This is intentional (and a reason why fast usually should not be used),
but a few people sent patches to "fix" this recently so it would be
better to document this.

Not all applications (e.g. MPlayer) set block_align, and
when using a different demuxer it might not even be
easily available.
So fall back to selecting mode based on bit rate as before
if block_align has not useful value.
It can't be worse than failing to decode completely.

Inline functions declared without extern do not provide an external
definition in standard C99. This code only works because most
compilers do not implement the inline semantics correctly. With a
stricter compiler, linking fails with unresolved references to these
functions.
Declaring the functions extern inline works correctly with some
compilers while some others still fail to create external definitions.
For maximum portability, create a static inline version with an
externally visible wrapper for ff_get_mb_score. ff_epzs_motion_search
is so large that no sane compiler inlines it anyway, so there the
inline keyword can simply be dropped with no effect.

Adds a flag context_reinit to MpegEncContext to relieable keep track
of frame parameter changes which require a context reinitialization.
This is required for broken inputs which change the frame size but
error out before the context can be reinitialized.
As a sideeffect this makes the code more robust if a future change leaves
a path where it may be uninitialized otherwise.

This is mainly required for frame parameter changes during frame based
