* player: get rid of mpv_global.optswm42018-05-241-5/+5
| | | | | | | | This was always a legacy thing. Remove it by applying an orgy of mp_get_config_group() calls, and sometimes m_config_cache_alloc() or mp_read_option_raw(). win32 changes untested.
* path: don't access global option structwm42018-05-241-0/+1
| | | | | | | The path functions need to access the option that forces non-default config directories. Just add it as a field to mpv_global - it seems justified. The accessed options were always enforced as immutable after init, so there's not much of a change.
* ao: use a local option structwm42018-05-241-1/+3
| | | | Instead of accessing MPOpts.
* player: make playback termination asynchronouswm42018-05-241-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, stopping playback aborted the demuxer and I/O layer violently by signaling mp_cancel (bound to libavformat's AVIOInterruptCB mechanism). Change it to try closing them gracefully. The main purpose is to silence those libavformat errors that happen when you request termination. Most of libavformat barely cares about the termination mechanism (AVIOInterruptCB), and essentially it's like the network connection is abruptly severed, or file I/O suddenly returns I/O errors. There were issues with dumb TLS warnings, parsers complaining about incomplete data, and some special protocols that require server communication to gracefully disconnect. We still want to abort it forcefully if it refuses to terminate on its own, so a timeout is required. Users can set the timeout to 0, which should give them the old behavior. This also removes the old mechanism that treats certain commands (like "quit") specially, and tries to terminate the demuxers even if the core is currently frozen. This is for situations where the core synchronized to the demuxer or stream layer while network is unresponsive. This in turn can only happen due to the "program" or "cache-size" properties in the current code (see one of the previous commits). Also, the old mechanism doesn't fit particularly well with the new one. We wouldn't want to abort playback immediately on a "quit" command - the new code is all about giving it a chance to end it gracefully. We'd need some sort of watchdog thread or something equally complicated to handle this. So just remove it. The change in osd.c is to prevent that it clears the status line while waiting for termination. The normal status line code doesn't output anything useful at this point, and the code path taken clears it, both of which is an annoying behavior change, so just let it show the old one.
* player: change the role of the "stop_play" and "playing" variablewm42018-05-241-0/+1
| | | | | | | | | | | | | | | | | Before this, mpctx->playing was often used to determine whether certain new state could be added to the playback state. In particular this affected external files (which added tracks and demuxers). The variable was checked to prevent that they were added before the corresponding uninit code. We want to make a small part of uninit asynchronous, but mpctx->playing needs to stay in the place where it is. It can't be used for this purpose anymore. Use mpctx->stop_play instead. Make it never have the value 0 outside of loading/playback. On unloading, it obviously has to be non-0. Change some other code in playloop.c to use this, because it seems slightly more correct. But mostly this is preparation for the following commit.
* misc: move mp_cancel from stream.c to thread_tools.cwm42018-05-241-1/+1
| | | | | | | | | | | | It seems a bit inappropriate to have dumped this into stream.c, even if it's roughly speaking its main user. At least it made its way somewhat unfortunately to other components not related to the stream or demuxer layer at all. I'm too greedy to give this weird helper its own file, so dump it into thread_tools.c. Probably a somewhat pointless change.
* command: add a way to abort asynchronous commandswm42018-05-241-0/+2
| | | | | | | | | | | | Many asynchronous commands are potentially long running operations, such as loading something from network or running a foreign process. Obviously it shouldn't just be possible for them to freeze the player if they don't terminate as expected. Also, there will be situations where you want to explicitly stop some of those operations explicitly. So add an infrastructure for this. Commands have to support this explicitly. The next commit uses this to actually add support to a command.
* player: rename "lock" to "abort_lock"wm42018-05-241-2/+2
| | | | | | If a struct as large as MPContext contains a field named "lock", it creates the impression that it is the primary lock for MPContext. This is wrong, the lock just protects a single field.
