* idct8x8: Fix undefined negative shiftsKaterina Barone-Adesi2016-03-05
| | | | | | | | | | | The original code left-shifts negative values, which is undefined in the C99 specification (the one used during normal Libav compilation). This change multiplies by (1 << shift), which is functionally equivalent, but has defined behavior. With this change, fate-idct8x8 compiled with --fsanitize=undefined works. Bug-Id: 686
* idctdsp: Add global function pointers for {add|put}_pixels_clamped functionsDiego Biurrun2014-09-02
| | | | | | These function pointers already existed in the ARM code. Adding them globally allows calls to the function pointers to access arch-optimized versions of the functions transparently.
* dsputil: Move fdct function declarations to dct.hDiego Biurrun2013-02-09

* Drop DCTELEM typedefDiego Biurrun2013-01-22
| | | | | | It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Remove lowres video decodingMans Rullgard2012-04-21
| | | | | | | This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* libavcodec: Add ff_ prefix to j_rev_dct*Martin Storsjö2012-02-15

* Remove redundant filename self-references inside files.Diego Biurrun2011-11-08
| | | | Filenames are brittle across renames and add no useful information.
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Use full internal pathname in doxygen @file directives.Diego Biurrun2009-02-01
| | | | | | | Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk
