It would be fairly safe to assume that the lav stuff deal with MJPEG (and DV), 
not MPEG. lavrec, for example, create .avi, .mov and-so-on files containing 
MJPEG video streams, and lavplay plays them.

YUV streams are used as the internal format of mjpegtools; uncompressed, hence 
lossless, and structurally simple and easy to handle.

About the only things that handle MPEG, as far as I know, is mpeg2enc, which 
produces MPEG streams, and mplex, which is able to multiplex them. It's 
entirely possible to let something (mplayer?) play an MPEG stream with y4m as 
output format, and pipe that stream into the stabilizer.
