没有这样的过滤器：ffmpeg 中的“ ”

Question

我正在尝试将一系列图像和视频与音频叠加拼接在一起。这以前有效，但是在我添加了更多曲目并增加了语音曲目的音量后，ffmpeg 突然出现了错误No such filter: ' '。我不知道为什么会这样，出于某种原因，似乎唯一可以修复它的方法是完全删除所有过滤器和映射。我正在使用的命令：

编辑：我在过滤器的末尾添加了一个分号以尝试修复它。然而，当我回溯到我的工作命令时，这实际上只是打破了它（此处显示的工作版本没有额外的分号）：

顺便说一下，Volume=volume 是我原来的方法，也没有奏效。

Answer 1

去掉中的分号[outa];。filter_complex 中的最后一个过滤器应该没有分号。
