Help with mencoder configuration profile?

[gambrjl]

I'm trying to set up a profile for encoding video for my creative zen. There's a scale limitation of 320x240. I've created a config file but it's erroring out saying no audio encoder selected but I have the oac flag set.

I apologize if this a repeat. I've found the gentoo wiki mencoder tutorial and trying to learn by the manpage

here's my config file


[zen]
profile-desc="MPEG4/MP3 encoding"
ovc=lavc=1
oac=lavc=1
lavcopts=vcodec=mpeg4:acodec=mp3:abitrate=128
vf=scale=320:240


I don't know what the =1 means on the end of the oac and ovc option I'm copying that from this gentoo tutorial (http://gentoo-wiki.com/HOWTO_Mencoder_Introduction_Guide#Profiles)

Thanks

BTW.. if anyone knows a tutorial that explains the mencoder configuration flags in laymans terms I'd appreciate it

I don't think lavc has an mp3 encoder. You'll need to use Lame for MP3 encoding, as the Gentoo tutorial shows.

It just means that those encoders are to be enabled. You can also use "yes" instead of 1.

See chapters 13 and 14 in the MPlayer/MEncoder HTML documentation: http://www.mplayerhq.hu/DOCS/HTML/en/

Personally, I'd just write shell scripts instead of configuration profiles for MEncoder, but use what you think is best for you.

Thanks nm, appreciate it. I'm not real adept at shell scripting but I'll look into it. I could probably write a python script to do the same thing.

I got the audio settings from the mencoder audio settings in k9copy.. lol

The lame encoding is erroring out, i haven't figure out what is wrong there yet

Thanks nm, appreciate it. I'm not real adept at shell scripting but I'll look into it. I could probably write a python script to do the same thing.
To do the same thing with a simple Bash script, write this to a file (encode.sh) and mark it executable (chmod a+x encode.sh): #!/bin/bash
mencoder -ovc lavc -oac mp3lame -lavcopts vcodec=mpeg4:vqscale=3 -vf scale=320:240 "$@"

Usage examples:
$ ./encode.sh inputfile -o output.avi
$ ./encode.sh -vf crop=704:568,scale=640:-2 -noskip inputfile -o output.avi

(as the second example shows, you can override some parameters specified in the shell script later on the command line)

Multipass encoding is much easier to handle with a script than with MEncoder profiles.

What error do you get? Maybe MEncoder wasn't built with libmp3lame support? It probably needs to be enabled with a USE flag in Gentoo.

I'm at work now but I'll get the exact error tonight. I read somewhere a couple days ago about "--enable-libmp3lame" or something like that in a config file but haven't found it again.

I'm using ubuntu. I just found the gentoo wiki in a google search for mencoder help

And I haven't done any 2 pass encoding yet.. still working on 1

Thanks for the help
