http://www.pspvideo9.com can autoconvert all files dropped into a directory to PSP format, and copy them to the PSP.
Underneath the hood it is just using FFMPEG to do the convertion, so it shouldn't be too difficult to reproduce the same behaviour via a plugin. http://www.artfahrt.com/psp.html
Wish I had time to do this, would really like to get my teeth stuck into a MP plugin. Might have to try squeeze it in at some point.
BTW - ipod encoding is very similar
