libvo: add vo_gl3 This new vo is heavily based on vo_gl.c. It provides better scale filters, dithering, and optional color management with LittleCMS2. It requires OpenGL 3. Many features are enabled by default, so it will be slower than vo_gl. However, it can be tuned to behave almost as vo_gl.

Move compat/ and bstr/ directory contents somewhere else bstr.c doesn't really deserve its own directory, and compat had just a few files, most of which may as well be in osdep. There isn't really any justification for these extra directories, so get rid of them. The compat/libav.h was empty - just delete it. We changed our approach to API compatibility, and will likely not need it anymore.

vo_opengl: always preload hwdec interop Simplifies some auto detection matters. I _still_ don't want to remove the lazy loading mechanism, because it's still slightly useful for filters using the hwdec APIs. My main motivation for not always preloading them is actually that libva prints random useless crap to the terminal with no way to prevent this.

#include "common/global.h"
Move options/config related files from mpvcore/ to options/ Since m_option.h and options.h are extremely often included, a lot of files have to be changed. Moving path.c/h to options/ is a bit questionable, but since this is mainly about access to config files (which are also handled in options/), it's probably ok.

Rename directories, move files (step 2 of 2) Finish renaming directories and moving files. Adjust all include statements to make the previous commit compile. The two commits are separate, because git is bad at tracking renames and content changes at the same time. Also take this as an opportunity to remove the separation between "common" and "mplayer" sources in the Makefile. ("common" used to be shared between mplayer and mencoder.)

video: move struct mp_hwdec_info into its own header file This means most code accessing this struct must now include hwdec.h instead of dec_video.h.

vo_opengl: add vsync-fences option Yet another relatively useless option that tries to make OpenGL's sync behavior somewhat sane. The results are not too encouraging. With a value of 1, vsync jitter is gone on nVidia, but there are frame drops (less than with glfinish). With 2, I get the usual vsync jitter _and_ frame drops. There's still some hope that it might prevent too deep queuing with some GPUs, I guess. The timeout for the wait call is 1 second. The value is pretty arbitrary; it should just not be too high to freeze the process (if the GPU is un-nice), and not too low to trigger the timeout in normal cases, even if the GPU load is very high. So I guess 1 second is ok as a timeout. The idea to use fences this way to control the queue depth was stolen from RetroArch: https://github.com/libretro/RetroArch/blob/df01279cf318e7ec90ace039d60515296e3de908/gfx/drivers/gl.c#L1856

vo_opengl: deprecate sub-options, add them as global options vo_opengl sub-option were always rather annoying to handle. It seems better to make them global options instead. This is simpler and easier to use. The only disadvantage we are aware of is that it's not clear that many/all of these new global options work with vo_opengl only. --vo=opengl-hq is also deprecated. There is extensive compatibility with the old behavior. One exception is that --vo-defaults will not apply to opengl-hq (though with opengl it still works). vo-cmdline is also dysfunctional and will be removed in a following commit. These changes also affect opengl-cb. The update mechanism is still rather inefficient: it requires syncing with the VO after each option change, rather than batching updates. There's also no granularity (video.c just updates "everything", and if auto-ICC profiles are enabled, vo_opengl.c will fetch them on each update). Most of the manpage changes were done by Niklas Haas <git@haasn.xyz>.

vo_opengl: minor changes to ICC update code Merge update_icc_profile() into get_and_update_icc_profile() - there's no reason anymore to keep them separate. The former is only called by the latter, and the separation of responsibilities between them is blurry a best. Query the ICC profile only if the corresponding feature is actually enabled. Additionally, change the error behavior of this code. Make loading failure non-fatal, and distinguish between runtime error and unimplemented functionality. Fix a memory leak in gl_lcms.c (although the changes in vo_opengl.c already take care of this, it's just logical and cleaner).

vo_opengl: add infrastructure for hardware decoding OpenGL interop Most hardware decoding APIs provide some OpenGL interop. This allows using vo_opengl, without having to read the video data back from GPU. This requires adding a backend for each hardware decoding API. (Each backend is an entry in gl_hwdec_vaglx[].) The backends expose video data as a set of OpenGL textures. Add infrastructure to support this. The next commit will add support for VA-API.

