* video: redo video equalizer option handlingwm42017-08-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | 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.
* options: add a thread-safe way to notify option updateswm42017-08-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far, we had a thread-safe way to read options, but no option update notification mechanism. Everything was funneled though the main thread's central mp_option_change_callback() function. For example, if the panscan options were changed, the function called vo_control() with VOCTRL_SET_PANSCAN to manually notify the VO thread of updates. This worked, but's pretty inconvenient. Most of these problems come from the fact that MPlayer was written as a single-threaded program. This commit works towards a more flexible mechanism. It adds an update callback to m_config_cache (the thing that is already used for thread-safe access of global options). This alone would still be rather inconvenient, at least in context of VOs. Add another mechanism on top of it that uses mp_dispatch_queue, and takes care of some annoying synchronization issues. We extend mp_dispatch_queue itself to make this easier and slightly more efficient. As a first application, use this to reimplement certain VO scaling and renderer options. The update_opts() function translates these to the "old" VOCTRLs, though. An annoyingly subtle issue is that m_config_cache's destructor now releases pending notifications, and must be released before the associated dispatch queue. Otherwise, it could happen that option updates during e.g. VO destruction queue or run stale entries, which is not expected. Rather untested. The singly-linked list code in dispatch.c is probably buggy, and I bet some aspects about synchronization are not entirely sane.
* vo_opengl: add direct rendering supportwm42017-07-241-0/+32
| | | | | | | | | | | | | | | | | | | | Can be enabled via --vd-lavc-dr=yes. See manpage additions for what it does. This reminds of the MPlayer -dr flag, but the implementation is completely different. It's the same basic concept: letting the decoder render into a GPU buffer to avoid a copy. Unlike MPlayer, this doesn't try to go through filters (libavfilter doesn't support this anyway). Unless a filter can work in-place, DR will be silently disabled. MPlayer had very complex semantics about buffer types and management (which apparently nobody ever understood) and weird restrictions that mostly limited it to mpeg2 style codecs. The mpv code does not do any of this, and just lets the decoder allocate an arbitrary number of untyped images. (No MPlayer code was used.) Parts of the code based on work by atomnuker (starting point for the generic code) and haasn (some GL definitions, some basic PBO code, and correct fencing).
* vo_opengl: refactor vo performance subsystemNiklas Haas2017-07-011-3/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces `vo-performance` by `vo-passes`, bringing with it a number of changes and improvements: 1. mpv users can now introspect the vo_opengl passes, which is something that has been requested multiple times. 2. performance data is now measured per-pass, which helps both development and debugging. 3. since adding more passes is cheap, we can now report information for more passes (e.g. the blit pass, and the osd pass). Note: we also switch to nanosecond scale, to be able to measure these passes better. 4. `--user-shaders` authors can now describe their own passes, helping users both identify which user shaders are active at any given time as well as helping shader authors identify performance issues. 5. the timing data per pass is now exported as a full list of samples, so projects like Argon-/mpv-stats can immediately read out all of the samples and render a graph without having to manually poll this option constantly. Due to gl_timer's design being complicated (directly reading performance data would block, so we delay the actual read-back until the next _start command), it's vital not to conflate different passes that might be doing different things from one frame to another. To accomplish this, the actual timers are stored as part of the gl_shader_cache's sc_entry, which makes them unique for that exact shader. Starting and stopping the time measurement is easy to unify with the gl_sc architecture, because the existing API already relies on a "generate, render, reset" flow, so we can just put timer_start and timer_stop in sc_generate and sc_reset, respectively. The ugliest thing about this code is that due to the need to keep pass information relatively stable in between frames, we need to distinguish between "new" and "redrawn" frames, which bloats the code somewhat and also feels hacky and vo_opengl-specific. (But then again, this entire thing is vo_opengl-specific)
