This commit adds a new build system based on waf. configure and Makefile
are deprecated effective immediately and someday in the future they will be
removed (they are still available by running ./old-configure).
You can find how the choice for waf came to be in `DOCS/waf-buildsystem.rst`.
TL;DR: we couldn't get the same level of abstraction and customization with
other build systems we tried (CMake and autotools).
For guidance on how to build the software now, take a look at README.md
and the cross compilation guide.
CREDITS:
This is a squash of ~250 commits. Some of them are not by me, so here is the
deserved attribution:
- @wm4 contributed some Windows fixes, renamed configure to old-configure
and contributed to the bootstrap script. Also, GNU/Linux testing.
- @lachs0r contributed some Windows fixes and the bootstrap script.
- @Nikoli contributed a lot of testing and discovered many bugs.
- @CrimsonVoid contributed changes to the bootstrap script.
The configure followed 5 different convetions of defines because the next guy
always wanted to introduce a new better way to uniform it[1]. For an
hypothetic feature 'hurr' you could have had:
* #define HAVE_HURR 1 / #undef HAVE_DURR
* #define HAVE_HURR / #undef HAVE_DURR
* #define CONFIG_HURR 1 / #undef CONFIG_DURR
* #define HAVE_HURR 1 / #define HAVE_DURR 0
* #define CONFIG_HURR 1 / #define CONFIG_DURR 0
All is now uniform and uses:
* #define HAVE_HURR 1
* #define HAVE_DURR 0
We like definining to 0 as opposed to `undef` bcause it can help spot typos
and is very helpful when doing big reorganizations in the code.

As preparation for resizing the window with input commands in the
following commit.
Since there are already so many functions which somehow resize the
window, add the word "highlevel" to the name of this new function.
This stopped working when the code was changed to create a window even
if --wid is used.
It appears we can't create our own window in this case, because in X11
there is no difference between a window with the root window as parent,
and a window that is managed by the WM. So make this (kind of worthless)
special case use the root window itself.
Trying to toggle the border during fullscreen (with "cycle border")
would leave the window stuck without border, and it couldn't be
restored. This was because vo_x11_decoration() always excepted to be
called when toggling the state, and thus confusing the contents of the
olddecor variable. Add got_motif_hints to hopefully prevent this.
Also, when changing the border, don't take fs in account. May break on
older/broken WMs, but all in all is in fact more robust and simpler,
because you do not need to update the border state manually when
returning from fullscreen.
This could cause the OSC to be displayed without mouse interaction: for
example, starting mpv with --fs, and putting the mouse to where the OSC
area is beforehand, would cause the OSC to appear and stay visible. We
don't want that. The simplest solution is not generating artificial
mouse move events from mouse enter events, because they make the OSC
think the mouse was actually moved.
Also see commit 0c7978c, where handling of mouse enter events was added.
This was supposed to fix certain corner cases, but they're not relevant
anymore due to changes in OSC behavior.
Commit 9777047 fixed this as well (by resetting the mouse state on
MOUSE_LEAVE), but all the behavior reverted with this commit as perhaps
a bad idea. It wasn't very robust, made it hard to distinguish real
events from artificial ones, and finally made the mouse cursor more
often visible than needed. (Now switching between workspaces doesn't
make the cursor visible again when switching to a fullscreened mpv.)
vo_x11 had a clever trick to implement a video equalizer: it requested a
DirectColor visual. This is a X11 mechanism which allows you to specify
a lookup table for each color channel. Effectively, this is a safe
override for the graphic card's gamma ramp. If X thinks the window
deserves priority over other windows in the system, X would temporarily
switch the gamma ramp so that DirectColor visuals can be displayed as
the application intends. (I'm not sure what the exact policy is, but in
practice, this meant the equalizer worked when the mouse button was
inside the window.)
But all in all, this is just lots of useless code for a feature that is
rarely ever useful. Remove it and use the libswscale equalizer instead.
(This comes without a cost, since vo_x11 already uses libswscale.)
One worry was that using DirectColor could have made it work better in
8-bit paletted mode. But this is not the case: there's no difference,
and in both cases, the video looks equally bad.
Normally, we need this for Xutf8LookupString(). But we can just fall
back to XLookupString(). In fact, the code for this was already there,
the code was just never tested and was actually crashing when active
(see commit 2115c4a).
XOpenIM can fail to find a valid input method, in which case it
returns NULL. Passing a NULL pointer to XCreateIC would cause a
crash, so fail VO init before that happens.
This is supposed to reduce the amount of useless error messages shown
during initialization of vo_opengl. If multiple backends are compiled,
usually only one of them will work. For example, on Linux both X and
Wayland backends can be compiled, but usually either Wayland or X is
running. Then, if Wayland is not running, but X is, trying to initialize
the Wayland backend should not spam the terminal with error messages.

icon_size is the number of array items of type long, not bytes. Change
the type of icon_size to int, because size_t makes you think of byte
quantities too quickly.
As an unrelated change, change the (char *) cast to (unsigned char *),
because it matches the common XChangeProperty idiom better.
The png file added to etc/ are taken from the link mentioned in commit
303096b, except that they have been converted to 16 bit, sRGB (with
color profile info dropped, if there was one), and transparent pixels
reset for better compression.
The file x11_icon.bin is generated by gen-x11-icon.sh. I'm adding it to
the git repo directly, because the script requires ImageMagick, and we
don't want to make building even more complicated.
The way how this is done is basically a compromise between effort
required in x11_common.c and in gen-x11-icon.sh. Ideally, x11_icon.bin
would be directly in the format as required by _NET_WM_ICON, but trying
to write the binary width/height values from shell would probably be a
nightmare, so here we go.
The zlib code in x11_common.c is lifted from demux_mkv.c, with some
modifications (like accepting a gzip header, because I don't know how to
make gzip write raw compressed data).
If the mpv window is unfocus, clicking on the OSC should focus the
window (done by the window manager) and allow interaction with the OSC.
But somehow X sends a spurious LeaveNotify event, immediately followed
by an EnterNotify event. This happens at least with IceWM. The result is
that the OSC will disappear (due to receiving MOUSE_LEAVE). The OSC will
stay invisible, because EnterNotify isn't handled, and there's nothing
that could make the OSC appear again.
Solve this by handling EnterNotify. We cause a redundant MOUSE_MOVE
event to be sent, which triggers the code to make the OSC visible. We
have to remove the code from input.c, which ignores redundant mouse move
events.
Since the code ignoring redundant mouse move events is still needed on
Windows, move that code to w32_common.c. The need for this is documented
in the code, also see commit 03fd2fe. (The original idea was to save
some code by having this code in the core, but now it turns out that
this didn't quite work out.)
These keys can be found on various "multimedia" and "internet" keyboard.
X defines many keycodes, so I'm not adding all, just what I found on my
own keyboard.
Other key codes can be added on request.
Disable the hack by default, because it's interfering with some more
modern WMs. MWM (Motif Window Manager) is probably pretty dead, but
we still allow enabling the old hack with "--fstype=mwm_hack".
See github issue #179.
There was a MPOpts fullscreen field, a mp_vo_opts.fs field, and
VOFLAG_FULLSCREEN. Remove all these and introduce a
mp_vo_opts.fullscreen flag instead.
When VOs receive VOCTRL_FULLSCREEN, they are supposed to set the
current fullscreen mode to the state in mp_vo_opts.fullscreen. They
also should do this implicitly on config().
VOs which are capable of doing so can update the mp_vo_opts.fullscreen
if the actual fullscreen mode changes (e.g. if the user uses the
window manager controls). If fullscreen mode switching fails, they
can also set mp_vo_opts.fullscreen to the actual state.
Note that the X11 backend does almost none of this, and it has a
private fs flag to store the fullscreen flag, instead of getting it
from the WM. (Possibly because it has to deal with broken WMs.)
