-------------------------------------------------------------------------------- 1 | # FFmpegLibrary 2 | 我们在实际开发过程中有时候会遇到这样的问题，有一个视频我们要拿到它的缩略图或者第几秒时间的画面。 3 | Android系统为我们提供了一个视频处理的类MediaMetadataRetriever，但是这个类一次只能获取一张图片， 4 | 不能批量获取，使用循环太麻烦，而且对于分辨率大的视频时间太长。那么视频处理肯定要用到FFmpeg，使用FFmpeg命令行 5 | 是非常方便的一种方式，对于一般的操作，视频的裁剪、压缩、转码等一条命令搞定。但是命令行在手机上进行某些操作的时候 6 | 效率实在不怎么高，获取分辨率为1920*1080视频的一帧图形花费的时间为0.5秒左右，好处是可以批量获取，但是数量到了几十 7 | 甚至上百的时候，就太漫长了。那么又想快又想批量处理的话就要用NDK直接用c语言对视频解码，找到图像帧转换成jpg保存到本地。 8 | 9 | 10 | 该工程是一个library，有两种使用方式。 11 | 1.直接下载下来，以module方式依赖在自己的项目中。 12 | 2.gradle方式依赖。 13 | 在项目根目录的gradle文件中添加 14 | allprojects { 15 | repositories { 16 | ... 17 | maven { url 'https://jitpack.io' } 18 | } 19 | } 20 | 21 | 再在app的gradle文件中添加依赖 22 | compile 'com.github.kui92:FFmpegLibrary:3.2' 23 | 24 | 25 | 26 | 具体用法：在类FfmpegTool中有两个native方法 27 | //执行FFmpeg命令 28 | public static native int cmdRun(String[] cmd); 29 | 30 | 使用方式： 31 | String cmd="FFmpeg命令"; 32 | 33 | String regulation="[ \\t]+"; 34 | 35 | 36 | final String[] split = cmd.split(regulation); 37 | 38 | 39 | final int result=FfmpegTool.cmdRun(split); 40 | 41 | 42 | 43 | 44 | //将视频解码，每一秒保存为一个jpg图片（因为关键帧的问题，在寻找时间时有时候可能有一两秒左右的偏差） 45 | //srcPath 视频地址 savePath 图片的保存路径 startTime 开始时间 count 要保存图片的数量一秒一幅 46 | public static native int decodToImage(String srcPath,String savePath,int startTime,int count); 47 | 48 | 这两个方法都是阻塞的方法 49 | 50 | 51 | 52 | 53 | 不想自己拼写命令的话还有几个封装方法，内部对命令进行了拼接，外部只需传递参数即可： 54 | 55 | /** 56 | * 视频裁剪 57 | * @param view 58 | */ 59 | public void

}.start(); 133 | } 134 | 135 | 136 | 137 | 138 | 139 | 3.0版本新添加了一个带jni回调的图片解码方法decodToImageWithCall，该方法与decodToImage方法功能完全一样，不过该方法有过程监听，每完成一次图片 140 | 的解码与保存会回调一次decodToImageCall方法（也是一个FfmpegTool类的一个public方法，供jni调用回传参数），并传回新保存图片的地址与当前是图片下标。使用方法： 141 | 142 | FfmpegTool ffmpegTool=FfmpegTool.getInstance(MainActivity.this); 143 | ffmpegTool.setImageDecodeing(new FfmpegTool.ImageDecodeing() { 144 | @Override 145 | public void sucessOne(String path, int i) { 146 | Log.i("decodToImageCall","path:"+path+"___index:"+i); 147 | } 148 | }); 149 | 150 | public void click4(View view){ 151 | new Thread(){ 152 | @Override 153 | public void run() { 154 | String path= Environment.getExternalStorageDirectory().getPath()+ File.separator+"test"+File.separator; 155 | String video=path+"c.mp4"; 156 | ffmpegTool.decodToImageWithCall(video.replaceAll(File.separator,"/") 157 |
