This is a debug tool used to detect bitstream error. On encoder side, it pushes each bit and probability into a queue before the bit is written into the Arithmetic coder. On decoder side, whenever a bit is read out from the Arithmetic coder, it pops up the reference bit and probability from the queue as well. If the two results do not match, this debug tool will report an error. This tool can be used to pin down the bitstream error precisely. By combining gdb's backtrace method, we can detect which module causes the bitstream error. Change-Id: I133a4371fafdd48c488f2ca47f9e395676c401f2

Added a new expt rect-tx to be used in conjunction with ext-tx. [rect-tx is a temporary config flag and will eventually be merged into ext-tx once it works correctly with all other experiments]. Added 4x8 and 8x4 tranforms for use initially with rectangular sub8x8 y blocks as part of this experiment. There is about a -0.2% BDRATE improvement on lowres, others pending. When var-tx is on rectangular transforms are currently not used. That will be enabled in a subsequent patch. Change-Id: Iaf3f88ede2740ffe6a0ffb1ef5fc01a16cd0283a

This commit bring all up-to-date changes from master that are applicable to nextgenv2. Due to the remove VP10 code in master, we had to cherry pick the following commits to get those changes: Add default flags for arm64/armv8 builds Allows building simple targets with sane default flags. For example, using the Android arm64 toolchain from the NDK: https://developer.android.com/ndk/guides/standalone_toolchain.html ./build/tools/make-standalone-toolchain.sh --arch=arm64 \ --platform=android-24 --install-dir=/tmp/arm64 CROSS=/tmp/arm64/bin/aarch64-linux-android- \ ~/libvpx/configure --target=arm64-linux-gcc --disable-multithread BUG=webm:1143 vpx_lpf_horizontal_4_sse2: Remove dead load.

Also allows use of --enable-shared when configuring for Mac OS X, producing a bare .dylib. Enabling the shared framework bumps the iOS deployment target to 8.0, the minimum required to support dynamic framework deployment in apps. When not using --enable-shared, a static library for iOS 6.0+ will still be built. Minimum version settings have been moved into ios-version.sh so they can be updated in a single place. As with the static build, unless header search paths are manually tweaked, users must add a VPX prefix on includes, such as: #include <VPX/vpx/vpx_decoder.h> A module map for headers is not yet included as inttypes.h is not modular; this means that VPX cannot be used directly in Swift code, but can still be pulled in through an Objective-C wrapper.

Up-sampled the reference frames to 8 times in each dimension using the 8-tap interpolation filter. In sub-pixel motion search, use the up-sampled reference frames to find the best matching blocks. This largely improved the motion search precision, and thus, improved the compression quality. There was no change in decoder side. Borg test and speed test results: 1. On derflr set, Overall PSNR gain: 1.306%, and SSIM gain: 1.512%. Average speed loss on derf set was 6.0%. 2. On stdhd set, Overall PSNR gain: 0.754%, and SSIM gain: 0.814%. On hevchd set, Overall PSNR gain: 0.465%, and SSIM gain: 0.527%. Speed loss on HD clips was 3.5%. Change-Id: I300ebaafff57e88914f3dedc8784cb21d316b04f

This commit adds a new configure option: --enable-better-hw-compatibility The purpose of the configure option is to provide information on known hardware decoder implementation bugs, so encoder implementers may choose to implement their encoders in a way to avoid triggering these decoder bugs. The WebM team were made aware of that a number of hardware decoders have trouble in handling the combination of scaled frame reference frame and 8x4 or 4x8 partitions. This commit added asserts to vp9 decoder, so when built with above configure option, the decoder can assert if an input bitstream triggers such decoder bug.
