• FFmpeg : java.lang.UnsatisfiedLinkError while calling Runnable class

  12 mars 2013, par Yuliya Tarasenko

  I need to take a picture file and an audio file and create a video.
  I know that it's possible to do with the help of

  Runtime.getRuntime().exec("ffmpeg -i image.jpeg -i audio.mp3 out.avi") 

  but only for rooted devices, so I've tried to create JNI wrapper for main() from ffmpeg.c and call it from my Activity like here : http://demo860.blogspot.com/2010/07/android-ffmpeg-dynamic-module-jni.html

  1.This code is in ffmpeg.c :

  int m_argc = 0;
  
  char *m_pargv [30];
  
  
  
  int dynamic_ffpmeg_main (int argc, char **argv);
  
  jint JNICALL Java_com_ccmedia_codec_ffmpeg_mod_1run ( JNIEnv *, jclass, jstring,     jstring );
  
  
  
  jint JNICALL Java_com_ccmedia_codec_ffmpeg_mod_1run ( JNIEnv *env, jclass class, jstring pj1, jstring pj2)
  
  {
  
      // as in http://demo860.blogspot.com/2010/07/android-ffmpeg-dynamic-module-jni.html
  
  }
  
  
  
  int dynamic_ffpmeg_main(int argc, char **argv)
  
  {
  
  // as in http://demo860.blogspot.com/2010/07/android-ffmpeg-dynamic-module-jni.html
  
  }
  
  
  
  int main(int argc, char **argv)
  
  {
  
      dynamic_ffpmeg_main ( argc, argv );
  
      return 0;
  
  }

  2.This code is in my .java :

  public class FFmpegCreator implements Runnable {
  
  
  
      static boolean m_bret = false;
  
  static String m_szconfig = " -i /sdcard/file.mpg -vcodec mpeg4 aaa.mpg";
  
  
  
  //public native String unimplementedStringFromJNI();
  
  
  
  static {
  
      try {
  
  
  
          System.out.println("[AdDBCache] Module load try ffmpeg : "
  
                  + System.getProperty("java.library.path"));
  
  
  
          // System.load("/sdcard/arm_and/bin/libffmpeg.so");
  
  
  
          System.loadLibrary("ffmpeg");
  
  
  
          System.out.println("[AdDBCache] Module load success");
  
  
  
      }
  
  
  
      catch (Exception e) {
  
  
  
          System.out.println("[AdDBCache] Module load err : "
  
                  + System.getProperty("java.library.path"));
  
  
  
      }
  
  
  
  }
  
  
  
  private static synchronized final native int Java_com_ccmedia_codec_ffmpeg_mod_1run(String name, String sztoken);
  
  
  
  public void set_config(String sz_config) {
  
  
  
      m_szconfig = sz_config;
  
  
  
  }
  
  
  
  public void run_core(String sz_file, String sz_token) {
  
  
  
      int n_stat;
  
      m_bret = false;
  
      n_stat = Java_com_ccmedia_codec_ffmpeg_mod_1run(m_szconfig, sz_token);
  
      m_bret = true;
  
  
  
  }
  
  
  
  public void run() {
  
  
  
      run_core("", "");
  
  
  
  }
  
  }

  3.And this in my Activity :

  FFmpegCreator f = new FFmpegCreator ();
  
  new Thread(f).start();

  But I have

  E/AndroidRuntime(25682): java.lang.UnsatisfiedLinkError: Java_com_ccmedia_codec_ffmpeg_mod_1run .

  And I can't understand why... FFmpeg build was successful...
  Could anyone help me, please ? I'll really appreciate if you could help me. Thank you.

• Convert avi to flowplayer compatible mp4

  19 novembre 2013, par Bill Johnston

  I'm trying to convert a .avi file to a flowplayer compatible .mp4 using the node module fluent-ffmpeg. Tried a bunch of different ways of encoding but this got the closest :

  var proc_avi = new ffmpeg({source: file})
  
  .withVideoCodec('copy')
  
  .withAudioCodec('copy')
  
  .saveToFile('output.mp4', function(stdout, stderr) {
  
      callback();
  
  });

  The video plays on flowplayer, and I can hear the audio, but the video is all white. Any idea how to encode this properly ?

• Unable to transcode video using ffmpeg transcoder

  28 octobre 2014, par user1843970

  This question may be asked in different forums but still answer is not discovered yet.

  I am trying to play *.flv using Video Module and FFMPEG Converter.
  Whenever I upload any flv Video , I get the following message :-

  PHPVideoToolkit error : Execute error. It was not possible to encode "C :\xampp\htdocs\Resonance\sites\default\files\videos\original\barsandtone_3.flv" as FFmpeg returned an error. The error is with the video codec of the input file. FFmpeg reports the error to be "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height".

  Installed Modules are :-

  Video - 7.x-2.9

  Video.js - 7.x-2.3 - Version : 4.0.3

  Video transcoder : FFmpeg / avconv : git : c2dd5a1

  JW Player

  All above are installed correctly.

  Configuration of Video Module :-

  Inside Player Tab of Video(admin/config/media/video/players), following has been configured :-

  

  A New FLV Preset has been created and added under Preset Tab of Video(admin/config/media/video/presets). Details are as Follows :-

  Preset name :- FLV Preset

  Video output extension :- FLV Flash Video

  Video codec :- H 263/H263-1996,H263+/H0-º1998/H263 Version 2(Not sure about Video Codec)

  FFmpeg video preset :- None

  Video quality :-None

  Video speed :- None

  Dimensions :- 640 X 360

  Aspect mode :- Preserve Aspect Ratio

  When I am uploading the video from content type then it extract the thumbnail as follows :-

  

  After saving the video it shows the following Mesage :-

  

  My gut feeling is that I am setting up wrong preset but I am not able to solve this problem out. Please help me as I am very close to my completion of project which would have been waste without solving the problem.

  Updated :-

  The Console message is as follows :-

  Reported errors

  PHPVideoToolkit error : Execute error. It was not possible to encode "C :\xampp\htdocs\Resonance\sites\default\files\videos\original\barsandtone_19.flv" as FFmpeg returned an error. Note, however the error was encountered on the second pass of the encoding process and the first pass appear to go fine. The error is with the video codec of the input file. FFmpeg reports the error to be "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height".