* vo.c, vo.h, vo_null.c: change license to LGPLwm42017-05-101-10/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most contributors have agreed. vo.c requires a "driver" entry for each video output - we assume that if someone who didn't agree to LGPL added a line, it's fine for vo.c to be LGPL anyway. If the affected video output is not disabled at compilation time, the resulting binary will be GPL anyway. One problem are the changes by Nick Kurshev (usually using "nick" as SVN username). He could not be reached. I believe all changes to his files are actually gone, but here is a detailed listing: fa1d5742bc: nick introduces a new VO API. It was removed in 64bedd9683. Some of this was replaced by VOCTRLs are introduced in 7c51652a1b, obviously replacing at least some functionality by his API. b587a3d642: nick adds a vo_tune_info_t struct. Removed in 64bedd9683 too. 9caad2c29a: nick adds some VOCTRLs, which were silently removed in 8cc5ba5ab8 (they became unused probably with the VIDIX removal). 340183b0e9: nick adds VO-based screenshots, which got removed in 2f4b840f62. Strangely the same name was introduced in 01cf896a2f again, but this is a coincidence and worked differently (also it was removed yet again in 2858232220). 104c125e6d: nick adds an option for "direct rendering". It was renamed in 6403904ae9 and fully removed in e48b21dd87. 5ddd8e92a1: nick adds code to check the VO driver preinit arg to every single VO driver. The argument itself and any possibly remaining code associated with it was removed in 1f5ffe7d30. f6878753fb: nick adds header inclusion guards. We assume this is not relevant for copyright. Some of nick's code was merely moved to other files, such as the equalizer stuff added in 555c676683 and moved in 4db72f6a80 and 12579136ff, and don't affect copyright of these files anymore. Other notes: fef7b17c34: a patch by someone who wasn't asked for relicensing added a symbol that was removed again in 1b09f4633. 4a8a46fafd: author probably didn't agree to LGPL, but the function signature was changed later on anyway, and nothing of this is left. 7b25afd742: the same author adds a symbol to what is vo.h today, which this relicensing commit removes, as it was unused. (It's not clear whether the mere symbol is copyrightable, but no need to take a risk.) 3a406e94d7, 9dd8f241ac: slave mode things by someone who couldn't be reached. This aspect of the old slave mode was completely removed. bbeb54d80a: patch by someone who was not asked, but the added code was completely removed again.
* options: remove deprecated sub-option handling for --vo and --aowm42016-11-251-9/+7
| | | | | | | | 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: make frame reupload logic more robustwm42016-11-011-0/+1
| | | | | | | | | | It's not that easy to decide whether a frame needs to be reuploaded/rerendered. Using unique frame IDs for input makes it slightly easier and more robust. This also removes the use of video PTS in the interpolation path. This should also avoid reuploading the video frame if it's just redrawn in paused mode, or when using OSD/subtitles in cover art mode.
* vo_opengl_cb: don't wait for redrawn frameswm42016-10-051-2/+4
| | | | | | | 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.
* x11: fix external fullscreen updatewm42016-09-231-1/+6
| | | | | | | | | | | | On x11, you can change the fullscreen via the window manager and without mpv's involvement. In these cases, the internal fullscreen flag has to be updated. The hack used for this didn't really work properly. Change it accordingly. The important thing is that the shadow copy of the option is updated. This is still not really ideal. Fixes #3570.
* vo: add a unique frame_id to vo_framewm42016-09-221-0/+6
| | | | | We think that this allows simpler logic than using the redraw and repeat fields. Not used yet.
* player, ao, vo: don't call mp_input_wakeup() directlywm42016-09-161-0/+2
| | | | | | | | | | | | | Currently, calling mp_input_wakeup() will wake up the core thread (also called the playloop). This seems odd, but currently the core indeed calls mp_input_wait() when it has nothing more to do. It's done this way because MPlayer used input_ctx as central "mainloop". This is probably going to change. Remove direct calls to this function, and replace it with mp_wakeup_core() calls. ao and vo are changed to use opaque callbacks and not use input_ctx for this purpose. Other code already uses opaque callbacks, or has legitimate reasons to use input_ctx directly (such as sending actual user input).
* vo: change defines to an enumwm42016-09-121-15/+17
| | | | | (They're flags, so it still doesn't make sense to actually name the enum and use it as a type.)
* vo: remove unused VOCTRL_GET_PANSCANwm42016-09-081-1/+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.
* options: add automagic hack for handling sub-option deprecationswm42016-09-051-0/+6
| | | | | | | | | | | | | | | | | I decided that it's too much work to convert all the VO/AOs to the new option system manually at once. So here's a shitty hack instead, which achieves almost the same thing. (The only user-visible difference is that e.g. --vo=name:help will list the sub-options normally, instead of showing them as deprecation placeholders. Also, the sub-option parser will verify each option normally, instead of deferring to the global option parser.) Another advantage is that once we drop the deprecated options, converting the remaining things will be easier, because we obviously don't need to add the compatibility hacks. Using this mechanism is separate in the next commit to keep the diff noise down.
