* audio: move to decoder wrapperwm42018-01-301-8/+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: rewrite filtering glue codewm42018-01-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of the old vf.c code. Replace it with a generic filtering framework, which can potentially handle more than just --vf. At least reimplementing --af with this code is planned. This changes some --vf semantics (including runtime behavior and the "vf" command). The most important ones are listed in interface-changes. vf_convert.c is renamed to f_swscale.c. It is now an internal filter that can not be inserted by the user manually. f_lavfi.c is a refactor of player/lavfi.c. The latter will be removed once --lavfi-complex is reimplemented on top of f_lavfi.c. (which is conceptually easy, but a big mess due to the data flow changes). The existing filters are all changed heavily. The data flow of the new filter framework is different. Especially EOF handling changes - EOF is now a "frame" rather than a state, and must be passed through exactly once. Another major thing is that all filters must support dynamic format changes. The filter reconfig() function goes away. (This sounds complex, but since all filters need to handle EOF draining anyway, they can use the same code, and it removes the mess with reconfig() having to predict the output format, which completely breaks with libavfilter anyway.) In addition, there is no automatic format negotiation or conversion. libavfilter's primitive and insufficient API simply doesn't allow us to do this in a reasonable way. Instead, filters can use f_autoconvert as sub-filter, and tell it which formats they support. This filter will in turn add actual conversion filters, such as f_swscale, to perform necessary format changes. vf_vapoursynth.c uses the same basic principle of operation as before, but with worryingly different details in data flow. Still appears to work. The hardware deint filters (vf_vavpp.c, vf_d3d11vpp.c, vf_vdpaupp.c) are heavily changed. Fortunately, they all used refqueue.c, which is for sharing the data flow logic (especially for managing future/past surfaces and such). It turns out it can be used to factor out most of the data flow. Some of these filters accepted software input. Instead of having ad-hoc upload code in each filter, surface upload is now delegated to f_autoconvert, which can use f_hwupload to perform this. Exporting VO capabilities is still a big mess (mp_stream_info stuff). The D3D11 code drops the redundant image formats, and all code uses the hw_subfmt (sw_format in FFmpeg) instead. Although that too seems to be a big mess for now. f_async_queue is unused.
* build: move copyright statement to a shared locationwm42018-01-011-0/+1
| | | | | | | 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.)
* player: fix --lavfi-complex freezewm42017-08-111-4/+5
| | | | | | | | | | | | | | | | | | | Commit 0e0b87b6f3297 fixed that dropped packets did not trigger further work correctly. But it also made trivial --lavfi-complex freeze. The reason is that the meaning if DATA_AGAIN was overloaded: the decoders meant that they should be called again, while lavfi.c meant that other outputs needed to be checked again. Rename the latter meaning to DATA_STARVE, which means that the current input will deliver no more data, until "other" work has been done (like reading other outputs, or feeding input). The decoders never return DATA_STARVE, because they don't get input from the player core (instead, they get it from the demuxer directly, which is why they still can return DATA_WAIT). Also document the DATA_* semantics in the enum. Fixes #4746.
* vo_opengl: further GL API use separationwm42017-08-071-0/+1
| | | | | | | | | | | | | | | Move multiple GL-specific things from the renderer to other places like vo_opengl.c, vo_opengl_cb.c, and ra_gl.c. The vp_w/vp_h parameters to gl_video_resize() make no sense anymore, and are implicitly part of struct fbodst. Checking the main framebuffer depth is moved to vo_opengl.c. For vo_opengl_cb.c it always assumes 8. The API user now has to override this manually. The previous heuristic didn't make much sense anyway. The only remaining dependency on GL is the hwdec stuff, which is harder to change.
* common, vo_opengl: add/use helper for formatted strings on the stackwm42017-07-241-0/+8
| | | | | | | | | | | Seems like I really like this C99 idiom. No reason not to generalize it do snprintf(). Introduce mp_tprintf(), which basically this idiom to snprintf(). This macro looks like it returns a string that was allocated with alloca() on the caller site, except it's portable C99/C11. (And unlike alloca(), the result is valid only within block scope.) Use it in 2 places in the vo_opengl code. But it has the potential to make a whole bunch of weird looking code look slightly nicer.
