video - 在视频 #2 中重新缩放和重新定位 FFMPEG 中的图像

Question

我正在尝试使用 Mobile-FFMPEG 来实现此结果：

使用以下命令：

电子/命令：

ffmpeg -y -loop 1 -t 10 -i /storage/emulated/0/InvitationTemp/image.png -s 991x903
-loop 1 -i /storage/emulated/0/InvitationTemp/image_0.png 
-loop 1 -i /storage/emulated/0/InvitationTemp/image_1.png 
-loop 1 -i /storage/emulated/0/InvitationTemp/image_2.png 
-loop 1 -i /storage/emulated/0/InvitationTemp/image_3.png 
-loop 1 -i /storage/emulated/0/InvitationTemp/image_4.png 
-filter_complex

但是我收到了这个输出......未能正确地重新调整和重新定位我的 png。