vo_opengl: add dxinterop backend WGL_NV_DX_interop is widely supported by Nvidia and AMD drivers. It allows a texture to be shared between Direct3D and WGL, so that rendering can be done with WGL and presentation can be done with Direct3D. This should allow us to work around some persistent WGL issues, such as dropped frames with some driver/OS combos, drivers that buffer frames to increase performance at the cost of latency, and the inability to disable exclusive fullscreen mode when using WGL to render to a fullscreen window. The addition of a DX_interop backend might also enable some cool Direct3D-specific enhancements in the future, such as using the GetPresentStatistics API to get accurate frame presentation timestamps. Note that due to a driver bug, this backend is currently broken on Intel. It will appear to work as long as the window is not resized too often, but after a few changes of size it will be unable to share the newly created renderbuffer with GL.

vo_opengl: add vsync-fences option Yet another relatively useless option that tries to make OpenGL's sync behavior somewhat sane. The results are not too encouraging. With a value of 1, vsync jitter is gone on nVidia, but there are frame drops (less than with glfinish). With 2, I get the usual vsync jitter _and_ frame drops. There's still some hope that it might prevent too deep queuing with some GPUs, I guess. The timeout for the wait call is 1 second. The value is pretty arbitrary; it should just not be too high to freeze the process (if the GPU is un-nice), and not too low to trigger the timeout in normal cases, even if the GPU load is very high. So I guess 1 second is ok as a timeout. The idea to use fences this way to control the queue depth was stolen from RetroArch: https://github.com/libretro/RetroArch/blob/df01279cf318e7ec90ace039d60515296e3de908/gfx/drivers/gl.c#L1856

vo_opengl: read framebuffer depth from actual FBO used for rendering In some cases, such as when using the libmpv opengl-cb API, or with certain vo_opengl backends, the main framebuffer is never accessed. Instead, rendering is done to a FBO that acts as back buffer. This meant an incorrect/broken bit depth could be used for dithering. Change it to read the framebuffer depth lazily on the first render call. Also move the main FBO field out of the GL struct to MPGLContext, because the renderer's init function does not need to access it anymore.

vo_opengl: create new API for OpenGL VO backends An attempt to get rid of the weird mix of callbacks that take either struct vo or MPGLCopntext as parameter. This is not perfect, and the API will probably change a bit until all other code is ported to it. the main question is how to separate struct vo completely from the windowing code, which actually needs vo for very little. In the end, the legacy callbacks will be dropped.

vo_opengl: always check GL errors in first 5 frames Normally, we don't want to call glGetError() all the time, because this supposedly causes slowdowns. (I could not measure any on Linux with nVidia binary drivers; maybe it's due to the fact that we have only a few, expensive calls per frame.) However, having to ask users to add the "debug" suboption when trying to diagnose problems is very annoying. Since most errors happen during initialization only, enabling it for the first 5 frames only is an interesting compromise.

Other important filters like vf_vapoursynth do not support "proper" format negotation either. Part of this was already removed with the vf_scale cleanup from today.

video: add a new method to configure filters and VOs The filter chain and the video ouputs have config() functions. They are strictly limited to transfering the video size and format. Other parameters (like color levels) have to be transferred separately. Improve upon this by introducing a separate set of reconfig() functions, which use mp_image_params to carry format parameters. This struct contains all image format related parameters from config(), plus additional parameters such as colorspace. Change vf_rotate to use it, as well as vo_opengl. vf_rotate is just an example/test case, but vo_opengl will need it later. The intention is also to get rid of VOCTRL_SET_YUV_COLORSPACE.

The force-gl2 suboption, which was an unreliable hack to run vo_gl3 in an OpenGL 2.1 context, is removed. Significant changes are done to the extension loader to make it easier to identify optional OpenGL features. Context creation is a bit changed to simplify the code and to handle the fallback better if OpenGL 3 context creation fails, and creating an OpenGL legacy context is attempted. Based on the initial work by Rudolf Polzer <divverent@xonotic.org>, which included making the shader GLSL 1.20 compatible, and more.

