* options: change option macros and all option declarationswm42020-03-181-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change all OPT_* macros such that they don't define the entire m_option initializer, and instead expand only to a part of it, which sets certain fields. This requires changing almost every option declaration, because they all use these macros. A declaration now always starts with {"name", ... followed by designated initializers only (possibly wrapped in macros). The OPT_* macros now initialize the .offset and .type fields only, sometimes also .priv and others. I think this change makes the option macros less tricky. The old code had to stuff everything into macro arguments (and attempted to allow setting arbitrary fields by letting the user pass designated initializers in the vararg parts). Some of this was made messy due to C99 and C11 not allowing 0-sized varargs with ',' removal. It's also possible that this change is pointless, other than cosmetic preferences. Not too happy about some things. For example, the OPT_CHOICE() indentation I applied looks a bit ugly. Much of this change was done with regex search&replace, but some places required manual editing. In particular, code in "obscure" areas (which I didn't include in compilation) might be broken now. In wayland_common.c the author of some option declarations confused the flags parameter with the default value (though the default value was also properly set below). I fixed this with this change.
* vo: make swapchain-depth option generic for all VOsAnton Kindestam2019-09-281-2/+2

* vo_gpu: d3d11: implement tex_download()James Ross-Gowan2018-02-131-12/+0
| | | | | | | This allows the new GPU screenshot functionality introduced in 9f595f3a80ee to work with the D3D11 backend. It replaces the old window screenshot functionality, which was shared between D3D11 and ANGLE. The old code can be removed, since it's not needed by ANGLE anymore either.
* vo_gpu: move d3d11_screenshot to shared codeJames Ross-Gowan2017-11-071-80/+6
| | | | This can be used by the ANGLE backend and ra_d3d11.
* vo_gpu: d3d11: initial implementationJames Ross-Gowan2017-11-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new RA/vo_gpu backend that uses Direct3D 11. The GLSL generated by vo_gpu is cross-compiled to HLSL with SPIRV-Cross. What works: - All of mpv's internal shaders should work, including compute shaders. - Some external shaders have been tested and work, including RAVU and adaptive-sharpen. - Non-dumb mode works, even on very old hardware. Most features work at feature level 9_3 and all features work at feature level 10_0. Some features also work at feature level 9_1 and 9_2, but without high-bit- depth FBOs, it's not very useful. (Hardware this old is probably not fast enough for advanced features anyway.) Note: This is more compatible than ANGLE, which requires 9_3 to work at all (GLES 2.0,) and 10_1 for non-dumb-mode (GLES 3.0.) - Hardware decoding with D3D11VA, including decoding of 10-bit formats without truncation to 8-bit. What doesn't work / can be improved: - PBO upload and direct rendering does not work yet. Direct rendering requires persistent-mapped PBOs because the decoder needs to be able to read data from images that have already been decoded and uploaded. Unfortunately, it seems like persistent-mapped PBOs are fundamentally incompatible with D3D11, which requires all resources to use driver- managed memory and requires memory to be unmapped (and hence pointers to be invalidated) when a resource is used in a draw or copy operation. However it might be possible to use D3D11's limited multithreading capabilities to emulate some features of PBOs, like asynchronous texture uploading. - The blit() and clear() operations don't have equivalents in the D3D11 API that handle all cases, so in most cases, they have to be emulated with a shader. This is currently done inside ra_d3d11, but ideally it would be done in generic code, so it can take advantage of mpv's shader generation utilities. - SPIRV-Cross is used through a NIH C-compatible wrapper library, since it does not expose a C interface itself. The library is available here: https://github.com/rossy/crossc - The D3D11 context could be made to support more modern DXGI features in future. For example, it should be possible to add support for high-bit-depth and HDR output with DXGI 1.5/1.6.
* vo_gpu: angle: fix misleading struct nameJames Ross-Gowan2017-09-231-2/+2
| | | | This should have been renamed when it stopped being empty.
* vo_gpu: override ra_swapchain_fns for the d3d11 surfaceJames Ross-Gowan2017-09-221-89/+112
| | | | | ANGLE can take advantage of some of these when using the external swapchain-backed surface.

* context_angle: remove unused variableJames Ross-Gowan2017-08-201-2/+0
| | | | Unused since 16e0a3948288.

