[FFmpeg-soc] expand filter (alternative to pad syntax)

[Ryo Hirafuji]

Hi.
I simplified the source.
"sscanf" works very well, thanks. ^^

I have some questions.

So... you mean that I should post ffmpeg-dev with a patch of libavcodec?

Yes, but "vf_drawbox" also draws images into the memory directly.
(please see "draw_box()")

...Oh,sorry.I think I don't understand the probrem very well.
Which is the probrem, src or dst of memcpy?
