DirectShow, Media Foundation, DXVA, what?

问题 I'm tasked with revising an application which uses DirectShow for video rendering. The old application works fine, but it's starting to show age. As I have a gaming background, I figured I should just approach this as such. After having made a bunch of prototypes using different techniques, I was pretty sure I could pull of video-to-texture rendering and use DirectX to fulfill all the clients his requests. However, I'm now at the point I have to pick a technique to go with and I couldn't be

问题 I got a IDirect3DSurface9 from DXVA2 video decoder using hardware acceleration. I'm try to Render this hardware IDirect3DSurface9 on My Window via its handle. The following is my summary code. The first, I call dxva2_init(AVCodecContext *s, HWND hwnd) ; with hwnd is window's handle int dxva2_init(AVCodecContext *s, HWND hwnd) { InputStream *ist = (InputStream *)s->opaque; int loglevel = (ist->hwaccel_id == HWACCEL_AUTO) ? AV_LOG_VERBOSE : AV_LOG_ERROR; DXVA2Context *ctx; int ret; if (!ist-

How do I use Hardware accelerated video/H.264 decoding with directx 11 and windows 7?

I've been researching all day and not gotten very far. I'm on windows 7, using directx 11. (My final output is to be a frame of video onto a DX11 texture) I want to decode some very large H.264 video files, and the CPU (using libav) doesn't cut it. I've looked at the hwaccel capabilities of libav using DXVA2, but hit a road block when I need to create a IDirectXVideoDecoder, which can only be created with a D3D9 interface. (which I don't have using DX11) Whenever I've looked up DXVA documentation, it doesn't reference DX11, was this removed in DX10 or 11? (Can't find any confirmation of this,
