Problem converting MPEG2 to FLV with MEncoder

[mspo]

Hi,

I was trying to follow 45tripp's guide for good quality videos with Youtube, but I'm having a bit of trouble converting any mpg file to flv.

The program I'm using to create the MPEG in the first place is ProShow Gold. I have no avi export option, and the only good quality one available is MPEG 2.
So I've exported the file with that format, and am trying to encode it to FLV with mencoder, using the following command:

mencoder vid.mpg -o test5.flv -sws 9 -of lavf -ovc lavc -lavcopts vcodec=flv:vbitrate=600:trell:v4mv:mv0:mbd=2:cbp:aic:cmp=3:subcmp=3 -oac mp3lame -lameopts abr:br=128:mode=3

I immediately get a popup error saying: "mencoder.exe has encountered a problem and needs to close. We're sorry for the inconvenience."

In case it is of any use, this is how far it gets in the command prompt:

It works fine for avi files, and I was also able to convert a m1v file to FLV, though of course without sound - it just seems to be stuck on the mpg files.

Granted, I could convert the mpg to avi and then to flv, but converting to avi results in an incredible loss of quality.

I'm using the latest version of mencoder.




I tried this on my laptop, which runs Windows Server 2003, and it runs without a glitch, though the FLV files it creates are all fxxked, regardless of the source.





Also, I'm not sure if this is related, but when I try to mux i.e. an avi or m1v file and any sort of audio file, mencoder crashes again. It's definitely the -audiofile switch, because it crashes whenever I insert that command, regardless of the rest of the command.



Anyway if anyone can help, I'd be grateful, as I've just discovered mencoder yesterday and as they say, once you go black you never go back.


Cheers

EDIT



This is what I get when doing step one, part two (ffmpeg):

At that point it crashes just like mencoder.

Well, I've managed to do the continuation of Step 1 from my laptop for god knows what reason, seeing that my desktop is my station with everything installed on it and my laptop has nothing. Ah well, I'm satisfied with that.

nothing wrong with the command.
look to the builds.

Try it with a mencoder build that's compiled for athlon
http://esby.free.fr/CelticDruid/mirror/mplayer/

I've heard of ffmpeg crashing on athlons when trying to encode to mp3...
again try another build, don't use celtic druid's, try this:
