The latest version of FFMPEGis 3.1.1, Just released before 12 days. So i think there is no readily available demo like this oldone.

最新版本FFMPEG是3.1.1，12天前刚刚发布。所以我认为没有像这个旧的那样现成的演示。

We need to build the FFMPEGlibrary on our own. Some questions i found just pasting here that might help you. (Not tested)

我们需要自己构建FFMPEG库。我发现刚刚粘贴在这里的一些问题可能对您有所帮助。（未测试）

How to Build FFmpeg for Android

如何为 Android 构建 FFmpeg

You need to compile it on your own the by downloading Android NDK& Latest Version of FFMPEG.

您需要通过下载Android NDK和最新版本的FFMPEG.

One tutorial is also there : How to Build FFmpeg for Android. This is quite old so you just need to change the versions mentioned here. For FFMPEGit will be 3.1.1& NDK it will be r12b.

还有一个教程：如何为 Android 构建 FFmpeg。这是很旧的所以你只需要改变这里提到的版本。因为FFMPEG它将是3.1.1& NDK 它将是r12b.

Building FFMPEGwith NDK r12b:

建立FFMPEG与NDK R12B：

Download Android NDK: The latest version of Android NDK can be downloaded at Android NDK website. At the time of writing this answer, the newest version is NDK r12. simply decompress the archive
Download ffmpeg source code: FFMPEG source code can be downloaded from the ffmpeg website. The latest stable release is 3.1.1 (at the time of writing). Download the source code and decompress it to $NDK/sources folder.

Update configure file :Open ffmpeg-3.1.1/configure file with a text editor, and locate the following lines.

SLIBNAME_WITH_MAJOR='$(SLIBNAME).$(LIBMAJOR)'
LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"'
SLIB_INSTALL_NAME='$(SLIBNAME_WITH_VERSION)'
SLIB_INSTALL_LINKS='$(SLIBNAME_WITH_MAJOR) $(SLIBNAME)'

This cause ffmpeg shared libraries to be compiled to libavcodec.so. (e.g. libavcodec.so.55), which is not compatible with Android build system. Therefore we'll need to replace the above lines with the following lines.

SLIBNAME_WITH_MAJOR='$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)'
LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"'
SLIB_INSTALL_NAME='$(SLIBNAME_WITH_MAJOR)'
SLIB_INSTALL_LINKS='$(SLIBNAME)

Build ffmpeg :Copy the following text to a text editor and save it as build_android.sh in ffmpeg_3.1.1 folder.

    #!/bin/bash
    NDK=$HOME/Desktop/adt/android-ndk-r9
    SYSROOT=$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

Once the file is saved, go to the directory where this file lies & execute the command below,

sudo chmod +x build_android.sh

Then execute the script by the command,

./build_android.sh

Build Output :The build can take a while to finish depending on your computer speed. Once it's done, you should be able to find a folder $NDK/sources/ffmpeg-3.1.1/android, which contains arm/lib and arm/include folders.
Make ffmpeg Libraries available for Your Projects

下载Android NDK：最新版本的Android NDK 可在Android NDK 网站下载。在撰写此答案时，最新版本是 NDK r12。只需解压缩存档
下载 ffmpeg 源代码：FFMPEG 源代码可从ffmpeg 网站下载。最新的稳定版本是 3.1.1（在撰写本文时）。下载源代码并解压到 $NDK/sources 文件夹。

更新配置文件：用文本编辑器打开 ffmpeg-3.1.1/configure 文件，找到以下几行。

SLIBNAME_WITH_MAJOR='$(SLIBNAME).$(LIBMAJOR)'
LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"'
SLIB_INSTALL_NAME='$(SLIBNAME_WITH_VERSION)'
SLIB_INSTALL_LINKS='$(SLIBNAME_WITH_MAJOR) $(SLIBNAME)'

这会导致 ffmpeg 共享库被编译为 libavcodec.so。（例如 libavcodec.so.55），它与 Android 构建系统不兼容。因此，我们需要用以下几行替换以上几行。

SLIBNAME_WITH_MAJOR='$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)'
LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"'
SLIB_INSTALL_NAME='$(SLIBNAME_WITH_MAJOR)'
SLIB_INSTALL_LINKS='$(SLIBNAME)

构建 ffmpeg ：将以下文本复制到文本编辑器，并将其另存为 ffmpeg_3.1.1 文件夹中的 build_android.sh。

    #!/bin/bash
    NDK=$HOME/Desktop/adt/android-ndk-r9
    SYSROOT=$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

保存文件后，转到该文件所在的目录并执行以下命令，

sudo chmod +x build_android.sh

然后通过命令执行脚本，

./build_android.sh

构建输出：构建可能需要一段时间才能完成，具体取决于您的计算机速度。完成后，您应该能够找到一个文件夹 $NDK/sources/ffmpeg-3.1.1/android，其中包含 arm/lib 和 arm/include 文件夹。
使 ffmpeg 库可用于您的项目

Steps above are fully tested and i performed them on my machine and the build was successful. For writing this answer i have took the reference from this article How to Build ffmpeg with NDK r9but as it was for older version i have made some corrections on my own.

上面的步骤已经过全面测试，我在我的机器上执行了它们并且构建成功。为了写这个答案，我参考了这篇文章如何使用 NDK r9 构建 ffmpeg，但对于旧版本，我自己做了一些更正。

Open for asking any doubts.

开放询问任何疑问。

The library called FFmpeg4Android and can be found here at WarZone.

名为 FFmpeg4Android 的库可以在 WarZone 中找到。

I know the title says it from December 6, 2011 but i've tested and worked with it and it all runs smoothly. You haven't mentioned what's your exact need with this library but you could read about the ffmpeg abilities at the official site.

我知道标题说的是 2011 年 12 月 6 日，但我已经对其进行了测试和使用，并且一切运行顺利。您还没有提到您对这个库的确切需求，但您可以在官方网站上阅读有关 ffmpeg 功能的信息。

The FFmpeg4Android has an example project that can be a great reference, and also their support is immediate and clear.

FFmpeg4Android 有一个示例项目，可以作为一个很好的参考，而且它们的支持是直接和明确的。

The commands are running according to your string input, e.g:

这些命令根据您的字符串输入运行，例如：

ffmpeg -y -i /sdcard/videokit/in.mp4 -strict experimental -s 160x120 -r 25 -vcodec mpeg4 -b 150k -ab 48000 -ac 2 -ar 22050 /sdcard/videokit/out.mp4
