* wayland: refactor surface scalingDudemanguy2021-06-302-33/+56
| | | | | | | | | | | | | | | Another day, another wayland refactor. Way back when, dcc3c2e added support for the hidpi-window-scale option (something you probably should never set to no but whatever) to wayland. Well technically, it never had any runtime toggling support (don't remember if detecting when vo_opts changed was possible or not then; maybe not). Anyways in the process of fixing that, I went ahead and refactored how this is all handled. The key difference is that when hidpi-window-scale is disabled, wl->scaling is directly set to 1 instead of forcibly setting wl->current_output->scale to 1. Note that scaling operations don't always require a geometry reset/resize so set_surface_scaling needs to be separate from set_geometry. The logic here is kind of complicated but it (should) be correct.
* wayland: fix wl_surface_set_buffer_scale usageDudemanguy2021-06-273-3/+2
| | | | | | | | | | | The wl_surface lives for the entire lifetime of the vo. It's only neccesary to set the scale initially and when the output scaling changes (the surface moves to a different output with a different scale or the output itself changes it scale). All of the calls that were being made in the egl/vulkan resize functions are not needed. vo_wlshm wasn't correctly rescaling itself before this commit since it had no logic to handle scale changes. This should all be shared, common code in the surface/output listeners.
* wayland: always be sure to initially try to renderDudemanguy2021-06-275-8/+7
| | | | | | | | | | | | | | | | | | | A subtle regression from c26d833. On sway if mpv was set to be a floating window in the config, set_buffer_scale would actually get applied twice according to the wayland log. That meant a 1920x1080 window would appear as a 960x540 window if the scale of the wl_output was set to 2. This only affected egl on sway (didn't occur on weston and was too lazy to try anything else; probably they were fine). Since wl->render is initially false, that meant that the very first run through the render loop returns false. This probably caused something weird to happen with the set_buffer_scale calls (the egl window gets created and everything but mpv doesn't write to it just yet) which makes the set_buffer_scale call happen an extra time. Since it was always intended for mpv to initally render, this is worth fixing. Just chnage wl->render to wl->hidden (again) and flip the bools around. That way, the initial false value results in render == true and mpv tries to draw on the first pass. This fixes the weird scaling behavior because reasons.
* wayland: remove unused includesDudemanguy2021-06-272-6/+0
| | | | Presentation time only lives in in wayland_common.
* wayland: handle app id option less stupidlyDudemanguy2021-06-261-4/+0
| | | | | | Not sure what I was on when I wrote this. wayland-app-id is supposed to default to "mpv". Just set that in the vo_sub_opts and don't do this weird m_config_cache_write_opt thing. Also make the doc entry nicer.
* wayland: reorganize wayland common codeDudemanguy2021-06-265-948/+962
| | | | | | | Mostly a cosmetic change that (hopefully) makes things look better. Some functions and structs that were previously being exported in the wayland header were made static to the wayland_common.c file (these shouldn't be accessed by anyone else).
* vo_gpu: vulkan: displayvk: Fix handling of unconnected planesPhilip Langdale2021-06-121-1/+6
| | | | | | | | If a plane is not connected to any displays, we won't set an entry in the mapping of planes to displays. So ensure these unset entries are null and skip them. Fixes #8913
* vo_gpu: vulkan: implement a VkDisplayKHR backed contextPhilip Langdale2021-06-112-0/+392
| | | | | | | | | | | | | | | | | | | | | | | | This is the Vulkan equivalent of the drm context for OpenGL, with the big difference that it's implemented purely in terms of Vulkan calls and doesn't actually require drm or kms. The basic idea is to identify a display, mode, and plane on a device, and then create a display backed surface for the swapchain. In theory, past that point, everything is the same, and this is in fact the case on Intel hardware. I can get a video playing on a vt. On nvidia, naturally, things don't work that way. Instead, nvidia only implemented the extension for scenarios where a VR application is stealing a display from a running window system, and not for standalone scenarios. With additional code, I've got this scenario to work but that's a separate incremental change. Other people have tested on AMD, and report roughly the same behaviour as on Intel. Note, that in this change, the VT will not be correctly restored after qutting. The only way to restore the VT is to introduce some drm specific code which I will illustrate in a separate change.
* vo_gpu: vulkan: provide a helper to access device name optionPhilip Langdale2021-06-112-0/+17
| | | | | | | | | | | The VkDisplayKHR context type requires making calls against the physical device before the libplacebo context is initialised. That means we can't simply use the physical device object that libplacebo would create - instead we have to create a separate one, but make sure it's referring to the same physical device. To that end, we need the device name that the user may have requested so we can pass it on.
