MJPEG Tools Svn

Add -X option for creating 10bit Quicktime files. With -X '2vuy' becomes 'v210'
and 'v308' becomes 'v410'. Also, use libquicktime's ability to perform the
packing from planar data instead of doing it inline in this utility.

Last required conversion (444P16 -> 444P) is in libquicktime (cvs).

libquicktime (cvs) now has the 422P16 -> 422P conversion.

Need <stdlib.h> for abs():
motionsearch_deint.c:230: warning: implicit declaration of function 'abs'

libquicktime's been fixed (in cvs) so the calls to set_row_span are no longer
needed. Alas, this means using qttoy4m with the current released libquicktime
will generate garbage. But a libquicktime release is fairly close from the
sounds of things.

Suggestion from the libquicktime maintainer. 420P is "JPEG/MPEG-1" siting,
411P can be output IF libquicktime's built with ffmpeg/libavcodec. Can't
use lqt_get_chroma_placement() until a new libquicktime release is made - for
now just put ifdef'd code in place.

libquicktime's in a state of flux. QUICKTIME_YUV444 no longer exists (which is
fine - it was not a correct name to begin with) - use QUICKTIME_V308 instead.
IF this causes problems with programs using libquicktime 0.9.7 or older then
a workaround will be implemented.

Fix the errors (the getopt was a real typo that could crash the program)
y4mhist.c:142: warning: format %i expects type int, but argument 3 has type long int
y4mhist.c:144: warning: format %i expects type int, but argument 3 has type long int
y4mhist.c:146: warning: format %i expects type int, but argument 3 has type long int
y4mhist.c:300: warning: passing argument 2 of getopt makes pointer from integer without a cast

Graphical capability added (by Bernhard Praschinger) to y4mhist. This depends
on SDL_gfx being installed (which currently does not build on OSX) so a
HAVE_SDLgfx check is necessary. THe graphical code is ifdef'd on HAVE_SDLgfx,
if not that is not installed y4mhist behaves as it always has, if SDL_gfx
is present the text mode can be requested with "-t".

Suppress GOP splitting if B structure must be maintained and closed GOPs are required.

Add GOP-wise batching into pass 2 (ready for re-encoding based on GOP complexity for look-ahead / 2-pass encoding).
