* hwcontext_dxva2: support D3D9Exwm42017-02-13
| | | | | | | | | | D3D9Ex uses different driver paths. This helps with "headless" configurations when no user logs in. Plain D3D9 device creation will fail if no user is logged in, while it works with D3D9Ex. Signed-off-by: Anton Khirnov <anton@khirnov.net> Merges Libav commit c2f97f0508708.
* AVFrame: add an opaque_ref fieldwm42017-02-13
| | | | | | | | | | | | | | | | | This is an extended version of the AVFrame.opaque field, which can be used to attach arbitrary user information to an AVFrame. The usefulness of the opaque field is rather limited, because it can store only up to 32 bits of information (or 64 bit on 64 bit systems). It's not possible to set this field to a memory allocation, because there is no way to deallocate it correctly. The opaque_ref field circumvents this by letting the user set an AVBuffer, which makes the user data refcounted. Signed-off-by: Anton Khirnov <anton@khirnov.net> Merges Libav commit 04f3bd349651.
* Revert "avutil/hwcontext_vaapi: fix SEGV in vaTerminate when vaInitialize fails"Mark Thompson2017-02-05
| | | | | | | | | | | The original code is correctly following the API - vaTerminate() must be called to free the resources of a VADisplay after it is created by any of the vaGetDisplay*() calls; it is not necessary to have successfully called vaInitialize() on it. The segfaults which prompted this change must therefore be bugs in libva or the driver it loads. This reverts commit 3606602f1137552ea54f2c259eb140c1e3c026d4.

| * libavutil: Always use some GCC style attributes on clangMartin Storsjö2016-07-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang normally disguises as GCC (defining __GNUC__), and thus get all the normal GCC specific attributes. Clang can also work as a drop-in replacement for MSVC, and in these cases, it doesn't define __GNUC__, but defines _MSC_VER instead. Even in these setups, it still supports the GCC style attributes, thus use them, especially where there isn't any MSVC specific version, or where the MSVC specific version doesn't work on clang (for DECLARE_ASM_CONST).

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
