引入本项目使您的项目尽可能的小，功能尽可能的完善，已使用本项目上线的项目有 [影音坊](http://server.m.pp.cn/download/apk?appId=8061477&custom=0&ch_src=pp_dev&ch=default)。 11 | 12 | 项目支持 androidx 或者 support 13 | 14 | 本项目没有引入任何第三方库，不会对您的项目有任何的代码侵入,可兼容最低api版本为15 15 | 16 | # 项目截图 17 | 18 | 图-1：ffmpeg_version 19 | 图-2：cmd 20 | 图-3：cmd 21 | 图-3：cmd 22 | 23 | ### 体系结构 24 | FFmpeg-Android运行在以下架构上: 25 | - armeabi 26 | - armeabi-v7a 27 | - armv7-neon 28 | - arm64-v8a 29 | 30 | ### 特性 31 | 32 | - 使用最新的 git-2020-01-25-fd11dd500 Copyright (c) 2000-2020 the FFmpeg developers 33 | - 多线程 34 | 35 | ## 使用 36 | 37 | 在项目的 build.gradle 中添加 38 | 39 | 40 | ``` 41 | allprojects{ 42 | 43 | repositories { 44 | ... 45 | maven { url 'https://jitpack.io' } 46 | } 47 | 48 | } 49 | 50 | ``` 51 | 52 | #### 53 | 54 | 1.重新编译了ffmpeg 55 | 56 | 2.支持更多的命令，执行速度更快 57 | 58 | 3.支持在安卓10（aip29）上使用 59 | 60 | 4.支持进度回调，进度为执行文件的进度，如果想计算进度，拿（当前返回进度）除以（文件进度） 61 | 62 | app 的 build.gradle 下添加 63 | 64 | ``` 65 | dependencies { 66 | implementation 'com.github.yangfeng1994:FFmpeg-Android:v2.0.1' 67 | } 68 | ``` 69 | 70 | 71 | 设置支持的so库版本 72 | 73 | ``` 74 | android{ 75 | defaultConfig{ 76 | ndk { 77 | abiFilters 'armeabi-v7a', 'arm64-v8a' //过滤的so库版本 78 | } 79 | } 80 | } 81 | ``` 82 | 83 | #### 友情提示 84 | 85 | - 申请权限（对本地文件处理时，建议您务必申请权限，不然无法对音视频进行操作） 86 | 87 | - 对输入的文件是否存在，进行判断（如您想要输出的文件 已经在手机中存在，将无法对输出文件） 88 | 89 | ### 运行 FFmpeg 90 | 91 | 92 | ##### java 93 | 94 | ``` 95 | // 要执行“ffmpeg -version”命令 96 | 97 | String[] cmd = new String[]{"-version"}; 98 | 99 | FFmpegAsyncUtils asyncTask =new FFmpegAsyncUtils() 100 | 101 | asyncTask.setCallback(new FFmpegExecuteCallback() { 102 | 103 | @Override 104 | public void onFFmpegStart() {} 105 | 106 | @Override 107 | public void onFFmpegSucceed(@Nullable String executeOutput) { 108 | 109 | } 110 | 111 | @Override 112 | public void onFFmpegFailed(@Nullable String executeOutput) { 113 | 114 | } 115 | 116 | @Override 117 | public void onFFmpegProgress(@Nullable Integer progress) { 118 | fload mprogress = progress/执行视频文件或语音文件时长 119 | } 120 | 121 | @Override 122 | public void onFFmpegCancel() { 123 | 124 | } 125 | }) 126 | 127 | asyncTask.execute(cmd); 128 | 129 | 注意，传入的参数是一个lsit 130 | 131 | 如果想要传入string，命令行拼接的时候，需要用空格隔开 使用FFmpegAsyncUtils2就行 132 | 133 | ``` 134 | 135 | ##### kotlin 136 | 137 | 138 | ``` 139 | // 要执行“ffmpeg -version”命令，只需传递“ arrayOf(-version) ”即可 140 | 141 | val asyncTask = FFmpegAsyncUtils() 142 | 143 | asyncTask.setCallback(object :FFmpegExecuteCallback{ 144 | 145 | override fun onFFmpegStart() { 146 | 147 | } 148 | 149 | override fun onFFmpegProgress(progress: Int?) { 150 | 151 | //注意kotlin的除法，建议转为float后，再进行除以 152 | 153 | val mprogress = progress?.div(执行视频文件或语音文件时长) 154 | 155 | } 156 | 157 | override fun onFFmpegCancel() { 158 | 159 | } 160 | 161 | override fun onFFmpegSucceed(executeOutput: String?) { 162 | 163 | } 164 | 165 | override fun onFFmpegFailed(executeOutput: String?) { 166 | 167 | } 168 | 169 | }) 170 | 171 | asyncTask.execute(cmd) 172 | 173 | 注意，传入的参数是一个lsit 174 | 175 | 如果想要传入string，命令行拼接的时候，需要用空格隔开 使用FFmpegAsyncUtils2就行 176 | ``` 177 | 178 | 179 | #### 注意： 180 | 181 | - 所有命令行都不需要以 "ffmpeg"开头，直接命令行就行。 182 | 183 | - 本项目使用的是AsyncTask，需要注意，每个子线程AsyncTask只能执行一次命令，取消后 184 | 应重新new 一个AsyncTask 对象。 185 | 186 | - 混淆在model里面已经添加，无需再次添加 187 | 188 | ### 停止(或退出)FFmpeg进程 189 | 190 | - 如果你想停止运行中的ffmpeg, 只需在调用' asyncTask.onCancel() ' 191 | 192 | #### FFmpegExecuteCallback 接口中方法的介绍 193 | 194 | - onFFmpegStart() 开始执行 195 | 196 | - onFFmpegProgress(progress: Int?) 进度 参数为执行音视频文件的所在的毫秒值 197 | 198 | - onFFmpegCancel() 取消执行 199 | 200 | - onFFmpegSucceed(executeOutput: String?) 执行成功 参数为ffmpeg的执行结果信息 201 | 202 | - onFFmpegFailed(executeOutput: String?) 执行失败 参数为返回为失败原因 203 | 204 | #### 历史版本 205 | 206 | - v1.1.1 优化了代码的逻辑，兼容了低版本的手机，使项目同时兼容androidx与support 207 | 208 | ``` 209 | implementation 'com.github.yangfeng1994:FFmpeg-Android:v1.1.1' 210 | 211 | ``` 212 | 213 | - v1.0.1 移除x86 so包，优化项目大小 214 | 215
