no, Michael and Loren; I added only part of the code

Mencoder refuses to mux to lavf unless you specify :i_certify.... because
it can't guarantee correct PTS when b-frames are present
(because it doesn't parse frames before muxing, unlike muxer_mpeg.c).

Additionally, mplayer demuxes only bytestream H264 ES,whereas mov/mp4
wants NAL (the other) form.
I don't now if lavf's muxer is able to/does convert from bytestream->NAL 
when muxing.
