我在服务器上传之前需要视频大小，并希望调整视频大小以确保它不会达到阈值。
到目前为止，我最终得到了这个命令：
ffmpeg -y -i E:\test3.mp4 -s 640*480 -r 15 -aspect 3:4 -ab 12288 -vcodec mpeg4 -b 2097152 E:\debug_video.mp4
此命令的问题： - 它是否会改变视频的宽高比 - 它工作得太慢（Nexus 5上12秒24mb视频30秒）
到目前为止，第一个问题的最佳解决方案是首先检查视频分辨率，而不是运行ffmpeg。
您是否知道如何在ffmpeg的帮助下将其作为两个单独的命令或单个命令？你知道如何让它更快吗？提前谢谢
UPDATE
控制台输出如下。如果您想获得onProgress回拨
