Discussion and Comments

Wow, I did a very similar thing yesterday, using ffmpeg also. With this patch though, won't timestamps be distorted? Here is what I did, attached as deint-motion-20051215-051001.diff.

There is a memory leak somewhere in my patch. I will hunt it down as soon as possible.

I think I have fixed the memory leak. Performance when using deinterlacing on two cameras at 4 fps each at 640x480 uses about 3-4% cpu on my Athlon XP 2500+.

I just looked at the patch itself.

If Motion is compiled without ffmpeg it seems some #ifdefs are missing in motion.c where the deinterlace function is called.

Yes, you are right Kenneth. Here is a new patch.

I have integrated the patch. It will be available in 3.2.5_snap1. Thank you both for the patch.
