* player: update duration based on highest timestamp demuxedwm42017-12-241-0/+1
| | | | | | | | This will help with things like livestreams. As a minor detail, subtitles are excluded, because they sometimes have "unused" events after video and audio ends. To avoid this annoying corner case, just ignore them.
* build: add preliminary LGPL modewm42017-09-211-2/+0
| | | | | | | See "Copyright" file for caveats. This changes the remaining "almost LGPL" files to LGPL, because we think that the conditions the author set for these was finally fulfilled.
* player: change license of most core files to LGPLwm42017-06-231-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These files have all in common that they were fully or mostly taken from mplayer.c. (mplayer.c was a huge file that contains almost all of the playback core, until it was split into multiple parts.) This was probably the hardest part to relicense, because so much code was moved around all the time. player/audio.c still does not compile. We'll have to redo audio filtering. Once that is done, we can probably actually provide an actual LGPL configure switch. Here is a relatively detailed list of potential issues: 8d190244: author did not reply, parts were made GPL-only in a previous commit. 7882ea9b: author could not be reached, but the code is gone. wscript still has --datadir switch, but I don't think this is relevant to copyright. f197efd5: unclear origin, but I consider the code gone anyway (replaced with generic OSD mechanisms). 8337d9c2: author did not reply, but only the option still exists (under a different name), other code was removed. d8fd7131: did not reply. Disabled in a previous commit. 05258251: same author as above. Both fields actually seem to have vanished (even when tracking renames), so no action taken. d459e644, 268b2c1a: author did not reply, but we reuse only the options (with different names and slightly or fully different semantics, and completely different implementations), so I don't think this is relevant for copyright. 09e742fe, 17c39c4e: same as above. e8a173de, bff4b3ee: author could not be reached. The commands were reworked to properties, and the code outside of the TV code were moved back to the TV code. So I don't think copyright applies to the current command.c parts (mp_property_tv_color, mp_property_tv_freq, mp_property_tv_scan). The TV parts remain GPL. 0810e427: could not be reached. Disabled in a previous commit. 43744a2d: unknown author, but this was replaced by dynamic alloc (if the change is even copyrightable). 116ca0c7: unknown author; reasoning see input.c relicensing commit. e7e4d1d8: these semantics still exist, but as generic code, and this code was fully removed. f1175cd9: the author of the cited patch is unknown, and upon inspection it turns out that I was only using the idea to pause the player on EOF, so I claim it's not copyright relevant. 25affdcc: author could not be reached (yet) - but it's only a function rename, not copyrightable. 5728504c was committed by Arpi (who agreed), but hints that it might be by a different author. In fact it seems to be mostly this patch: http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2001-November/002041.html The author did not respond, but it all seems to have been removed later. It's a terrible mess though. Arpi reverted the A-V sync code at first, but left the RTC code for a while. The following commits remove these changes 100%: 14b35442, 7181a091, 31482783, 614f8475, df58e822. cehoyos did explicitly not agree to LGPL, but was involved in the following changes: c99d8fc8: applied a patch and didn't modify it, the original author agreed. 40ac0d31: author could not be reached, but all code is gone anyway. The "af" command has a similar function, but works completely different and actually reuses a mechanism older than this patch. 54350436: applied a patch, but didn't modify it, except for adding a German translation, which was removed later. a2dda036: same situation as above 240b743e: this was made GPL-only in a previous commit 7b25afd7: same as above (for now) kirijua could not be reached, but was a regular patch contributor: c2c997fd: video equalizer code move; probably not copyrightable. Is GPL due to Nick anyway. be54f481: technically, this became the audio track property later. But all what is left is the fact that you pass a track ID to it, so consider the original coypright non-relevant. 2f376d1b: this was rewritten in b7052b43, but for now we can afford to be careful, so this was marked as GPL only in a previous commit. 43844d09: remaining parts in main.c were reverted in a previous commit. anders has mostly disagreed with the LGPL relicensing. Does not want libaf to become LGPL, but made some concessions. In particular, he granted us permission to relicense 4943e9c52c and 242aa6ebd4. We also consider some of his changes remaining in mpv not relevant for copyright (such as 735de602 - we won't remove the this option completely). We will completely remove his other contributions, including the entire audio filter chain. For now, this stuff is marked as GPL only. The remaining question is how much code in player/audio.c (based on the former mplayer.c and dec_audio.c) is under his copyright. I made claims about this in a previous commit. Nick(ols) Kurshev, svn username "nick" and "nickols_k", could not be reached. He had a lot of changes in early MPlayer. It seems all of that was removed, at least in mpv. His main work, like VIDIX or libswscale work, does not exist in mpv anymore, but the changes to mplayer.c and other core parts still deserve attention: a4119f6b, fb927549, ad3529b8, e11b23dc, 5f2178be, 93c371d5: removed in b43d67e0, d1628d12, 24ed01fe, df58e822. 0a83c6ec, 104c125e, 4e067f62, aec5dcc8, b587a3d6, f3de6e6b: DR, VAA, and "tune" stuff was fully removed later on or replaced with other mechanisms. 340183b0: screenshots were redone later (the VOCTRL was even removed, with an independent implementation using the same VOCTRL a few years later), so not relevant anymore. Basically only the 's' shortcut remains (but not its implementation). 92c5c274, bffd4007, 555c6766: for now marked as GPL only in a previous commit. Might contain some trace amounts of "michael"'s copyright, who agreed to LGPL only once the core is relicensed. This will still be respected, but I don't think it matters at this in this case. (Some code touched by him was merged into mplayer.c, and then disappeared after heavy refactoring.) I tried to be as careful and as complete as possible. It can't be excluded that amends to this will be made later. This does not make the player LGPL yet.
