推荐答案

您可以在Android项目中使用ffmpeg压缩视频.

You can use ffmpeg in your Android project to compress video.

有很多方法，但是一种常见的方法是在ffmpeg命令行工具周围使用包装器.这使您可以使用mpeg的常规语法，该语法已被很好地证明.

There are a number of approaches but a common approach is to use a wrapper around the ffmpeg command line tool. This allows you use the regular syntax off mpeg which is well documented.

作为示例，此代码使用ffmpeg在Android中压缩mp4文件:

As an example, this code uses ffmpeg to compress an mp4 file in Android:

String argv[] = {"ffmpeg", "-i", videoFileToCompress.getAbsolutePath(), "-strict", "experimental", 
                                                "-acodec", "aac", compressedVideoFile.getAbsolutePath()};

int ffmpegWrapperreturnCode = FfmpegJNIWrapper.call_ffmpegWrapper(this.ctx, argue);

以上内容来自 https://github.com/mickod/ColabAndroidHelper ， ffmpeg包装器.

The above, from https://github.com/mickod/ColabAndroidHelper, uses a custom ffmpeg wrapper.

我认为，现在有许多Android ffmpeg包装器库似乎都得到了很好的支持，并且最好使用，例如-

There are a number of Android ffmpeg wrapper libraries now which seem to be well supported and which would be better to use, I think - one example is:
