• from unix ffmpeg bash pipe to windows ''universe"

  25 septembre 2017, par Macheneso R.

  I am trying to "translate" some script from bash to windows powershell

  I tried to pass the simplest

   ffmpeg -i video.mp4 -vn -sn -map 0:a:0 -f flac - | ffmpeg -i - -c:a aac oiji.m4a

  the result is a failure

  using -f wav - another failure

  there is a way to make it work ?

  thank you

• How to install PHP FFMPEG on windows 10 64 Bit

  7 septembre 2017, par PlanetHackers

  I want to install the PHP FFMPEG on my system. My system configuration is :

  OS : Windows 10 64 Bit
  XAMPP v3.2.2
  PHP v7.0.15

  I found many tutorial but nothing found working. May be due to 64 bit system. I wanted to add a watermark to a video through PHP. That’s why I need the ffmpeg extension. I also tried through Composer but did not get success.

• Can I Config FFMEG-2.4.3 to use in android windows 64 ?

  13 novembre 2014, par Ngo Ky

  I want to build ffmpeg-2.4.3 (lastest c lib) to use it on android for managing video.
  my OS is windows 7 Utimate x64
  cywin64 in directory : C :/cywin64/ have make installed.
  NDK in directory : D :\solfware\Programming\android-ndk-r10c

  i follow toturial form : http://www.roman10.net/how-to-build-ffmpeg-for-android/comment-page-1/
  my project struture like :

  

  i create build_android.sh like roman10 as following code :

  # ARMv7+Neon (Cortex-A8)
  
  # Customizing:
  
  # 1. Feel free to change ./configure parameters for more features
  
  # 2. To adapt other ARM variants
  
  # set $CPU and $OPTIMIZE_CFLAGS 
  
  # call build_one

  i have set my path like above
  I built it in Eclipse Everything is ok. but when i ran it in Android it crashed Unfortunately.
  I found the errors in Logcat monitor :

  E/AndroidRuntime(1931) : java.lang.UnsatisfiedLinkError : Couldn’t load avcodec-55 from loader dalvik.system.PathClassLoader[DexPathList [1]] : findLibrary returned null

  E/AndroidRuntime(1931) : at java.lang.Runtime.loadLibrary(Runtime.java:358)

  In my activity i just call add Library from C preference like :

  static {
  
          //System.loadLibrary("avutil-52");
  
          System.loadLibrary("avcodec-55");
  
          System.loadLibrary("avformat-55");
  
          System.loadLibrary("swscale-2");
  
          System.loadLibrary("tutorial02");
  
      }

  i check in DDMS in app-lib there is no existing Library in there.

  The question is : Can i can compile the ffmpeg on windows ?
  if ok. how can i config build_android.sh to point to Android $PREBUILT

  PLATFORM=$NDK/platforms/android-8/arch-arm/
  
      PREBUILT=$NDK/prebuilt/windows-x86_64
  
      function build_one
  
      {
  
      ./configure --target-os=linux \
  
          --prefix=$PREFIX \
  
          --enable-cross-compile \
  
          --extra-libs="-lgcc" \
  
          --arch=arm \
  
          --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
  
          --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
  
          --nm=$PREBUILT/bin/arm-linux-androideabi-nm \
  
          --sysroot=$PLATFORM \
  
          --extra-cflags=" -O3 -fpic -DANDROID -DHAVE_SYS_UIO_H=1 -Dipv6mr_interface=ipv6mr_ifindex -fasm -Wno-psabi -fno-short-enums -fno-strict-aliasing -finline-limit=300 $OPTIMIZE_CFLAGS " \
  
          --disable-shared \

  i found that in $NDK/prebuilt/windows-x86_64/bin did not exist arm-linux-androideabi-gcc\
  How can i config to be suitable to run on windows ?

  Thank in advanced
