How was this file created? It most likely is non-compliant to the specification (at least the H.263 one).
To play non-conformant files, -lavdopts er=0 can be used.
If this file was created by some official software, it should be reported to FFmpeg, since the same issue happens there when using the -er option.
I am closing this because either this is a broken file or the issue is actually in the FFmpeg decoder (not because the issue itself is not valid).
As a side note, note that rc2 is about 2 years old and not really supported by us any more, bugs are preferably tested against latest SVN first.
Either way, thanks for the report and if you could file a bug against FFmpeg that would be appreciated (for FFmpeg, easiest way to reproduce this is to use "ffplay 1_200907gaoshuzhong.flv -er 2").
