[Libav-user] mpegencoder (h263) denoise possibilities

I wonder if there is any possibility how to reduce noise of encoded
video in ffmpeg. I'm using h263 encoder in libavcodec compiled for
arm9 to store a stream from camera in my application. For example in a
dark, the images are very noisy and it leads to undesirable video
size. Of course I can write some denoising averaging filter, but maybe
there is some similar feature directly in libav* project. Simply I can
imagine some threshold for decision if a macroblock differs from the
previous (moved) one.
