发送到服务器之前，Android压缩音频/视频

Question

我想在发送到服务器之前压缩视频/音频文件，因为它需要太多时间上传。我正在使用带有字符串主体的多部分实体将文件上传到服务器上。

我的代码在下面。请给我任何可能的解决方案。该代码正在工作，但需要太多时间。谁能帮助我提高表现？

try {
    if (selectedPath == null || selectedPath == "") {
        getActivity().runOnUiThread(new Runnable() {
               public void run() {
                    Alert_Dialogs.custom_alert_dialog(getActivity(),"Please select Video.");
               }
             });    
    }
    else {
    File file = new File(selectedPath);
    StringBody title = new StringBody(et_title.getText().toString().trim());
    StringBody catId = new StringBody(cat_id);
    StringBody user_data = new StringBody(user_id);
        FileBody filebodyVideo = new FileBody(file);
    CustomMultiPartEntity customMultiPartEntity = new CustomMultiPartEntity(new ProgressListener() {
        @Override
        public void transferred(long num) {
            publishProgress((int) ((num / (float) totalSize) * 100));                               }
    });

    customMultiPartEntity.addPart("title",title );
    customMultiPartEntity.addPart("catId",catId );
    customMultiPartEntity.addPart("user_id",user_data );
    customMultiPartEntity.addPart("qqfile", filebodyVideo);
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(Application.UploadVideosEndpoint());
    //  static_url+"WS/videoUpload?api="+static_api_key
    totalSize = customMultiPartEntity.getContentLength();
    httppost.setEntity(customMultiPartEntity);

    HttpResponse response = httpclient.execute( httppost );
    HttpEntity resEntity = response.getEntity( );

    str_response = EntityUtils.toString(resEntity);

    if (resEntity != null) {
      resEntity.consumeContent( );
    }
    httpclient.getConnectionManager( ).shutdown( );
}

} catch (ClientProtocolException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

您可以将要发送的数据的.zip文件制作。通过制作ZIP数据将被压缩（因此尺寸降低）。

这是有帮助您的代码的工作示例。
