* lua: expose mpv_abort_async_command()wm42018-05-241-0/+9
| | | | Also somewhat cleans up mp.command_native_async() error handling.
* lua: reimplement mp.subprocess_detached() by invoking the "run" commandwm42018-05-241-30/+0
| | | | | | | | The "run" command is old. I'm not sure why the separate Lua implementation was added. But maybe it as because the "run" command used to be limited to a small number of arguments. This limit has been removed a while ago. In any case, the old implementation is not needed anymore.
* lua: reimplement mp.subprocess() by invoking the new subprocess commandwm42018-05-241-78/+0
| | | | | | | We keep mp.subprocess() with roughly the same semantics for compatibility with scripts (including the internal ytdl script). Seems to work with rhe ytdl wrapper. Not tested further.
* lua: expose async commandswm42018-05-241-0/+19
| | | | Might be useful for some.
* client API: add a first class hook API, and deprecate old APIwm42018-03-261-0/+24
| | | | | | | | | | | | | | | As it turns out, there are multiple libmpv users who saw a need to use the hook API. The API is kind of shitty and was never meant to be actually public (it was mostly a hack for the ytdl script). Introduce a proper API and deprecate the old one. The old one will probably continue to work for a few releases, but will be removed eventually. There are some slight changes to the old API, but if a user followed the manual properly, it won't break. Mostly untested. Appears to work with ytdl_hook.
* lua+js: Implement utils.getpid()sfan52018-02-131-0/+8
| | | | | | | Usable for uniquely identifying mpv instances from subprocesses, controlling mpv with AppleScript, ... Adds a new mp_getpid() wrapper for cross-platform reasons.
* msg: reinterpret a bunch of message levelsNiklas Haas2017-12-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | I've decided that MP_TRACE means “noisy spam per frame”, whereas MP_DBG just means “more verbose debugging messages than MSGL_V”. Basically, MSGL_DBG shouldn't create spam per frame like it currently does, and MSGL_V should make sense to the end-user and provide mostly additional informational output. MP_DBG is basically what I want to make the new default for --log-file, so the cut-off point for MP_DBG is if we probably want to know if for debugging purposes but the user most likely doesn't care about on the terminal. Also, the debug callbacks for libass and ffmpeg got bumped in their verbosity levels slightly, because being external components they're a bit less relevant to mpv debugging, and a bit too over-eager in what they consider to be relevant information. I exclusively used the "try it on my machine and remove messages from MSGL_* until it does what I want it to" approach of refactoring, so YMMV.
* lua+js: implement utils.file_info()TSaaristo2017-12-131-0/+43
| | | | | | | | | | | | | | | This commit introduces mp.utils.file_info() for querying information on file paths, implemented for both Lua and Javascript. The function takes a file path as an argument and returns a Lua table / JS object upon success. The table/object will contain the values: mode, size, atime, mtime, ctime and the convenience booleans is_file, is_dir. On error, the Lua side will return `nil, error` and the Javascript side will return `undefined` (and mark the last error). This feature utilizes the already existing cross-platform `mp_stat()` function.
* lua: integrate stats.lua scriptJulian2017-10-091-0/+3
| | | | | | | | | Signed-off-by: wm4 <wm4@nowhere> Rename --stats to --load-stats-overlay and add an entry to options.rst over the original commit. Signed-off-by: wm4 <wm4@nowhere>
* scripting: expand --script filename for C pluginsHoyon Mak2017-06-091-4/+2

* lua: increase subprocess stdout limit to 64MBRicardo Constantino2017-05-041-1/+1

* lua: close directory after reading its entriesWilliam Woodruff2017-01-171-0/+1
| | | | Fixes #4045.
* scripting: minor logging improvementswm42017-01-141-0/+1
| | | | | | | | Give scripting backends a proper name, instead of calling everything "scripts". Log client exit directly in client.c, as that is more general (doesn't change actual output).
* client API: turn mpv_suspend() and mpv_resume() into stubswm42016-11-221-11/+1
| | | | | | | | | | | As threatened by the API changes document. This commit also removes or stubs equivalent calls in IPC and Lua scripting. The stubs are left to maintain ABI compatibility. The semantics of the API functions have been close enough to doing nothing that this probably won't even break existing API users. Probably.
* lua: complain loudly if Lua state creation failswm42016-09-251-1/+3
| | | | | | | This should normally happen only if memory allocation for the state happens, which should be extremely rare. But with Luajit on OSX, it can happen if the magic compiler flags required by Luajit were not passed to mpv compilation. Print an error to reduce confusion.
