如何以编程方式在android中修剪视频的开始和结束时间？

我想根据 android 中的开始和结束时间以编程方式修剪本地视频，我尝试了下面附加的一些链接，但对我来说没有用。请让我知道任何工作库或示例代码来克服这个问题？

提前致谢！

使用 FFMPEG 库来解决您的问题。感谢您的 writeminds 使 ffmpeg 在 Android 上变得简单 1.implementation 'com.writingminds:FFmpegAndroid:0.3.2'

2. 初始化 ffmpeg

   private void setUpFFmpeg() {
   ffmpeg = FFmpeg.getInstance(context);
   
   
   try {
       ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
   
           @Override
           public void onStart() {
               Log.d("Event ", "onStart");
           }
   
           @Override
           public void onFailure() {
               Log.d("Event ", "onFailure");
           }
   
           @Override
           public void onSuccess() {
               Log.d("Event ", "onSuccess");
           }
   
           @Override
           public void onFinish() {
               Log.d("Event ", "onFinish");
   
           }
       });
   } catch (FFmpegNotSupportedException e) {
       // Handle if FFmpeg is not supported by device
   }
   }
   

3. use FFMPEG命令 https://stackoverflow.com/a/50501220/9558451就像上面发布的@Mahesh Keshvala 一样。干得好@Mahesh

4. then execFFmpegBinary(complexCommand);会是这样

   private void execFFmpegBinary(String[] command){
         try {
   
       ffmpeg.execute(commands, new ExecuteBinaryResponseHandler() {
   
           @Override
           public void onStart() {
               Log.d("Event ", "onStart");
           }
   
           @Override
           public void onProgress(String message) {
               Log.e("Event ", "onProgress - " + message);
   
           }
   
           @Override
           public void onFailure(String message) {
               Log.e("Event ", "onFailure - " + message);
   
           }
   
           @Override
           public void onSuccess(String message) {
               Log.e("Event ", "onSuccess - " + message);
   
           }
   
           @Override
           public void onFinish() {
               Log.e("Event ", "onFinish");
   
           }
       });
   } catch (FFmpegCommandAlreadyRunningException e) {
       // Handle if FFmpeg is already running
    }
   }
   

尝试剪切视频命令

String[] complexCommand = {"-ss", "" + startMs / 1000, "-y", "-i", inputFileAbsolutePath, "-t", "" + (endMs - startMs) / 1000, "-s", "320x240", "-r", "15", "-vcodec", "mpeg4", "-b:v", "2097152", "-b:a", "48000", "-ac", "2", "-ar", "22050", outputFileAbsolutePath};
