• 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.

  Bounty

  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.

• Anomalie #4108 (Fermé) : Critère IN et #ENV

  4 mars 2018, par Maïeul Rouquette

  Du fait que SPIP traite les #ENV comme des chaînes, ont ne peut pas utiliser un #ENV pour définir un IN sous forme de liste séparées par virgule.

  #ID_ARTICLE
  
  

  Sur http://astro.dev/?page=toto&ids_article=1,105
  donne
  

  SELECT articles.id_article, articles.lang, articles.titre
  FROM central_articles AS `articles`
  WHERE (articles.statut = ’publie’)
      AND ((articles.id_article  IN (’1,105’)))
  ORDER BY FIELD(articles.id_article,’1,105’)
  

  et pas

  SELECT articles.id_article, articles.lang, articles.titre
  FROM central_articles AS `articles`
  WHERE (articles.statut = ’publie’)
      AND ((articles.id_article  IN (1,105)))
  ORDER BY FIELD(articles.id_article,1,105)
  

  comme on pourrait souhaiter.

• gdb and ffmpeg compilation

  6 octobre 2019, par toutou0091

  I installed ffmpeg using the instructions of the web site ffmpeg : http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide, compilation works fine, they generates a file "ffmpeg_201207131721-git-1_amd64.deb " then, I excute

  sudo dpkg-i ffmpeg_201207131721-git-1_amd64.deb

  When I excute the command

  ffmpeg -i -f toto.flv mp3-vn-acodec copy new_video.mp3

  file "new_video. mp3" is well established. I would like to know what is the command "gdb" that I could use to find the file that have been consulted when i run the command ffmpeg -i -f toto.flv mp3-vn-acodec copy new_video.mp3

  Thank you in advance
