问题描述

只是想知道ffplay中使用的过滤器是否真的很重要，或者我只能禁用CONFIG_AV_FILTER并使用它？

Just wanted to know whether the filters used in ffplay are really important or can I just disable the CONFIG_AV_FILTER and use it?

还想知道CONFIG_AV_FILTER。

推荐答案

如果您计划使用过滤器，重要的是过滤器。看看过滤器做什么，然后自己决定。

Filters are only significant if you plan on using them. Have a look at what the filters do and then decide for yourself.

如果你所做的只是用 ffplay 观看视频，那么很可能你不需要它们。如果您使用 ffmpeg ，例如模拟转换为数字转换，则视频的重新编码可能需要它们。

If all you do is just watch videos with ffplay then it's likely you won't need them. If you use ffmpeg for things like analog to digital conversion, re-encoding of videos then it's likely you will need them.
