* hwcontext_vaapi: Add support for mapping to DRM objectsMark Thompson2017-10-09
| | | | Uses vaExportSurfaceHandle() from libva2.
* hwcontext: Perform usual initialisation on derived device contextsMark Thompson2017-10-09
| | | | | | | The initialisation should be common. For libmfx, it was previously happening in the derivation function and this moves it out. For VAAPI, it fixes some failures when deriving from a DRM device because this initialisation did not run.
* hwcontext_vaapi: Set message callbacks on internally-created devicesMark Thompson2017-10-09
| | | | | The message callbacks are library-safe in libva2, so we can now use them.
* hwcontext_vaapi: Factorise out common connection codeMark Thompson2017-10-09
| | | | | This was duplicated between normal device creation and creation by derivation from a DRM device.

* | lavu/timer.h: add Linux Perf API supportClément Bœsch2017-09-08
| | | | | | | | | | | | | | | | | | | | | | | | Refer to "checkasm: use perf API on Linux ARM*" commit for the rationale. The implementation is somehow duplicated with checkasm, but so is the current usage of AV_READ_TIME(). Until these implementations and heuristics are made consistent, I don't see a way of sharing that code. Note: when using libavutil/timer.h, it is now important to include before any other include due to the _GNU_SOURCE requirement.
* | lavu/tests: move timer.h include earlierClément Bœsch2017-09-08
| | | | | | | | | | In the next commit, timer.h will require a _GNU_SOURCE to be set before including system headers. This commit prevents compilation failures.
* | lavu/tests/des: rename crypt to crypt_refClément Bœsch2017-09-08

* | d3d11va: Check WINAPI_FAMILY instead of HAVE_LOADLIBRARYMartin Storsjö2017-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | imgutils: add function to clear an image to blackwm42017-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
