RxFFmpeg

RxFFmpeg 是基于 ( FFmpeg 4.0 + X264 + mp3lame + fdk-aac ) 编译的适用于 Android 平台的音视频编辑、视频剪辑的快速处理框架，包含以下功能（视频拼接，转码，压缩，裁剪，片头片尾，分离音视频，变速，添加静态贴纸和gif动态贴纸，添加字幕，添加滤镜，添加背景音乐，加速减速视频，倒放音视频，音频裁剪，变声，混音，图片合成视频，视频解码图片等主流特色功能……

编译环节

编译环境

  • win10 + ubuntu 16.04 + gcc + make

主要依赖以下库进行编译

库名 版本 下载地址 FFmpeg 4.0 http://ffmpeg.org/releases/ffmpeg-4.0.tar.bz2 X264 x264-snapshot-20180212-2245-stable http://download.videolan.org/x264/snapshots/x264-snapshot-20180212-2245-stable.tar.bz2 mp3lame 3.100 https://jaist.dl.sourceforge.net/project/lame/lame/3.100/lame-3.100.tar.gz fdk-aac 0.1.6 https://jaist.dl.sourceforge.net/project/opencore-amr/fdk-aac/fdk-aac-0.1.6.tar.gz ndk android-ndk-r14b-linux-x86_64 https://dl.google.com/android/repository/android-ndk-r14b-linux-x86_64.zip

特色功能

  • 支持任何FFmpeg命令执行

  • 支持FFmpeg命令执行进度回调

  • 支持中断FFmpeg命令

  • 支持同步/异步执行

  • 支持开启/关闭 debug 模式

  • 支持硬件加速，使编解码处理更快

  • 代码封装成SDK的方式，方便依赖使用

  • 支持把FFmpeg的各子模块libavutil libavcodec libavformat libavdevice libavfilter libswscale libswresample libpostproc 最终打包成一个libffmpeg-core.so核心库方便依赖使用，无需导入七八个so库

  • 支持libx264编码库，可以使压缩后的视频体积变的极小，清晰度还保持着很高清，简单的压缩命令: ffmpeg -y -i /storage/emulated/0/1/input.mp4 -b 2097k -r 30 -vcodec libx264 -preset superfast /storage/emulated/0/1/result.mp4

  • 支持添加mp3、aac、wav等主流格式的背景音乐

使用方式

  • 开启/关闭 debug 模式，建议在 Application 初始化调用
RxFFmpegInvoke.getInstance().setDebug(true);
  • FFmpeg 命令执行 (RxJava2优雅的调用) 推荐这种
String text = "ffmpeg -y -i /storage/emulated/0/1/input.mp4 -vf boxblur=25:5 -preset superfast /storage/emulated/0/1/result.mp4";

String[] commands = text.split(" ");

RxFFmpegInvoke.getInstance().runCommandRxJava(commands).subscribe(new Subscriber<Integer>() {

            @Override
            public void onSubscribe(Subscription s) {
                s.request(Long.MAX_VALUE);
            }

            @Override
            public void onNext(Integer progress) {
                if (progress == -100) {//取消状态
                    if (mProgressDialog != null)
                        mProgressDialog.cancel();
                    showDialog("已取消");

                } else {//正在处理 更新进度
                    if (mProgressDialog != null)
                        mProgressDialog.setProgress(progress);
                }
            }

            @Override
            public void onError(Throwable t) {
                if (mProgressDialog != null)
                    mProgressDialog.cancel();
                showDialog("出错了 onError：" + t.getMessage());
            }

            @Override
            public void onComplete() {
                if (mProgressDialog != null)
                    mProgressDialog.cancel();
                showDialog("处理成功");
            }
        });
  • FFmpeg 命令执行 (普通方式)
String text = "ffmpeg -y -i /storage/emulated/0/1/input.mp4 -vf boxblur=25:5 -preset superfast /storage/emulated/0/1/result.mp4";

String[] commands = text.split(" ");

RxFFmpegInvoke.getInstance().runCommandAsync(commands, new RxFFmpegInvoke.IFFmpegListener() {
            @Override
            public void onFinish() {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        if (mProgressDialog != null)
                            mProgressDialog.cancel();
                        showDialog("处理成功");
                    }
                });
            }

            @Override
            public void onProgress(final int progress) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        if (mProgressDialog != null)
                            mProgressDialog.setProgress(progress);
                    }
                });
            }

            @Override
            public void onCancel() {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        if (mProgressDialog != null)
                            mProgressDialog.cancel();
                        showDialog("已取消");
                    }
                });
            }

            @Override
            public void onError(final String message) {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        if (mProgressDialog != null)
                            mProgressDialog.cancel();
                        showDialog("出错了 onError：" + message);
                    }
                });
            }
        });
  • 中断 FFmpeg 命令
RxFFmpegInvoke.getInstance().exit();
