Well I've found a confusion in the lavc opts in the man documentation.
-----Copy&Paste---
aspect=<x/y> Store movie aspect internally, just like
MPEG files. Much nicer solution than
rescaling, because quality isn't de-
creased. Only MPlayer will play these
files correctly, other players will dis-
play them with wrong aspect. The aspect
parameter can be given as a ratio or a
floating point number.
Example:
aspect=16/9, aspect=1.78
^^^^
---------
This number is a decimal number, and its slightly different that 1,78
in mplayer command line 1,78 is not equal at 1.78 and when doing:
mencoder -v -dvd 1 -ovc lavc -lavcopts vcodec=mpeg4:aspect=2.35:vbitrate=1340:.....
^^^^^
this command line don't works, but:
mencoder -v -dvd 1 -ovc lavc -lavcopts vcodec=mpeg4:aspect=2,35:vbitrate=1340:.....
^^^^^
works fine.
In the DOCS dir in encoding.html there is a final text explaining the :aspect=16.0/9.0 again, and it must be :aspect=16/9 or :aspect=16,0/9,0 for lavc opts internals.
Perhaps is obvious for all, but for a newbie like me, confused a lot when trying to assimilate all contents of the mencoder theory....
Thanks very much for your attention.
