• ffmpeg not working after update to Mavericks

  26 février 2015, par Hudson Buddy

  After recently updating to Mavericks 10.9.5, my installation of ffmpeg has been bugging out

  Error :

  dyld: Library not loaded: /usr/local/lib/libx264.142.dylib
  
    Referenced from: /usr/local/bin/ffmpeg
  
    Reason: image not found
  
  Trace/BPT trap: 5

  Any thoughts ? I’m not very familar with manual compiling and I installed ffmpeg through Homebrew.

  I tried uninstalling and doing :

  brew install ffmpeg --HEAD
  
  brew install ffmpeg --build-from-source

  but it spits back a ./configure error

  ==> ./configure --prefix=/usr/local/Cellar/ffmpeg/2.4.2 --enable-shared --enable-pthreads --enable-gpl --enable-version3 --enable-nonfree --enable-hardcoded-tables --enable-avresample
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from Git.  If the latest version fails, report the problem to the
  
  ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
  
  Include the log file "config.log" produced by configure as this will help
  
  solve the problem.

• Android, Splitting GIFs with FFMPEG doesnt work

  19 mars 2019, par raddeee

  I wanted to split animated gif files using FFmpeg-Android-Java, so I referenced this question Android, split gif to frames with ffmpeg
  and wrote this code.

  String path = "/storage/emulated/0/Download/mothersday-toaster.gif";
  
          String cmd[] = {"-i",path,"-vsync","0","/storage/emulated/0/Download/output$03d.png"};
  
  
  
          try {
  
              // to execute "ffmpeg -version" command you just need to pass "-version"
  
              ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
  
  
  
                  @Override
  
                  public void onStart() {}
  
  
  
                  @Override
  
                  public void onProgress(String message) {}
  
  
  
                  @Override
  
                  public void onFailure(String message) {Log.d("Q", "failed to convert");}
  
  
  
                  @Override
  
                  public void onSuccess(String message) {}
  
  
  
                  @Override
  
                  public void onFinish() {}
  
              });
  
          } catch (FFmpegCommandAlreadyRunningException e) {
  
              // Handle if FFmpeg is already running
  
          }

  Although, It always gives me the "failed to convert" log. FFMPEG is already loaded. Is there something wrong with my code ?

• FFMPEG - subtitles not showing for the full duration of video

  26 juin 2023, par Caio Maia

  I could not archive the following :

  


  

  1. Have images loaded from a textfile to create a slideshow.

  


  2. Have a background music with volume control.

  


  3. Have my voice.mp3 over the bg music.

  


  4. Have subtitles in the ass format.

  


  5. Have a text shown with drawtext in the full duration of video.

  


  6. in only one command, if possible.

  


  


  The command I tryed is :

  


  ffmpeg.exe -f concat -i images.txt -i bg_music.m4a -i voice.mp3 -filter_complex "[0:v]drawtext=fontfile='fonte.TTF':fontsize=20:fontcolor=white:text='Imagens da internet':x=w-tw-10:y=h-th-10,[0]overlay=10:10,ass=subtitles.txt[out],[1]volume=0.3[a1];[2]volume=2[a2];[a1][a2]amix=inputs=2:duration=shortest[aud]" -map "[out]" -map "[aud]":a -pix_fmt yuv420p -c:v libx264 -c:s mov_text -r 30 -y out.mp4


  


  It works but not for subtitles that are showing only after the first image of th slideshow appears.

  


  the content of images.txt is :

  


  file 'image1.png'
duration 20
file 'image2.png'
duration 5
file 'image3.png'
duration 5


  


  the content of subtitles.txt is

  


  Format: Layer, Start, End, Style, Name, MarginL, MarginR, MarginV, Effect, Text
