• compile FFmpeg error on windows when run ./configure

  5 novembre 2013, par user1325717

  I want to use FFmpeg to decode mp3 and acc on android, I use android-ndk-r7 and the newest cygwin.

  I wrote a shell config.sh, which content is :

  ---

  TMPDIR=/cygdrive/c/temp
  
  
  
  PREBUILT=/cygdrive/c/android-ndk-r7/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows
  
  PLATFORM=/cygdrive/c/android-ndk-r7/platforms/android-8/arch-arm
  
  
  
  ./configure --target-os=linux --arch=arm --enable-version3 --enable-gpl --enable-nonfree --disable-stripping --disable-ffmpeg --disable-ffplay --disable-ffserver --disable-ffprobe --disable-encoders --disable-muxers --disable-devices --disable-protocols --enable-protocol=file --enable-avfilter --disable-network --disable-mpegaudio-hp --disable-avdevice --enable-cross-compile --cc=$PREBUILT/bin/arm-linux-androideabi-gcc --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- --nm=$PREBUILT/bin/arm-linux-androideabi-nm --extra-cflags="-fPIC -DANDROID" --disable-asm --enable-neon --enable-armv5te --extra-ldflags="-Wl,-T,$PREBUILT/arm-eabi/lib/ldscripts/armelf_linux_eabi.x -Wl,-rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -nostdlib $PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/crtbegin.o $PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/crtend.o -lc -lm -ldl"

  I open cmd and do bash to open cygwin shell, then do ./config, the problem is appeared :
  "/cygdrive/c/android-ndk-r7/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/arm-linux-androideabi-gcc is unable to create an executable file..."

  the config.log is :

  I don't know what is happened, is there someone who know what is happened, thanks.

• Java exec doesn't work in 64 bit Windows

  4 juillet 2012, par dinesh707

  I am trying to run the following ffmpeg command using java exec call. It works well in a 32bit computer but in 64 bit computer it doesn't work. Can someone please help me to solve this issue.

  When I try the same command in command prompt as admin it works. Here the target is to create a video file in the tomcat. But when I try as a normal user in commandprompt it didn't work. Can this be an issue with tomcat privileges ?
