* 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.

| | | | | | | | | | | Remove the |checked| variable because the invalid value of -1 for |flags| can be used to indicate the same condition.

* libavutil/hwcontext_cuda: Support P010 and P016 formatsPhilip Langdale2016-11-22
| | | | | CUVID is now capable of returning 10bit and 12bit decoded content in P010/P016. Let's support transfering those formats.
* avutil: add P016 pixel formatPhilip Langdale2016-11-22
| | | | | | | | | 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.

* arm: Clear the gp register alias at the end of functionsMartin Storsjö2016-11-15
| | | | | | | | | | | | | | We reset .Lpic_gp to zero at the start of each function, which means that the logic within movrelx for clearing gp when necessary will be missed. This fixes using movrelx in different functions with a different helper register. This is cherry-picked from libav commit 824e8c284054f323f854892d1b4739239ed1fdc7. Signed-off-by: Ronald S.

| | | | | | | | | | | | | | | | | | | | | | The driver being used is detected inside av_hwdevice_ctx_init() and the quirks field then set from a table of known device. If this behaviour is unwanted, the user can also set the quirks field manually. Also adds the Intel i965 driver quirk (it does not destroy parameter buffers used in a call to vaRenderPicture()) and detects that driver to set it.
