* video: redo video equalizer option handlingwm42017-08-221-34/+3
| | | | | | | | | | | | | | | | | | | | | | | I really wouldn't care much about this, but some parts of the core code are under HAVE_GPL, so there's some need to get rid of it. Simply turn the video equalizer from its current fine-grained handling with vf/vo fallbacks into global options. This makes updating them much simpler. This removes any possibility of applying video equalizers in filters, which affects vf_scale, and the previously removed vf_eq. Not a big loss, since the preferred VOs have this builtin. Remove video equalizer handling from vo_direct3d, vo_sdl, vo_vaapi, and vo_xv. I'm not going to waste my time on these legacy VOs. vo.eq_opts_cache exists _only_ to send a VOCTRL_SET_EQUALIZER, which exists _only_ to trigger a redraw. This seems silly, but for now I feel like this is less of a pain. The rest of the equalizer using code is self-updating. See commit 96b906a51d5 for how some video equalizer code was GPL only. Some command line option names and ranges can probably be traced back to a GPL only committer, but we don't consider these copyrightable.
* vo_opengl: separate hwdec context and mapping, port it to use rawm42017-08-101-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: further GL API use separationwm42017-08-071-5/+22
| | | | | | | | | | | | | | | Move multiple GL-specific things from the renderer to other places like vo_opengl.c, vo_opengl_cb.c, and ra_gl.c. The vp_w/vp_h parameters to gl_video_resize() make no sense anymore, and are implicitly part of struct fbodst. Checking the main framebuffer depth is moved to vo_opengl.c. For vo_opengl_cb.c it always assumes 8. The API user now has to override this manually. The previous heuristic didn't make much sense anyway. The only remaining dependency on GL is the hwdec stuff, which is harder to change.
* vo_opengl: move GL state resetting to vo_opengl_cbwm42017-08-051-3/+13
| | | | | | | | | This code is pretty much for the sake of vo_opengl_cb API users. It resets certain state that either the user or our code doesn't reset correctly. This is somewhat outdated. With GL implicit state being so awfully large, it seems more reasonable require that any code restores the default state when returning to the caller. Some exceptions are defined in opengl_cb.h.
* vo: fix subtleties in the redrawing logicwm42017-02-211-1/+0
| | | | | | | | | | | | | | | | | 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.
* vo_opengl, vo_opengl_cb: better hwdec interop backend selectionwm42017-01-171-8/+2
| | | | | | | | | | | 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: cleanup messy option synchronizationwm42017-01-171-24/+16
| | | | | | | | Replace the old code, that played games to evade thread-safety issues, with newer thread-safe option access functions. This also means mp_opengl_create() doesn't need to cache the hwdec settings anymore. (They're applied in mpv_opengl_cb_init_gl() instead.)
* client API: allow passing NULL to mpv_opengl_cb_uninit_gl()wm42016-12-091-0/+3
| | | | In which case it does nothing.
* options: remove deprecated sub-option handling for --vo and --aowm42016-11-251-9/+1
| | | | | | | | Long planned. Leads to some sanity. There still are some rather gross things. Especially g_groups is ugly, and a hack that can hopefully be removed. (There is a plan for it, but whether it's implemented depends on how much energy is left.)
* vo_opengl_cb: fix a race conditionwm42016-10-301-2/+4
| | | | | | | | | | When pthread_cond_timedwait(), the condition we are checking for could be true or false. This code assumed it was always false. This should be an extremely obscure race condition, since it can happen only if timeout and the condition changing sort of happen at the same time, or the lock is held for a longer time (which it normally isn't). But I could observe it a few times.
* vo_opengl_cb: fix inverted conditionwm42016-10-301-1/+1
| | | | Commit e6291697 got this wrong.
* vo_opengl_cb: update current frame if a frame is droppedwm42016-10-301-1/+2
| | | | | | | Even if a frame is dropped due to the libmpv API user not drawing a frame, it should be set as current frame. This avoids dropping a frame forever in certain circumstances such as cover art of the API user was stuck at initialization or such.
