• Child Process will neither complete nor abort in Windows ?

  4 septembre 2014, par Karthikeya Vaidya

  How to make my java parent process wait till child process gets completed. I have tried with runtime.exec and with processBuilder.pb :

  String cmd = "ffmpeg -i input.vob output.mp4" 
  
  Runtime rt = Runtime.getRuntime();
  
  Process proc = rt.exec(cmd); 
  
  proc.waitFor();

  ---

  This works fine with small input file (say less than 10 Mb). If I give larger input file then program will be hanged. Output file will be partially created and file creation will be hanged and control will not return. Even proc.join(10000); did not give any useful result. Here parent process is terminating before child process (ffmpeg) gets completed.

  How to overcome this problem ?

  • How to compile ffmpeg-2.2.2 on windows with cygwin and android ndk r9c

  After a week i’m trying to compile ffmpeg for android.
  I can’t find a static build in the entire web exept for https://github.com/guardianproject/android-ffmpeg-java/tree/master/res/raw but is 0.11 version one.

  This is my build.sh

  #!/usr/bin/env bash
  
  
  
  NDK=C:/Android/android-ndk-r10
  
  SYSROOT=$NDK/platforms/android-18/arch-arm/
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/windows-x86_64
  
  
  
  function build_one
  
  {
  
  ./configure \
  
      --arch=arm \
  
      --target-os=linux \
  
      --enable-runtime-cpudetect \
  
      --enable-pic \
  
      --disable-shared \
  
      --enable-static \
  
      --extra-cflags='-march=armv6' \
  
      --extra-ldflags="$ADDI_LDFLAGS" \
  
      --enable-ffmpeg \
  
      --disable-ffplay \
  
      --disable-ffprobe \
  
      --disable-ffserver\
  
      --disable-network \
  
      --enable-cross-compile \
  
      --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  
      --sysroot=$SYSROOT \
  
      $ADDITIONAL_CONFIGURE_FLAG
  
  make clean
  
  make -j4
  
  make install
  
  }
  
  
  
  CPU=arm
  
  PREFIX=$(pwd)/android/$CPU
  
  ADDI_CFLAGS="-marm"
  
  
  
  build_one

  It seems everything works good except the compilation stopped after 4 files :

  

  It seems to stay here forever. After 4 hours nothing is moving.
  the process "make.exe (32 bit)" is running with 18% of cpu

  Any help will be precious.
  Thank u

• Deploying ffmpeg from Windows Machine using Cpanel

  24 février 2017, par BBob

  A site developed on a Windows machine using WAMP employs ffmpeg.exe to convert videos. The site will be deployed on a server running Linux. All of the links I have seen seem to require ffmpeg to be compiled and linked on the host machine. How can ffmpeg be deployed from Windows system to a Linux site thru CPanel ?
