* avutil/channel_layout: add av_get_extended_channel_layoutMarton Balint2017-01-24
| | | | | | | | | | | | | | Return a channel layout and the number of channels based on the specified name. This function is similar to av_get_channel_layout(), but can also parse unknown channel layout specifications. Unknown channel layout specifications are a decimal number and a capital 'C' suffix, in order to not break compatibility with the lowercase 'c' suffix, which is used for a guessed channel layout with the specified number of channels.

* x86inc: Avoid using eax/rax for storing the stack pointerHenrik Gramner2017-01-09
| | | | | | | | | When allocating stack space with an alignment requirement that is larger than the current stack alignment we need to store a copy of the original stack pointer in order to be able to restore it later. If we chose to use another register for this purpose we should not pick eax/rax since it can be overwritten as a return value.
* avutil/tile: check clock_gettime at runtime for apple platformsWang Bin2017-01-09
| | | | | | | | | | | clock_gettime is avalible since macOS 10.12 and iOS 10.0. Because of weak linking, clock_gettime can be build without error with new macOS/iOS sdk, but the symbol may not exist on the target system. Explicitly checking the symbol is required. https://developer.apple.com/library/content/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html Signed-off-by: Wang Bin <wbsecg1@gmail.com> Signed-off-by: Steven Liu <lq@chinaffmpeg.org>

* avutil: fix data race in av_get_cpu_flags()Wan-Teh Chang2016-12-13
| | | | | | | | | | | | | | | | | | | | Make the one-time initialization in av_get_cpu_flags() thread-safe. The static variable |cpu_flags| in libavutil/cpu.c is read and written using normal load and store operations. These are considered as data races. The fix is to use atomic load and store operations. The fix can be verified by running the libavutil/tests/cpu_init.c test program under ThreadSanitizer: ./configure --toolchain=clang-tsan make libavutil/tests/cpu_init libavutil/tests/cpu_init There should be no warnings from ThreadSanitizer.

| | | | | | | | | P016 is the 16-bit variant of NV12 (planar luma, packed chroma), using two bytes per component. It may, and in fact is most likely to, be used in situations where there are less than 16 bits of data. It is the responsibility of the writer to zero out any unused LSBs.
