如何使用开始和剪切功能修剪视频在Android中以编程方式结束时间? [英] How to trim the video with start & end time in android programmatically?

问题描述

我想以编程方式在android中根据开始时间和结束时间来修剪本地视频，我尝试在下面附加一些链接，但对我没有用.请让我知道任何可用的库或示例代码来克服这个问题?

3. https://superuser.com/questions/377343/cut-part-from-video-file-from-start-position-to-end-position-with-ffmpeg

提前谢谢！

解决方案

使用FFMPEG库解决您的问题.感谢您的写作心思，使ffmpeg对于Android变得简单1. 实现'com.writingminds:FFmpegAndroid:0.3.2'

2. 初始化ffmpeg

     private void setUpFFmpeg(){ffmpeg = FFmpeg.getInstance(context);尝试 {ffmpeg.loadBinary(new LoadBinaryResponseHandler(){@Override公共无效onStart(){Log.d("Event"，"onStart");}@Override公共无效onFailure(){Log.d("Event"，"onFailure");}@Override公共无效onSuccess(){Log.d("Event"，"onSuccess");}@Override公共无效onFinish(){Log.d("Event"，"onFinish");}});} catch(FFmpegNotSupportedException e){//处理设备不支持FFmpeg的情况}} 

3. 使用 FFMPEG命令，例如上面发布的@Mahesh Keshvala.做得好@Mahesh

4. 然后 execFFmpegBinary(complexCommand); 将像这样

     private void execFFmpegBinary(String []命令){尝试 {ffmpeg.execute(commands，new ExecuteBinaryResponseHandler(){@Override公共无效onStart(){Log.d("Event"，"onStart");}@Overridepublic void onProgress(String message){Log.e("Event"，"onProgress-" +消息);}@Overridepublic void onFailure(String message){Log.e("Event"，"onFailure-" +消息);}@Overridepublic void onSuccess(String message){Log.e("Event"，"onSuccess-" +消息);}@Override公共无效onFinish(){Log.e("Event"，"onFinish");}});} catch(FFmpegCommandAlreadyRunningException e){//处理FFmpeg是否已在运行}} 

尝试剪切视频的命令

  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}；

解决方案

Use FFMPEG library to solve your problem. Thanks for writingminds to make ffmpeg simple for android 1. implementation 'com.writingminds:FFmpegAndroid:0.3.2'

2. initialize 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 command like @Mahesh Keshvala posted above. Good work @Mahesh

4. then execFFmpegBinary(complexCommand); will be like this

   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
    }
   }
   

try command for cut video

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};
