BUG: warning, clipping 1 dct coefficients to -127..127

When generating msmpeg4 movies with motion the ffmpeg code produces this

[msmpeg4v2 @ 0xb44350]warning, clipping 1 dct coefficients to -127..127
[msmpeg4v2 @ 0xb44350]warning, clipping 1 dct coefficients to -127..127
[msmpeg4v2 @ 0xb44350]warning, clipping 1 dct coefficients to -127..127
[msmpeg4v2 @ 0xb44350]warning, clipping 1 dct coefficients to -127..127

What it is it complains about?

And can we either fix it or suppress those errors?

Test case

It seems like it have to be daylight when you test this to get the error. I rarely see it when I code at night.

Environment

Motion version: 3.2.2_snapX
ffmpeg version: 0.lvn.0.15.20050427.4
Shared libraries: curl, xmlrpc, ffmpeg, mysql, postgresql
Server OS: FC4

Follow up

I tried to install ffmpeg CVS from 13 Aug 2005 and I no longer see the problem. But I have to try again tomorrow at daylight. I think the issue was in ffmpeg and is resolved in the ffmpeg CVS. So nothing to do for Motion

I was wrong. The problem is back with the daylight.

Fix record

It must have been a bug in ffmpeg because the problem is no longer there with new ffmpeg versions.

I am also seeing this, in daylight [just seen it now, not yet tested in darkness] with ffmpeg snapshot 20060306-certified-with-motion-3.2.5. I am using motion 3.2.6 with this. Hardware: NSLU2 with Openslug 3.1.