* vo_opengl: extract non-ANGLE specific D3D11 codeJames Ross-Gowan2017-08-171-232/+33
| | | | | | | | | | | | This extracts non-ANGLE specific code to d3d11_helpers.c, which is modeled after egl_helpers.c. Currently the only consumer is context_angle.c, but in future this may allow the D3D11 device and swapchain creation logic to be reused in other backends. Also includes small improvements to D3D11 device creation. It is now possible to create feature level 11_1 devices (though ANGLE does not support these,) and BGRA swapchains, which might be slightly more efficient than ARGB, since its the same format used by the compositor.
* context_angle: fix fallback to D3D9 deviceJames Ross-Gowan2017-05-161-30/+56
| | | | | | | | | This was broken in e0250b9604b2. In some cases, device creation will succeed, but creating an EGL context on the device will fail. With --angle-renderer=auto, it should try to create the context again on a D3D9 device. This fixes mpv in Windows Vista on VirtualBox for me.
* vo_opengl: add a generic EGL function loader functionwm42017-04-061-6/+1
| | | | | | | This is pretty trivial, but also quite annoying due to details like mismatching eglGetProcAddress() function signature (most callers just cast the function pointer), and ARM/Linux hacks. So move them all to one place.
* vo_opengl: angle: add --angle-flip to set the present modelJames Ross-Gowan2017-03-261-2/+28
| | | | | | | | DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL might be buggy on some hardware. Additionaly DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL might be supported on some Windows 7 systems with the platform update, but it might have poor performance. In these cases, the user might want to disable the use of DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL swap chains with --angle-flip=no.
* vo_opengl: angle: log the device/surface implementationJames Ross-Gowan2017-02-121-13/+27
| | | | | This should be useful for debugging, since otherwise it's hard to tell which implementation has been auto-detected or if any failed to init.
* vo_opengl: angle: rewrite with custom swap chainJames Ross-Gowan2017-02-071-230/+641
| | | | | | | | | | | | | This replaces the old backend that exclusively used EGL windowing with one that can also use ANGLE's ability to render to directly to a texture. The advantage of this is that it allows mpv to create the swap chain itself and this allows mpv to use a flip-mode swap chain on a HWND (which avoids problems with DirectComposition) and to use a longer swap chain that has six backbuffers by default (which reportedly fixes problems with rendering 24fps video on 24Hz monitors.) Also, "screenshot window" should now work on DXGI 1.2 and up (Windows 8 and up.)
* options: refactor how --opengl-dcomposition is declaredwm42017-01-201-1/+21
| | | | | | | | | | | | | | | | | vo_opengl used to have it as sub-option, which made it very hard to pass down option values to backends in a generic way (even if these options were completely backend-specific). For --opengl-dcomposition we used a VOFLAG to deal with this. Fortunately, sub-options are gone, and we can just add it as global option. Move the option to context_angle.c and add it as global option. I thought about adding a mechanism to let backends declare options, which would get magically picked up my m_config instead of having to add them to the global option list manually (similar to VO vo_driver.options), but decided against this complexity just for 1 or 2 backends. Likewise, it could have been added as a single option to avoid the boilerplate of an option struct, but then again there are probably going to be more angle suboptions, and it's cleaner.
* win32: build with -DINITGUIDJames Ross-Gowan2016-09-281-1/+0
| | | | | | | | | | | | We always want to use __declspec(selectany) to declare GUIDs, but manually including <initguid.h> in every file that used GUIDs was error-prone. Since all <initguid.h> does is define INITGUID and include <guiddef.h>, we can remove all references to <initguid.h> and just compile with -DINITGUID to get the same effect. Also, this partially reverts 622bcb0 by re-adding libuuid.a to the build, since apparently some GUIDs (such as GUID_NULL) are not declared in the source file, even when INITGUID is set.
* vo_opengl: angle: new opengl flag to control DirectCompositionAvi Halachmi (:avih)2016-08-251-2/+7
| | | | | On some systems DirectComposition might behave poorly. Add an opengl suboption flag 'dcomposition' (default=yes) which can disable it.
