• How to execute command line ffmpeg commands programatically in android ?

  14 août 2013, par Md. Arafat Al Mahmud

  I have successfully built ffmpeg for android using the bambuser
  . Now I have to build a sample converter application like mp4 to 3gp. I know there are command line commands ffmpeg -i video_origine.avi video_finale.mpg. But I don't know how to execute these commands programatically. I have sample code like

  jint Java_com_example_ndklearning1_MainActivity_logFileInfo(JNIEnv * env, jobject this, jstring filename)
  
  {
  
      av_register_all();
  
  
  
      AVFormatContext *pFormatCtx;
  
      const jbyte *str;
  
      str = (*env)->GetStringUTFChars(env, filename, NULL);
  
  
  
      if(av_open_input_file(&pFormatCtx, str, NULL, 0, NULL)!=0)
  
      {
  
          LOGE("Can't open file '%s'\n", str);
  
          return 1;
  
      }
  
      else
  
      {
  
          LOGI("File was opened\n");
  
          LOGI("File '%s', Codec %s",
  
              pFormatCtx->filename,
  
              pFormatCtx->iformat->name
  
          );
  
  
  
      }
  
      return 0;
  
  }

  This code open's a file and extracts the codec information. All I want is that, to convert the opened file in a desired format. Any kind of help such as code snippet or steps to follow will be highly appreciated.

  Can ffmpeg API serve my purpose ? If there is existing API available, it will be more helpful

• Revision 5370c6f1a5 : Initialize "corrupted" to zero Because the call to vpx_codec_control at line 92

  18 mars 2015, par Johann

  Changed Paths :
   Modify /vpxdec.c

  
  
  Initialize "corrupted" to zero

  Because the call to vpx_codec_control at line 928 is now guarded by
   !frame_parallel, ’corrupted’ may not be set.

• FFMPEG works from command line but not PHP

  23 janvier 2015, par nbs189

  I have a strange situation that has just happend. FFMPEG is no longer executing from PHP but will from the command line.

  Here is exactly what the command is :

  ffmpeg -i ../../uploads/ee78d5deb564901626067cc0008456ed.mp3 -ab 96k -y ../../uploads/mp3/ee78d5deb564901626067cc0008456ed_6203688.mp3

  How it is executed in the PHP script :

  if(! exec("ffmpeg -i ".$target_path."".$hash_filename.".".$path_extension." -ab 96k -y ".$target_path."mp3/".$hash_filename."_".$session_ID.".mp3")){
  
      echo 'ffmpeg failed';
  
  }

  This command did work but not longer does. I have recently updated plesk but I highly doubt that has affected this. The only thing that I think could affect it that I have recently done is have the file upload go to a subdomain. So the directory where the file is located and stored in the command is in a directory outside the document root. However, the move_uploaded_file function works and I have altered the open_basedir in PHP ini to the webspace root.