* vo_opengl_cb: don't wait for redrawn frameswm42016-10-051-1/+2
| | | | | | | This also removes some extra waiting if no video is active, at least in theory. Also clarify the vo_frame flag comments for redraw/repeat.
* vo: remove unused VOCTRL_GET_PANSCANwm42016-09-081-2/+0
| | | | | | It was used to determine whether the VO supports VOCTRL_SET_PANSCAN. With all those changes to property semantics this became unnecessary, and its only use was dropped at some point.
* vo_opengl: deprecate sub-options, add them as global optionswm42016-09-021-62/+16
| | | | | | | | | | | | | | | | | | | | | | | | 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>.
* options: make mp_vo_opts options an actual sub-option groupwm42016-08-301-1/+1
| | | | | | | | | | | Just a minor refactor along the planned option change. This commit will make it easier to update (i.e. copy) the VO options without copying _all_ options. For now, behavior should be equivalent, though. (The VO options were put into a separate struct quite early - when all global variables were removed from the source code. It wasn't clear whether the separate struct would have any actual purpose, but it seems it will now. Awesome, huh.)
* vo_opengl_cb: log better error message if OpenGL not initialized by userwm42016-08-031-0/+6
| | | | | Otherwise opengl/video.c would confusingly complain about a wrong version, which in this case makes no sense.
* vo_opengl_cb: icc-profile-auto does not and will not workwm42016-06-051-0/+2
| | | | | In theory we could probably make icc-profile-auto a vo_opengl-specific option, but I won't bother with this. Logging an error is simpler.
* vo_opengl: move all icc handling from vo_opengl.c to video.cwm42016-06-031-1/+1
| | | | | | | | | | | | | | | Originally, video.c did not access any CMS things (other than lut3d being set on it), but this has changed. In practice, almost all accesses to it have moved to video.c. vo_opengl only created it, and set the auto icc profile path. Complete the move. Some things wrt. option handling are a bit fishy. (But when is this not the case.) icc-profile-auto was not tested, but the distributed human CI will take care of it.
* video: refactor how VO exports hwdec device handleswm42016-05-091-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | 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: generate 3DLUT against source and use full BT.1886Niklas Haas2016-04-011-1/+1
| | | | | | | | | | | | | | | | | | | This commit refactors the 3DLUT loading mechanism to build the 3DLUT against the original source characteristics of the file. This allows us, among other things, to use a real BT.1886 profile for the source. This also allows us to actually use perceptual mappings. Finally, this reduces errors on standard gamut displays (where the previous 3DLUT target of BT.2020 was unreasonably wide). This also improves the overall accuracy of the 3DLUT due to eliminating rounding errors where possible, and allows for more accurate use of LUT-based ICC profiles. The current code is somewhat more ugly than necessary, because the idea was to implement this commit in a working state first, and then maybe refactor the profile loading mechanism in a later commit. Fixes #2815.
* vo_opengl_cb: unbreak destroying+recreating GL contextwm42016-02-151-2/+2
| | | | | | A client API user is allowed to call mpv_opengl_cb_uninit_gl() followed by mpv_opengl_cb_init_gl(). This crashed; fix it by fixing the lifetime of ctx->gl.
* vo_opengl_cb: do also not block when drawing nothingwm42016-02-091-1/+1
| | | | | | | The ctx->redrawing field signals whether flip_page() should block. Do not block if a black frame (i.e. nothing) is to be rendered. Also, frame==NULL can never happen.
* mpv_talloc.h: rename from talloc.hDmitrij D. Czarkoff2016-01-111-1/+1
| | | | This change helps avoiding conflict with talloc.h from libtalloc.
* vo_opengl_cb: avoid NULL pointer deref in corner caseswm42015-12-051-1/+2
| | | | Found by Coverity.
* vo_opengl_cb: pass mpv_global to gl_videowm42015-11-301-1/+1
| | | | | | | | I guess gl_video->global was originally meant to be optional, but now it crashes in some newer code with vo_opengl_cb, which tries to init it with this field set to NULL (because normally it's not needed). Probably fixes #2542.
