vo_opengl: D3D11VA + ANGLE interop This uses ID3D11VideoProcessor to convert the video to a RGBA surface, which is then bound to ANGLE. Currently ANGLE does not provide any way to bind nv12 surfaces directly, so this will have to do. ID3D11VideoContext1 would give us slightly more control about the colorspace conversion, though it's still not good, and not available in MinGW headers yet. The video processor is created lazily, because we need to have the coded frame size, of which AVFrame and mp_image have no concept of. Doing the creation lazily is less of a pain than somehow hacking the coded frame size into mp_image. I'm not really sure how ID3D11VideoProcessorInputView is supposed to work. We recreate it on every frame, which is simple and hopefully doesn't affect performance.

d3d11va: store texture/subindex in IMGFMT_D3D11VA plane pointers Basically this gets rid of the need for the accessors in d3d11va.h, and the code can be cleaned up a little bit. Note that libavcodec only defines a ID3D11VideoDecoderOutputView pointer in the last plane pointers, but it tolerates/passes through the other plane pointers we set.

vo_opengl: angle: dynamically load ANGLE 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.

#include "video/out/gpu/hwdec.h"
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_opengl: d3d11egl: native NV12 sampling support This uses EGL_ANGLE_stream_producer_d3d_texture_nv12 and related extensions to map the D3D textures coming from the hardware decoder directly in GL. In theory this would be trivial to achieve, but unfortunately ANGLE does not have a mechanism to "import" D3D textures as GL textures. Instead, an awkward mechanism via EGL_KHR_stream was implemented, which involves at least 5 extensions and a lot of glue code. (Even worse than VAAPI EGL interop, and very far from the simplicity you get on OSX.) The ANGLE mechanism so far supports only the NV12 texture format, which means 10 bit won't work. It also does not work in ES3 mode yet. For these reasons, the "old" ID3D11VideoProcessor code is kept and used as a fallback.

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.

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_opengl: angle: dynamically load ANGLE 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: EGL: fix hwdec probing If ANGLE was probed before (but rejected), the ANGLE API can remain "initialized", and eglGetCurrentDisplay() will return a non-NULL EGLDisplay. Then if a native GL context is used, the ANGLE/EGL API will then (apparently) keep working alongside native OpenGL API. Since GL objects are just numbers, they'll simply fail to interact, and OpenGL will get invalid textures. For some reason this will result in black textures. With VAAPI-EGL, something similar could happen in theory, but didn't in practice.

video: remove d3d11 video processor use from OpenGL interop We now have a video filter that uses the d3d11 video processor, so it makes no sense to have one in the VO interop code. The VO uses it for formats not directly supported by ANGLE (so the video data is converted to a RGB texture, which ANGLE can take in). Change this so that the video filter is automatically inserted if needed. Move the code that maps RGB surfaces to its own inteorp backend. Add a bunch of new image formats, which are used to enforce the new constraints, and to automatically insert the filter only when needed. The added vf mechanism to auto-insert the d3d11vpp filter is very dumb and primitive, and will work only for this specific purpose. The format negotiation mechanism in the filter chain is generally not very pretty, and mostly broken as well. (libavfilter has a different mechanism, and these mechanisms don't match well, so vf_lavfi uses some sort of hack. It only works because hwaccel and non-hwaccel formats are strictly separated.) The RGB interop is now only used with older ANGLE versions. The only reason I'm keeping it is because it's relatively isolated (uses only existing mechanisms and adds no new concepts), and because I want to be able to compare the behavior of the old code with the new one for testing. It will be removed eventually. If ANGLE has NV12 interop, P010 is now handled by converting to NV12 with the video processor, instead of converting it to RGB and using the old mechanism to import that as a texture.

Where they fail is texture creation, where we try to create D3D11_BIND_DECODER surfaces. So specifically try to detect this situation. One issue is that once the hwdec interop is created, the damage is done, and it can't use another backend (because currently only 1 hwdec backend is supported). So that's where we prevent attempts to use it. It still can fail when trying to use d3d11va-copy (since that doesn't require an interop backend), but at that point we don't care anymore - dxva2(-copy) is tried before that anyway.

