2019-06-18Fix timestamp overflow issuesYue Chen
- Save the initial user-specified timestamp and rebase all further timestamps by this value. This makes libvpx internal timestamps to always start from zero, regardless of the user's timestamps. - Calculate reduced timestamp conversion ratio and use it to convert user's timestamps to libvpx internal timestamps and back. The effect of this is that integer overflow due to multiplication doesn't happen for a much longer time. BUG=webm:701 Change-Id: Ic6f5eacd9a7c21b95707d31ee2da77dc8ac7dccf

2017-09-06Remove support for stdatomic.h.Peter Boström
This header doesn't build on g++ v6 as it's a C and not C++ header (_Atomic is not a keyword in C++11). Since the C and C++ invocations cannot be guaranteed to point to the same underlying atomic_int implementation, remove support for them and use compiler intrinsics instead.

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).

2016-08-10Align thread entry point stackAleksey Vasenev
_beginthreadex does not align the stack on 16-byte boundary as expected by gcc. On x86 targets, the force_align_arg_pointer attribute may be applied to individual function definitions, generating an alternate prologue and epilogue that realigns the run-time stack if necessary. This supports mixing legacy codes that run with a 4-byte aligned stack with modern codes that keep a 16-byte stack for SSE compatibility. https://gcc.gnu.org/onlinedocs/gcc/x86-Function-Attributes.html Change-Id: Ie4e4ab32948c238fa87054d5664189972ca6708e Signed-off-by: Aleksey Vasenev <margtu-fivt@ya.ru>
