It makes more sense to print the timebase exactly as it is set. Also,
this avoids a divide by zero when av_dump_format() is called on a format
context before writing the header.

With optimzations disabled compilers have trouble doing dead code
elimination on 'if (foo && 0)' expressions, while 'if (0 && foo)'

checked prior to calling it because no consistency check is done
there.

The language and the program that consumes the language are not the same.

By default they are set to -1.

It is not used outside of the file.

eatqi uses more than just the shared mpegvideo bits.

Instead, store them in the context and compute on each parameter change.

We do not allow the frame parameters to change during encoding, so there
is no need to do this for each frame.
