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.

The getenv function doesn't exist there. In Visual Studio 2012, the function still existed in the link libraries even though it was hidden in the headers, but in the 2013 version it has been removed from the link libraries as well. Change-Id: Iea6289a698fa1788e906f5aabb6fddda3675815b

2013-11-20Support for extended feature flags enumeration leaf in CPUID instructionErik Niemeyer
This CL fixes an overcite with the AVX2 support CL previously merged (Change-Id: Idc03f3fca4bf2d0afd33631ea1d3caf8fc34ec29) that prevented runtime execution of AVX2 code in WebM. Background: Starting with the Sandybridge processor, the CPUID instruction was enhanced to add various extended feature flag enumeration leaves. Reading these leaves requires an additional input value for the CPUID instruction which is stored in ECX. This change adds this second input value for all ARCH_X86 and ARCH_x86_64 targets to the CPUID macros, allowing checks of EBX bit 5 for AVX2 support. This capability will be required moving forward to check for future processor features. Change-Id: Ie9d872bc9ff68dad4b6578e4544e4dfd0ae26c36

2012-11-07Rough merge of master into experimentalJohn Koleszar
Creates a merge between the master and experimental branches. Fixes a number of conflicts in the build system to allow *either* VP8 or VP9 to be built. Specifically either: $ configure --disable-vp9 $ configure --disable-vp8 --disable-unit-tests VP9 still exports its symbols and files as VP8, so that will be resolved in the next commit. Unit tests are broken in VP9, but this isn't a new issue. They are fixed upstream on origin/experimental as of this writing, but rebasing this merge proved difficult, so will tackle that in a second merge commit.

2012-06-20Clean Android build defaultsJohann
Disable unit-tests. The logging in GTest would need to be adjusted. Restructure ARM cpu detection. Flatten if-else logic. Change #if defined(HAVE_*) to #if HAVE_* because we only need to check for features that the library was actually built with. This should have been harmless, as disabled feature sets wouldn't have any features to call. Change-Id: Iea21aa42ce5f049c53ca0376d25bcd0f36f38284
2012-06-20Enables building examples with Android NDKAttila Nagy
Soft enable runtime cpu detect for armv7-android target, so that it can be disabled and remove dependency on 'cpufeatures' lib. Change the arm_cpu_caps implementation selection such that 'no rtcd' takes precedence over system type. Switch to use -mtune instead of -mcpu. NDK was complaining about -mcpu=cortex-a8 conflicting with -march=armv7-a, not sure why. Add a linker flag to fix some cortex-a8 bug, as suggested by NDK Dev Guide. Examples: Configure for armv7+neon: ./configure --target=armv7-android-gcc \ --sdk-path=/path/to/android/ndk \ --disable-runtime-cpu-detect \ --enable-realtime-only \ --disable-unit-tests ...armv7 w/o neon: ./configure --target=armv7-android-gcc \ --sdk-path=/path/to/android/ndk \ --disable-runtime-cpu-detect \ --enable-realtime-only \ --disable-neon \ --cpu=cortex-a9 \ --disable-unit-tests Change-Id: I37e2c0592745208979deec38f7658378d4bd6cfa
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
2012-05-23asm_*_offsets to define variables as constantsAlpha Lam
This change is to allow obj_int_extract to extract all integers in the data segment. With the const keyword these variables are forced into the .rodata segment even for zero variable value. We had a problem before that zero valueed variables would get assigned to BSS segment that fooled obj_int_extract to give incorrect values. Change-Id: Icd94f80a8ab356879894ca508bf132d20b865299
2012-05-23Make libvpx Chromium build friendlyAlpha Lam

Original patch by Ginn Chen <ginn.chen@oracle.com> against libvpx v0.9.0.

2012-03-15WebM Experimental Codec Branch SnapshotYaowu Xu
This is a code snapshot of experimental work currently ongoing for a next-generation codec. The codebase has been cut down considerably from the libvpx baseline. For example, we are currently only supporting VBR 2-pass rate control and have removed most of the code relating to coding speed, threading, error resilience, partitions and various other features. This is in part to make the codebase easier to work on and experiment with, but also because we want to have an open discussion about how the bitstream will be structured and partitioned and not have that conversation constrained by past work. Our basic working pattern has been to initially encapsulate experiments using configure options linked to #IF CONFIG_XXX statements in the code. Once experiments have matured and we are reasonably happy that they give benefit and can be merged without breaking other experiments, we remove the conditional compile statements and merge them in. Current changes include: * Temporal coding experiment for segments (though still only 4 max, it will likely be increased). * Segment feature experiment - to allow various bits of information to be coded at the segment level. Features tested so far include mode and reference frame information, limiting end of block offset and transform size, alongside Q and loop filter parameters, but this set is very fluid. * Support for 8x8 transform - 8x8 dct with 2nd order 2x2 haar is used in MBs using 16x16 prediction modes within inter frames. * Compound prediction (combination of signals from existing predictors to create a new predictor). * 8 tap interpolation filters and 1/8th pel motion vectors. * Loop filter modifications. * Various entropy modifications and changes to how entropy contexts and updates are handled. * Extended quantizer range matched to transform precision improvements. There are also ongoing further experiments that we hope to merge in the near future: For example, coding of motion and other aspects of the prediction signal to better support larger image formats, use of larger block sizes (e.g. 32x32 and up) and lossless non-transform based coding options (especially for key frames). It is our hope that we will be able to make regular updates and we will warmly welcome community contributions. Please be warned that, at this stage, the codebase is currently slower than VP8 stable branch as most new code has not been optimized, and even the 'C' has been deliberately written to be simple and obvious, not fast. The following graphs have the initial test results, numbers in the tables measure the compression improvement in terms of percentage.