* player: fix core-idle and eof-reached update notifcationswm42017-04-141-0/+1
| | | | | | | | Make mpv_observe_property() work correctly on them even with --keep-open-pause=no. This also changes the situations in which the screensaver is enabled/disabled subtly.
* options: slightly better option update mechanismwm42016-09-191-0/+1
| | | | | | | | | | | | | | Extend the flag-based notification mechanism that was used via M_OPT_TERM. Make the vo_opengl update mechanism use this (which, btw., also fixes compilation with OpenGL renderers forcibly disabled). While this adds a 3rd mechanism and just seems to further the chaos, I'd rather have a very simple mechanism now, than actually furthering the mess by mixing old and new update mechanisms. In particular, we'll be able to remove quite some property implementations, and replace them with much simpler update handling. The new update mechanism can also more easily refactored once we have a final mechanism that handles everything in an uniform way.
* options: take care of propertly updating options on runtime changeswm42016-09-171-0/+3
| | | | | | | | | | | | | | | | | | | | | | All option write accesses are now put through the property interface, which means runtime option value verification and runtime updates are applied. This is done even for command line arguments and config files. This has many subtle and not-so-subtle consequences. The potential for unintended and intended subtle or not-subtle behavior changes is very large. Architecturally, this is us literally jumping through hoops. It really should work the other way around, with options being able to have callbacks for value verification and applying runtime updates. But this would require rewriting the entirety of command.c. This change is more practical, and if anything will at least allow incremental changes. Some options are too incompatible for this to work - these are excluded with an explicit blacklist. This change fixes many issues caused by the mismatch between properties and options. For example, this fixes #3281.
* command: add options to property listwm42016-09-011-2/+2
| | | | | | | | | | | Now options are accessible through the property list as well, which unifies them to a degree. Not all options support runtime changes (meaning affected components need to be restarted for the options to take effects). Remove from the manpage those properties which are cleanly mapped to options anyway. From the user-perspective they're just options available through the property interface.
* player: make looping slightly more seamlesswm42016-08-181-1/+1
| | | | | | This affects A-B loops and --loop-file, and audio. Instead of dropping audio by resetting the AO, try to make it seamless by not sending data after the loop point, and after the seek send new data without a reset.
* player: rewrite deinterlace filter auto-insertionwm42016-07-051-3/+0
| | | | | | | | | | | | | | Instead of using the "vf" command code (which changes filters at runtime on user input), use the general filter-insertion code. The latter was added later, and is more suitable for automatically inserted filters. The old code failed in particular when using watch-later saving, which stored the filter list in the resume config file. If a user changed the hardware decoding mode via command line, the stored filter chain was out of date and could cause failure due to not working with hardware or software decoding mode. Storing the deinterlace filter in the filter list was unavoidable, because it was part of the user state. (The new code only edits the actually instantiated filters.)
* command: improve playlist* properties change notificationswm42016-06-201-0/+1
| | | | | | | Until now, only the "playlist" property itself had proper change notification. Extend it to all other properties as well. Fixes #3267 (hopefully).
* video: always re-probe auto deint filter on filter reconfigwm42015-07-211-0/+5
| | | | | | | | | If filters are disabled or reconfigured, attempt to remove and probe the deinterlace filter again. This fixes behavior if e.g. a software deint filter was automatically inserted, and then hardware decoding is enabled during playback. Without this commit, initializing hw decoding would fail because of the software filter; with this commit, it'll replace it with the hw deinterlacer instead.
* command: do not exit playback if the B point of A-B loop is past EOFwm42015-06-161-0/+2
| | | | | | | | | | | | | | The previous behavior is confusing if the B point is near EOF (consider B being the duration of the file, which is strictly speaking past the last video timestamp). The new behavior is fine as well for B being far past EOF. Achieve this by checking the EOF state in addition to whether playback has reached the B point. Also, move the A-B loop code out of command_event(). It just isn't useful anymore, and obfuscates the code more than it makes it loop simple. Fixes #2046.
* command: remove unnecessary event IDswm42015-06-091-2/+0
| | | | | These were actually not needed for correct function, since individual property change notifications via mp_notify_property() are used.
* client API: add glue for making full use of mpv_command_node()wm42015-04-201-1/+2
| | | | | Until now, the return value was always MPV_FORMAT_NONE. Now a command can actually set it. This will be used in one of the following commits.
* Update license headersMarcin Kurczewski2015-04-131-5/+4
| | | | Signed-off-by: wm4 <wm4@nowhere>
* player: fix audio-device-list updateswm42015-02-141-0/+2
| | | | | | | The way the AO wakes up the playloop has nothing to do with events; instead we must query the events on the AO once the playloop was woken up. Querying the events in every playloop iteration is thus the correct way to do this.
* ao_coreaudio: add support for hotplug notificationsStefano Pigozzi2015-02-141-0/+1
| | | | | | | | | | This commit adds notifications for hot plugging of devices. It also extends the old behaviour of the `audio-out-detected-device` property which is now backed by the hotplugging code. This allows clients to be notified when the actual audio output device changes. Maybe hotplugging should be supported for ao_coreaudio_exclusive too, but it's device selection code is a bit fragile.
* audio: add device change notification for hotpluggingwm42015-02-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Not very important for the command line player; but GUI applications will want to know about this. This only adds the internal API; support for specific audio outputs comes later. This reuses the ao struct as context for the hotplug event listener, similar to how the "old" device listing API did. This is probably a bit unclean and confusing. One argument got reusing it is that otherwise rewriting parts of ao_pulse would be required (because the PulseAudio API requires so damn much boilerplate). Another is that --ao-defaults is applied to the hotplug dummy ao struct, which automatically applies such defaults even to the hotplug context. Notification works through the property observation mechanism in the client API. The notification chain is a bit complicated: the AO notifies the player, which in turn notifies the clients, which in turn will actually retrieve the device list. (It still has the advantage that it's slightly cleaner, since the AO stuff doesn't need to know about client API issues.) The weird handling of atomic flags in ao.c is because we still don't require real atomics from the compiler. Otherwise we'd just use atomic bitwise operations.
* command: send additional property change events in-between loadingwm42015-02-011-0/+1
| | | | | | | | Opening the stream and opening the demuxer are both done asynchronously, meaning the player reacts to client API requests. They also can potentially take a while. Thus it's better to process outstanding property changes, so that change events are sent for properties that were changed during opening.
* client API: notify API user on event queue overflowwm42015-01-191-1/+1
| | | | | | | | | | | | | | | Before this, we merely printed a message to the terminal. Now the API user can determine this properly. This might be important for API users which somehow maintain complex state, which all has to be invalidated if (state-changing) events are missing due to an overflow. This also forces the client API user to empty the event queue, which is good, because otherwise the event queue would reach the "filled up" state immediately again due to further asynchronous events being added to the queue. Also add some minor improvements to mpv_wait_event() documentation, and some other minor cosmetic changes.
* command: add window-minimized property (X11 only)wm42014-11-021-0/+1
| | | | | | More or less requested by #1237. Should be simple to extend this to other backends.
* command: make window-scale property observablewm42014-11-021-3/+7
| | | | | | | | | | | | Add a generic mechanism to the VO to relay "extra" events from VO to player. Use it to notify the core of window resizes, which in turn will be used to mark all affected properties ("window-scale" in this case) as changed. (I refrained from hacking this as internal command into input_ctx, or to poll the state change, etc. - but in the end, maybe it would be best to actually pass the client API context directly to the places where events can happen.)
* command: remove hook cancellation mechanismwm42014-10-201-1/+0
| | | | | I doubt anyone will actually use this correctly. Also, there was a bug (a typo) which prevented it from working at all.
