Encoding to xvid using ffmpeg

[E.J.]

Hi there, i am trying to make a simple frontend to create PSP compliant video files using already existing tools (yes, another one...), is nothing complex, just some programming for the weekend, i want it to have option to choose between .PMP and .MP4 output.

The first part is already done, using mencoder and pmpmuxer, but when looking for a way to make a mp4 playable in the PSP i ended finding out that a custon build of ffmpeg was the best idea.

I would like to use Xvid as video codec, in mencoder the xvid encoding options/parameters are well documented so i didn't have much trouble.

In ffmpeg the encoding options are very similar to mencoder's, but still its not very clear (I think the official doc is a little too simple) about the codec specific options, n-pass modes, resizing algorithms, etc...

Well... the thing is, is there a more explanatory documentation of ffmpeg?, if not, could somebody with a lot of experience with ffmpeg give me some hints about getting the best results?

Thanks in advance.

PD: bad english ;D
