[theora] "max_analyze_duration reached" means what?

[J.B. Nicholson-Owens]

I am trying to encode the Sintel documentary AVI from DVD #3 using 
ffmpeg2theora 0.27 (which is the latest released version).

You can download this AVI file from

http://www.archive.org/download/Sintel/Sintel_Documentary_by_Ali_Boubred.avi

I'm doing this encode on Fedora 13 GNU/Linux on a 64-bit AMD processor.

The program encodes the video but I get something that looks like a 
warning and I don't know what it means:

--------------------------------------------------------------
$ ffmpeg2theora --videoquality 10 --audioquality 10 --optimize --output 
~/out.ogv Sintel_Documentary_by_Ali_Boubred.avi
[avi @ 0x10ff720]max_analyze_duration reached

What does "max_analyze_duration reached" mean?

Thanks.