The fullscreen option has to be checked on config() to deal with
the -fs option, especially with something like:
mpv --fs file1.mkv --{ --no-fs file2.mkv --}
(It should start in fullscreen mode, but go to windowed mode when
playing file2.mkv.)

Making key up events implicit was sort-of a nice idea, but it's too
tricky and unreliable and makes the key lookup code (interpret_keys())
hard to reason about. See e.g. previous commit for subtle bugs and
issues this caused.
Make key-up events explicit instead. Add key up events to all VOs.
Any time MP_KEY_STATE_DOWN is used, the matching key up event must
use MP_KEY_STATE_UP.
Rewrite the key lookup code. It should be simpler and more robust now.
(Even though the LOC increases, because the new code is less "compact".)
Also, implement mouse leave events for X11. But evne on other
platforms, these events will be generated if mouse crosses a section's
mouse area boundaries within the mpv window.
Instead of implicitly changing the window title on config(), do it as
part of the new VOCTRL.
At first I wanted to make all VOs use the VOCTRL argument directly, but
on a second thought it appears vo_get_window_title() is much more useful
for some (namely, if the window is created lazily on first config()).
Not all VOs are changed. Wayland and OSX have to follow.
Use the recently introduced screensaver VOCTRLs to control the
screensaver in the X11 backend. This means the behavior when paused
changes: the old code always kept the screensaver disabled, but now the
screensaver is reenabled on pausing.
Rename the --stop-xscreensaver option to --stop-screensaver and make it
more generic. Now it affects all backends that respond to the
screensaver VOCTRLs.
GetTimer() is generally replaced with mp_time_us(). Both calls return
microseconds, but the latter uses int64_t, us defined to never wrap,
and never returns 0 or negative values.
GetTimerMS() has no direct replacement. Instead the other functions are
used.
For some code, switch to mp_time_sec(), which returns the time as double
float value in seconds. The returned time is offset to program start
time, so there is enough precision left to deliver microsecond
resolution for at least 100 years. Unless it's casted to a float
(or the CPU reduces precision), which is why we still use mp_time_us()
out of paranoia in places where precision is clearly needed.
Always switch to the correct time. The whole point of the new timer
calls is that they don't wrap, and storing microseconds in unsigned int
variables would negate this.
In some cases, remove wrap-around handling for time values.
Instead of having separate callbacks for each backend-handled feature
(like MPGLContext.fullscreen, MPGLContext.border, etc.), pass the
VOCTRL responsible for this directly to the backend. This allows
removing a bunch of callbacks, that currently must be set even for
optional/lesser features (like VOCTRL_BORDER).
This requires changes to all VOs using gl_common, as well as all
backends that support gl_common.
Also introduce VOCTRL_CHECK_EVENTS. vo.check_events is now optional.
VO backends can use VOCTRL_CHECK_EVENTS instead to implementing
check_events. This has the advantage that the event handling code in
VOs doesn't have to be duplicated if vo_control() is used.
Block X11's native key repeat, and use mpv's key repeat handling in
input.c instead.
No configure check for XKB. Even though it's an extension, it has been
part of most (all?) xlibs since 1996. If XKB appears to be missing,
just refuse enabling x11.
This is a potentially controversial change. mpv will use its own key
repeat rate, instead of X11's. This should be better, because seeking
will have a standardized "speed" (seek events per seconds when keeping
a seek key held down). It will also allow disabling key repears for
certain commands, though this is not done anywhere yet.
The new behavior can be disabled with the --native-keyrepeat option.
The vo_x11_clearwindow_part() function assumed that the video is always
centered. Replace it with a new vo_x11_clear_background() function
instead, which essentially does the same as the old function. It takes
the video rectangle instead of just the video size, and doesn't have to
make the assumption that the video rectangle is centered.
Also make vo_x11 use it (seems advantageous).
Separate the video output options from the big MPOpts structure and also only
pass the new mp_vo_opts structure to the vo backend.