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: add infrastructure for hardware decoding OpenGL interop Most hardware decoding APIs provide some OpenGL interop. This allows using vo_opengl, without having to read the video data back from GPU. This requires adding a backend for each hardware decoding API. (Each backend is an entry in gl_hwdec_vaglx[].) The backends expose video data as a set of OpenGL textures. Add infrastructure to support this. The next commit will add support for VA-API.

video: move display and timing to a separate thread The VO is run inside its own thread. It also does most of video timing. The playloop hands the image data and a realtime timestamp to the VO, and the VO does the rest. In particular, this allows the playloop to do other things, instead of blocking for video redraw. But if anything accesses the VO during video timing, it will block. This also fixes vo_sdl.c event handling; but that is only a side-effect, since reimplementing the broken way would require more effort. Also drop --softsleep. In theory, this option helps if the kernel's sleeping mechanism is too inaccurate for video timing. In practice, I haven't ever encountered a situation where it helps, and it just burns CPU cycles. On the other hand it's probably actively harmful, because it prevents the libavcodec decoder threads from doing real work. Side note: Originally, I intended that multiple frames can be queued to the VO. But this is not done, due to problems with OSD and other certain features. OSD in particular is simply designed in a way that it can be neither timed nor copied, so you do have to render it into the video frame before you can draw the next frame. (Subtitles have no such restriction. sd_lavc was even updated to fix this.) It seems the right solution to queuing multiple VO frames is rendering on VO-backed framebuffers, like vo_vdpau.c does. This requires VO driver support, and is out of scope of this commit. As consequence, the VO has a queue size of 1. The existing video queue is just needed to compute frame duration, and will be moved out in the next commit.

This is simpler and easier to use. The only disadvantage we are aware of is that it's not clear that many/all of these new global options work with vo_opengl only. --vo=opengl-hq is also deprecated. There is extensive compatibility with the old behavior. One exception is that --vo-defaults will not apply to opengl-hq (though with opengl it still works). vo-cmdline is also dysfunctional and will be removed in a following commit. These changes also affect opengl-cb. The update mechanism is still rather inefficient: it requires syncing with the VO after each option change, rather than batching updates. There's also no granularity (video.c just updates "everything", and if auto-ICC profiles are enabled, vo_opengl.c will fetch them on each update). Most of the manpage changes were done by Niklas Haas <git@haasn.xyz>.

vo_opengl: add smoothmotion frame blending SmoothMotion is a way to time and blend frames made popular by MadVR. It's intended behaviour is to remove stuttering caused by mismatches between the display refresh rate and the video fps, while preserving the video's original artistic qualities (no soap opera effect). It's supposed to make 24fps video playback on 60hz monitors as close as possible to a 24hz monitor. Instead of drawing a frame once once it's pts has passed the vsync time, we redraw at the display refresh rate, and if we detect the vsync is between two frames we interpolated them (depending on their position relative to the vsync). We actually interpolate as few frames as possible to avoid a blur effect as much as possible. For example, if we were to play back a 1fps video on a 60hz monitor, we would blend at most on 1 vsync for each frame (while the other 59 vsyncs would be rendered as is). Frame interpolation is always done before scaling and in linear light when possible (an ICC profile is used, or :srgb is used).

vo: fix subtleties in the redrawing logic This fixes a race condition created by the previous commit, and possibly others. Sometimes interpolated frames weren't redrawn as uninterpolated ones. The problem is that redrawing/drawing a frame can't reset the VO want_redraw flags, because logically these have to happen after the core acknowledged and explicitly reissued a redraw. The core needs to be involved because the OSD text and drawings could depend on the playback or window state. Change it such that it always goes through the core. Also, VOs inconsistently called vo_wakeup() when setting want_redraw, which is also taken care of by this commit.

