Option movflags not found.
推荐答案
首先你实际上并没有使用ffmpeg FFmpeg，但是没有 -movflags 选项的fork的旧的和过时的版本。您将需要更新您的ffmpeg：您可以简单地下载ffmpeg的Linux版本（见< a href =https://askubuntu.com/a/270107/59378>详细说明），或者您可以按照一步一步的步骤在Ubuntu上编译ffmpeg的指南。
First of all you're not actually using ffmpeg from FFmpeg, but an old and outdated version from a fork which does not have the -movflags option. You will need to update your ffmpeg: you can simply download a Linux build of ffmpeg (see detailed instructions), or you can follow a step-by-step guide to compile ffmpeg on Ubuntu.