* options: add a mechanism to make sub-option replacement slightly easierwm42016-09-051-0/+4
| | | | | | | | Instead of requiring each VO or AO to manually add members to MPOpts and the global option table, make it possible to register them automatically via vo_driver/ao_driver.global_opts members. This avoids modifying options.c/options.h every time, including having to duplicate the exact ifdeffery used to enable a driver.
* command: remove vo-cmdlinewm42016-09-021-1/+0
| | | | | | With the recent vo_opengl changes it doesn't do anything anymore. I don't think a deprecation period is necessary, because the command was always marked as experimental.
* vo_opengl: deprecate sub-options, add them as global optionswm42016-09-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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: use new option update mechanismwm42016-09-021-2/+4
| | | | | | | | | | | | | | | | This is still rather basic. run_reconfig() and run_control() update the options because it's needed for panscan (and other video scaling options), and fullscreen, border, ontop updates. In the old model, these options could be accessed only while both playback thread and VO threads were locked (i.e. during synchronous calls like vo_control()), so this should be sufficient in order not to miss any updates. In the future, a more fine-grained update mechanism could be added to handle these updates "exactly". x11_common.c contains an evil hack, as I see no reasonable way to handle this properly. The VO thread can't "lock" the main thread, so this is not simple.
* player: update Windows playback state asynchronouslywm42016-08-201-0/+1
| | | | | | | | | | | | | | | | | | Doing this required synchronizing with the VO thread, which could lead to audio dropouts if the VO was frozen (which can happen in practice if e.g. an opengl_cb user is not doing what the API demands). Add a way to send asynchronous VOCTRLs, and use that for the playback state. In theory, it would be better to make this status update a several function and to "merge" several queued update, but that would be slightly more effort/code, and the update is so infrequent that the merging would never happen anyway. The change to vo_destroy() is to make sure all queued asynchronous reuqests are finished before making the vo_thread exit. Even though it's only used on MS Windows, it's run on any platform with any VO, which makes this worse.
* vo: fix mismatching types in pointer operationwm42016-08-201-1/+1
| | | | | | | run_control() dereferences an uint32_t as int. Whether this is allowed depends on what uint32_t is typedefed to (dereferencing an unsigned int as int should be fine). Fix it by always using int. The uint32_t type never really made sense.
* player: fix display-sync timing if audio take long on resumewm42016-08-071-0/+1
| | | | | | | | | | | | | | | | | In display-sync mode, the very first video frame is idiotically fully timed, even though audio has not been synced yet at this point, and the video frame is more like a "preview" frame. But since it's fully timed, an underflow is detected if audio takes longer than the display time of the frame (we send the second frame only after audio is done). The timing code will try to compensate for the determined desync, but it really shouldn't. So explicitly discard the timing info in this specific case. On the other hand, if the first frame still hasn't finished display, we can pretend everything is ok. This is a hack - ideally, we either would send a frame without timing info (and then send it again or so when playback starts properly), or we would add real pause support to the VO, and pause it during syncing.
* vo: remove now unused event_fd handlingwm42016-07-211-4/+2
|
* vo_opengl: allow backends to provide callbacks for custom event loopswm42016-07-201-1/+2
| | | | | | | Until now, this has been either handled over vo.event_fd (which should go away), or by putting event handling on a separate thread. The backends which do the latter do it for a reason and won't need this, but X11 and Wayland will, in order to get rid of event_fd.
* vo_opengl: expose performance timers as propertiesNiklas Haas2016-06-071-0/+12
| | | | | | | | | | | This is plumbed through a new VOCTRL, VOCTRL_PERFORMANCE_DATA, and exposed as properties render-time-last, render-time-avg etc. All of these numbers are in microseconds, which gives a good precision range when just outputting them via show-text. (Lua scripts can obviously still do their own formatting etc.) Signed-off-by: wm4 <wm4@nowhere>
* vo_opengl: apply vo-cmdline command incrementallywm42016-06-051-0/+1
| | | | | | | | | | Instead of implicitly resetting the options to defaults and then applying the options, they're always applied on top of the current options (in the same way adding new options to the CLI command line will). This does not apply to vo_opengl_cb, because that has an even worse mess which I refuse to deal with.
