使用FFMPEG4Android图像重叠失败

Question

I am trying to watermark a video using FFMPEG4Android. I am using the app on the android market from here .

The command used is

ffmpeg -i /sdcard/videokit/in.mp4 -i /sdcard/videokit/logos/1.png -i /sdcard/videokit/logos/2.png -i /logos/3.png -filter_complex "[0:v][1:v] overlay=main_w-overlay_w-10:main_h-overlay_h-10:enable='between(t,0,1)' [tmp]; [tmp][2:v] overlay=main_w-overlay_w-10:main_h-overlay_h-10:enable='between(t,2,3)' [tmp2]; [tmp2][3:v] overlay=main_w-overlay_w-10:main_h-overlay_h-10:enable='between(t,4,5)'" /sdcard/videokit/output.mp4

But everytime I run the command the app fails

Opening an output file: overlay=main_w-overlay_w-10:main_h-overlay_h-10:enable='between(t,0,1)'. No such filter: '' Error configuring filters. exit_program: 1

Can I get any help for the same?
