Wu Jianhua	326288c70a	avcodec: add D3D12VA hardware accelerated VP9 decoding The command below is how to enable d3d12va: ffmpeg -hwaccel d3d12va -i input.mp4 output.mp4 Signed-off-by: Wu Jianhua <toqsxw@outlook.com> Signed-off-by: Tong Wu <tong1.wu@intel.com>	11 months ago
Wu Jianhua	349ce30e4e	avcodec: add D3D12VA hardware accelerated H264 decoding The implementation is based on: https://learn.microsoft.com/en-us/windows/win32/medfound/direct3d-12-video-overview With the Direct3D 12 video decoding support, we can render or process the decoded images by the pixel shaders or compute shaders directly without the extra copy overhead, which is beneficial especially if you are trying to render or post-process a 4K or 8K video.

Andreas Rheinhardt	e35dfe864d	avcodec/avcodec: Add FFHWAccel, hide internals of AVHWAccel This commit is the AVHWAccel analogue of commit 20f972701806be20a77f808db332d9489343bb78: It moves the private fields of AVHWAccel to a new struct FFHWAccel extending AVHWAccel in an internal header (namely hwaccel_internal.h).

Martin Storsjö	a78f136f3f	configure: Use a separate config_components.h header for $ALL_COMPONENTS This avoids unnecessary rebuilds of most source files if only the list of enabled components has changed, but not the other properties of the build, set in config.h.

wm4	70143a3954	dxva: add support for new dxva2 and d3d11 hwaccel APIs This also adds support to avconv (which is trivial due to the new hwaccel API being generic enough). The new decoder setup code in dxva2.c is significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Merges Libav commit `f9e7a2f95a`. Also adds untested VP9 support. The check for DXVA2 COBJs is removed. Just update your MinGW to something newer than a 5 year old release. Signed-off-by: Diego Biurrun <diego@biurrun.de>	8 years ago
wm4	ab28108a36	dxva: preparations for new hwaccel API The actual hwaccel code will need to access an internal context instead of avctx->hwaccel_context, so add a new DXVA_CONTEXT() macro, that will dispatch between the "old" external and the new internal context. Also, the new API requires a new D3D11 pixfmt, so all places which check for the pixfmt need to be adjusted. Introduce a ff_dxva2_is_d3d11() function, which does the check. Merges Libav commit `4dec101acc`. Adds changes to vp9 over the Libav patch. Signed-off-by: Diego Biurrun <diego@biurrun.de>	8 years ago
Ronald S. Bultje	0c46641784	vp9: split out generic decoding skeleton interface API from VP9 types. This allows vp9dsp.h to only include the VP9 types header, and not the decoder skeleton interface which is for hardware decoders (dxva2/vaapi).	8 years ago
