• PHP exec() with mixed quotes

  27 juin 2016, par user1661677

  I’m trying to run the following ffmpeg command with PHP’s exec(), but because of the need for double-quotes and single-quotes, exec() is failing.

  /usr/bin/ffmpeg -loop 1 -i /var/www/html/data/photos/576c2ecf766fe.png -vf "zoompan=z='if(lte(zoom,1.0),1.5,max(1.001,zoom-0.0015))':d=125" -c:v libx264 -pix_fmt yuv420p -t 5 -s hd1080 -crf 17 /var/www/html/ffmpeg/zoomout.mp4

  How can I run this script via PHP ?

  Thank you

• FFmpeg - cannot find ExecuteBinaryResponseHandler - Android/Java

  20 juillet 2018, par pudility

  I am trying to make a module for react-native that will change a video into a gif. I have little to no experience with android studios/java, but I would love to learn more ! I am using this library to convert the video to a gif. Here is my code :

  package com.reactlibrary;
  
  
  
  import android.widget.Toast;
  
  import com.facebook.react.bridge.ReactApplicationContext;
  
  import com.facebook.react.bridge.ReactContextBaseJavaModule;
  
  import com.facebook.react.bridge.ReactMethod;
  
  import com.github.hiteshsondhi88.libffmpeg.FFmpeg;
  
  
  
  public class RNGifMakerModule extends ReactContextBaseJavaModule {
  
  
  
    private final ReactApplicationContext reactContext;
  
  
  
    public RNGifMakerModule(ReactApplicationContext reactContext) {
  
      super(reactContext);
  
      this.reactContext = reactContext;
  
    }
  
  
  
    @Override
  
    public String getName() {
  
      return "RNGifMakerModule";
  
    }
  
  
  
    @ReactMethod
  
    public void alert(String message) {
  
        Toast.makeText(getReactApplicationContext(), "Error", Toast.LENGTH_LONG).show();
  
        String[] cmd = {"-i"
  
                , message
  
                , "Image.gif"};
  
        conversion(cmd);
  
    }
  
  
  
    public void conversion(String[] cmd) {
  
  
  
      FFmpeg ffmpeg = FFmpeg.getInstance(this.reactContext);
  
  
  
      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) {
  
          }
  
  
  
          @Override
  
          public void onSuccess(String message) {
  
          }
  
  
  
          @Override
  
          public void onFinish() {
  
          }
  
        });
  
      } catch (FFmpegCommandAlreadyRunningException e) {
  
        // Handle if FFmpeg is already running
  
        e.printStackTrace();
  
      }
  
    }
  
  }

  And I get this error :

  Error:(43, 31) error: cannot find symbol class ExecuteBinaryResponseHandler

  This seems odd to be, because in the documentation for ffmpeg-android-java it says to use almost exactly the same code.

  The bounty will be awarded to you if you can find a way to convert a video.mp4 into a gif. You do not necessarily have to use FFmpeg, but your solution has to work with java/android studios.
