Martin Storsjö	1912973a2d	d3d11va: Check WINAPI_FAMILY instead of HAVE_LOADLIBRARY 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.

wm4	cfc9e7c94e	hwcontext_d3d11va: add option to enable debug mode Basically copied from VLC (LGPL): http://git.videolan.org/?p=vlc.git;a=blob;f=modules/video_output/win32/direct3d11.c;h=e9fcb83dcabfe778f26e63d19f218caf06a7c3ae;hb=HEAD#l1482 http://git.videolan.org/?p=vlc.git;a=blob;f=modules/codec/avcodec/d3d11va.c;h=85e7d25caebc059a9770da2ef4bb8fe90816d76d;hb=HEAD#l599 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	8 years ago
wm4	5030e3856c	dxva: support DXGI_FORMAT_420_OPAQUE decoding 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>	8 years ago
wm4	98d73e4174	hwcontext_d3d11va: allocate staging texture lazily Makes dealing with formats that can not be used for staging textures easier (DXGI_FORMAT_420_OPAQUE). It also saves memory if the staging texture is never needed, so this is a good thing. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	8 years ago
wm4	086321c612	hwcontext_d3d11va: fix crash on frames_init failure It appears in this case, frames_ininit is called twice (once by av_hwframe_ctx_init(), and again by unreffing the frames ctx ref). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	8 years ago
Martin Storsjö	fd1ffa1f10	d3d11va: Link directly to dxgi.dll and d3d11.dll functions if LoadLibrary is unavailable When targeting the UWP API subset, the LoadLibrary function is not available (and the fallback, LoadPackagedLibrary, can't be used to load system DLLs). In these cases, link directly to the functions in the DLLs instead of trying to load them dynamically at runtime. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago
wm4	fff90422d1	lavu: add new D3D11 pixfmt and hwcontext 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. Frame upload code untested. Significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Signed-off-by: Diego Biurrun <diego@biurrun.de>	8 years ago
