I am quite strongly opposed to adding basic (i.e. crap) versions of
anything, more so when a perfectly good external library exists and
is supported.  If a basic version exists, users will fail to enable
the proper support, and they'll get bad encoding results, ultimately
tarnishing the reputation of FFmpeg.  Furthermore, a trivial H.264,
if such a thing exists, will not exercise much of the decoder.

I know you wrote a very basic H.264 encoder.  Don't take this personally.
