• Using ffmpeg to split MP3 file to multiple equally sound length files

  11 septembre 2019, par daliaessam

  How to use the command line tool ffmpeg on Windows to split a sound file to multiple sound files without changing the sound properties same everything each one is fixed 30 seconds length. I got this manual example from here :

  ffmpeg -i long.mp3 -acodec copy -ss 00:00:00 -t 00:00:30 half1.mp3
  
  ffmpeg -i long.mp3 -acodec copy -ss 00:00:30 -t 00:00:30 half2.mp3

  But is there a way to tell it to split the input file to equally sound files each one is 30 seconds and the last one is the remaining what ever length.

• config.h : No such file or directory after importing eclipse ndk project in android studio

  25 mai 2016, par Alin

  I have a working project in eclipse that uses ffmpeg. The implementation is like in this tutorial : http://enoent.fr/blog/2014/06/20/compile-ffmpeg-for-android/

  After importing the project into Android Studio 2.1 the only error I got was related to

  android.useDeprecatedNdk=true in my gradle.properties

  When I try to run the project I get the following error :

   config.h: No such file or directory

  on ffmpeg.h

  #ifndef FFMPEG_H
  
  #define FFMPEG_H
  
  
  
  #include "config.h"
  
  
  
  #include 
  
  #include 
  
  #include 
  
  ....

  My build.gradle has :

  ndk {
  
              moduleName "videokit"
  
          }

  What should I do to fix the problem ?

  LE : Possible solution :
   I created the jniLibs folder and added the .so file from eclipse lib’s folder and it seem to work...

  <BtbN> andrey_turkin, ubitux, yeah, I like the current state of nvenc in
  
  ffmpeg, I think most remaining differences should be merged on the libav
  
  side of things. At least I’m not aware of anything that’s missing in
  
  ffmpeg.
