[FFmpeg-soc] Overlaying an animation over a video

[Andy Reece]

I'm trying to get 1 movie to sit over another
I have libavfilter installed but if i run the method described in  
vsrc_movie.c

ffmpeg -i in.avi -s 240x320 -vfilters "[in]setpts=PTS-STARTPTS, 
[T1 
]overlay=16:16[out];movie=3200000:avi:in.avi,scale=180:144,setpts=PTS- 
STARTPTS[T1]" -y out.avi

I get:
no such filter: 'movie'
Error opening filters!

Also I am presuming that this will not allow transparency say in the  
form of a transparent flv
It says that overlay does not really support alpha channels

I can add transparency using imlib2 to attach a png but i need to get  
a 15 frame animation to sit over the top
Can I apply a sequence of pngs to create an animation, ie put 01.png  
at frame 1, 02.png at frame 2 and so forth and loop this?

If there's any documentation that anyone could point me to that'd be  
great
