推荐答案

您有两种方法可以做到这一点:

You have two way to do that:

• 将其编码为较低的比特率和/或较低的分辨率.在这里看看:是否可以在Android上压缩视频?.

尝试压缩/压缩它.在这里看看: http://www.jondev.net/articles/Zipping_Files_with_Android_%28Programmatically ％29

Try to zip/compress it. Have a look here: http://www.jondev.net/articles/Zipping_Files_with_Android_%28Programmatically%29

不幸的是，我从未尝试使用140MB的视频来做到这一点.这就是为什么我向您建议第一个库(FFmpeg 4 Android)的原因.

Unfortunately I never tried to do that with a 140MB video. This is why I suggested to you the first library (FFmpeg 4 Android).

顺便尝试增加服务器上的UPLOAD_LIMIT.但这不是问题，即使将其增加到10MB，也仍然必须对其进行压缩.不要尝试将UPLOAD_LIMIT增加到140MB，这肯定会导致HTTP超时.

By the way, try to increase also your UPLOAD_LIMIT on your server. But this is not the problem, even if you increase it to 10MB you still have to compress it. Do not try to increase the UPLOAD_LIMIT to 140MB, it will cause for sure an HTTP timeout.

否则，您需要启用分块上传.

Otherwise you need to enable a chunked upload.
