I accidentally broke it in r18218.

svn path=/trunk/theora/; revision=18794

Patch by Ron Lee.

svn path=/trunk/theora/; revision=18761

Newer versions of png.h don't include it for us.
This is only needed when compiling with OC_DUMP_IMAGES (i.e., for
 debugging).

There was never any reason for these to not be const, and it
 shouldn't break backwards API or ABI compatibility.

svn path=/trunk/theora/; revision=18348

This was broken when the dequant_tables indexing changed in commit
 r16102, but it only affected post-processing quality, so we never
 noticed.
With gcc 4.8.0, this can now trigger a segfault during decoder
 initialization.

Save activity from first pass. Gives a small SSIM improvement (e.g. 0.04dB for 360p elephants dream at 750kbit/s)

Thanks to Holden for the report.

ref_frame_data was being allocated with the aligned allocator, but
 freed with the normal _ogg_free() function on failure, which
 doesn't work.
This would only cause a problem if there was just enough memory to
 satisfy the reference frame allocation (just over 4.5 or 9 bytes
 per pixel) but not enough for the fragment buffer offets (1/16 or
 1/8th byte per pixel).

This allows it to be used from dump_video without having to disable
 striped decoding there.

Thanks to darkstarbyte for pointing out the typo.

svn path=/trunk/theora/; revision=18195

1) Allow specification of the section alignment and make the
    default alignment 4 bytes (like the RVCT manual says it should
    be).
   This ensures that linking our ARM asm into a Thumb executable
    won't get the section placed on a 2-byte boundary.
2) Add a linker hint to indicate we don't need an executable stack.
   Otherwise it assumes we do.
3) Stop building and linking to an (empty) armopts object file.
   This is needed to make 2) work, since we include this file, so
    we can't add the linker hint at the end of it, and linking in
    just one object without that hint makes the whole library ask
    for an executable stack.

This is a more proper attribution for r17993.

svn path=/trunk/theora/; revision=18008

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.

Fixes #1804.

svn path=/trunk/theora/; revision=17989

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.

Make a note that passing 0 for the bitrate may not be guaranteed to
 return an error in future versions.

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 reference in the complete frame decode section was pointing to
 the procedure for decoding a single MV, rather than the following
 one for decoding all the MVs for a frame.

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.

svn path=/trunk/theora/; revision=17856

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.
