* compat: Use '-' instead of '/' for rc.exe optionsZiemowit Laski2023-02-131-5/+5
| | | | | | | | | | | | | When building FFMPEG in the MSYS environment under Windows, one must not use forward slashes ('/') for command-line options. It appears that the MSYS shell interprets these as absolute paths and then automatically rewrites them into equivalent Windows paths. For example, the '/nologo' switch below gets rewritten to something like 'C:/Program Files/Git/nologo', and this obviously breaks the build. Thankfully, most M$ tools accept dashes ('-') as well.

* compat/cuda: switch from powf to __powf intrinsicTimo Rothenpieler2022-09-031-1/+1
| | | | | | The powf builtin causes crashes on older clang, so manually implement the (faster) intrinsic. The code it spawns is identical to that of nvcc.

* compat/cuda: Change inclusion guardsAndreas Rheinhardt2019-08-052-6/+6
| | | | | | | | | | cuda_runtime.h as well as dynlink_loader.h used nonstandard inclusion guards with an AV_ prefix, although these files are not in an libav*/ path.

* build: add support for building CUDA files with clangRodger Combs2019-08-041-0/+131
| | | | | | | | | | | | | | | | This avoids using the CUDA SDK at all; instead, we provide a minimal reimplementation of the basic functionality that lavfi actually uses. It generates very similar code to what NVCC produces. The header contains no implementation code derived from the SDK. The function and type declarations are derived from the SDK only to the extent required to build a compatible implementation. This is generally accepted to qualify as fair use. Because this option does not require the proprietary SDK, it does not require the "--enable-nonfree" flag in configure. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

* compat/avisynth: update headersStephen Hutchinson2019-05-044-162/+415
| | | | | | | As part of the update, it is now possible to test 32-bit GCC builds of AviSynth+ with FFmpeg by using the AVS_WIN32_GCC32 define. Due to different calling conventions between MSVC and GCC regarding 32-bit Windows, this is unfortunately necessary.

* compat: remove in-tree NVidia headersTimo Rothenpieler2018-02-275-4918/+19
| | | | | | | | | | | | | | | | External headers are no longer welcome in the ffmpeg codebase because they increase the maintenance burden. However, in the NVidia case the vanilla headers need some modifications to be usable in ffmpeg therefore we still provide them, but in a separate repository. The external headers can be found at https://git.videolan.org/?p=ffmpeg/nv-codec-headers.git Fate-source is updated because of the deleted files, and dynlink_loader.h license headers were updated with the standard FFmpeg headers.

* w32pthreads: always use Vista+ API, drop XP supportwm42017-12-261-256/+10
| | | | | | | | | | | This removes the XP compatibility code, and switches entirely to SWR locks, which are available starting at Windows Vista. This removes CRITICAL_SECTION use, which allows us to add PTHREAD_MUTEX_INITIALIZER, which will be useful later. Windows XP is hereby not a supported build target anymore. It was decided in a project vote that this is OK.

| | | | | | | | | | | | | | | | | | | | This avoids having to use either "dumpbin -headers" to find out the current architecture, or pass $ARCH from configure to deduce it. When configuring with --disable-asm, ARCH is equal to "c", which doesn't give any indication of what symbol prefix is to be used. Signed-off-by: Martin Storsjö <martin@martin.st>
