[FFmpeg-devel] How to build FFmpeg to support NEON optimization in Android

[lee dallas]

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 \
