Video files not enabled (Panda 1.9)

Hi,

I am using the legacy Panda3d 1.9.
I have a video playing in my app and it works fine in ppython main.py mode, but after packing the app to .p3d with packp3d, the video is not showing. I have include “-n avi -n mp4” in my packp3d command… any ideas how to ‘enable videos’?

:movies(error): Support for video files with extension .mp4 was not enabled.

Have you specified -r ffmpeg as dependency?
