* libavutil: Add saturating subtraction functionsAndrew D'Addesio2017-12-04
| | | | | | | | | Add av_sat_sub32 and av_sat_dsub32 as the subtraction analogues to av_sat_add32/av_sat_dadd32. Also clarify the formulas for dadd32/dsub32. Signed-off-by: Andrew D'Addesio <modchipv12@gmail.com>

| | | | | | The macro was added in 43171a2a738f5114768d34a7278e56e5fde714bc, but I forgot to add it to the DJGPP architecture in that change. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* | hwcontext_vaapi: Do not assume that sw_format is transferableMark Thompson2017-11-26
| | | | | | | | | | | | 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.
* | hwcontext_d3d11va: properly reset values after release/closeJan Ekström2017-11-25
| | | | | | | | | | | | | | | | Makes the uninit function re-entrable, which can be a common case when an API user first tries to initialize its context, fails, and then finally unrefs the AVHWDevice. Fixes a crash reported by sm2345 on IRC.
* | hwcontext_opencl: Reset internal command queue on device_uninitMark Thompson2017-11-25
| | | | | | | | device_uninit can be called twice if device_init fails.
* | hwcontext_d3d11: Log adapter details on device creationMark Thompson2017-11-25
| | | | | | | | This is helpful to know what device has actually been used.
* | lavu/pixfmt: Remove gap in the middle of enum AVPixelFormatMark Thompson2017-11-25
| | | | | | | | | | | | | | | | This was added for compatibility with libav, by leaving a space for formats added in libav to be merged. Since that feature has been removed, we don't need a gap here. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc>
* | lavu,lavfi,ffmpeg: Remove experimental OpenCL APIMark Thompson2017-11-22
| | | | | | | | | | | | | | | | | | | | | | 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 Thompson2017-11-22
| | | | | | | | | | | | | | | | 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.
* | hwcontext_opencl: D3D11 to OpenCL mappingMark Thompson2017-11-22
| | | | | | | | Using cl_khr_d3d11_sharing and cl_intel_d3d11_nv12_media_sharing.
* | hwcontext_opencl: DXVA2 to OpenCL mappingMark Thompson2017-11-22
| | | | | | | | Using cl_khr_dx9_media_sharing.
* | hwcontext_opencl: QSV to OpenCL mapping for Intel Media SDKMark Thompson2017-11-22
| | | | | | | | | | Uses the cl_intel_va_api_media_sharing extension, which supports only NV12 surfaces and only mapping from QSV to OpenCL.

* | Avoid corrupting diagnostic state with _Pragma changes.Dale Curtis2017-11-14
| | | | | | | | | | | | | | | | | | | | | | The macros for ICC and MSVC correctly push and pop the diagnostic state of the compiler when disabling deprecation warnings. The ones for clang/gcc should do the same. Without this, if a blanket deprecation warning is applied to the code base it'll be flipped back on incorrectly with FF_ENABLE_DEPRECATION_WARNINGS.

* | Fix missing used attribute for inline assembly variablesThomas Köppe2017-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | Variables used in inline assembly need to be marked with attribute((used)). Static constants already were, via the define of DECLARE_ASM_CONST. But DECLARE_ALIGNED does not add this attribute, and some of the variables defined with it are const only used in inline assembly, and therefore appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks variables as used. This change makes FFMPEG work with Clang's ThinLTO. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| | | | | | | | | | | | | | | | | | We currently only have exported data symbols within libavcodec, but the concept is easy to extend to other libraries if necessary.
