This is driving me crazy, I can't seem to use the movie source in any way at

Trying to overlay one video on another doesn't work either:

"movie=overlay.mp4 [movie]; [in] [movie] overlay=720:480 [out]"

I still get AVERROR -22

Maybe I'm setting up the filterchain wrong, I just followed filtering.c, but
I can get other filters to work, just not when using the movie source
