I'm found way to porting xvid on android
But its only a libxvidcore.so
You must write an application to use it, but it's not so hard.
export _XXCFLAGS=" -mcpu=cortex-a8 -march=armv7-a -mtune=cortex-a8 -mfpu=vfpv3 -O3 -Os" (if you have Motorola Milestone/Droid or other device with TI OMAP3430)
export _XXCFLAGS=" -march=armv6j -mtune=arm1136jf-s -O3 -Os" (if you have HTC Hero or other device with Quallcomm MSM 7200A)
or others flags for your device, based on information of his chip.
also you must have cross-toolchain to build it.
cd src/build/generic
./configure --host=arm --target=arm-android-linux-uclibcgnueabi CC="arm-android-linux-uclibcgnueabi-gcc" \
CXX="arm-android-linux-uclibcgnueabi-g++" STRIP="arm-android-linux-uclibcgnueabi-strip" \
AR="arm-android-linux-uclibcgnueabi-ar" AS="arm-android-linux-uclibcgnueabi-as" \
LD="arm-android-linux-uclibcgnueabi-ld" RANLIB="arm-android-linux-uclibcgnueabi-ranlib" \
OBJDUMP="arm-android-linux-uclibcgnueabi-objdump" NM="arm-android-linux-uclibcgnueabi-nm" \
CROSS_COMPILE="arm-android-linux-uclibcgnueabi-" \
CFLAGS=" -nodefaultlibs -nostdlib -fPIC $_XXFLAGS" \
CXXFLAGS=" -nodefaultlibs -nostdlib -fPIC $_XXFLAGS" \
LDFLAGS=" -fPIC -static -s -L$HOME/build/cross/sys-root/usr/lib -lm -lc" --prefix="$HOME/build/cross/sys-root/usr"
cd =build
rm-android-linux-uclibcgnueabi-ld -shared -s -o libxvidcore.so -whole-archive libxvidcore.a
libxvidcore.so - shared library without any dependencies (only kernel!, not libc)
-------------------------------------------------------------------------------------------------------
Inform for toolchain
Based on crosstol-ng with gnu gcc + uClibc + kernel sources from your device vendor.
If needed i can post advanced information with sample configs. But i'm have very bad memory - so if you needed advanced howto - please send direct (private) message.