* vo_rpi: fix argument nameDudemanguy2021-06-081-2/+2
| | | | This is data not arg.
* wayland: refactor dispatching eventsDudemanguy2021-05-281-46/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was originally just a bugfix for a race condition, but the scope expanded a bit. Currently, the wayland code does a prepare_read -> dispatch_pending -> display_flush -> read_events -> dispatch_pending routine that's basically straight from the wayland client API documentation. This essentially just queues up all the wayland events mpv has and dispatches them to the compositor. We do this for blocking purposes on every frame we render. A very similar thing is done for wait_events from the VO. This code can pretty easily be unified and split off into a separate function, vo_wayland_dispatch_events. vo_wayland_wait_frame will call this function in a while loop (which will break either on timeout or if we receive frame callback from the compositor). wait_events needs to just check this in case we get some state change on the wakeup_pipe (i.e. waking up from the paused state). As for the actual bugfix part of this, it's a slight regression from c26d833. The toplevel config event always forced a redraw when a surface became activated again. This is for something like displaying cover art on a music file. If the window was originally out of view and then later brought back into focus, no picture would be rendered (i.e. the window is just black). That's because something like cover art is just 1 frame and the VO stops doing any other additional rendering. If you miss that 1 frame, nothing would show up ever again. The fix in this case is to always just force a redraw when the mpv window comes back into view. Well with the aforementioned commit, we stopped doing wl_display_roundtrip calls on every frame. That means we no longer do roundtrip blocking calls. We just be sure to queue up all of the events we have and then dispatch them. Because wayland is fundamentally an asynchronous protocol, there's no guarantee what order these events would be processed in. This meant that on occasion, a vo_wayland_wait_frame call (this could occur multiple times depending on the exact situation) would occur before the compositor would send back frame callback. That would result in the aforementioned bug of having just a black window. The fix, in this case, is to just do a vo_wayland_wait_frame call directly before we force the VO to do a redraw. Note that merely dispatching events isn't enough because we specifically need to wait for the compositor to give us frame callback before doing a new render. P.S. fix a typo too.
* win32: support the property 'focused'Avi Halachmi (:avih)2021-05-271-1/+12
| | | | | | | | | | | | | And also change the existing WM_KILLFOCUS handler to return 0 instead of 'break' (which later calls DefWindowProcW), as MSDN says we should do for WM_{KILL,SET}FOCUS. It seems that the 'focused' property is now supported by all main VOs: x11, macOS, wayland, Windows. TCT/sixel/caca probably don't support it, and unknown with SDL. Fixes #8868
* vo_gpu: replace --icc-contrast by --icc-force-contrastNiklas Haas2021-05-261-41/+40
| | | | | | | | | | | | | | Not only does this have semantics that make far more sense, it also has a default that makes far more sense. (Equivalent to the old `icc-contrast=inf`) This removes the weird 1000:1 contrast default assumption which especially broke perceptual profiles and also screws things up for OLED/CRT/etc. Should probably close some issues but I honestly can't be bothered to figure out which of the thousands colorimetry-related issues are affected.
* wayland: shuffle around the render loop againDudemanguy2021-05-245-35/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Take two. f4e89dd went wrong by moving vo_wayland_wait_frame before start_frame was called. Whether or not this matters depends on the compositor, but some weird things can happen. Basically, it's a scheduling issue. vo_wayland_wait_frame queues all events and sends them to the server to process (with no blocking if presentation time is available). If mpv changes state while rendering (and this function is called before every frame is drawn), then that event also gets dispatched and sent to the compositor. This, in some cases, can cause some funny behavior because the next frame gets attached to the surface while the old buffer is getting released. It's safer to call this function after the swap already happens and well before mpv calls its next draw. There's no weird scheduling of events, and the compositor log is more normal. The second part of this is to fix some stuttering issues. This is mostly just conjecture, but probably what was happening was this thing called "composition". The easiest way to see this is to play a video on the default audio sync mode (probably easiest to see on a typical 23.976 video). Have that in a window and float it over firefox (floating windows are bloat on a tiling wm anyway). Then in firefox, do some short bursts of smooth scrolling (likely uses egl). Some stutter in video rendering could be observed, particularly in panning shots. Compositors are supposed to prevent tearing so what likely was happening was that the compositor was simply holding the buffer a wee bit longer to make sure it happened in sync with the smooth scrolling. Because the mpv code waits precisely on presentation time, the loop would timeout on occasion instead of receiving the frame callback. This would then lead to a skipped frame when rendering and thus causing stuttering. The fix is simple: just only count consecutive timeouts as not receiving frame callback. If a compositor holds the mpv buffer slightly longer to avoid tearing, then we will definitely receive frame callback on the next round of the render loop. This logic also appears to be sound for plasma (funfact: Plasma always returns frame callback even when the window is hidden. Not sure what's up with that, but luckily it doesn't matter to us.), so get rid of the goofy 1/vblank_time thing and just keep it a simple > 1 check.
