[wmv2 @ 0xb42400] warning, clipping 1 dct coefficients -255..255

i'm modifying code in c api interacts between ffmpeg , and as3 air application encode video after creating something.

wmv working okay before i've set things i'm getting peculiar warning coming c library doesn't create sense , googles not providing many answers.

i wondering if out there knew warning about? when file comes me it's totally empty 0 frames. must have changed i'm comparing file few days ago 1 looking may have caused no longer work. wondering if had improve ideas blindly looking through old , new code.

this particular warning comes ffmpeg core code. warning had perform adjustment on bits of video stream in order decode it. might help understand wmv2 algorithm (being decoded, per error message) reverse engineered binary code , reimplemented in ffmpeg, why things slip through cracks.
