[gentoo-amd64] More mencoder fun

[Mark Haney]

Okay, I'm obviously a newbie at video encoding.  I'm trying to encode a
file with xvid with mencoder.  All the HOWTOs on the web indicate I do
it this way (or similar):

-ovc xvid -xvidencopts

with mencoder, however, when I do that I get this:

MEncoder SVN-r24130 (C) 2000-2007 MPlayer Team

-xvidencopts is not an MEncoder option

Is this due to xvid maybe not being compiled into mencoder?  Do I need
to add xvid (or similar) to my make options?  Or is this a deprecated
option?

I can't find this option in the man page, so I'm really confused.  Any help?

You should build with the xvid use flag.  Every use flag that you
would want to encode with really.

Try mencoder -ovc help and see if xvid is available.


Here is a very simple command that uses xvid and lame.

mencoder -ovc xvid -oac mp3lame -xvidencopts bitrate=800 -o test.avi
~/generals_and_majors_drink_from_my_cup.mp4

-xvidencopts expects some xvid configuration options after it.  At a
minimum  you'll need to give it either a bitrate like I've done here
or a fixed_quant=x  (x must be between 1 and 31).


You'd be better off using some of the more advanced xvid options and 2
pass encoding if you want it to look good.  If you really really want
it to look good I'd move right on to x264 and skip xvid, but thats
another matter.

Hope that helps.

Yes that helps a great deal.  How does x264 stack up on file size?  Does
it play 'out of the box' on a windows system?  I've been struggling to
get a decent quality/filesize ratio for a video going on our website.

Perhaps VP6 (Aka flash/shockwave).  It´s not really that bad...for what
it is.  Supposedly it´s implemented in libavcodec (FFmpeg).  I have not
used it, but I suspect better performance with it for what your doing
than xvid.  I assume though, that you´re not literally streaming movies
with HTTP.

Heck no, I'm not streaming any movies, just a 10min presentation that I
wanted to be as small as possible without sacrificing quality.  With
MPEG4 I managed to get it to 23MB (from 70MB originally).
