Java 在Android上将视频分成若干部分

我正在尝试向android上的asp.net服务器发送视频。但是，由于视频大小约为26 MB，我无法发送视频？有没有一种方法可以将视频分成几个部分，并使用java通过android将其发送到.net服务器

    Intent intent=new Intent();
    intent.setType("video/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);

首先，如果视频在重新组装之前不需要播放，只需在每个片段中发送这么多字节，然后让服务器重新组装即可。其余部分将假定您需要将其划分为多个视频，这些视频可以单独播放

您可能会看到ICS中的视频编辑示例，但这取决于它的实现方式，可能会限制您使用最新的设备

否则：

大多数压缩视频格式可以被认为是绝对信息（关键帧）的重复序列，然后是相对于该基准编码的帧的相对信息。如果您了解了所使用的未指定格式的详细信息，您可能会了解如何在新节以完整关键帧开始的位置，确定您希望剪切的尺寸附近的位置。您可以在那里分割视频，在新部分中创建任何必要的文件头，并调整原始头中的任何长度信息

虽然自己这样做会有教育意义，但也值得寻找现有的解决方案

谢谢你的回答，但是你能给我ICS中视频编辑示例的链接吗？另外，当我尝试开始上传时，我的内存不足。
