With weighted P-frame prediction now in x264 and on by default (and
not exposed in ffmpeg), it is impossible to encode Baseline Profile
H.264 with ffmpeg.  This is somewhat of a problem.

Furthermore, the flag for weightb is CODEC_FLAG2_WPRED, which doesn't
contain a "B", and thus doesn't really distinguish between weightp or

Should we change it to CODEC_FLAG2_WPREDB and add CODEC_FLAG2_WPREDP,
renaming the commandline options as well, or what?
