If this doesn't happen, undefined * behavior will result. + * + * Special D3D interop considerations + * ---------------------------------- + * + * If OpenGL switches to fullscreen, most players give it access GPU access, + * which means DXVA2 hardware decoding in mpv won't work. This can be worked + * around by giving mpv access to Direct3D device, which it will then use to + * create a decoder. The device can be either the real device used for display, + * or a "blank" device created before switching to fullscreen. + * + * You can do this by adding "GL_MP_D3D_interfaces" to the additional extension + * string when calling mpv_opengl_cb_init_gl(). The get_proc_address callback + * should resolve a function named "glMPGetD3DInterface", which has the + * signature: "void* __stdcall glMPGetD3DInterface(const char* name)". If + * name is "IDirect3DDevice9", it should return a IDirect3DDevice9 pointer + * (or NULL if not available). libmpv will release this interface when it is + * done with it (usually when mpv_opengl_cb_uninit_gl() is called). New + * interface names can be added in the future. */ /** |
