* avutil/opt: Document actual behaviour of av_opt_copy a bit moreAndreas Rheinhardt2021-08-17
| | | | | | | | | In particular, document that av_opt_copy() always disentangles allocated options even on error; this guarantee is needed to e.g. properly free duplicated thread contexts in libavcodec on error.

* hwcontext_vulkan: use GPU memcpy when copying to system RAMLynne2021-08-14
| | | | This should speed it up significantly on systems where it matters.
* imgutils: expose av_image_copy_plane_uc_from()Lynne2021-08-14
| | | | | | | | | | | | The reason why the generic av_image_copy_uc_from() doesn't really fit in the case for Vulkan is because some planes may be copied via other methods (such as mapping GPU memory), and if they don't satisfy the strict alignment requirements, a gpu image->gpu buffer->cpu ram copy is performed. We need this for hwcontext_vulkan, and I think this will also be useful to API users like libplacebo who would rather not write a custom SIMD memcpy.
* avutil/mem: Correct av_calloc() documentationAndreas Rheinhardt2021-08-12

* avutil/mem: Reinline av_size_mult() internallyAndreas Rheinhardt2021-08-12
| | | | | | | | | | | | | Since 580e168a945b65100ec2c25433f33bfacfe9f7be, av_size_mult() is no longer inlined; on systems where interposing is a thing, this also inhibits the compiler from inlining said function into the internal callers of said function, although inlining such a small function is typically beneficial: With GCC 10.3 on Ubuntu x64 and -O3 this decreases the size of av_realloc_array from 91B to 23B, from 129B to 81B for av_realloc_f and from 77B to 23B for each of av_malloc_array, av_mallocz_array and av_calloc.

* avutil/error: Include macros.h for MKTAGAndreas Rheinhardt2021-07-29
| | | | | | | | | Up until now, including error.h alone does not make the AVERROR_* defines usable, because they just expand to something involving MKTAG, but without the header providing MKTAG. So include macros.h, the header providing MKTAG. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avutil/common, macros: Move several macros from common.h to macros.hAndreas Rheinhardt2021-07-29
| | | | | | | | | | | | common.h currently contains several things: Math macros, UTF-8 macros, other fundamental macros; furthermore it also contains miscellaneous math functions and it (directly and indirectly) includes lots of other headers. This commit moves the "other fundamental macros" to macros.h which is a more fitting place. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avutil/mips: Use $at as MMI macro temporary registerJiaxun Yang2021-07-28
| | | | | | | | | | | | | Some function had exceed 30 inline assembly register oprands limiation when using LOONGSON2 version of MMI macros. We can avoid that by take $at, which is register reserved for assembler, as temporary register. As none of instructions used in these macros is pseudo, it is safe to utilize $at here.

* x86/tx_float: correctly load the transform lengthLynne2021-07-18
| | | | | | | | The field is a standard field, yet we were loading it as if it was a quadword. This worked for forward transforms by chance, but broke when the transform was inverse. checkasm couldn't catch that because we only test forward transforms, which are identical to inverse transforms but with a different revtab.

| | | | | | | | | | | | This mostly reverts 785bfb1d7bb8de567c3aac1d9cc369b55ac9fb7b. But I also added some clarifications so that nobody mixes primaries with matrix again. SMPTE 240 and 170 primaires are the same, while matrix coeff. are different, because 240 is derived from 170's new primaries and white point while 170 uses BT.601 derived from BT.470 System M (yes, with Illuminant C) a.k.a.

* hwcontext_vulkan: dlopen libvulkanLynne2021-04-30
| | | | | | | | | | | | While Vulkan itself went more or less the way it was expected to go, libvulkan didn't quite solve all of the opengl loader issues. It's multi-vendor, yes, but unfortunately, the code is Google/Khronos QUALITY, so suffers from big static linking issues (static linking on anything but OSX is unsupported), has bugs, and due to the prefix system used, there are 3 or so ways to type out functions. Just solve all of those problems by dlopening it. We even have nice emulation for it on Windows.
