• problems for building FFMPEG library for android on windows

  6 février 2014, par user3275506

  I am developing application for video which supports all formats.
  After much research I came to conclusion that I have to use FFMPEG library
  I have downloaded that I followed some steps I am geting unexpected end of the file.

  #!/usr/bin/env bash
  
  NDK=cygdrive/C/AndroidNDKx86/android-ndk-r9b
  
  SYSROOT=$NDK/platforms/android-18/arch-arm/
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/windows
  
  function build_one
  
  {   
  
  ./configure \
  
  --prefix=$PREFIX \
  
  --enable-shared \
  
  --disable-static \
  
  --disable-doc \
  
  --disable-ffmpeg \
  
  --disable-ffplay \
  
  --disable-ffprobe \
  
  --disable-ffserver \
  
  --disable-avdevice \
  
  --disable-doc \
  
  --disable-symver \
  
  --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi \
  
  --target-os=linux \
  
  --arch=arm \
  
  --enable-cross-compile \
  
  --sysroot=$SYSROOT \
  
  --extra-cflags="-Os -fpic $ADDI_CFLAGS" \
  
  --extra-ldflags="$ADDI_LDFLAGS" \
  
  $ADDITIONAL_CONFIGURE_FLAG
  
  
  
  make clean
  
  make -j4
  
  make install
  
  }
  
  CPU=arm
  
  PREFIX=$(pwd)/android/$CPU
  
  ADDI_CFLAGS="-marm"
  
  build_one

  Please tell me is the code wrong it gives output unexpected end of file

  I tried another one it was almost compile but during make at the end it got some errors
  Here is the updated script

  #!/bin/bash
  
      export TMPDIR=C:/cygwin/tmp
  
      ANDROID_API=android-18
  
      export ANDROID_NDK=C:/AndroidNDKx86/android-ndk-r9b

      --disable-mmx 
  
      --disable-sse 
  
      --disable-debug
  
      --disable-ssse3 
  
      --disable-indevs"     
  
  ./configure $FLAGS \
  
  --cc="${CROSS_COMPILE}gcc 
  
  --sysroot=${SYSROOT}"  \
  
  --cxx="${CROSS_COMPILE}g++ --sysroot=${SYSROOT}" \
  
  --nm="${CROSS_COMPILE}nm" \
  
  --ar="${CROSS_COMPILE}ar"
  
  make clean
  
  make -j4 || exit 1
  
  make install || exit 1

  Following is the output

• Compiling ffmpeg (-3.0) on windows 7 with nvenc

  21 février 2016, par aviyaChe

  I’m trying to compile ffmpeg (version 3.0) with the following configuration :

  ./configure --prefix=ffmpeg/ --disable-yasm --enable-nonfree --enable-nvenc

  But I get the following error :

  ERROR: nvEncodeAPI.h not found. 

  I download the latest Nvidia video SDK (version 6.0.1), but I don’t know where to copy the nvEncodeAPI.h file.

  I have the following set up :

  • cygwin64 terminal
  • Nvidia Quadro k4200, with driver 361.91
