[MEncoder-users] mencoder -ovc and 5.1 stream problem

[Troy Perkins]

AH! Thanks Duane!

I experimented with the arrangement of the switches and finally landed one
that works!  One question though:  Is there a way to NOT have to specify the
aid and just copy the 5.1 stream?  I am writing a script to que and run
multiple encodes and having to hunt for the proper aid makes the automation
a little difficult.

mencoder dvd://1 -dvd-device /archives/dvds/OFFICE_SPACE/ -v -oac copy -aid
129 -channels 6 -alang English -ovc xvid -xvidencopts bitrate=2526 pass=1
-o "/dev/null"

I think RC was trying to tell you to include the option, "-aid 129" as 
you specify English , but mencoder is taking the first english audio 
stream (stereo) it finds, which is not the 5.1 stream.
