• Core : core.js, methods.js, Fix for #1567 - jquery-validation ignores data obj when validating, incorrectly returning previous status

  11 septembre 2015, par christopherbauer

  Core : core.js, methods.js, Fix for #1567 - jquery-validation ignores data obj when validating, incorrectly returning previous status
  This change determines if either the validated element’s value OR one of the data properties has changed before aborting the remote request. If your remote validation is skipped due to being dependent on the value of another field, this fixes that issue.

  im trying to combine set of images and audio into one video file
  but whenever I try to record a frame of audio on to the ffmpegframerecorder,it gives the error ffmpegframerecorderexception no audio output stream.can anyone please help me with this problem ?

• Importing a part of a project in Eclipse

  10 mars 2015, par Arif Gencosmanoglu

  On Eclipse, I imported FFmpeg as a project to reduce a selected video sizes for my android application. But my .apk size went up from 2MB to 24MB.

  This project includes a lot of extra properties for video editing. However I use only one single command line to reduce my video resolution. The code I added :

  LoadJNI vk = new LoadJNI();
  
                      try {
  
                          String workFolder = getApplicationContext()
  
                                  .getFilesDir().getAbsolutePath();
  
  
  
                          String[] complexCommand = {
  
                                  "ffmpeg",
  
                                  "-y",
  
                                  "-i",
  
                                  "/storage/emulated/0/DCIM/Camera/20150224_125355.mp4",
  
                                  "-strict", "experimental", "-s", "160x120",
  
                                  "-r", "25", "-vcodec", "mpeg4", "-b", "150k",
  
                                  "-ab", "48000", "-ac", "2", "-ar", "22050",
  
                                  "/storage/emulated/0/TempFolder/out.mp4" };
  
                          vk.run(complexCommand, workFolder,
  
                                  getApplicationContext());
  
  
  
                          Log.i("test", "ffmpeg4android finished successfully");
  
                      } catch (Throwable e) {
  
                          Log.e("test", "vk run exception.", e);
  
                      }

  To sum up, is there a way to import a portion of a project (as a module maybe) ? or do I have to find another method to reduce my video size ?
