As @RomanMinkin mentioned, you can also consider Casbin (https://github.com/casbin/casbin). It is the most starred authorization library in Golang. There are several differences between Casbin and OPA.

Feature	Casbin	OPA
Library or service?	Library/Service	Library/Service
How to write policy?	Two parts: model and policy. Model is general authorization logic. Policy is concrete policy rule.	A single part: Rego
RBAC hierarchy	Casbin supports role hierarchy (a role can have a sub-role)	Role hierarchies can be encoded in data. Also with the new `graph.reachable()` built-in function queries over those hierarchies are much more feasible now.
RBAC separation of duties	Not supported	Supported: two roles cannot be assigned together

	ffmpeg功能极其强大，堪比图像处理的ImageMagik。下面是一些常用的命令，记下备用。
	1：得到视频信息
	ffmpeg -i input.xxx
	2: 将图像序列转换为视频
	ffmpeg -f image2 -i prefix%d.jpg output.xxx
	3:将视频转换为图像序列
	ffmpeg -i input.xxx -r FPS -qscale 1 -vsync 0 $prefix%d.jpg
	其中FPS为每秒抽多少帧
	4:将视频转换为yuv格式
	ffmpeg -i input.avi ouput.yuv
