Add initial Lua scripting support This is preliminary. There are still tons of issues, and any aspect of scripting may change in the future. I decided to merge this (preliminary) work now because it makes it easier to develop it, not because it's done. lua.rst is clear enough about it (plus some sarcasm). This requires linking to Lua. Lua has no official pkg-config file, but there are distribution specific .pc files, all with different names. Adding a non-pkg-config based configure test was considered, but we'd rather not. One major complication is that libquvi links against Lua too, and if the Lua version is different from mpv's, you will get a crash as soon as libquvi uses Lua. (libquvi by design always runs when a file is opened.) I would consider this the problem of distros and whoever builds mpv, but to make things easier for users, we add a terrible runtime test to the configure script, which probes whether libquvi will crash. This is disabled when cross-compiling, but in that case we hope the user knows what he is doing.

client API: report success status when running commands 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.

int run_command(struct MPContext *mpctx, struct mp_cmd *cmd);
command: when changing a property, allow showing an extra OSD message This is for properties that normally show a bar, and thus do not show an OSD message (as per classic mplayer behavior). Setting an extra_msg allows showing an OSD message anyway, except if OSD messages are explicitly suppressed. This refactors the whole show_property_osd() function a bit, and replaces the weird sep field with a more general method.

char *mp_property_expand_string(struct MPContext *mpctx, const char *str);
options: handle escape sequences in e.g. --playing-msg differently 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".

commands: cosmetic changes mostly to m_property.h The Doxygen-style documentation comments were nothing but bloat. Also move mp_property_do() and mp_property_print() to command.h, where they should belong, and fix their argument types. m_property.c/h is supposed to be generic, while command.h provides declarations specific to the mplayer core.

Add a client API 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).

player: fix audio-device-list updates 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.

void handle_command_updates(struct MPContext *mpctx);
client API: minor optimizations for property notification 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: make window-scale property observable 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.)

// Must start with the first unused positive value in enum mpv_event_id
// MPV_EVENT_* and MP_EVENT_* must not overlap.
client API: notify API user on event queue overflow 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.

INTERNAL_EVENT_BASE = 25,
command: send additional property change events in-between loading 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.

MP_EVENT_CHANGE_ALL,
command: make window-scale property observable Add a generic mechanism to the VO to relay "extra" events from VO to player.

(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.)

MP_EVENT_WIN_STATE,
audio: add device change notification for hotplugging 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.

MP_EVENT_AUDIO_DEVICES,
ao_coreaudio: add support for hotplug notifications 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.

};
client API: make "cache" property and similar observable 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: add a mechanism to allow scripts to intercept file loads 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)
