[FFmpeg-user] How to resolve “ERROR: libx264 not found”?

Hi,

I needed to install ffmpeg with libx264 support for enabling H.264 encoding
. I installed libx264 successfully using the below script with toolchains
available in android-ndk-r9d .

 #!/bin/bash
 NDK=~/android-ndk-r9d
 SYSROOT=$NDK/platforms/android-8/arch-arm/
 TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64
 function build_one
 {
 ./configure \
 --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
 --sysroot="$SYSROOT" \
 --host=arm-linux \
 --enable-pic \
 --enable-shared \
 --disable-cli
 make clean
 make
 make install
 }
 build_one

Now I wanted to build ffmpeg with libx264 support .  I used the below
script with --enable-libx264 , --enable-nonfree , --enable-gpl options
as in the below script .

SYSROOT=$NDK/platforms/android-8/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64function
build_one{./configure \--prefix=$PREFIX \--enable-shared
\--enable-nonfree \--enable-gpl \--enable-libx264 \--disable-doc
\--disable-ffmpeg \--disable-ffplay \--disable-ffprobe
\--disable-ffserver \--disable-avdevice \--disable-doc
\--disable-symver
\--cross-prefix=$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" \
$ADDITIONAL_CONFIGURE_FLAG
make clean
make
make install}
CPU=arm
PREFIX=$(pwd)/android/$CPU
ADDI_CFLAGS="-marm"
build_one

But when I run the script I'm getting error "ERROR: libx264 not found" .

I suppose ffmpeg is not able to figure out the installed location of
libx264 . After libx264 installation I have libx264.so file in
/usr/local/lib executable at /usr/local/bin and header files at
/usr/local/include directories .

What all changes do I need to make to the ffmpeg build script in-order to
make it detect libx264?