Move video_driver_list into mp_vo_opts
Removes almost every global variabel in vo.h and puts them in a special struct
in MPOpts for video output related options.
Also we completly remove the options/globals pts and refresh rate because
they were unused.
When paused, --cursor-autohide worked with a precision of 500ms, which
is the main loop's default sleep time when paused. Cursor hiding is
polled in x11_common, and the main loop never called the X11 code at
the right time. Fix this by allowing the VO to set a time when it
should be called next.
vo_opengl creates an invisible window with VOFLAG_HIDDEN in order to
test whether the OpenGL context is useable. The visible window is
created at a later point. This has been broken forever (in vo_gl,
now called vo_opengl_old, it could be avoided by disabling auto-
detection explicitly using the "yuv" sub-option). Avoiding
VOFLAG_HIDDEN only mitigates the issue, and a related bug can still
happen with some window managers (see below).
As a hack, code was added to vo_gl to destroy the (hidden) window so
that all state was destroyed. Later, more hacks were added to deal with
some caveats that came with recreating the window, such as probing for
the context up to 4 times.
Attempt to fix the problem properly. There were two problems: first,
the window was not resized to video size before mapping. This was the
main cause for the placement issue, e.g. mapping the window as 320x200,
and then resizing it. Second, mpv tried to force the window position
with XSetWMNormalHints and PPosition with values it just read with
XGetGeometry. This messes up the window manager's default placement.
It seems to be a race condition, and behavior is different across
various WMs too: with IceWM, the window manager's placement is usually
preferred, and with Fluxbox, mpv's position is preferred. mpv's default
position is centering the window on the screen, which is much nicer for
video in general than typical WM default placement, so it's possible
that this bug was perceived as a feature. (Users who want this have to
use --geometry="50%:50%", doing this by default is probably not safe
with all WMs.)
Since the old code was hard to follow and full of issues, it's easier
to redo it. Move general window creation stuff out of the
vo_x11_config_vo_window function, and move the resize logic into it.
This has been tested on IcwWM, Fluxbox, awesome, Unity/Compiz.
Store the window state (position and size) in vo_x11_state, instead of
in vo->dx/dy/dwidth/dheight. The VO variables are overwritten by vo.c on
every vo_config() call, which is extremely not helpful.
Now vo->dx/dy are mostly unused (except for passing the position forced
by the --geometry option), and vo->dwidth/dheight are set for the VO,
and otherwise read for resize detection only.
In the long term, the way vo_config() handles the --geometry option
should be changed, and vo->dx/dy should be removed.
Remove some useless stuff: VO_EVENT_MOVE and VO_EVENT_KEYPRESS were
generated, but unused. Wayland changes by Alexander Preisinger.
This allowed making the player switch the monitor video mode when
creating the video window. This was a questionable feature, and with
today's LCD screens certainly not useful anymore. Switching to a random
video mode (going by video width/height) doesn't sound too useful
either.
I'm not sure about the win32 implementation, but the X part had several
bugs. Even in mplayer-svn (where x11_common.c hasn't been receiving any
larger changes for a long time), this code is buggy and doesn't do the
right thing anyway. (And what the hell _did_ it do when using multiple
physical monitors?)
If you really want this, write a shell script that calls xrandr before
and after calling mpv.
vo_sdl still can do mode switching, because SDL has native support for
it, and using it is trivial. Add a new sub-option for this.
The --wid switch (for embedding the player into other applications)
didn't create a new window, and instead tried to use the window that
was passed via --wid directly. This made the code more complex, caused
strange X errors (mpv and host application fighting for exclusive X
resources), and actually could cause issues if the --wid window wasn't
created with the X Visual needed for OpenGL.
Always create a window instead. This makes it always possible to embed
the player into foreign windows. --geometry doesn't work anymore - the
controlling application should always create a new window to place the
player inside it, and can control the video window by moving and
resizing this window.
w32_common.c actually did this right, and always creates a new window.
