RxFFmpeg

RxFFmpeg is a fast processing framework for audio and video editing and video editing based on (FFmpeg 4.0 + X264 + mp3lame + fdk-aac) compiled for Android platform. It includes the following functions (video stitching, transcoding, compression, clipping, film head and tail, separation of audio and video, speed change, adding static stickers and GIF dynamic stickers, adding subtitles, adding filters, adding background music, adding Speed deceleration video, rewind audio video, audio clipping, voice change, mixing, picture synthesis video, video decoding pictures and other mainstream features...

Compile

Compiling Environment

• win10 + ubuntu 16.04 + gcc + make

Compiling mainly depends on the following Libraries

Library	Version	Download
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

Features

• Supporting any FFmpeg command execution

• Support FFmpeg command execution schedule callback

• Supporting interruption of FFmpeg commands

• Supporting synchronous/asynchronous execution

• Support debug mode on/off

• Supports hardware acceleration to make codec processing faster (MediaCodec is turned on)

• Code encapsulation into SDK, easy to rely on

• Support sub-modules of FFmpeg libavutil libavcodec libavformat libavdevice libavfilter libswscale libswresample libpostproc Ultimately packaged into a libffmpeg-core.so core library for easy dependency use

• Supporting libx264 encoding library, can make the compressed video volume become very small, the clarity remains very high, simple compression commands: ffmpeg -y -i /storage/emulated/0/1/input.mp4 -b 2097k -r 30 -vcodec libx264 -preset superfast /storage/emulated/0/1/result.mp4

• Background music that supports the addition of mp3, aac, wav and other mainstream formats

• Support mainstream video format conversion, such as: avi > mp4 > avi

• Intercept a graph every second: ffmpeg -y -i /storage/emulated/0/1/input.mp4 -f image2 -r 1 -q:v 10 -preset superfast /storage/emulated/0/1/%3d.jpg

Usage Mode

Gradle

Add the Maven repository to build. gradle under the root directory

allprojects {
		repositories {
			...
			maven { url 'https://www.jitpack.io' }
		}
	}

Adding dependencies, latest version

dependencies {
    implementation 'com.github.microshow:RxFFmpeg:4.9.0'
}

Be careful：If your project has so libraries on other platforms, such as arm64-v8a, add the following configuration to build. gradle to keep usage intact

defaultConfig {
    .
    .
    .
    ndk {
        abiFilters "armeabi-v7a"
    }
}

Start

• Open/close debug mode. It is recommended to initialize the call in Application

RxFFmpegInvoke.getInstance().setDebug(true);

• FFmpeg command execution (RxJava2 elegant call)

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 RxFFmpegSubscriber() {
            @Override
            public void onFinish() {
                if (mProgressDialog != null)
                    mProgressDialog.cancel();
                showDialog("Successful");
            }

            @Override
            public void onProgress(int progress) {
                if (mProgressDialog != null)
                    mProgressDialog.setProgress(progress);
            }

            @Override
            public void onCancel() {
                if (mProgressDialog != null)
                    mProgressDialog.cancel();
                showDialog("Cancelled");
            }

            @Override
            public void onError(String message) {
                if (mProgressDialog != null)
                    mProgressDialog.cancel();
                showDialog("onError：" + message);
            }
        });

• FFmpeg command execution (synchronization)

RxFFmpegInvoke.getInstance().runCommand(command, null);

• Interrupt FFmpeg command

RxFFmpegInvoke.getInstance().exit();

Code Confusion

-dontwarn io.microshow.rxffmpeg.**
-keep class io.microshow.rxffmpeg.**{*;}