* lua: fix array detectionwm42016-09-241-2/+2
| | | | | | | This was dumb and could return something like "{name=123}" as an array. Also, fix the error message if a key is not a string. lua_typename() takes a type directly, not a stack item.
* lua: expose subprocess_detachedrr-2016-09-211-0/+32

* player: kill associated OSD and key bindings when removing a scriptwm42016-09-201-1/+0
| | | | | The former was done already for Lua scripts, but move it to the generic code.
* client API: declare mpv_suspend/mpv_resume deprecatedwm42016-09-161-0/+2
| | | | | | | They're useless, and I have no idea what they're actually supposed to do (wrt. pending input processing changes). Also remove their implicit uses from the IPC handlers.
* player, ao, vo: don't call mp_input_wakeup() directlywm42016-09-161-1/+1
| | | | | | | | | | | | | 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).
* osd: cleanup: make OSDTYPE_ constants private to OSD codewm42016-03-081-2/+2
| | | | | | No need to have them everywhere. The only exception/annoyance is MAX_OSD_PARTS, which is now basically duplicated (and at runtime initialization is checked with an assert()).
* osd, lua: manage multiple ASS overlays set with set_osd_ass() callswm42016-03-081-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Until now, there was only 1 global ASS overlay that could be set by all scripts. This was often perceived as bug when multiple scripts tried to set their own ASS overlay. This was kind of hard to solve because the script could set its own ASS PlayResX/Y, which makes it impossible to share a single ASS_Renderer for multiple scripts. The OSC unfortunately makes use of this feature (and unfortunately can't be fixed because it's a POS), so we're stuck with this complication. Implement the worst-case solution and fix this by creating separate ASS track and renderer objects for each script that wants to set an ASS overlay. The z-order is decided by the order the scripts set their text first. This is essentially random, unless you do it at script init, and you pass scripts in a specific order. Script initialization is currently serialized (as a feature), so the first loaded script gets lowest Z-order. The Lua script API interestingly remains the same. (And also will remain undocumented, unsupported, and potentially volatile.)
* osd, lua: remove weird OSD scalingwm42016-03-071-26/+10
| | | | | | | | | | | | | | | | | | | | | Do not scale OSD mouse input to the ASS OSD script resolution. The original idea of this mechanism was that the user doesn't have to care about the actual resolution of anything, and can just use the OSD resolution consistently. But this made things worse. Remove the implicit scaling, and always use the screen resolution. (Except with --vo=xv, where additional scaling is forced upon everything.) Drop get_osd_resolution(). There is no replacement. Rename get_screen_size() and get_screen_margins() to use "osd" instead of "screen". For anything but --vo=xv these are equivalent, but with --vo=xv the OSD resolution has additional implicit scaling. Add code to osc.lua which emulates the old behavior. Note that none of the changed functions were public API, so implicit breakage of scripts which used it is just going to happen.
* Relicense some non-MPlayer source files to LGPL 2.1 or laterwm42016-01-191-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This covers source files which were added in mplayer2 and mpv times only, and where all code is covered by LGPL relicensing agreements. There are probably more files to which this applies, but I'm being conservative here. A file named ao_sdl.c exists in MPlayer too, but the mpv one is a complete rewrite, and was added some time after the original ao_sdl.c was removed. The same applies to vo_sdl.c, for which the SDL2 API is radically different in addition (MPlayer supports SDL 1.2 only). common.c contains only code written by me. But common.h is a strange case: although it originally was named mp_common.h and exists in MPlayer too, by now it contains only definitions written by uau and me. The exceptions are the CONTROL_ defines - thus not changing the license of common.h yet. codec_tags.c contained once large tables generated from MPlayer's codecs.conf, but all of these tables were removed. From demux_playlist.c I'm removing a code fragment from someone who was not asked; this probably could be done later (see commit 15dccc37). misc.c is a bit complicated to reason about (it was split off mplayer.c and thus contains random functions out of this file), but actually all functions have been added post-MPlayer. Except get_relative_time(), which was written by uau, but looks similar to 3 different versions of something similar in each of the Unix/win32/OSX timer source files. I'm not sure what that means in regards to copyright, so I've just moved it into another still-GPL source file for now. screenshot.c once had some minor parts of MPlayer's vf_screenshot.c, but they're all gone.
* mpv_talloc.h: rename from talloc.hDmitrij D. Czarkoff2016-01-111-1/+1
| | | | This change helps avoiding conflict with talloc.h from libtalloc.
