ffmpeg without dynamic memory allocation

Description of Patch

Why always allocate a whole AVFrame?

Floatingpoint arithmetics failed after ffmpeg_deinterlace (used by sdl),

but a call to "emms" fixed this problem for me.

Installation of Patch

Download the patch file (patch against svn).

patch < ffmpeg_deinterlace.diff

Then re-build Motion and test the patch.

Discussion and Comments

emms is not available on my platform (NSLU2, ARM), and compilation fails there. In addition, it looks like a call to emms is already performed in ffmpeg_deinterlace, when the MMX instructions are available.
