2014-06-12Use lrand48 on AndroidJohann
When building x86 assembly use lrand48 instead of the undocumented inlined _rand function. Android now supports rand() https://android-review.googlesource.com/97731 but only for new versions. Original workaround: https://gerrit.chromium.org/gerrit/15744 Change-Id: I130566837d5bfc9e54187ebe9807350d1a7dab2a

2014-05-21Renames x86_64 specific asm filesDeb Mukherjee
Renames all x86_64 specific assembly files to consistently end in _x86_64.asm. This will be useful for build systems to handle these files differently. All new 64-bit specific assembly files should use the new naming convention. Change-Id: I36c89584967c82ffc4088b1b5044ac15d2bb7536

2013-10-01Merge "Fix linker warnings for bilinear filters"Matthew Heaney
2013-10-01Fix linker warnings for bilinear filtersMatthew Heaney
The declaration of the bilinear filters specified an alignment clause in the implementation file but not in the header. This turned out to be harmless, but it did cause linker warnings to be emitted when building on Windows. The (extern) declaration in the header was changed, to match the declaration in the implementation. Change-Id: I44be89b1572fe9a50fa47a42e4db9128c4897b04

2012-10-08post-proc: deblock filter optimizationYunqing Wang
1. Algorithm modification: Instead of having same filter threshold for a whole frame, now we allow the thresholds to be adjusted for each macroblock. In current implementation, to avoid excessive blur on background as reported in issue480(http://code.google.com/p/webm/issues/detail?id=480), we reduce the thresholds for skipped macroblocks. 2. SSE2 optimization: As started in issue479(http://code.google.com/p/webm/issues/detail?id=479), the filter calculation was adjusted for better performance. The c code was also modified accordingly. This made the deblock filter 2x faster, and the decoder was 1.2x faster overall. Next, the demacroblock filter will be modified similarly. Change-Id: I05e54c3f580ccd427487d085096b3174f2ab7e86
2012-07-27Be consistent with SAD valuesJohann
SAD returns unsigned values. Make all the declarations the same. Remove bestsad initialization and check. It is always set to the result of a SAD call so it will never remain UINT_MAX Use ja instead of jg to test unsigned comparison instead of signed. Update test.

2012-07-02Add 0 offsets handling in SSSE3 sixtap_predict functionsYunqing Wang
This patch fixed issue 458 by calling copy function when both offsets are 0, which guarantees the SSSE3 functions output same result as the c function for all possible offsets. Change-Id: I209aec7a4c6b3362db2646a8887c1038493b6496
2012-06-11Fix pedantic compiler warningsJohn Koleszar
Allows building the library with the gcc -pedantic option, for improved portabilty. In particular, this commit removes usage of C99/C++ style single-line comments and dynamic struct initializers. This is a continuation of the work done in commit 97b766a46, which removed most of these warnings for decode only builds. Change-Id: Id453d9c1d9f44cc0381b10c3869fabb0184d5966

2012-01-30New RTCD implementationJohn Koleszar
This is a proof of concept RTCD implementation to replace the current system of nested includes, prototypes, INVOKE macros, etc. Currently only the decoder specific functions are implemented in the new system. Additional functions will be added in subsequent commits. Overview: RTCD "functions" are implemented as either a global function pointer or a macro (when only one eligible specialization available). Functions which have RTCD specializations are listed using a simple DSL identifying the function's base name, its prototype, and the architecture extensions that specializations are available for. Advantages over the old system: - No INVOKE macros. A call to an RTCD function looks like an ordinary function call. - No need to pass vtables around. - If there is only one eligible function to call, the function is called directly, rather than indirecting through a function pointer. - Supports the notion of "required" extensions, so in combination with the above, on x86_64 if the best function available is sse2 or lower it will be called directly, since all x86_64 platforms implement sse2. - Elides all references to functions which will never be called, which could reduce binary size. For example if sse2 is required and there are both mmx and sse2 implementations of a certain function, the code will have no link time references to the mmx code. - Significantly easier to add a new function, just one file to edit. Disadvantages: - Requires global writable data (though this is not a new requirement) - 1 new generated source file. Change-Id: Iae6edab65315f79c168485c96872641c5aa09d55