* command: add infrastructure for async commandswm42018-05-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | This enables two types of command behavior: 1. Plain async behavior, like "loadfile" not completing until the file is fully loaded. 2. Running parts of the command on worker threads, e.g. for I/O, such as "sub-add" doing network accesses on a thread while the core continues. Both have no implementation yet, and most new code is actually inactive. The plan is to implement a number of useful cases in the following commits. The most tricky part is handling internal keybindings (input.conf) and the multi-command feature (concatenating commands with ";"). It requires a bunch of roundabout code to make it do the expected thing in combination with async commands. There is the question how commands should be handled that come in at a higher rate than what can be handled by the core. Currently, it will simply queue up input.conf commands as long as memory lasts. The client API is limited by the size of the reply queue per client. For commands which require a worker thread, the thread pool is limited to 30 threads, and then will queue up work in memory. The number is completely arbitrary.
* build: make encoding mode non-optionalwm42018-05-031-6/+0
| | | | Makes it easier to not break the build by confusing the ifdeffery.
* encode: rewrite half of itwm42018-04-291-4/+3
| | | | | | | | | | | | | The main change is that we wait with opening the muxer ("writing headers") until we have data from all streams. This fixes race conditions at init due to broken assumptions in the old code. This also changes a lot of other stuff. I found and fixed a few API violations (often things for which better mechanisms were invented, and the old ones are not valid anymore). I try to get away from the public mutex and shared fields in encode_lavc_context. For now it's still needed for some timestamp-related fields, but most are gone. It also removes some bad code duplication between audio and video paths.
* encode: some more cleanupswm42018-04-291-1/+0
|
* client API: cleanup mpv_handle terminationwm42018-03-151-13/+3
| | | | | | | | | | | | | | | This changes how mpv_terminate_destroy() and mpv_detach_destroy() behave. The doxygen in client.h tries to point out the differences. The goal is to make this more useful to the API user (making it behave like refcounting). This will be refined in follow up commits. Initialization is unfortunately closely tied to termination, so that changes as well. This also removes earlier hacks that make sure that some parts of FFmpeg initialization are run in the playback thread (instead of the user's thread). This does not matter with standard FFmpeg, and I have no reason to care about this anymore.
* player: move locale check to mp_create()wm42018-03-151-0/+19
| | | | | | The intention is to reduce annoying differences between mpv CLI and libmpv, and there's no reason to have the locale check only in libmpv (although it doesn't help with any real issues either).
* player: shuffle around CLI exit code handlingwm42018-03-151-57/+43
| | | | | Remove the weird prepare_exit_cplayer() function, and fold the contents into mpv_main() and mp_initialize().
* player: add warning comment about ignoring ABI safetywm42018-03-031-0/+3
| | | | | At least ffmpeg_garbage() uses sizeof(AVFrameSideData), which is not included in the ABI, but there's no ABI-safe alternative either.
* client API: deprecate opengl-cb API and introduce a replacement APIwm42018-02-281-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The purpose of the new API is to make it useable with other APIs than OpenGL, especially D3D11 and vulkan. In theory it's now possible to support other vo_gpu backends, as well as backends that don't use the vo_gpu code at all. This also aims to get rid of the dumb mpv_get_sub_api() function. The life cycle of the new mpv_render_context is a bit different from mpv_opengl_cb_context, and you explicitly create/destroy the new context, instead of calling init/uninit on an object returned by mpv_get_sub_api(). In other to make the render API generic, it's annoyingly EGL style, and requires you to pass in API-specific objects to generic functions. This is to avoid explicit objects like the internal ra API has, because that sounds more complicated and annoying for an API that's supposed to never change. The opengl_cb API will continue to exist for a bit longer, but internally there are already a few tradeoffs, like reduced thread-safety. Mostly untested. Seems to work fine with mpc-qt.
* audio: move to decoder wrapperwm42018-01-301-1/+0
| | | | | | | | | | | | | | | | Use the decoder wrapper that was introduced for video. This removes all code duplication the old audio decoder wrapper had with the video code. (The audio wrapper was copy pasted from the video one over a decade ago, and has been kept in sync ever since by the power of copy&paste. Since the original copy&paste was possibly done by someone who did not answer to the LGPL relicensing, this should also remove all doubts about whether any of this code is left, since we now completely remove any code that could possibly have been based on it.) There is some complication with spdif handling, and a minor behavior change (it will restrict the list of codecs to spdif if spdif is to be used), but there should not be any difference in practice.
