* commit '95c0cec03acec0a80cc1c7db48f3b2355d9e767b': idctdsp: Add global function pointers for {add|put}_pixels_clamped functions Conflicts: libavcodec/arm/idctdsp_init_arm.c libavcodec/dct.h libavcodec/idctdsp.c libavcodec/jrevdct.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
2014-09-03idctdsp: Add global function pointers for {add|put}_pixels_clamped functionsDiego Biurrun
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.
2014-05-20avcodec/fate-idct8x8: Defined behavior: eliminate negative left-shifts.Katerina Barone-Adesi
The original code left-shifts negative values, which is undefined in the C99 specification (the one used during normal FFmpeg 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 Signed-off-by: Michael Niedermayer <michaelni@gmx.at> The assembly generated by gcc is unchanged by this commit

2013-01-23Drop DCTELEM typedefDiego Biurrun
It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2012-04-23lowres2 support.Michael Niedermayer
The new lowres support is limited to decoders where lowres decoding is possible in high quality. I was not able to measure any speed difference, but if one is found the 2-3 lines that might affect speed can be made compile time conditional Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2012-04-21Remove lowres video decodingMans Rullgard
This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>

Filenames are brittle across renames and add no useful information.
