vo_opengl, vo_opengl_cb: better hwdec interop backend selection Introduce the --opengl-hwdec-interop option, which replaces --hwdec-preload. The new option allows explicit selection of the interop backend. This is relatively complex, and I would have preferred not to add this, but it's probably useful to debug certain problems. In exchange, the "new" option documents that pretty much any but the simplest use of it will not be forward compatible.

vo_opengl: separate hwdec context and mapping, port it to use ra This does two separate rather intrusive things: 1. Make the hwdec context (which does initialization, provides the device to the decoder, and other basic state) and frame mapping (getting textures from a mp_image) separate. This is more flexible, and you could map multiple images at once. It will help removing some hwdec special-casing from video.c. 2. Switch all hwdec API use to ra. Of course all code is still GL specific, but in theory it would be possible to support other backends. The most important change is that the hwdec interop returns ra objects, instead of anything GL specific. This removes the last dependency on GL-specific header files from video.c. I'm mixing these separate changes because both requires essentially rewriting all the glue code, so better do them at once. For the same reason, this change isn't done incrementally. hwdec_ios.m is untested, since I can't test it. Apart from superficial mistakes, this also requires dealing with Apple's texture format fuckups: they force you to use GL_LUMINANCE[_ALPHA] instead of GL_RED and GL_RG. We also need to report the correct format via ra_tex to the renderer, which is done by find_la_variant(). It's unknown whether this works correctly. hwdec_rpi.c as well as vo_rpi.c are still broken. (I need to pull my RPI out of a dusty pile of devices and cables, so, later.)

vo_gpu: d3d11: initial implementation 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.

vaapi: remove dependency on X11 There are at least 2 ways of using VAAPI without X11 (Wayland, DRM). Remove the X11 requirement from the decoder part and the EGL interop. This will be used by a following commit, which adds Wayland support. The worst about this is the decoder part, which includes a bad hack for using the decoder without any VO interop (also known as "vaapi-copy" mode). Separate the X11 parts so that they're self-contained. For the EGL interop code we do something similar (it's kept slightly simpler, because it essentially only has to translate between our silly MPGetNativeDisplay abstraction and the vaGetDisplay...() call).

vo_opengl: support new VAAPI EGL interop Should work much better than the old GLX interop code. Requires Mesa 11, and explicitly selecting the X11 EGL backend with: --vo=opengl:backend=x11egl Should it turn out that the new interop works well, we will try to autodetect EGL by default. This code still uses some bad assumptions, like expecting surfaces to be in NV12. (This is probably ok, because virtually all HW will use this format. But we should at least check this on init or so, instead of failing to render an image if our assumption doesn't hold up.) This repo was a lot of help: https://github.com/gbeauchesne/ffvademo The kodi code was also helpful (the magic FourCC it uses for EGL_LINUX_DRM_FOURCC_EXT are nowhere documented, and EGL_IMAGE_INTERNAL_FORMAT_EXT as used in ffvademo does not actually exist). (This is the 3rd VAAPI GL interop that was implemented in this player.)

client API, dxva2: add a workaround for OpenGL fullscreen issues This is basically a hack for drivers which prevent the mpv DXVA2 decoder glue from working if OpenGL is in fullscreen mode.

vo_opengl: separate hwdec context and mapping, port it to use ra This does two separate rather intrusive things: 1. Make the hwdec context (which does initialization, provides the device to the decoder, and other basic state) and frame mapping (getting textures from a mp_image) separate. This is more flexible, and you could map multiple images at once. It will help removing some hwdec special-casing from video.c. 2. Switch all hwdec API use to ra. Of course all code is still GL specific, but in theory it would be possible to support other backends. The most important change is that the hwdec interop returns ra objects, instead of anything GL specific. This removes the last dependency on GL-specific header files from video.c. I'm mixing these separate changes because both requires essentially rewriting all the glue code, so better do them at once. For the same reason, this change isn't done incrementally. hwdec_ios.m is untested, since I can't test it. Apart from superficial mistakes, this also requires dealing with Apple's texture format fuckups: they force you to use GL_LUMINANCE[_ALPHA] instead of GL_RED and GL_RG.

vd_lavc: prefer nvdec over vdpau with --hwdec=auto 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).

video: refactor how VO exports hwdec device handles The main change is with video/hwdec.h. mp_hwdec_info is made opaque (and renamed to mp_hwdec_devices). Its accessors are mainly thread-safe (or documented where not), which makes the whole thing saner and cleaner. In particular, thread-safety rules become less subtle and more obvious. The new internal API makes it easier to support multiple OpenGL interop backends. (Although this is not done yet, and it's not clear whether it ever will.) This also removes all the API-specific fields from mp_hwdec_ctx and replaces them with a "ctx" field. For d3d in particular, we drop the mp_d3d_ctx struct completely, and pass the interfaces directly. Remove the emulation checks from vaapi.c and vdpau.c; they are pointless, and the checks that matter are done on the VO layer. The d3d hardware decoders might slightly change behavior: dxva2-copy will not use the VO device anymore if the VO supports proper interop. This pretty much assumes that any in such cases the VO will not use any form of exclusive mode, which makes using the VO device in copy mode unnecessary. This is a big refactor. Some things may be untested and could be broken.

client API: expose OpenGL renderer This adds API to libmpv that lets host applications use the mpv opengl renderer. This is a more flexible (and possibly more portable) option to foreign window embedding (via --wid). This assumes that methods like context sharing and multithreaded OpenGL rendering are infeasible, and that a way is needed to integrate it with an application that uses a single thread to render everything. Add an example that does this with QtQuick/qml. The example is relatively lazy, but still shows how relatively simple the integration is. The FBO indirection could probably be avoided, but would require more work (and would probably lead to worse QtQuick integration, because it would have to ignore transformations like rotation). Because this makes mpv directly use the host application's OpenGL context, there is no platform specific code involved in mpv, except for hw decoding interop. main.qml is derived from some Qt example. The following things are still missing: - a way to do better video timing - expose GL renderer options, allow changing them at runtime - support for color equalizer controls - support for screenshots

vo_opengl, vo_opengl_cb: better hwdec interop backend selection Introduce the --opengl-hwdec-interop option, which replaces --hwdec-preload. The new option allows explicit selection of the interop backend. This is relatively complex, and I would have preferred not to add this, but it's probably useful to debug certain problems. In exchange, the "new" option documents that pretty much any but the simplest use of it will not be forward compatible.
