A few weeks ago I had a problem with some eval code and it was pointed
out that i need to escape the ','.
So here is a small patch that needs passing on to the devel guys to have
a look at.
All this does is to ignore the fixed tokens when inside parenthesis, so
this works now
-filter_complex '[0:v] scale=160:90 [out], [v:0][out]
overlay=x=mod(10,2):y=20'
patch is here
