* hwcontext_d3d11va: add missing stdint.h includeTimo Rothenpieler2017-11-17
| | | | This caused checkheaders to fail on cygwin on this file.
* 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.

| * Remove support for building for mingw32ce (Windows CE)Martin Storsjö2017-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The toolchain for this target is unmaintained since many years. While it has been continuously build tested on fate, it hasn't actually been tested at runtime since many, many years (and back then, only a few codecs in libavcodec were tested). So far, keeping support for it has been mostly effortless, but the compiler does seem to have issues with dllimported data symbols, ending up as internal compiler errors in some cases. Instead of jumping through further hoops to work around that, just remove the target. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | | | | | | | | | | On windows, the offset for the relocation doesn't get stored in the relocation itself, but as an unsigned immediate in the opcode.

| * imgutils: add function to clear an image to blackwm42017-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Black isn't always just memset(ptr, 0, size). Limited YUV in particular requires relatively non-obvious values, and filling a frame with repeating 0 bytes is disallowed in some contexts. With component sizes larger than 8 or packed YUV, this can become relatively complicated. So having a generic function for this seems helpful. In order to handle the complex cases in a generic way without destroying performance, this code attempts to compute a black pixel, and then uses that value to clear the image data quickly by using a function like memset. Common cases like yuv410p10 or rgba can't be handled with a simple memset, so there is some code to fill memory with 2/4/8 byte patterns. For the remaining cases, a generic slow fallback is used.

| | | | | | | | | | | | | | | | | | | | | | | | | | If using the winstore compat library, a fallback LoadLibrary function does exist, that only calls LoadPackagedLibrary though (which doesn't work for dynamically loading d3d11 DLLs). Therefore explicitly check the targeted API family instead. Make this check a reusable HAVE_* component which other parts of the libraries can check when necessary as well.

| * dxva: support DXGI_FORMAT_420_OPAQUE decodingwm42017-06-27
| | | | | | | | | | | | | | | | | | | | | | | | Some devices (some phones, apparently) will support only this opaque format. Of course this won't work with CLI, because copying data directly is not supported. Automatic frame allocation (setting AVCodecContext.hw_device_ctx) does not support this mode, even if it's the only supported mode. But since opaque surfaces are generally less useful, that's probably ok. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To be used with the new d3d11 hwaccel decode API. With the new hwaccel API, we don't want surfaces to depend on the decoder (other than the required dimension and format). The old D3D11VA pixfmt uses ID3D11VideoDecoderOutputView pointers, which include the decoder configuration, and thus is incompatible with the new hwaccel API. This patch introduces AV_PIX_FMT_D3D11, which uses ID3D11Texture2D and an index. It's simpler and compatible with the new hwaccel API. The introduced hwcontext supports only the new pixfmt.