* video: make decoder wrapper a filterwm42018-01-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Move dec_video.c to filters/f_decoder_wrapper.c. It essentially becomes a source filter. vd.h mostly disappears, because mp_filter takes care of the dataflow, but its remains are in struct mp_decoder_fns. One goal is to simplify dataflow by letting the filter framework handle it (or more accurately, using its conventions). One result is that the decode calls disappear from video.c, because we simply connect the decoder wrapper and the filter chain with mp_pin_connect(). Another goal is to eventually remove the code duplication between the audio and video paths for this. This commit prepares for this by trying to make f_decoder_wrapper.c extensible, so it can be used for audio as well later. Decoder framedropping changes a bit. It doesn't seem to be worse than before, and it's an obscure feature, so I'm content with its new state. Some special code that was apparently meant to avoid dropping too many frames in a row is removed, though. I'm not sure how the source code tree should be organized. For one, video/decode/vd_lavc.c is the only file in its directory, which is a bit annoying.
* build: move copyright statement to a shared locationwm42018-01-011-3/+2
| | | | | | | Now macosx_menubar.m and mpv.rc (win32) use the same copyright string. (This is a bit roundabout, because mpv.rc can't use C constants. Also the C code wants to avoid rebuilding real source files if only version.h changed, so only version.c includes version.h.)
* Update copyright yearwm42018-01-011-1/+1

* main: fix typowm42018-01-011-1/+1
| | | | What the heck. This negated the entire check.
* player: log if NDEBUG is definedwm42017-11-041-0/+3
| | | | I sure want to know whether assert()s were unexpectedly not compiled in.
* player: change a minor code fragment to LGPLwm42017-10-041-5/+0
| | | | | | | Seems absurd to keep this under GPL, since it's only a tiny code fragment (that would always look the same, no matter if you rewrote it independently), but now I got proper permission from the original author anyway.
* vo_opengl: refactor into vo_gpuNiklas Haas2017-09-211-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is done in several steps: 1. refactor MPGLContext -> struct ra_ctx 2. move GL-specific stuff in vo_opengl into opengl/context.c 3. generalize context creation to support other APIs, and add --gpu-api 4. rename all of the --opengl- options that are no longer opengl-specific 5. move all of the stuff from opengl/* that isn't GL-specific into gpu/ (note: opengl/gl_utils.h became opengl/utils.h) 6. rename vo_opengl to vo_gpu 7. to handle window screenshots, the short-term approach was to just add it to ra_swchain_fns. Long term (and for vulkan) this has to be moved to ra itself (and vo_gpu altered to compensate), but this was a stop-gap measure to prevent this commit from getting too big 8. move ra->fns->flush to ra_gl_ctx instead 9. some other minor changes that I've probably already forgotten Note: This is one half of a major refactor, the other half of which is provided by rossy's following commit. This commit enables support for all linux platforms, while his version enables support for all non-linux platforms. Note 2: vo_opengl_cb.c also re-uses ra_gl_ctx so it benefits from the --opengl- options like --opengl-early-flush, --opengl-finish etc. Should be a strict superset of the old functionality. Disclaimer: Since I have no way of compiling mpv on all platforms, some of these ports were done blindly. Specifically, the blind ports included context_mali_fbdev.c and context_rpi.c. Since they're both based on egl_helpers, the port should have gone smoothly without any major changes required. But if somebody complains about a compile error on those platforms (assuming anybody actually uses them), you know where to complain.
* 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: revert multiple help outputwm42017-06-231-9/+8
| | | | | | | I think the idea is that you can pass multiple help options on the command line, and it will print them all, instead of printing only the first one and exiting. This was added in commit 43844d09, but the patch author could not be reached. Revert it, as it's not a critical feature.
* player: disable dumping configutation in LGPL modewm42017-06-231-0/+3
| | | | | | This was added in 0810e4275. The patch author did not reply (yet). Not sure if copyrightable, but I'm making the still existing C part GPL-only for now (in a previous commit).
* player: make sure version information is always included in --log-filewm42017-05-221-0/+5
| | | | | | | If --log-file was used in config files, this could be missing due to the exact timing when the messages are print, and when the options are applied. Fix this by always dumping the version again when a log file is opened.
