|\ | | | | | | | | | | | | * commit '85e10c0a9321bfe0d2afe0f3983ab6a8df6e3fba': intreadwrite: Use __unaligned in MSVC for ARM64 as well Merged-by: Mark Thompson <sw@jkqxz.net>

| | | | | | | | | | On ELF platforms such symbols needs to be flagged as functions with the correct visibility to please certain linkers in some scenarios.
* | x86inc: Use .rdata instead of .rodata on WindowsHenrik Gramner2018-01-201-0/+4
| | | | | | | | | | The standard section for read-only data on Windows is .rdata. Nasm will flag non-standard sections as executable by default which isn't ideal.
* | x86inc: Enable AVX emulation for floating-point pseudo-instructionsHenrik Gramner2018-01-201-0/+32
| | | | | | | | | | | | | | There are 32 pseudo-instructions for each floating-point comparison instruction, but only 8 of them are actually valid in legacy-encoded mode. The remaining 24 requires the use of VEX-encoded (v-prefixed) instructions and can therefore be disregarded for this purpose.

* | hwcontext_d3d11va: implement av_hwdevice_get_hwframe_constraints()wm42018-01-161-0/+33
| | | | | | | | | | | | | | D3D11 has rather fine grained per format capabilities for different uses that can be queried at runtime. Since we don't know what the user wants to do with the formats when av_hwdevice_get_hwframe_constraints() is called, we simply return all formats that have the most basic support.
* | hwcontext_vdpau: implement av_hwdevice_get_hwframe_constraints()wm42018-01-151-16/+39
| | | | | | | | | | | | | | | | | | | | | | In addition, this does not allow creating frames contexts with sw_format for which no known transfer formats exist. In theory, we should check whether the chroma format (i.e. the sw_format) is supported at all by the vdpau driver, but checking for transfer formats has the same effect. Note that the pre-existing code adds 1 to priv->nb_pix_fmts[i] for unknown reason, and some checks need to account for that to check for empty lists. They are not off-by-one errors.

* | lavc: replace and deprecate the lock managerwm42017-12-261-0/+2
| | | | | | | | | | | | | | Use static mutexes instead of requiring a lock manager. The behavior should be roughly the same before and after this change for API users which did not set the lock manager at all (except that a minor memory leak disappears).
* | w32pthreads: always use Vista+ API, drop XP supportwm42017-12-261-4/+0
| | | | | | | | | | | | | | | | | | | | | | 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.

* | x86inc: AVX-512 supportHenrik Gramner2017-12-241-33/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AVX-512 consists of a plethora of different extensions, but in order to keep things a bit more manageable we group together the following extensions under a single baseline cpu flag which should cover SKL-X and future CPUs: * AVX-512 Foundation (F) * AVX-512 Conflict Detection Instructions (CD) * AVX-512 Byte and Word Instructions (BW) * AVX-512 Doubleword and Quadword Instructions (DQ) * AVX-512 Vector Length Extensions (VL) On x86-64 AVX-512 provides 16 additional vector registers, prefer using those over existing ones since it allows us to avoid using `vzeroupper` unless more than 16 vector registers are required. They also happen to be volatile on Windows which means that we don't need to save and restore existing xmm register contents unless more than 22 vector registers are required. Big thanks to Intel for their support.

* | hwcontext_vaapi: Do not assume that sw_format is transferableMark Thompson2017-11-261-7/+14
| | | | | | | | | | | | Drivers can support a format for surfaces without also supporting it for images, so we can't assume that sw_format is usable for transfer. This would previously hit an assert in cases where it isn't.

* | lavu,lavfi,ffmpeg: Remove experimental OpenCL APIMark Thompson2017-11-225-1270/+0
| | | | | | | | | | | | | | | | | | | | | | This was added in early 2013 and abandoned several months later; as far as I can tell, there are no external users. Future OpenCL use will be via hwcontext, which requires neither special OpenCL-only API nor global state in libavutil. All internal users are also deleted - this is just the unsharp filter (replaced by unsharp_opencl, which is more flexible) and the deshake filter (no replacement).

* | hwcontext_opencl: DRM to OpenCL mapping for ARMMark Thompson2017-11-221-0/+263
| | | | | | | | | | | | | | | | Using cl_arm_import_memory. Unfortunately, despite this not being a standard extension, the function clImportMemoryARM() is not accessible via clGetExtensionFunctionAddressForPlatform(). This means that it has to be linked directly to the ARM OpenCL binary, so making a portable binary is not possible as it is with all other mapping extensions.
