  On incrémente la version du plugin

• 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.

• batch store %%f as variable

  22 juin 2017, par RyanMe321

  I’ve been trying to use %%f to operate a script on each file in a directory however however when referencing it through the script the %%f and %% nf don’t seem to be working. I’ve limited programming experience I’m trying to make a more useful version of this video formatting tutorial.

  So I’d like to store %%f and %% nf as variables to reference for the rest of the script though I can’t work out how.

  @echo off
  
  set /p FORMAT="Enter File Format: "
  
  FOR %%f IN (*.%FORMAT%) DO  echo %%f
  
  set TEST=%%f
  
  echo %TEST%
  
  cmd/k

  If I could store these it would resolve my issue, however this is the longer form of what I’m trying to do, this script works if I have the user enter the file manually into a variable (%VIDEO%=%%f and % nf). Though this is far from ideal.

  @echo off
  
  set /p FORMAT="Enter File Format: "
  
  
  
  FOR %%f IN (*.%FORMAT%) DO (
  
  ::IDFILE
  
  for /F "delims=" %%I in ('C:\ffmpeg\bin\ffprobe.exe -v error -show_entries format^=filename -of default^=noprint_wrappers^=1:nokey^=1 "%%f"') do set "FILENAME=%%I"
  
  
  
  for /F "delims=" %%I in ('C:\ffmpeg\bin\ffprobe.exe -v error -select_streams v:0 -show_entries stream^=codec_name -of default^=noprint_wrappers^=1:nokey^=1 "%%f"') do set "Vcodec=%%I"
  
  
  
  for /F "delims=" %%I in ('C:\ffmpeg\bin\ffprobe.exe -v error -select_streams a:0 -show_entries stream^=codec_name -of default^=noprint_wrappers^=1:nokey^=1 "%%f"') do set "Acodec=%%I"
  
  
  
  echo %FILENAME% is using %Vcodec% and %Acodec% codecs
  
  
  
  if %Vcodec% == h264 (echo DO NOT CONVERT VIDEO) else (echo CONVERT VIDEO) 
  
  if %Acodec% == ac3 (echo DO NOT CONVERT AUDIO) else (echo CONVERT AUDIO)