According to this data, the assumed ambient illuminance is 64 lux. This is the illuminance where the gamma that results from ICC color management is correct. On the other hand, BT.1886 formalizes that the gamma level for dim environments to be 2.40, and Apple resources (WWDC12: 2012 Session 523: Best practices for color management) define the BT.1886 dim at 16 lux. So the logic we apply is: * >= 64lux -> 1.961 gamma * =< 16lux -> 2.400 gamma * 16lux < x < 64lux -> logaritmic rescale of lux to gamma.

vo_opengl_cb: don't render OSD while VO is not created Unlike other VOs, this rendered OSD even while no VO was created (because the renderer lives as long as the API user wants). Change this, and refactor the code so that the OSD object is accessible only while the VO is created. (There is a short time where the OSD can still be accessed even after VO destruction - this is not a race condition, though it's inelegant and unfortunately unavoidable.)

vo_opengl: refactor queue configuration Just avoid some code duplication. Also, gl_video_set_options() having a queue size output parameter is weird at best. While I don't appreciate that this commit suddenly requires gl_video.c to deal with vo.c directly in a special case, it's simply the best place to put this function.

vo_opengl: add support for in memory icc profiles Previously we just forced loading a profile from file, but that has poor integration for querying the OS / display server for an ICC profile, and generating profiles on the fly (which we might use in the future for creating preset 3dluts). Also changed the previous icc-profile-auto code to use this mechanism, and moved gl_lcms to be an opaque type with state instead of just providing pure functions.

vo_opengl: possibly update icc profile after changing options Changing the options can enable icc-profile-auto, and in this case the profile has to be reteieved again from the system.

libvo: add vo_gl3 This new vo is heavily based on vo_gl.c. It provides better scale filters, dithering, and optional color management with LittleCMS2. It requires OpenGL 3. Many features are enabled by default, so it will be slower than vo_gl. However, it can be tuned to behave almost as vo_gl.

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, 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_cb, vo_opengl: add option for preloading hwdec context See manpage additions. This is mainly useful for vo_opengl_cb, but can also be applied to vo_opengl. On a side note, gl_hwdec_load_api() should stop using a name string, and instead always use the IDs. This should be cleaned up another time.

vo_opengl: deprecate sub-options, add them as global options vo_opengl sub-option were always rather annoying to handle. It seems better to make them global options instead. This is simpler and easier to use. The only disadvantage we are aware of is that it's not clear that many/all of these new global options work with vo_opengl only. --vo=opengl-hq is also deprecated. There is extensive compatibility with the old behavior. One exception is that --vo-defaults will not apply to opengl-hq (though with opengl it still works). vo-cmdline is also dysfunctional and will be removed in a following commit. These changes also affect opengl-cb. The update mechanism is still rather inefficient: it requires syncing with the VO after each option change, rather than batching updates. There's also no granularity (video.c just updates "everything", and if auto-ICC profiles are enabled, vo_opengl.c will fetch them on each update). Most of the manpage changes were done by Niklas Haas <git@haasn.xyz>.

video: add a new method to configure filters and VOs The filter chain and the video ouputs have config() functions. They are strictly limited to transfering the video size and format. Other parameters (like color levels) have to be transferred separately. Improve upon this by introducing a separate set of reconfig() functions, which use mp_image_params to carry format parameters. This struct contains all image format related parameters from config(), plus additional parameters such as colorspace. Change vf_rotate to use it, as well as vo_opengl. vf_rotate is just an example/test case, but vo_opengl will need it later. The intention is also to get rid of VOCTRL_SET_YUV_COLORSPACE. This information is now handed to the VOs via reconfig(). The getter, VOCTRL_GET_YUV_COLORSPACE, will still be needed though.

vo: change internal API for drawing frames draw_image_timed is renamed to draw_frame. struct frame_timing is renamed to vo_frame. flip_page_timed is merged into draw_frame (the additional parameters are part of struct vo_frame). draw_frame also deprecates VOCTRL_REDRAW_FRAME, and replaces it with a method that works for both VOs which can cache the current frame, and VOs which need to redraw it anyway. This is preparation to making the interpolation and (work in progress) display sync code saner. Lots of other refactoring, and also some simplifications.
