Because we just removed target by removing AC_CANONICAL_TARGET,
and host is correct anyway.

It wrongly claimed the returned buffer was owned by libtheora, when
 in reality libtheora was creating a temporary buffer and not
 storing the pointer to the returned packet anywhere.
Since there's no encoder parameter passed to this function, it
 doesn't even have a place to store it.
This situation is sub-optimal, but can be solved by migrating to
 the 1.0 API, which does require an encoder instance to encode a
 comment, and thus does not have this problem.

Fixes #726.

This extends the fix from r17276 dealing with the removal of the DC
 skip-prevention flag in r17174.
If we allow SKIPing even when the cost is right near the maximum
 representable SSD, then the cost of other blocks can push it over
 the edge, causing us to randomly skip a block halfway through the
 macroblock.

THEORA_DISABLE_FLOAT C preprocessor symbol.

This originally disabled slow floating point code in the library,
but the critical path code has all been removed. It also used
to disable function of th_granule_time() which returns a double,
but it has not done so since prior to the 1.0 release, and there
have been no complaints.

It might be helpful to restore this option if it eliminated    
the th_granule_time() API entry entirely, so that platforms
without native floating point don't have to link to an emulation
library, but in the absence of a request we prefer shorter code.

The 'debian' subdirectory was removed from the dist target in r10741.

svn path=/trunk/theora/; revision=17914

It's against Debian policy to keep this upstream, so neither we nor our
 packagers have maintained it in quite some time, and its presence simply
 confuses people.

The final argument to TIFFReadRGBAImage is 'stopOnError'. That is,
if it's not true then the function will return success even if
loading the actual image data failed. As such, copying the example
code out of the documentation wasn't really what we wanted.

This is a modified version of png2theora, using libtiff
instead of libpng to read a sequence of tiff image files
and convert them to an Ogg Theora video.

Originally added because the Sintel film project was
giving us tiff frames and waiting for conversion to
png before encoding was tedious. In fact, it nearly
took longer than creating this program.

I've always found two different API links for libtheoradec hard
to find on the main documentation page. This reformats them to
be more obvious, and shifts the emphasis further away from the
legacy api.

I've also added notes about which library to link with to the
API groups in codec.h.

We normally ask doxygen to generate latex source, but don't
actually run it through latex as part of the standard build.
If desired, a 'refman.pdf' can be created manually with
'make -C doc/libtheora/latex'.

Using latex+dvipdf turns out not to work, and pdflatex generally
does a better job anyway.

We try to build the doxygen api documentation if the tool is

This change inserts a new speed level OC_SP_LEVEL_NOSATD (3)
between OC_SP_LEVEL_FAST_ANALYSIS (still 2) and OC_SP_LEVEL_NOMC
(now 4). The new speed level further accelerates analysis by
using the cheaper SAD (sum of absolute differences) metric
for measuring distortion instead of the more expensive SATD
(sum of absolute transformed differences).

The new level is intermediate in both quality and encoding
speed between the adjacent speed levels, allowing smoother
adaptation to realtime encoding contraints. In particular
it's much closer to realtime 720p30 on current Core2 cpus.

The cheaper SAD metric is now also used for the fastest NOMC
speed level. This is a reduction in quality for this speed level
as well, but it also about 10% faster. Since the NOMC mode is
already very poor quality, used as a last resort when performance
is critical, we deemed this a better option than adding a further
NOMC_SATD mode or keeping the old NOMC behaviour.

To suppor...

This is helpful for casual benchmarking and performance comparision.
We use the very portable time.h clock() call and the beginning and
end of the main function and calculate the average rate in millions
of pixels per second and fraction of realtime. Unfortunately clock()
isn't accurate enough to be useful for per-frame statistics.

This was only used when a stream started without a keyframe, and was
 initializing the wrong region of memory.
This was harmless (the region it initialized was still safely
 allocated, it just didn't cover all of the frame we wanted to use
 as a reference frame), but lead to unpredictable results and
 valgrind errors.
