* vo_gpu: hwdec_dxva2dxgi: initial implementationJames Ross-Gowan2018-01-061-0/+4
| | | | | | | | | | | | | This enables DXVA2 hardware decoding with ra_d3d11. It should be useful for Windows 7, where D3D11VA is not available. Images are transfered from D3D9 to D3D11 using D3D9Ex surface sharing[1]. Following Microsoft's recommendations, it uses a queue of shared surfaces, similar to Microsoft's ISurfaceQueue. This will hopefully prevent surface sharing from impacting parallelism and allow multiple D3D11 frames to be in-flight at once.

* hwdec: document a forgotten parameterwm42017-12-111-0/+1
| | | | Add the "all" value to the --gpu-hwdec-interop help output.
* vo_gpu: make it possible to load multiple hwdec interop driverswm42017-12-011-66/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the VO<->decoder interface capable of supporting multiple hwdec APIs at once. The main gain is that this simplifies autoprobing a lot. Before this change, it could happen that the VO loaded the "wrong" hwdec API, and the decoder was stuck with the choice (breaking hw decoding). With the change applied, the VO simply loads all available APIs, so autoprobing trickery is left entirely to the decoder. In the past, we were quite careful about not accidentally loading the wrong interop drivers. This was in part to make sure autoprobing works, but also because libva had this obnoxious bug of dumping garbage to stderr when using the API. libva was fixed, so this is not a problem anymore. The --opengl-hwdec-interop option is changed in various ways (again...), and renamed to --gpu-hwdec-interop. It does not have much use anymore, other than debugging. It's notable that the order in the hwdec interop array ra_hwdec_drivers[] still matters if multiple drivers support the same image formats, so the option can explicitly force one, if that should ever be necessary, or more likely, for debugging. One example are the ra_hwdec_d3d11egl and ra_hwdec_d3d11eglrgb drivers, which both support d3d11 input. vo_gpu now always loads the interop lazily by default, but when it does, it loads them all. vo_opengl_cb now always loads them when the GL context handle is initialized. I don't expect that this causes any problems. It's now possible to do things like changing between vdpau and nvdec decoding at runtime. This is also preparation for cleaning up vd_lavc.c hwdec autoprobing. It's another reason why hwdec_devices_request_all() does not take a hwdec type anymore.
* vd_lavc: prefer nvdec over vdpau with --hwdec=autowm42017-11-301-3/+3
| | | | | | | | | | | | | | | | nvdec aka cuvid aka cuda should work much better than vdpau, and support newer codecs (such as vp9), and more advanced surface formats (like 10 bit). This requires moving the d3d hwaccels in the autoprobe order, since on Windows, d3d decoding should be preferred over nvidia proprietary stuff. Users of older drivers will need to force --hwdec=vdpau, since it could happen that the vo_gpu cuda hwdec interop loads (so the vdpau interop is not loaded), but the hwdec itself doesn't work. I expect this does not break AMD (which still needs vdpau for vo_gpu interop, until libva is fixed so it can fully support AMD).
* vo_gpu: remove hwdec_vaglx interopwm42017-11-301-3/+0
| | | | | | This has stopped being useful a long time ago, and it's the only GPL source file in the vo_gpu source directories. Recently it wasn't even loaded at all, unless you forced loading it.
* vo_gpu: d3d11: initial implementationJames Ross-Gowan2017-11-071-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* vd_lavc: remove need for duplicated cuda GL interop backendwm42017-10-301-1/+0
| | | | | | | This is just a dumb consequence of HWDEC_ types somehow being part of both decoder and VO. Obviously, the VO should only care about supporting specific hardware surface types or providing specific device types, but until they are separated, stupid unintuitive mismatches will occur.
* vd_lavc: add support for nvdec hwaccelwm42017-10-281-0/+2
| | | | | | | | See manpage additions. (In ffmpeg-mpv and Libav, this is still called "cuvid". Libav won't work yet, because it has no frame params support yet, but this could get fixed soon.)
* Add DRM_PRIME Format Handling and Display for RockChip MPP decodersLionel CHAZALLON2017-10-231-0/+7
| | | | | | | | | | | This commit allows to use the AV_PIX_FMT_DRM_PRIME newly introduced format in ffmpeg that allows decoders to provide an AVDRMFrameDescriptor struct. That struct holds dmabuf fds and information allowing zerocopy rendering using KMS / DRM Atomic. This has been tested on RockChip ROCK64 device.
* vo_opengl: refactor into vo_gpuNiklas Haas2017-09-211-0/+239
This is done in several steps: 1. refactor MPGLContext -> struct ra_ctx 2. move GL-specific stuff in vo_opengl into opengl/context.c 3. generalize context creation to support other APIs, and add --gpu-api 4. rename all of the --opengl- options that are no longer opengl-specific 5. move all of the stuff from opengl/* that isn't GL-specific into gpu/ (note: opengl/gl_utils.h became opengl/utils.h) 6. rename vo_opengl to vo_gpu 7. to handle window screenshots, the short-term approach was to just add it to ra_swchain_fns. Long term (and for vulkan) this has to be moved to ra itself (and vo_gpu altered to compensate), but this was a stop-gap measure to prevent this commit from getting too big 8. move ra->fns->flush to ra_gl_ctx instead 9. some other minor changes that I've probably already forgotten Note: This is one half of a major refactor, the other half of which is provided by rossy's following commit. This commit enables support for all linux platforms, while his version enables support for all non-linux platforms. Note 2: vo_opengl_cb.c also re-uses ra_gl_ctx so it benefits from the --opengl- options like --opengl-early-flush, --opengl-finish etc. Should be a strict superset of the old functionality. Disclaimer: Since I have no way of compiling mpv on all platforms, some of these ports were done blindly. Specifically, the blind ports included context_mali_fbdev.c and context_rpi.c. Since they're both based on egl_helpers, the port should have gone smoothly without any major changes required. But if somebody complains about a compile error on those platforms (assuming anybody actually uses them), you know where to complain.
