Hi all,
I've been trying to build FFmpeg to support NEON optimization for Android
for days without success.
Anyone has succeeded to build that? Would you please share the config.sh?
Here is mine:
#!/bin/bash
PREBUILT=/home/kenny/android-ndk-r4b/build/prebuilt/linux-x86/arm-eabi-4.4.0
PLATFORM=/home/kenn/android-ndk-r4b/build/platforms/android-8/arch-arm
./configure --target-os=linux \
--disable-static \
--enable-shared \
--disable-doc \
--arch=arm \
--cpu=cortex-a8 \
--disable-stripping \
--disable-ffmpeg \
--disable-ffplay \
--disable-ffserver \
--disable-ffprobe \
--disable-encoders \
--disable-muxers \
--disable-devices \
--disable-avformat \
--disable-swscale \
--disable-filters \
--disable-protocols \
--disable-avfilter \
--disable-network \
--disable-mpegaudio-hp \

--enable-cross-compile \
--cc=$PREBUILT/bin/arm-eabi-gcc \
--cross-prefix=$PREBUILT/bin/arm-eabi- \
--nm=$PREBUILT/bin/arm-eabi-nm \
--extra-cflags="-fPIC -DANDROID -mfpu=neon -mfloat-abi=softfp" \
--disable-armv5te \
--disable-armv6 \
--disable-armv6t2 \
--disable-armvfp \
--enable-neon \
--extra-ldflags="-Wl,-T,$PREBUILT/arm-eabi/lib/ldscripts/armelf.x

$PREBUILT/lib/gcc/arm-eabi/4.4.0/crtbegin.o
$PREBUILT/lib/gcc/arm-eabi/4.4.0/crtend.o -lc -lm -ldl"