* wayland: send VO_EVENT_DPI on output event as wellDudemanguy2021-05-231-0/+1
| | | | The display scaling might change here, so we need to signal mpv's core.
* vo_gpu: fix extreme clipping with --gamut-clipping for HDR outputsNiklas Haas2021-05-221-1/+2
| | | | | | Checking against 1.0 is wrong for this code, because it's in an absolute luminance scale relative to reference white. We should be normalizing this by `dst.sig_peak`.
* wayland: simplify render loopDudemanguy2021-05-225-49/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is actually a very nice simplification that should have been thought of years ago (sue me). In a nutshell, the story with the wayland code is that the frame callback and swap buffer behavior doesn't fit very well with mpv's rendering loop. It's been refactored/changed quite a few times over the years and works well enough but things could be better. The current iteration works with an external swapchain to check if we have frame callback before deciding whether or not to render. This logic was implemented in both egl and vulkan. This does have its warts however. There's some hidden state detection logic which works but is kind of ugly. Since wayland doesn't allow clients to know if they are actually visible (questionable but whatever), you can just reasonably assume that if a bunch of callbacks are missed in a row, you're probably not visible. That's fine, but it is indeed less than ideal since the threshold is basically entirely arbitrary and mpv does do a few wasteful renders before it decides that the window is actually hidden. The biggest urk in the vo_wayland_wait_frame is the use of wl_display_roundtrip. Wayland developers would probably be offended by the way mpv abuses that function, but essentially it was a way to have semi-blocking behavior needed for display-resample to work. Since the swap interval must be 0 on wayland (otherwise it will block the entire player's rendering loop), we need some other way to wait on vsync. The idea here was to dispatch and poll a bunch of wayland events, wait (with a timeout) until we get frame callback, and then wait for the compositor to process it. That pretty much perfectly waits on vsync and lets us keep all the good timings and all that jazz that we want for mpv. The problem is that wl_display_roundtrip is conceptually a bad function. It can internally call wl_display_dispatch which in certain instances, empty event queue, will block forever. Now strictly speaking, this probably will never, ever happen (once I was able to to trigger it by hardcoding an error into a compositor), but ideally vo_wayland_wait_frame should never infinitely block and stall the player. Unfortunately, removing that function always lead to problems with timings and unsteady vsync intervals so it survived many refactors. Until now, of course. In wayland, the ideal is to never do wasteful rendering (i.e. don't render if the window isn't visible). Instead of wrestling around with hidden states and possible missed vblanks, let's rearrange the wayland rendering logic so we only ever draw a frame when the frame callback is returned to use (within a reasonable timeout to avoid blocking forever). This slight rearrangement of the wait allows for several simplifications to be made. Namely, wl_display_roundtrip stops being needed. Instead, we can rely entirely on totally nonblocking calls (dispatch_pending, flush, and so on). We still need to poll the fd here to actually get the frame callback event from the compositor, but there's no longer any reason to do extra waiting. As soon as we get the callback, we immediately draw. This works quite well and has stable vsync (display-resample and audio). Additionally, all of the logic about hidden states is no longer needed. If vo_wayland_wait_frame times out, it's okay to assume immediately that the window is not visible and skip rendering. Unfortunately, there's one limitation on this new approach. It will only work correctly if the compositor implements presentation time. That means a reduced version of the old way still has to be carried around in vo_wayland_wait_frame. So if the compositor has no presentation time, then we are forced to use wl_display_roundtrip and juggle some funny assumptions about whether or not the window is hidden or not. Plasma is the only real notable compositor without presentation time at this stage so perhaps this "legacy" mechanism could be removed in the future.

* Revert "vo_gpu: revert 8a09299 and conditionally clear framebuffer again"Your Name2021-05-071-5/+3
| | | | | | | | | | This reverts commit b8156a9a86ae4ff087b1b255c68a3ca38ec2d086. Apparently there are two problems here. One on Linux (fixed by the original change and this revert) and one on alternative-medicine-Job's OS. Since the latter has deprecated OpenGL and OpenGL is a second-class citizen, I think it's better to prefer the fix for a platform that is still alive.
