带有NDK r10d的Android的FFMPEG 2.5.4构建

Question

I'm trying to build FFmpeg for android following this tuto: http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/

I'm using:

• NDK r10d
• FFMPEG 2.5.4

I have tried to build on MacOs and Ubuntu and I get the same error when I execute ./build_android.sh:

`Creating config.mak, config.h, and doc/config.texi...
./build_android.sh: line 16: --prefix=/Users/jesusmartin92/Documents/android-ndk-r10d/sources/ffmpeg-2.5.4/android/arm: No such file or directory

./build_android.sh: line 48: --extra-cflags=-Os -fpic -marm: command not found
./build_android.sh: line 50: --extra-ldflags=: command not found`

It's like the script doesn't find the ndk folder, but I checked and the path is OK. The script "build_android.sh" is in the ffmpeg folder. This is the content of it:

#!/bin/bash
NDK=/Users/jesusmartin92/Documents/android-ndk-r10d
SYSROOT=$NDK/platforms/android-9/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64
function build_one
{
./configure \
    --prefix=$PREFIX \
    --enable-shared \
    --disable-static \
    --disable-doc \
    --disable-ffmpeg \
    --disable-ffplay \
    --disable-ffprobe \
    --disable-ffserver \
    --disable-avdevice \
    --disable-doc \
    --disable-symver \
    --cross-prefix=$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

I'm very stuck, so any idea will be well received.

Thanks

Answer 1

Finally, I solved my problem. I put the configure command in one line and it worked!! I don't know why it was failing...

Anyway, Now I'm using this project ( https://github.com/hiteshsondhi88/ffmpeg-android-java ) so, I don't have to compile anything. I think it's the easy way to use FFMPEG in our Android applications.

EDIT: I finished my project. You can check my work on GitHub: https://github.com/JesusMartinAlonso/Video4Share

Try this:

put the bin file of the ndk in the same directory of your ndk.

Enter the command prompt

go to the directory using the command prompt.

Enter: chmod a+x android-ndk-r10d-linux-x86_64.bin then: ./android-ndk-r10d-linux-x86_64.bin

(assuming you have a 64 bit machine)

now you have the ndk.

go to the ndk folder then sources and extract ffmpeg-2.6 there

create a file called build_android.sh containing:

#!/bin/bash

# Usage:
# put this script in top of FFmpeg source tree
# ./build_android
# It generates binary for following architectures:
# ARMv6 
# ARMv6+VFP 
# ARMv7+VFPv3-d16 (Tegra2)

# 1. Feel free to change ./configure parameters for more features
# 2. To adapt other ARM variants

enter command prompt and go to the ffmpeg-2.6 folder then enter:

sudo chmod 755 build_android.sh