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.

vo_opengl: D3D11VA + ANGLE interop This uses ID3D11VideoProcessor to convert the video to a RGBA surface, which is then bound to ANGLE. Currently ANGLE does not provide any way to bind nv12 surfaces directly, so this will have to do. ID3D11VideoContext1 would give us slightly more control about the colorspace conversion, though it's still not good, and not available in MinGW headers yet. The video processor is created lazily, because we need to have the coded frame size, of which AVFrame and mp_image have no concept of. Doing the creation lazily is less of a pain than somehow hacking the coded frame size into mp_image. I'm not really sure how ID3D11VideoProcessorInputView is supposed to work. We recreate it on every frame, which is simple and hopefully doesn't affect performance.

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.

video: remove d3d11 video processor use from OpenGL interop We now have a video filter that uses the d3d11 video processor, so it makes no sense to have one in the VO interop code. The VO uses it for formats not directly supported by ANGLE (so the video data is converted to a RGB texture, which ANGLE can take in). Change this so that the video filter is automatically inserted if needed. Move the code that maps RGB surfaces to its own inteorp backend. Add a bunch of new image formats, which are used to enforce the new constraints, and to automatically insert the filter only when needed. The added vf mechanism to auto-insert the d3d11vpp filter is very dumb and primitive, and will work only for this specific purpose. The format negotiation mechanism in the filter chain is generally not very pretty, and mostly broken as well. (libavfilter has a different mechanism, and these mechanisms don't match well, so vf_lavfi uses some sort of hack. It only works because hwaccel and non-hwaccel formats are strictly separated.) The RGB interop is now only used with older ANGLE versions. The only reason I'm keeping it is because it's relatively isolated (uses only existing mechanisms and adds no new concepts), and because I want to be able to compare the behavior of the old code with the new one for testing. It will be removed eventually. If ANGLE has NV12 interop, P010 is now handled by converting to NV12 with the video processor, instead of converting it to RGB and using the old mechanism to import that as a texture.

video: remove d3d11 video processor use from OpenGL interop We now have a video filter that uses the d3d11 video processor, so it makes no sense to have one in the VO interop code. The VO uses it for formats not directly supported by ANGLE (so the video data is converted to a RGB texture, which ANGLE can take in). Change this so that the video filter is automatically inserted if needed. Move the code that maps RGB surfaces to its own inteorp backend. Add a bunch of new image formats, which are used to enforce the new constraints, and to automatically insert the filter only when needed. The added vf mechanism to auto-insert the d3d11vpp filter is very dumb and primitive, and will work only for this specific purpose. The format negotiation mechanism in the filter chain is generally not very pretty, and mostly broken as well. (libavfilter has a different mechanism, and these mechanisms don't match well, so vf_lavfi uses some sort of hack. It only works because hwaccel and non-hwaccel formats are strictly separated.) The RGB interop is now only used with older ANGLE versions. The only reason I'm keeping it is because it's relatively isolated (uses only existing mechanisms and adds no new concepts), and because I want to be able to compare the behavior of the old code with the new one for testing. It will be removed eventually. If ANGLE has NV12 interop, P010 is now handled by converting to NV12 with the video processor, instead of converting it to RGB and using the old mechanism to import that as a texture.

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_opengl: D3D11VA + ANGLE interop This uses ID3D11VideoProcessor to convert the video to a RGBA surface, which is then bound to ANGLE. Currently ANGLE does not provide any way to bind nv12 surfaces directly, so this will have to do. ID3D11VideoContext1 would give us slightly more control about the colorspace conversion, though it's still not good, and not available in MinGW headers yet. The video processor is created lazily, because we need to have the coded frame size, of which AVFrame and mp_image have no concept of. Doing the creation lazily is less of a pain than somehow hacking the coded frame size into mp_image. I'm not really sure how ID3D11VideoProcessorInputView is supposed to work. We recreate it on every frame, which is simple and hopefully doesn't affect performance.
