我正在Android中使用FFmpeg创建水印应用程序。 我使用了以下命令
ffmpeg -i /storage/emulated/0/WhatsApp/Media/WhatsApp Video/VID-20150217-WA0002.mp4 -i /storage/emulated/0/mp4parser/img001.png -filter_complex '[0:v][1:v]overlay[out]' -map '[out]' /storage/emulated/0/WhatsApp/Media/WhatsApp Video/trimmed-038-VID-20150217-WA0002.mp4
当我启动应用程序时，我在日志中得到了这一行：
Unrecognized option 'filter_complex'
我在FFmpeg.org网站上看过这个命令，但我不知道为什么它不起作用。以下是日志：

我也尝试过使用过滤器：v。
