2017-08-31Prevent data race from low-pass filter.Peter Boström
Makes main thread wait for the filter level to be picked to avoid a race between the LPF thread and update_reference_frames(). This also re-enables the failing tests under thread_sanitizer where this data race was detected. BUG=webm:1460 Change-Id: I7f5797142ea0200394309842ce3e91a480be4fbc
2017-08-31Add atomics to vp8 synchronization primitives.Peter Boström
Fixes issue on iPad Pro 10.5 (and probably other places) where threads are not properly synchronized. On x86 this data race was benign as load and store instructions are atomic, they were being atomic in practice as the program hasn't been observed to be miscompiled. Such guarantees are not made outside x86, and real problems manifested where libvpx reliably reproduced a broken bitstream for even just the initial keyframe. This was detected in WebRTC where this device started using multithreading (as its CPU count is higher than earlier devices, where the problem did not manifest as single-threading was used in practice). This issue was not detected under thread-sanitizer bots as mutexes were conditionally used under this platform to simulate the protected read and write semantics that were in practice provided on x86 platforms. This change also removes several mutexes, so encoder/decoder state is lighter-weight after this change and we do not need to initialize so many mutexes (this was done even on non-thread-sanitizer platforms where they were unused).

2017-08-15Clean up writing YUV files for debug purpose.Jerome Jiang
Change legacy vp8/9_write_yuv_frame to vpx_write_yuv_files. Delete some flags that can be enabled during build. To enable writing denoised YUV, use the following command line: CFLAGS='-DOUTPUT_YUV_DENOISED' ./configure --enable-vp9-temporal-denoising For skinmap, use CFLAGS='-DOUTPUT_YUV_SKINMAP' Change-Id: I236974ac8b3cf279d20c4dc7f6162d8b480b6528

2017-08-02vp8: Drop due to overshoot for non-screen content.Marco
For 1 pass CBR mode: Apply the logic for dropping (and re-adjusting rate control) due to large overshoot to the case of non-screen content when drop_frames_allowed is enabled. For the non-screen content case: add additional condition that rate correction factor is close to minimum state, and flag to constrain the frequency of the dropping. Also handle the case of temporal layers and multi-res encoding. Add some flags/counters to the layer context for temporal layers. For multi-res: drop due to overshoot is checked on lowest stream, and if overshoot is detected we force drops on all upper streams for that frame. This feature is to avoid large frame sizes on big content changes following low content period. No change in behavior for screen_content_mode = 2. Change-Id: I797ab236cbbf3b15cad439e9a227fbebced632e6

2017-07-19Earmark extra space for VSX.Han Shen
Backend specific optimization for PPC VSX reads 16 bytes, whereas arm neon / sse2 only reads <= 8 bytes. Although the extra bytes read are actually never used, this is not a warrant for groping around. Fixed by allocating more when building for VSX. This is reported by asan. Also note - PPC does have assembly that loads 64-bit content from memory - lxsdx loads one 64-bit doubleword (whereas lxvd2x loads two 64-bit doubleword) from memory. However, we only have "vec_vsx_ld" builtins that mapped to lxvd2x, no builtins to lxsdx. The only way to access lxsdx is through inline assembly, which does not fit well in the origin paradigm. Refer: vsx: vpx_tm_predictor_4x4_vsx @ third_party/libvpx/git_root/vpx_dsp/ppc/intrapred_vsx.c neon: vpx_tm_predictor_4x4_neon @ third_party/libvpx/git_root/vpx_dsp/arm/intrapred_neon_asm.asm sse2: tm_predictor_4x4 @ third_party/libvpx/git_root/vpx_dsp/x86/intrapred_sse2.asm BUG=b/63112600 Tested: asan tests passed.

the check for error correction being disabled was overriding the data length checks. this avoids returning incorrect information (width / height) for the decoded frame which could result in inconsistent sizes returned in to an application causing it to read beyond the bounds of the frame allocation.
