --disable-avfilter prevents the ffmpeg binary from being produced. So I’m stuck with those.

    Using these parameters and then running make, I received a binary that was about 5.9 MB in size and looked right :

    $> ldd ffmpeg
    
        not a dynamic executable

    But when I try to run it :

    $> ./ffmpeg -version
    
Segmentation fault

    Using valgrind to try and inspect the cause of the segmentation fault :

    $> valgrind ./ffmpeg -version
    
.... lots of stuff ...

    Attempting to access memory at location 0x0 sounds like trying to follow a null pointer. But I’m not sure how to fix this.

    gdb backtrace

    When I first ran gdb ./ffmpeg gdb immediately gave me a segmentation fault and I wasn’t kicked into the gdb REPL, so I couldn’t investigate

    After rebuilding ffmpeg I was able to get in this time :

    $> gdb ./ffmpeg

    I tried grep’ing the code base for __register_frame_info_bases and found nothing. So I’m not really sure where to go from here

    A fix, but not an explanation

    By randomly removing configuration parameters and rebuilding I discovered that --disable-pthreads was causing the segmentation fault. When I remove this, ffmpeg runs just fine

    I don’t know why this is the case, though. Why would they make it possible to remove something that you need to run ?

    lavfi/vf_drawtext : fix memory management when destroying font face

    Ref https://trac.ffmpeg.org/ticket/11152
    

    According to harfbuzz docs, hb_ft_font_set_funcs() does not need to be
    
called, as, quoted :
    

    ```
    
An #hb_font_t object created with hb_ft_font_create()
    
is preconfigured for FreeType font functions and does not
    
require this function to be used.
    
```
    

    Using this function seems to cause memory management issues between
    
harfbuzz and freetype, and could be eliminated.
    

    This commit also call hb_ft_font_changed() when the underlying FC_Face
    
changes size, as stated on hardbuzz :
    

    ```
    
HarfBuzz also provides a utility function called hb_ft_font_changed() that you should call
    
whenever you have altered the properties of your underlying FT_Face, as well as a hb_ft_get_face()
    
that you can call on an hb_font_t font object to fetch its underlying FT_Face.
    
```
    

    Finally, the execution order between hb_font_destroy() and
    
hb_buffer_destroy() is flipped to match the order of creation of
    
the respective objects.
