[MEncoder-users] "Internal buffer inconsistency." Problem

[Sebastian Melchior]

Hi Everyone!

when trying to convert a MOV file to flv we rarely get an "Internal Buffer 
Inconsistency" Error and mencoder crashes. We tried to recompile lame with -O0 
as it was suggest in some other post on the list, but this did not really help. 
(Seems to have only been a Problem with an old lame version).

mencoder has been comipled with a gcc 4.1.2.

I hope someone can give me a hint how to fix this Problem :)

Here is the output of mencoder:
