That should be 1000*8
You may be getting some rounding errors, shell only does integer maths.
You are using the size of the ogg file which includes the ogg container
overhead, on the other hand you are making no allowance for the ogm
You may not need all that bitrate, what does mplayer say the final
file's bitrate is? Does it match the calculation?