* command: add a mechanism to allow scripts to intercept file loadswm42014-10-161-0/+4
| | | | | | | | | | | | | | | | | | | | | | | A vague idea to get something similar what libquvi did. Undocumented because it might change a lot, or even be removed. To give an idea what it does, a Lua script could do the following: -- type ID priority mp.commandv("hook_add", "on_load", 0, 0) mp.register_script_message("hook_run", function(param, param2) -- param is "0", the user-chosen ID from the hook_add command -- param2 is the magic value that has to be passed to finish -- the hook mp.resume_all() -- do something, maybe set options that are reset on end: mp.set_property("file-local-options/name", "value") -- or change the URL that's being opened: local url = mp.get_property("stream-open-filename") mp.set_property("stream-open-filename", url .. ".png") -- let the player (or the next script) continue mp.commandv("hook_ack", param2) end)
* client API: minor optimizations for property notificationwm42014-08-021-0/+4
| | | | | | | | | | | | | | | | | | | | | Internally, there are two mechanisms which can trigger property notification as used with "observed" properties in the client API. The first mechanism associates events with a group of properties that are potentially changed by a certain event. mp_event_property_change[] declares these associations, and maps each event to a set of strings. When an event happens, the set of strings is matched against the list of observed properties of each client. Make this more efficient by comparing bitsets of events instead. This way, only a bit-wise "and" is needed for each observed property. Even better, we can completely skip clients which have no observed properties that match. The second mechanism just updates individual properties explicitly by name. Optimize this by using the property index instead. It would be nice if we could reuse the first mechanism for the second one, but there are too many properties to fit into a 64 bit mask. (Though the limit on 64 events might get us into trouble later...)
* command: add a property that returns a list of all propertieswm42014-08-021-3/+0
| | | | Also remove the undocumented Lua mp.property_list() function.
* client API: make "cache" property and similar observablewm42014-07-311-0/+3
| | | | | | Achieve this by polling. Will be used by the OSC. Basically a bad hack - but the point is that the mpv core itself is in the best position to improve this later.
* command: redo the property typewm42014-06-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Instead of absuing m_option to store the property list, introduce a separate type for properties. m_option is still used to handle data types. The property declaration itself now never contains the option type, and instead it's always queried with M_PROPERTY_GET_TYPE. (This was already done with some properties, now all properties use it.) This also fixes that the function signatures did not match the function type with which these functions were called. They were called as: int (*)(const m_option_t*, int, void*, void*) but the actual function signatures were: int (*)(m_option_t*, int, void*, MPContext *) Two arguments were mismatched. This adds one line per property implementation. With additional the reordering of the parameters, this makes most of the changes in this commit.
* client API: report success status when running commandswm42014-06-011-1/+1
| | | | | | Until now, an error was reported only if the command couldn't be parsed. Attempt to do more fine-grained reporting. This is not necessarily perfect, but it's an improvement.
* command: add const to mp_notify_propertywm42014-06-011-1/+1
|
* client API: add a way to notify clients of property changeswm42014-04-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | This turned out ridiculously complex. I think it will have to be simplified some day. Main reason for the complexity are: - filtering properties by forcing clients to observe individual properties explicitly (to avoid spamming clients with changes they don't want) - optional retrieval of property value with the notification (the basic idea was that this is more user friendly) - allowing to the client to specify a format in which the value should be retrieved (because if a property changes its type, the client API couldn't convert it properly, and compatibility would break) I don't know yet which of these are important, and everything could change. In particular, the interface and semantics should be adjusted to reduce the implementation complexity. While I consider the API complete, there could (and probably will) be bugs left. Also while the implementation is complete, it's inefficient. The complexity of the property matching is O(a*b*c) with a clients, b observed properties, and c properties changing at once. I threw away an earlier implementation using bitmasks, because it was too unwieldy.
* options: handle escape sequences in e.g. --playing-msg differentlywm42014-02-201-0/+1
| | | | | | | | | | M_OPT_PARSE_ESCAPES was pretty stupid, and broke the (useful) assumption that string variables contain exactly the same value as set by the option. Simplify it, and move escape handling to the place where it's used. Escape handling itself is not terribly useful, but still allows useful things like multiline custom OSD with "\n".
* lua: port to client APIwm42014-02-101-1/+0
| | | | | | | | | | | | | | | | This is partial only, and it still accesses some MPContext internals. Specifically, chapter and track lists are still read directly, and OSD access is special-cased too. The OSC seems to work fine, except using the fast-forward/backward buttons. These buttons behave differently, because the OSC code had certain assumptions how often its update code is called. The Lua interface changes slightly. Note that this has the odd property that Lua script and video start at the same time, asynchronously. If this becomes an issue, explicit synchronization could be added.
* Add a client APIwm42014-02-101-13/+1
| | | | | | | Add a client API, which is intended to be a stable API to get some rough control over the player. Basically, it reflects what can be done with input.conf commands or the old slavemode. It will replace the old slavemode (and enable the implementation of a new slave protocol).
* lua: add playback-start eventwm42014-01-201-0/+1
|
* m_property: mp_msg conversionswm42013-12-211-1/+2
| | | | | Includes some semi-crappy hacks to avoid changing too much code for this conversion (allowing NULL log argument for m_property_do()).
* Move mpvcore/player/ to player/wm42013-12-171-0/+50