* osd: delay libass initialization as far as possiblewm42015-09-071-0/+2
| | | | | | | | | | | | Until now, most OSD objects created the associated ASS_Renderer instance as soon as possible, even if nothing was going to be rendered. Maybe this was even intentional. Change this for the sake of lowering resource usage, and strictly initialize ASS_Renderer only when it's really needed. For the OSC, initialization has to be forced, because of the insane mechanism for translating mouse coordinates to OSD coordinates.
* lua: implement input_enable_section/input_disable_section via commandswm42015-08-061-34/+0
| | | | | | | | | | | | | | | Removes some more internal API calls from the Lua scripting backend. Which is good, because ideally the scripting backend would use libmpv functions only. One awkwardness is that mouse sections are still not supported by the public commands (and probably will never), so flags like allow-hide- cursor make no sense to an outside user. Also, the way flags are passed to the Lua function changes. But that's ok, because they're only undocumented internal functions, and not supposed to be used by script users. osc.lua only does due to historical reasons.
* lua: make mp.input_define_section use the define-section commandwm42015-08-061-21/+0
|
* subprocess, lua: export whether the process was killed by uswm42015-06-271-0/+2
| | | | | | | | We want to distinguish actual errors, and just aborting the program intentionally. Also be a bit more careful with handling the wait() exit status: do not called WEXITSTATUS() without checking WIFEXITED() first.
* lua: support MPV_END_FILE_REASON_REDIRECTwm42015-06-111-0/+1
| | | | And also add the missing "unknown" entry to the manpage.
* lua: export end-file event fieldswm42015-06-111-0/+20
|
* path: make mp_path_join accept normal C stringswm42015-05-091-2/+2
| | | | | Instead of bstr. Most callers of this function do not need bstr. The bstr version of this function is now mp_path_join_bstr().
* lua: remove deprecated "lua" sub directorieswm42015-05-091-10/+4
| | | | | The compatibility code and the deprecation warning were at least in releases 0.8 and 0.9 - time to get rid of them.
* lua: add utils.format_json() functionwm42015-04-221-0/+18
| | | | Requested. Why not.
* client API: add MPV_FORMAT_BYTE_ARRAY typewm42015-04-201-0/+3
| | | | | | | | | | | | This will be used in the following commit, which adds screenshot_raw. The reasoning is that this will be better for binding scripting languages. One could special-case the screenshot_raw commit and define fixed semantics for passing through a pointer using the current API, like formatting a pointer as string. But that would be ridiculous and unclean.
* lua: reject Lua 5.3wm42015-04-011-0/+5
| | | | | | | | | | | | | | It simply doesn't work, and is hard to make work. Lua 5.3 is a different language from 5.1 and 5.2, and is different enough to make adding support a major issue. Most importantly, 5.3 introduced integer types, which completely mess up any code which deals with numbers. I tried to make this a compile time check, but failed. Still at least try to avoid selecting the 5.3 pkg-config package when the generic "lua" name is used (why can't Lua upstream just provide an official .pc file...). Maybe this actually covers all cases. Fixes #1729 (kind of).
* build: make posix_spawn() mandatorywm42015-03-301-4/+0
| | | | | | | It was already accidentally used unconditionally by command.c. Apparently this worked well for us, so don't change anything about, but should it be unavailable, fail at configure time instead of compile time.
* lua: replace getcwd() implementationwm42015-03-241-14/+0
|
* Lua: add mp.get_screen_margins().torque2015-03-011-0/+12
| | | | | | When used with mp.get_screen_size(), mp.get_screen_margins() allows a Lua script to determine what portion of the mpv window actually has the video in it.
* client API: be more lenient about mpv_suspend/resume mismatcheswm42014-12-151-27/+6
| | | | | | | | | | | | Before this commit, this was defined to trigger undefined behavior. This was nice because it required less code; but on the other hand, Lua as well as IPC support had to check these things manually. Do it directly in the API to avoid code duplication, and to make the API more robust. (The total code size still grows, though...) Since all of the failure cases were originally meant to ruin things forever, there is no way to return error codes. So just print the errors.
* lua: cosmetics: fix some include directiveswm42014-12-151-3/+2
| | | | | | Apparently, the atomics were used by the win32 subprocess code. This code was moved to a separate file, but the atomics.h include was forgotten.
* options: deprecate 'lua' based options/dirs for 'script'Avi Halachmi (:avih)2014-12-151-4/+10
| | | | | | | | | | | | - --lua and --lua-opts change to --script and --script-opts - 'lua' default script dirs change to 'scripts' - DOCS updated - 'lua-settings' dir was _not_ modified The old lua-based names/dirs still work, but display a warning. Signed-off-by: wm4 <wm4@nowhere>
* lua: fix broken error messagewm42014-12-021-1/+1
| | | | | luaL_error() doesn't support %.*s, because it uses Lua's own format string mechanism that just looks like the C one. Just drop this part.
