MJPEG Tools Svn

o Updated the description of "-I" and "-z"
o Added notes to "-F", "-a": 'Taken from input stream header by default.'
o Added a couple of missing .PP's

Reinstate fieldenc-from-input-header patch (updated):

4:2:0 (vertical) chroma subsampling is dependent on interlacing vs.
progressive, and the MPEG decoder decides which to use based on
'progressive-frame' flag, and this flag is set/cleared in the MPEG
stream by 'fieldenc' parameter in the encoder library, so:

o Automagically determine 'fieldenc' (aka "-I n") from the input stream
header's interlacing info (allowing command-line arg to override).

Also:

o Declare "input_interlacing" as 'int', not 'unsigned int'.
o Initialize "input_interlacing" to Y4M_UNKNOWN.
o Promote unknown stream interlacing to 'progressive' for input_interlacing.

Sigh, forgot that lround() is in -lm.

lround() for systems which lack it (old glibc from 2.2.4 era and some of the
BSD variants).

Need to check for lround() - not all systems have it ;(

-Q description was incorrect - the one reference to 0.0 should have been 5.0.

Fixing formatting error (unsplittable line)

Align mplex documentation and command line wrapper w.r.t. to
timing unit suffixes.

Merged nice feature for setting A/V offset in different units
including MPEG clock ticks.

Increase overhead allowance for non-standard Muxing to the same
as standard VCD (2.5%)... makes muxing more stable.
