视频压缩

视频压缩用FFmpeg实在是太慢了，26mb的视频要30秒。后来采用了这个方案，需要15秒左右：https://github.com/Tourenathan-G5organisation/SiliCompressor

视频拍摄完成后，开启一个service服务去压缩，压缩任务用list装载，是串行的，一个任务结束后继续下一个任务。

Intent intent = new Intent(this, DownloadService.class);
intent.putExtra(DownloadService.OUTPUT, target);
intent.putExtra(DownloadService.DIR, dir);
intent.putExtra(DownloadService.INPUT, inputDir);
intent.putExtra(DownloadService.HUAN_HAO, zuhuanhao); intent.setAction(DownloadService.ACTION_DOWNLOAD);
startService(intent);