* vf_sub: restore OSD if removedYour Name2021-05-071-0/+9
| | | | | | | When inserting vf_sub, the VO OSD is directed not to draw itself. But this flag was never unset, even when removing vf_sub. The fix is pretty shit, but appears to work.

* command: add display-width/display-height propertyDudemanguy2021-05-067-0/+34
| | | | | | | | | For some reason, this never existed before. Add VOCTRL_GET_DISPLAY_RES and use it to obtain the current display's resolution from each vo/windowing backend if applicable. Users can then access the current display resolution as display-width and display-height as per the client api. Note that macOS/cocoa was not attempted in this commit since the author has no clue how to write swift.
* filter_kernels: fix quadric windowNiklas Haas2021-05-041-1/+1
| | | | | | | | | 3909e4cdfcb9 seems to have replaced this 0.5 constant by 0.75, using its presence in glumpy as justification. 0.75 is clearly a bug in glumpy, as its own source code doesn't even match the comment immediately above it. Every other implementation of this window I could find uses 0.5, including e.g. ImageMagick.

* wayland: ignore toplevel listener if geometry is 0Dudemanguy2021-04-261-0/+4
| | | | | | | | | | It turns out that if a user specifies fullscreen=yes and a width/height in an autoprofile, the compositor can execute its toplevel listener event. This can happen before we have any mpv window rendered at all so we end up performing a bunch of geometry operations and state checks when we shouldn't. It subtly messes up a lot of things like state detection. Just return from this function if the geometry has no width or height yet.
* mac: fix window geometry calculation on secondary screensder richter2021-04-241-19/+26
| | | | | | | | | | | | | | | this is a regression of af26402, where we changed the geometry calculation to use the visible frame and consider its origin. though the origin is not screen relative but relative to the main screen. the rest of the code expects a screen relative rectangle. because of that windows would be placed out of the screen bounds when not on the main screen. recalculate to origin to be screen relative and use those values for the rest of the calculations. to make the code a bit more comprehensible be a bit more explicit about what is done where with temporary variables and comments. also move the mp_rect calculation that moves the origin and flips the y position to a separate function, so we can reuse it later.
* win32: fit_window_on_screen: simplify, add commentsAvi Halachmi (:avih)2021-04-231-16/+17
| | | | | | | | | | The fit_on_screen logic was a bit twisted. Simplify it a bit and update few comments to explain better what it's used for. Note that the new logic is not identical to before, but its intent should now be clearer. This means there might be regressions or improvements at edge cases. If followup fixes are needed, then we should keep the intent clear. Most likely though that it's fine.
* win32: fit_window_on_screen: centralize logic (no-op)Avi Halachmi (:avih)2021-04-231-4/+3
| | | | | | | | fit_on_screen is called only from reinit_window_state. Move the yes/no logic unmodified from fit_on_screen to reinit_window_state, and remove the w32->parent condition because it's already checked earlier at reinit_window_state.
* win32: fit_window_on_screen: ensure top edge is insideAvi Halachmi (:avih)2021-04-231-6/+18
| | | | | | | | | | | | | | | | | | | | | Previously, because the video (client area) was centered but the top and bottom borders are uneven (title is taller), then if the window is shrunk vertically to just-fit the desktop - the top edge of the title bar ended above the top edge of the display. This is a state which Windows prevents during manual move, but apparently it's not rejected at the Windows API. Now we ensure it doesn't happen, and nudge the window down to align the top edges if necessary. This is a commulative regression of commits 981048e0 and 364af7c6. To clarify functionality, this includes a no-op change: fit_rect was renamed to fit_rect_size and it now takes explicit width and height, because it only used the width/height of rc2 anyway. Fixes #6695
* options: win32: ignore and deprecate --fit-borderAvi Halachmi (:avih)2021-04-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The accurate description of this option was: - fit-border is enabled by default. When disabled, it adds a bug where if the window has borders and mpv shrinks it to fit the desktop, then the calculation ignores the borders and adds incorrect video crop. The option was added at commits 70f64f3c and 949247d6, in order to solve an issue (#2935) where if mpv wanted to display a video with size WxH, then w32_common.c incorrectly set the window to WxH, while down-scaling the video slightly to fit (even with small sizes). It was addressed with a new option which is enabled by default, but does the right thing (sets the client area to WxH) only when disabled, so that everyone who prefers their video slightly downscaled could keep their default behavior. (#2935 also addressed an off-by-one issue, fixed before fit-border) While disabling the option did avoid unnecessary downscaling, it also added a bug when disabled: the borders are no longer taken into account when the size is too big for the desktop. Most users don't notice and are unaffected as it's enabled by default. Shortly later (981048e0) the core issue is fixed, and now the client area is correctly set to WxH instead of the window (and together with the three following commits which center the video, adds a new bug where the window title can be outside the display - addressed next). However, fit-border remained, now without any effect, except that it still has the same bug when disabled and the window is too big. Later code changes and refactoring preserved this issue with great attention to details, and it remained in identical form until now. Simply rip out fit-border.
* vo_gpu: greatly increase maximum shader cache sizeNiklas Haas2021-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | See #8137 for justification. This is not ideal, because a large cache results in a lot of `strcmp` invocations for every single shader invocation. But it's way better than resulting in a lot of shader recompilations for every single shader invocation. The only reason I don't want to uncap it altogether is because there are conceivable edge cases in which users load dynamically generated shaders with updated parameters (indeed, I've seen IRC discussions to this effect), and in this case, we don't want to grow the cache infinitely as a result of something like a floating point parameter being continuously updated. (Never mind that this *would* actually trigger worst case behavior for the `strcmp`, since the updated float constant is likely to be near the bottom of the shader body) Whatever. vo_placebo will liberate us all in the end.
* wayland: workaround hidden state detection badnessDudemanguy2021-04-182-2/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The wayland code uses a heuristic to determine whether or not the mpv window is hidden since the xdg-shell protocol does not provide a way for a client to directly know this. We don't render with the frame callback function for various, complicated reasons but the tl;dr is that it doesn't work well with mpv's core (maybe an essay should be written on this one day). Currently, the aforementioned heuristic considers a window hidden if we miss more frames in a row than the display's current refresh rate (completely arbitrary number). However, the wayland protocol does allow for the display's refresh rate to be 0 in certain cases (like a virtual output). This completely wrecks the heuristic and basically causes only every other frame to be rendered (real world example: nested sway sessions). Instead let's slightly redesign this mechanism to be a little smarter. For coming up with the vblank time (to predict when to timeout on the wait function), instead use the vsync interval calculated using presentation time. That is the most accurate measure available. If that number is not available/invalid, then we try to use the vsync interval predicted by the presentation event. If we still don't have that (i.e. no presentation time supported by the compositor), we can instead use the old way of using the expected vsync interval from the display's reported refresh rate. If somehow we still do not have a usable number, then just give up and makeup shit. Note that at this point we could technically ask the vo for the estimated vsync jitter, but that would involve locking/unlocking vo which sounds horrifying. Ideally, you never reach here. See https://github.com/swaywm/wlroots/issues/2566 for the actual target of this fix. wlroots uses presentation time so in practice we are mostly just using that calculated vsync interval number.
* wayland: update geometry + cursor on output eventDudemanguy2021-04-161-40/+56
| | | | | | | | | | | | | | | | | | | | The wayland output listener can update whenever something about the output changes (resolution, scale). Currently, the mpv VO updates correctly when the refresh rate changes, but changes of both scale and resolution were not considered. This causes a bug in certain cases like the mouse surface not being shown at certain scale factors due to the cursor scale not being updated correctly. Also autofit type options would not update if the resolution changes. To fix this, we must always reset the window geometry and wl scaling whenever the output event occurs on wl->current_output. There is no way to know precisely what changed from the previous state, so all of the parameters must be reset and then resized. As an aside, this apparently doesn't fix all cursor problem as there's apparently a bug in libwayland-cursor(*). It's still something we should be doing regardless. *: https://gitlab.freedesktop.org/wayland/wayland/-/issues/194
* wayland: support the display-hidpi-scale propertyDudemanguy2021-04-121-0/+8
| | | | | | | | | | | | | | So apparently this property had existed since 2019. Internally, it's used as a part of the console.lua script for scaling. Yours truly somehow didn't bat an eye at the fact that the text in the console was super small (made worse by the fact that xwayland does scale) and just ignored it for all this time. Oh well. To report dpi changes to mpv's core, we need to use VO_EVENT_DPI in a couple of places. One place is, of course, the surface listener if the scale value reported by the wayland server changes. The other place is in the very first reconfig since mpv's core will not find the correct scale value until we actually get a wl_output from the wayland server.
* vo_gpu: adjust interpolation_threshold's defaultLaserEyess2021-03-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When mpv attempts to play a video that is, on average, 60 FPS on a display that is not exactly 60.00 Hz, two options try to fight each other: `video-sync-max-video-change` and `interpolation-threshold`. Normally, container FPS in something such as an .mp4 or a .mkv is precise enough such that the video can be retimed exactly to the display Hz and inte
