• 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.

• How to select compile parameter with custom need？

  19 février 2019, par Shucheng

  I need to compile a static FFmpeg on macOS and add this build to a Xcode project. If I download a full version from official website that is work. But this version size is huge, and I just need a few format to convert. So I need to compile by myself.

  I’ve tired to compile and it’s worked. But I am not sure how to select compile parameter.

  For instance, I need to convert : ogg,flac,opus,webm files to mp3 file with the minimum size. And my compile parameter :

    ./configure --enable-ffmpeg --enable-small  --enable-static --enable-protocol=file,http,https --enable-libvorbis \
  
    --enable-libopus --disable-ffplay --disable-ffprobe --enable-demuxer=mp3,mp4,webm_dash_manifest,opus,flac,ogg \
  
    --enable-decoder=mp3*,vp*,mpeg4*,opus,flac --enable-libmp3lame  --disable-autodetect --disable-network --enable-pthreads

  But it seems not to work, I can’t convert files. Error reason is dyld: Library not loaded: /usr/local/opt/lame/lib/libmp3lame.0.dylib.But I used parameter --enable-static.

  So what should I do ? If I need to support a format to convert, I need to care about which respect ? Thanks

• 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 ?
