|\ | | | | | | | | | | | | * commit 'f79d847400d218cfd0b95f10358fe6e65ec3c9c4': intreadwrite: Use the __unaligned keyword on MSVC for ARM and x86_64 Merged-by: James Almer <jamrial@gmail.com>
| * intreadwrite: Use the __unaligned keyword on MSVC for ARM and x86_64Martin Storsjö2016-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | AV_WN64 is meant for unaligned data, but the existing av_alias* unions (without a definition for the av_alias attribute - we don't have one for MSVC) indicate to the compiler that they would have sufficient alignment for normal access, i.e. the compiler is free to assume 8 byte alignment. On ARM, this makes sure that AV_WN64 (or two consecutive AV_WN32) is done with two str instructions instead of one strd. Signed-off-by: Martin Storsjö <martin@martin.st>

| * intreadwrite: Add intermediate variables in the byteswise AV_W*() macrosMartin Storsjö2016-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids issues with expanding the argument multiple times, and makes sure that it is of the right type for the following shifts. Even if the caller of a macro could be expected not to pass parameters that have side effects if expanded multiple times, these fallback codepaths are rarely, if ever, tested, so it is expected that such issues can arise. Thefore, for safety, make sure the fallback codepaths only expand the arguments once. Signed-off-by: Martin Storsjö <martin@martin.st>
| * libavutil: Use an intermediate variable in AV_COPY*UMartin Storsjö2016-07-31
| | | | | | | | | | | | | | | | | | | | | | If AV_RN and AV_WN are macros with multiple individual reads and writes, the previous version of the AV_COPYU macro would fail if the reads and writes overlap. This should not be any less efficient in any case, given a sensibly optimizing compiler. Signed-off-by: Martin Storsjö <martin@martin.st>

Normality Hypothesis Test: The null hypothesis formally tests if the population the sample represents is normally-distributed. For CS, when the normality hypothesis is True, the distribution of QH will have a mean close to 1.

Before this change, many fields were "public", but could be accessed via AVOption only. This meant they were effectively not public, but were present for documentation purposes, which was incredibly confusing at best.

* | 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).
