MJPEG Tools Svn

Another update submitted by Nicolas Boos

Since we use a define, actually include the header that defines it

Updated with patch from Nicolas Boos

applied fix from Bug tracker:
[ 1041159 ] mplex -O: typo in mplex/main.cpp

-O is never satisfied with time offset units when none
given (according to man page, must default to ms.)

"mjpegtools-1.6.2/mplex/main.cpp" line 582 of 621: if(
e ) should obviously be if (*e).

Further speedup of the non-MMX/SSE SAD functions - shortcut the computation if
the current block has become worse than previously seen blocks.

Use inline abs() in the uv_noaccel case (saves an intermediate variable and
calculation).

Add -X to allow bypassing the SIMD (SSE/MMX) routines.
Rewrite the SAD (Luma only) routines to use pointer arithmetic and the
(builtin) abs() function. This speeds up processing almost 25% on a 1GHz G4/PPC

char -> int, seems some systems use unsigned char as the default

Typo and phrasing fixes.

Cleanup and use mjpeg_error instead of printf to stdout. Actually the callback
mechanism could be simply be inlined in lavrec_msg/lavplay_msg since the 'info'
pointer isn't passed thru to the callback routine.