* videotoolbox: make decoder format customizablewm42015-11-171-1/+4
| | | | | | | | | | Because apparently there's no ideal universally working format. The weird OpenGL texture format for kCVPixelFormatType_32BGRA is from: http://stackoverflow.com/questions/22077544/draw-an-iosurface-to-an-opengl-context (Which apparently got it from the linked Apple example code.)
* vo_opengl_cb: do not block on flipping when redrawingwm42015-11-121-0/+5
| | | | | Gives slightly better behavior when used with Qt. (Which tends not to flip buffers when the window is not visible.)
* vo_opengl_cb: better underflow reportingwm42015-11-101-6/+12
| | | | | | | This applies to unexpected freezes or deadlocks, not e.g. normal framedrops. The verbose messages also might remind an API user if the API usage is incorrect, such as not calling mpv_opengl_cb_draw() when a redraw request was issued.
* vo_opengl_cb: make operation more similar to normal VOswm42015-11-091-118/+54
| | | | | | | | | | | | | | | | | | | | | vo_opengl_cb is a special case, because we somehow have to render video asynchronously, all while "trusting" the API user to do it correctly. This didn't quite work, and a while ago a compromise using a timeout to prevent theoretically possible deadlocks was added. Make it even more synchronous. Basically, go all the way, and synchronize rendering between VO and user renderer thread to the full extent possible. This means the silly frame queue is dropped, and we event attempt to synchronize the GL SwapBuffer call (via mpv_opengl_cb_report_flip()). The changes introduced with commit dc33eb56 are effectively dropped. I don't even remember if they mattered. In the future, we might make all VOs fetch asynchronously from a frame queue, which would mostly remove the differences between vo_opengl and vo_opengl_cb, but this will take a while (if it will even be done).
* vo_opengl_cb: log some eventswm42015-11-041-0/+4
| | | | | | | | | | The noframe event is logged whenever there is no new frame. This can happen due to normal redraws, but also due to video frame queue underflow. The mpv_opengl_cb_report_flip() API function is currently pretty useless, because blocking on the video frame queue is more reliable and simpler. But at least we can log the actual vsync.
* vo_opengl, vo_opengl_cb: drop unneeded vo_frame fieldswm42015-11-041-20/+1
| | | | | | | | | next_vsync/prev_vsync was only used to retrieve the vsync duration. We can get this in a simpler way. This also removes the vsync duration estimation from vo_opengl_cb.c, which is probably worthless anyway. (And once interpolation is made display-sync only, this won't matter at all.)
* vo_opengl_cb: fix passing through some video equalizer propertieswm42015-10-231-2/+7
| | | | | | | | | | | | | | | | | | | | | | The equalizer code as it exists in vo_opengl works perfectly fine. The situation in vo_opengl_cb is pretty different. The playback thread can't communicate with the renderer thread synchronously (essentially to give the API user more flexibility). So the equalizer communication has to be done in an asynchronous way too. There were two problems. First, the eq capabilities can change with the pixel format, and the renderer initializes them on config only. This means equalizers were disabled on the first config run, and options like --video-output-levels or --brightness would not work. So we just initialize the caps with a known superset. The player will not correctly indicate when setting an eq doesn't work, but we're fine with it, as it is a relatively cosmetic issue. Second, it copied back the eq settings in the "wrong" moment (what for?), which overwrote the settings in some cases. Third, the eq was not reset correctly on vo init. This is needed to make it behave the same as vo_opengl.
* vo_opengl_cb: fix pausing and seeking if interpolation is enabledwm42015-10-141-1/+20
| | | | | | | | | | | | | | | When seeking, the current frame will have the wrong timestamp, until the seek is done and a new frame from the seek target is shown. We still use the "old" frame for redrawing during seeks. This frame has to be explicitly marked with still=true in order not to confuse the interpolation queue. If this is not done, it will ignore frames until a frame with approximately the same timestamp as the "old" frame is reached. (Does this mean interpolation handles timestamp resets incorrectly? I have no idea.) Of course we also have to clear possibly queued frames on seeks. Also, in pausing, explicitly let the frame redraw.
