[Diego Biurrun]

Two weeks without reaction...

Come on guys, please help me finish the documentation, we are near a
release!


There are a few options that are still not described in the man page.
Please tell me whether I missed any and help me fill in the blanks:

vf decimate

prefer-ipv4/6

ipv4-only-proxy

tsfastparse

dvbin + subopts

sub-demuxer

(no)autoexpand

oldpp

nuvopts

subopts


Thanks

Diego
