I've noticed that avienc.c is close to useless for use with stdout. It
only checks pb->seekable in a few places, and for example the
ff_end_tag() function uses avio_seek(), but that one is used in several
places where there is no check for a seekable stream.
Anyway, this version adds the AVISF_VIDEO_PALCHANGES flag properly to
the 'strh' chunk, per the Microsoft documentation.

encoded with Microsoft Video 1 (CRAM).