* vo_opengl: angle: use WARP if there are no hw adaptersJames Ross-Gowan2016-07-121-2/+45
| | | | | | | | | | | | | | | This should get mpv working on Windows 7 machines without hardware accelerated graphics adapters. It already worked on Windows 8 and up because those systems would silently fall back to WARP if there was no graphics hardware installed. The normal MPGL_CAP_SW flag is not set, so unlike other opengl backends, this will choose a software adapter even if opengl:sw is not specified. The reason for this is, unlike on Linux, where vo_xv and vo_x11 can be used, mpv on Windows does not have any VO to fall back on when hardware acceleration isn't available, so if software adapters are rejected, the user won't see any video output when using the default settings. WARP seems to perform quite well, so it should be used in this case.
* vo_opengl: angle: try D3D9 when D3D11 fails eglInitializeJames Ross-Gowan2016-07-111-7/+8
| | | | | This will happen when D3D11 is present on the machine but the supported feature level is too low.
* vo_opengl: angle: update the swapchain on resizeJames Ross-Gowan2016-07-041-1/+16
| | | | | | | | | | | | | This uses eglPostSubBufferNV to trigger ANGLE to check the window size and update the size of the swapchain to match, which is recommended here: https://groups.google.com/d/msg/angleproject/RvyVkjRCQGU/gfKfT64IAgAJ With the D3D11 backend, using eglPostSubBufferNV with a 0-sized update region will even skip the Present() call, meaning it won't block for a vsync period. Hopefully ANGLE will have a less hacky way of doing this in future. See the relevant ANGLE issue: http://anglebug.com/1438 Fixes #3301
* vo_opengl: angle: prevent DXGI hooking Alt+EnterJames Ross-Gowan2016-06-071-0/+73
| | | | | | | | | | When ANGLE is using D3D11 and not running in DirectComposition mode, DXGI will hook the video window's message loop and override Alt+Enter to trigger a transition to exclusive fullscreen mode (which doesn't even work with mpv's renderer for some reason.) This behaviour can be disabled by getting a pointer to the IDXGIFactory associated with the D3D11 device and calling MakeWindowAssociation with the appropriate flags.
* vo_opengl: angle: enable DirectCompositionJames Ross-Gowan2016-05-291-10/+22
| | | | | | This avoids a copy of the video image and lowers vsync jitter. Since there are now two options to add to the window_attribs list, it has been made dynamic.
* vo_opengl: angle: log extension stringwm42016-05-131-0/+4

* vo_opengl: angle: dynamically load ANGLEwm42016-05-111-0/+7
| | | | | | | | | | | | ANGLE is _really_ annoying to build. (Requires special toolchain and a recent MSVC version.) This results in various issues with people having trouble to build mpv against ANGLE (apparently linking it against a prebuilt binary doesn't count, or using binaries from potentially untrusted sources is not wanted). Dynamically loading ANGLE is going to be a huge convenience. This commit implements this, with special focus on keeping it source compatible to a normal build with ANGLE linked at build-time.
* vo_opengl: add an angle-es2 backendwm42016-05-101-1/+23
| | | | | | It forces es2 mode on ANGLE. Only useful for testing. Since the normal "angle" backend already falls back to es2 if es3 does not work, this new backend always exit when autoprobing it.
* vo_opengl: angle: avoid fullscreen FBO copy for flippingwm42016-05-051-1/+23
| | | | | | | In order to honor the differences between OpenGL and Direct3D coordinate systems, ANGLE uses a full FBO copy merely to flip the final frame vertically. This can be avoided with the EGL_ANGLE_surface_orientation extension.
* vo_opengl: angle: call eglTerminate()wm42016-05-051-0/+2
| | | | | | | | | | | | I hope that this does what we expect it does: destroy the EGLDisplay specific to our HDC. (Some implementations will terminate all EGL contexts in the whole process.) eglReleaseThread() merely calls eglMakeCurrent(0, 0, 0, 0), which is not enough. This commit also fixes the problem fixed with the previous commit, but I think both changes are needed to make our API usage clean.
* Change GPL/LGPL dual-licensed files to LGPLwm42016-01-191-12/+7
| | | | | | | | | | | Do this to make the license situation less confusing. This change should be of no consequence, since LGPL is compatible with GPL anyway, and making it LGPL-only does not restrict the use with GPL code. Additionally, the wording implies that this is allowed, and that we can just remove the GPL part.