* common.h: change license to LGPLwm42017-04-211-7/+7
| | | | | | | | | | | The only definitions from MPlayer code are the CONTROL_* defines (added in 7a2eec4b as part of libao2 - not part of libao), and MP_NOPTS_VALUE, which was added in e6338c58. The latter is by "michael", who has agreed under the condition that the core is LGPL, which has not happened yet, but considering the macro definition used to be different, has the same value and similar name to libavformat's AV_NOPTS_VALUE (which existed first, and as LGPL), and that this almost certainly not copyrightable, I'm assuming that this is fine.
* common: use char array for version stringwm42016-09-061-2/+2
| | | | | Use a char array instead of a pointer, which allows using the version variables in a constant context.
* common: add assert.h includewm42016-08-281-0/+1
| | | | Because why not.
* audio/video: merge decoder return valueswm42016-02-011-0/+7
| | | | | | Will be helpful for the coming filter support. I planned on merging audio/video decoding, but this will have to wait a bit longer, so only remove the duplicate status codes.
* mpv_talloc.h: rename from talloc.hDmitrij D. Czarkoff2016-01-111-1/+1
| | | | This change helps avoiding conflict with talloc.h from libtalloc.
* common: add mp_tag_str() utility functionwm42016-01-111-0/+3
* command: replace ROUND() with lrint()wm42015-12-261-2/+0
| | | | | lrint() pretty much does what ROUND() is supposed to do, but it's more precise.
* x11: query ICC profile based on center of windowNiklas Haas2015-04-291-0/+1
| | | | | | | | | | Right now, the default behavior is to pick the numerically lowest screen ID that overlaps the window in any way - but this means that mpv will decide to pick an ICC profile in a pretty arbitrary way even if the window only overlaps another screen by a single pixel. The new behavior is to query it based on the center of the window instead.

* Do not call strerror()wm42014-11-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | ...because everything is terrible. strerror() is not documented as having to be thread-safe by POSIX and C11. (Which is pretty much bullshit, because both mandate threads and some form of thread-local storage - so there's no excuse why implementation couldn't implement this in a thread-safe way. Especially with C11 this is ridiculous, because there is no way to use threads and convert error numbers to strings at the same time!) Since we heavily use threads now, we should avoid unsafe functions like strerror(). strerror_r() is in POSIX, but GNU/glibc deliberately fucks it up and gives the function different semantics than the POSIX one. It's a bit of work to convince this piece of shit to expose the POSIX standard function, and not the messed up GNU one. strerror_l() is also in POSIX, but only since the 2008 standard, and thus is not widespread. The solution is using avlibc (libavutil, by its official name), which handles the unportable details for us, mostly. We avoid some pain.
* common: fix version variable declarationswm42014-11-021-2/+2
| | | | This was stupid.
* Move compat/ and bstr/ directory contents somewhere elsewm42014-08-291-1/+1
| | | | | | | | | bstr.c doesn't really deserve its own directory, and compat had just a few files, most of which may as well be in osdep. There isn't really any justification for these extra directories, so get rid of them. The compat/libav.h was empty - just delete it. We changed our approach to API compatibility, and will likely not need it anymore.
* common: change MP_NOPTS_VALUE definitionwm42014-05-101-2/+2
| | | | | | | | | Use the exact floating point value, instead of a broken integer constant. The expression calculating the constant probably relied on undefined behavior, because it left-shifts a negative value. This also changes the type of the constant to double, which is perfectly fine, and maybe better than an integer constant.
* common: change mp_snprintf_append semanticswm42014-05-051-1/+1
| | | | | | | | Make it more suitable for chaining. This means a function formatting a value to a string using a static buffer can work exactly like mp_snprintf_append itself. Also rename it to mp_snprintf_cat, because that's shorter.
* common: add mp_snprintf_append() utility functionwm42014-04-291-0/+4
* common: add some helper macroswm42014-03-071-0/+3
* common: drop mp_append_utf8_buffer()wm42013-12-301-2/+0
* common: simplify and optimize string escape parsingwm42013-12-301-1/+7
| | | | | | | | | | | This code is shared between input.conf parser and option parser. Until now, the performance didn't really matter. But I want to use this code for JSON parsing too, and since JSON will have to be parsed a lot, it should probably try to avoid realloc'ing too much. This commit moves parsing of C-style escaped strings into a common function, and allows using it in a way realloc can be completely avoided, if the already allocated buffer is large enough.
* Don't include version.h from make options.cwm42013-12-221-2/+2
| | | | | | | | | I find this annoying. It's the reason common/version.c exists at all. options.c did this for the user agent, which contains the version number. Because not including version.h means you can't build the user agent and use it in mp_default_opts anymore, do something rather awkward in main.c to initialize the default user agent.
