android - 初始化复杂过滤器时出错 问题是什么？

Question

我确实在 ffmpeg 命令下执行了视频反转：

   ffmpeg-y-i/storage/emulated/0/Editor/VideoTrim/VideoTrim_134850.mp4-filter_complex[0:v]reverse[v];[0:a]areverse[a]-map[v]-map[a],[0:v]reverse[v];[0:a]areverse[a]-map[v]-map[a]-presetsuperfast/storage/emulated/0/Editor/VideoEdit/1613031543160.mp4


AVLOG: [AVFilterGraph @ 0x7e1f17efe0] Unable to parse graph description substring: "-map[v]-map[a],[0:v]reverse[v];[0:a]areverse[a]-map[v]-map[a]"
AVLOG: Error initializing complex filters.
AVLOG: Invalid argument
