Previously the duration was sometimes wrong, this addition
limits the value and improves which frames are choosen when
reducing the frame rate

This is a bit ugly as it attempts to keep most of the computation
in integers before the double based fps code. The use of integers
is to reduce the chances of rounding differences between platforms

Previously the timestamp was rounded to the encoder timebase
before being converted back to double precision which could cause loss
of precision

This fixes sending chunked packets (packets larger than the output
chunk size, which often can be e.g. 4096 bytes) with a timestamp delta
(or absolute timstamp, if it's a timestamp step backwards, or the
first packet of the stream) larger than 0xffffffff.

The RTMP spec explicitly says (in section 5.3.1.3.) that packets of
type 3 (continuation packets) should include this field, if the
previous non-continuation packet had it included.

The receiving code handles these packets correctly.