* player: make screenshot commands honor the async flagwm42017-04-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | And also change input.conf to make all screenshots async. (Except the every-frame mode, which always uses synchronous mode and ignores the flag.) By default, the "screenshot" command is still asynchronous, because scripts etc. might depend on this behavior. This is only partially async. The code for determining the filename is still always run synchronously. Only encoding the screenshot and writing it to disk is asynchronous. We explicitly document the exact behavior as undefined, so it can be changed any time. Some of this is a bit messy, because I wanted to avoid duplicating the message display code between sync and async mode. In async mode, this is called from a worker thread, which is not safe because showing a message accesses the thread-unsafe OSD code. So the core has to be locked during this, which implies accessing the core and all that. So the code has weird locking calls, and we need to do core destruction in a more "controlled" manner (thus the outstanding_async field). (What I'd really want would be the OSD simply showing log messages instead.) This is pretty untested, so expect bugs. Fixes #4250.
* osx: initial Touch Bar supportAkemi2017-03-261-0/+5
|
* atomic: remove __atomic builtin usagewm42017-02-131-1/+1
| | | | | | | | Using these was a temporary solution while some compilers implemented the underlying atomic mechanisms, but not the C11 language parts (or that's what I guess). Not really useful for us anymore. Also, there is the slight risk of having subtly incorrect semantics by using potentially changing compiler internals and such.
* player: actually initialize/destroy MPContext.lockwm42017-01-221-0/+3
| | | | | | | | Seems like quite on oversight. For most of the better pthread implementations, pthread_mutex_init() on an already 0-initialized memory block is probably a no-op, but of course we should do things correctly. Also could setup analysis tools.
* player: restructure cancel callbackwm42017-01-181-1/+7
| | | | | | | | | | | | As preparation for file prefetching, we basically have to get rid of using mpctx->playback_abort for the main demuxer (i.e. the thing that can be prefetched). It can't be changed on a running demuxer, and always using the same cancel handle would either mean aborting playback would also abort prefetching, or that playback can't be aborted anymore. Make this more flexible with some refactoring. Thi is a quite shitty solution if you ask me, but YOLO.
* Update copyright yearwm42017-01-011-1/+1
| | | | What kind of bullshit forces you to do this every year anyway.
* options: change --h=... behaviorwm42016-12-161-1/+1
| | | | | Does not match a shell pattern anymore. Instead, a simple sub-string search is done.
* player: enable reading from stdin after loading input.confwm42016-09-291-5/+6
| | | | Someone requested this.
* win32: make --priority runtime-settableJames Ross-Gowan2016-09-281-9/+0
| | | | | | | | | | I'm not sure if this option affects anything or if it's a placebo, especially since the VO thread is now registered with MMCSS. Still, I think --priority=high may have helped back when I used mplayer2 on a netbook. It's also possible that encoding-mode users would want to set --priority=idle. Anyway, it was one of the last M_OPT_FIXED options, so fix that.
* player: allow opts in pseudo-gui set by the user to override user's defaultRicardo Constantino2016-09-261-2/+5
| | | | | | | | | | | | | | | | | | | | | This should still allow user-set default options to override built-in pseudo-gui while respecting user-set pseudo-gui options. Pros: - user option in default profile overrides built-in pseudo-gui's options Ex: screenshot-directory overrides built-in pseudo-gui's - user can "fix" pseudo-gui if some option like "force-window=no" is set in default by setting "force-window=yes" in [pseudo-gui] - `mpv --profile=pseudo-gui` will work as before Cons: - --show-profile=pseudo-gui won't display the built-in's options Original idea from wm4. Documentation edits mostly by wm4. Signed-off-by: wm4 <wm4@nowhere>
* player: fix intended pseudo-gui behaviorwm42016-09-231-3/+3
| | | | It's still supposed to be possible to customize the pseudo-gui section.
* player: do not let pseudo-gui override user config settingswm42016-09-231-0/+3
| | | | | | | | Seems like this confused users quite often. Instead of --profile=pseudo-gui, --player-operation-mode=pseudo-gui now has to be used to invoke pseudo GUI mode. The old way still works, and still behaves in the old way.
* options: make input options generally runtime-settablewm42016-09-211-9/+5