* video/out: remove an unused parameterwm42015-10-031-1/+1
| | | | | | | | | | | This parameter has been unused for years (the last flag was removed in commit d658b115). Get rid of it. This affects the general VO API, as well as the vo_opengl backend API, so it touches a lot of files. The VOFLAGs are still used to control OpenGL context creation, so move them to the OpenGL backend code.
* vo_opengl: remove gl_ prefixes from files in video/out/openglNiklas Haas2015-09-091-3/+3
| | | | | This is a bit redundant with the name of the directory itself, and not in line with existing naming conventions.
* vo_opengl: move gl_* files to their own subdirNiklas Haas2015-09-091-3/+3
| | | | | This is mainly just to keep things a bit more organized and separated inside the codebase.
* vo_opengl: refactor queue configurationwm42015-07-161-3/+2
| | | | | | | 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_cb, vo_opengl: add option for preloading hwdec contextwm42015-07-071-14/+6
| | | | | | | | 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_cb: drop frames eagerly if frames are not renderedwm42015-07-071-1/+7
| | | | | libmpv users might stop calling the frame render callback for stupid reasons, at which point video frames would pile up.
* vo_opengl_cb: fix interpolation code pathwm42015-07-011-6/+2
|
* vo: change internal API for drawing frameswm42015-07-011-57/+47
| | | | | | | | | | | | | | 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.
* vo_opengl: adjust interpolation code for the new video-sync mechanismNiklas Haas2015-07-011-1/+1
| | | | | | | | | | | | | This should make interpolation work much better in general, although there still might be some side effects for unusual framerates (eg. 35 Hz or 48 Hz). Most of the common framerates are tested and working fine. (24 Hz, 30 Hz, 60 Hz) The new code doesn't have support for oversample yet, so it's been removed (and will most likely be reimplemented in a cleaner way if there's enough demand). I would recommend using something like robidoux or mitchell instead of oversample, though - they're much smoother for the common cases.
* video: pass future frames to VOwm42015-07-011-1/+1
| | | | | | | | | | Now the VO can request a number of future frames with the last parameter of vo_set_queue_params(). This will be helpful to fix the interpolation code. Note that the first frame (after playback start or seeking) will usually not have any future frames (to make seeking fast). Near the end of the file, the number of future frames will become lower as well.
* vo_opengl: add support for custom shadersNiklas Haas2015-05-271-1/+1
|
* vo_opengl_cb: add support for interpolationwm42015-05-121-5/+51
| | | | | | | | | | | | | | | | | This uses the OpenGL frame interpolation code, which before could be used by vo_opengl only. Some effort was made to make it behave like vo_opengl, for the better or the worse. As a consequence, there is a minor duplication of code and mechanism. Hopefully this can all be wiped as soon as the VO frame queue/timing mechanism is cleaned up. This also attempts to use mpv_opengl_cb_report_flip() (as called by the API user) to determine the vsync interval. This might need refinement as well. (In general, we simply expect the API user to work in vsync-blocking manner.)
* vo_opengl_cb: add a "block" framedrop mode and make it defaultwm42015-05-121-5/+27
| | | | | | | | | (I have no idea why there are different modes.) Instead of risking to drop frames too early, give it some margin. Since there are situations this could deadlock, wait with a timeout. This can happen if e.g. the API user is refusing to render anything, or if uninitialization is happening.
* vo_opengl_cb: actually set requested optionswm42015-05-121-0/+1
| | | | Quite an oversight.
* vo_opengl: refactor wayland frame skippingwm42015-05-011-1/+1
| | | | | | | | | | | Currently, the wayland backend needs extra work to avoid drawing more often than the wayland frame callback allows. (This is not ideal, but will be fixed at a later time.) Unify this with the start_frame callback added for cocoa. Some details change for the better. For example, if a frame is dropped, and a redraw is done afterwards, the actually correct frame is redrawn, instead whatever was in the textures from before the dropped frame.
* vo_opengl_cb: deprecate mpv_opengl_cb_render()wm42015-04-091-2/+1
| | | | Its vp parameter made no sense anymore. Introduce a new one.
* vo_opengl_cb: add a function to report vsync timewm42015-04-091-0/
