Re: Changing the framerate after the fact...

Hello,

according to chapter 6.2 of http://www.theora.org/doc/Theora.pdf you 
want to change the framerate nominator (FRN, unsigned integer, 32bit) 
and denominator (FRD, unsigned integer, 32bit) of the identification header.

Have a look at figure 6.2 to see what bytes to modify.