* video: refactor how VO exports hwdec device handleswm42016-05-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* win32: make taskbar progress indication optionalmaniak13492016-05-081-0/+1
| | | | | | | | | | | Add --taskbar-progress command line option and property which controls taskbar progress indication rendering in Windows 7+. This option is on by default and can be toggled during playback. This option does not affect the creation process of ITaskbarList3. When the option is turned off the progress bar is just hidden with TBPF_NOPROGRESS. Closes #2535
* vo: get rid of vo_get_window_title()wm42015-12-061-2/+0
| | | | | | | | | | | It always was a weird artifact - VOCTRLs are meant _not_ to require special handling in the code that passes them through (like in vo.c). Removing it is also interesting to further reduce the dependency of backends on struct vo. Just get rid of it. Removing it is somewhat inconvenient, because in many situations the UI window is created after the first VOCTRL_UPDATE_WINDOW_TITLE. This means these backends have to store it in a new field in their own context.
* vo_opengl: fix interpolation with display-syncwm42015-11-281-0/+3
| | | | | | | | | | | | | | | | | | | | At least I hope so. Deriving the duration from the pts was not really correct. It doesn't include speed adjustments, and becomes completely wrong of the user e.g. changes the playback speed by a huge amount. Pass through the accurate duration value by adding a new vo_frame field. The value for vsync_offset was not correct either. We don't need the error for the next frame, but the error for the current one. This wasn't noticed because it makes no difference in symmetric cases, like 24 fps on 60 Hz. I'm still not entirely confident in the correctness of this, but it sure is an improvement. Also, remove the MP_STATS() calls - they're not really useful to debug anything anymore.
* vo: change vo_frame field unitswm42015-11-271-2/+2
| | | | | | | This was just converting back and forth between int64_t/microseconds and double/seconds. Remove this stupidity. The pts/duration fields are still in microseconds, but they have no meaning in the display-sync case (also drop printing the pts field from opengl/video.c - it's always 0).
* vo_opengl: disable interpolation without display-syncwm42015-11-251-2/+1
| | | | | Without display-sync mode, our guesses wrt. vsync phase etc. are much worse, and I see no reason to keep the complicated "vsync_timed" code.
* command, vo: add estimated-display-fps propertywm42015-11-251-0/+2
| | | | | | | | | | This is simply the average refresh rate. Including "bad" samples is actually an advantage, because the property exists only for informational purposes, and will reflect problems such as the driver skipping a vsync. Also export the standard deviation of the vsync frame duration (normalized to the range 0-1) as vsync-jitter property.
* vo: remove VOCTRL_GET_RECENT_FLIP_TIMEwm42015-11-231-1/+0
| | | | | | | | | | | It doesn't have any real purpose anymore. Up until now, it was still implemented by vo_wayland, but since we changed how the frame callbacks work, even that appears to be pointless. Originally, the plan was to somehow extend this mechanism to all backends and to magically fix frame scheduling, but since we can't hope for proper mechanisms even on wayland, this idea looks way less interesting.
* win32: don't show progress indicator in idle modeJames Ross-Gowan2015-11-231-0/+1
|
* win32: support taskbar button progress indicatorMartin Herkt2015-11-151-0/+7
| | | | | | | | | | | This adds support for the progress indicator taskbar extension that was introduced with Windows 7 and Windows Server 2008 R2. I don’t like this solution because it keeps its own state and introduces another VOCTRL, but I couldn’t come up with anything less messy. closes #2399
* player: account for minor VO underrunswm42015-11-141-1/+1
| | | | | | | | | If the player sends a frame with duration==0 to the VO, it can trivially underrun. Don't panic, but keep the correct time. Also, returning the absolute time from vo_get_next_frame_start_time() just to turn it into a float with relative time was silly. Rename it and make it return what the caller needs.
* command: rename vo-missed-frame-count propertywm42015-11-131-1/+1
| | | | | | | | | "Missed" implies the frame was dropped, but what really happens is that the following frame will be shown later than intended (due to the current frame skipping a vsync). (As of this commit, this property is still inactive and always returns 0. See git blame for details.)
* vo_opengl, vo_opengl_cb: drop unneeded vo_frame fieldswm42015-11-041-3/+2
| | | | | | | | | 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.)
* video/out: remove an unused parameterwm42015-10-031-10/+2
| | | | | | | | | | | 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: change some defines to enumswm42015-10-021-9/+13

| | | | | | | You needed to select a GL backend with the backend suboption. This was confusing. Fixes #2361.
* player: add display sync modewm42015-08-101-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | If this mode is enabled, the player tries to strictly synchronize video to display refresh. It will adjust playback spe