* lua, ipc: remove leftoverswm42014-11-241-9/+0
| | | | | | MPV_EVENT_SCRIPT_INPUT_DISPATCH is now unused/deprecated. Also remove a debug-print from defaults.lua.
* lua: subprocess: move to osdep/subprocess-{win,posix}.cJames Ross-Gowan2014-11-221-478/+3
| | | | | | The subprocess code was already split into fairly general functions, separate from the Lua code. It's getting pretty big though, especially the Windows-specific parts, so move it into its own files.
* lua: subprocess: use macros for SetHandleInformationJames Ross-Gowan2014-11-221-1/+2
| | | | | Apparently both parameters refer to the same set of flags (the first is a mask for which flags to set.)
* lua: subprocess: fix handle inheritance race conditionJames Ross-Gowan2014-11-221-11/+87
| | | | | | | | | | | | | | | Normally, when creating a process with inherited handles on Windows, the process inherits all inheritable handles from the parent, including ones that were created on other threads. This can cause a race condition, where unintended handles are copied into the new process, preventing them from being closed correctly while the process is running. The only way to prevent this on Windows XP was to serialise the creation of all inheritable handles, which is clearly unacceptable for libmpv. Windows Vista solves this problem by allowing programs to specify exactly which handles are inherited, so do that on Vista and up. See http://blogs.msdn.com/b/oldnewthing/archive/2011/12/16/10248328.aspx
* lua: subprocess: fix Ctrl+C handling on WindowsJames Ross-Gowan2014-11-221-3/+11
| | | | | | | | | | | | The CREATE_NO_WINDOW flag is used to prevent the subprocess from creating an empty console window when mpv is not running in a console. When mpv is running in a console, it causes the subprocess to detach itself, and prevents it from seeing Ctrl+C events, so it hangs around in the background after mpv is killed. Fix this by only specifying CREATE_NO_WINDOW when mpv is not attached to a console. When it is attached to a console, subprocesses will automatically inherit the console and correctly receive Ctrl+C events.
* lua: subprocess: cancel pending I/O before returnJames Ross-Gowan2014-11-221-2/+7
| | | | | | | I'm not sure if this is necessary, but it can't hurt, and it's what you're supposed to do before leaving the stack frame that contains the OVERLAPPED object and the buffer. If there is no pending I/O, CancelIo will do nothing and GetOverlappedResult will silently fail.
* player: integrate ytdl_hook.luawm42014-11-191-0/+3

* lua: subprocess: support cancellation on WindowsJames Ross-Gowan2014-11-181-1/+9
|
* lua: subprocess: use overlapped I/O on WindowsJames Ross-Gowan2014-11-181-56/+133
| | | | | | | Instead of threads, use overlapped (asynchronous) I/O to read from both stdout and stderr. Like in d0643fa, stdout and stderr could be closed at different times, so a sparse_wait function is added to wrap WaitForMultipleObjects and skip NULL handles.
* lua: subprocess: remove minor code duplicationwm42014-11-161-31/+22
| | | | | | | | Now that the code for stderr and stdout does exactly the same things, and the specialization is in the callbacks, this is blatantly duplicated. Also, define a typedef for those callbacks to reduce the verbosity.
* lua: subprocess: add Windows implementationJames Ross-Gowan2014-11-161-46/+257
| | | | Doesn't handle mp_cancel yet.
* lua: subprocess: fix dumbwm42014-10-261-1/+1
|
* lua: subprocess: tunnel stderr through mp_logwm42014-10-261-20/+63
| | | | | | | | | | | Pretty much a fringe-feature, but also it's awkward if something appears on the terminal with no indication for the source. This is made quite awkward by the fact that stderr and stdout could be closed at different times, and that poll() doesn't accept "holes" in its FD list. Invalid (.e.g negative) FDs just make it return immediately, as required by the standard. So sparse_poll() takes care of the messy details.
* lua: parse_json(): fix inverted condition for trail argumentwm42014-10-261-1/+1
| | | | It accidentally had the opposite meaning.
* lua: subprocess: don't distinguish pipe errors/EOFwm42014-10-261-7/+4
| | | | | | | What was the purpose of that? Probably none. Also simplify another thing: if we get the cancel signal through FD, there's no reason to check it separately.
* lua: fix some more lua_tostring() mistakeswm42014-10-251-1/
