This parameter has been unused for years (the last flag was removed in
commit d658b115). Get rid of it.
This affects the general VO API, as well as the vo_opengl backend API,
so it touches a lot of files.
The VOFLAGs are still used to control OpenGL context creation, so move
them to the OpenGL backend code.
|
|
|
|
|

Get it out of the way in the common code. MPGLContext.dwm_flush_opt can
be removed as well as soon as the option system gets overhauled.

You needed to select a GL backend with the backend suboption. This was
confusing.

This is a bit redundant with the name of the directory itself, and not
in line with existing naming conventions.

This is mainly just to keep things a bit more organized and separated

This might fix some problems when framestepping with interpolation
enabled. The problem here is that we want to show the non-interpolated
frame while paused. Framestepping is like unpausing the video for a
frame, and then pausing again. This draws an interpolated frame, and
redrawing on pausing is supposed to take care of this.
This possibly didn't always work, because vo->want_redraw is not checked
by the vo_control() code path. So wake up the VO thread (which takes
care of servicing redraw requests, kind of) explicitly.
The correct solution is getting rid of the public-writable want_redraw
field and replacing it with a new vo_request_redraw() function, but this
can come later.

Just avoid some code duplication. Also, gl_video_set_options() having a
queue size output parameter is weird at best. While I don't appreciate
that this commit suddenly requires gl_video.c to deal with vo.c directly
in a special case, it's simply the best place to put this function.

See manpage additions. This is mainly useful for vo_opengl_cb, but can
also be applied to vo_opengl.
On a side note, gl_hwdec_load_api() should stop using a name string, and
instead always use the IDs. This should be cleaned up another time.

draw_image_timed is renamed to draw_frame. struct frame_timing is
renamed to vo_frame. flip_page_timed is merged into draw_frame (the
additional parameters are part of struct vo_frame). draw_frame also
deprecates VOCTRL_REDRAW_FRAME, and replaces it with a method that
works for both VOs which can cache the current frame, and VOs which
need to redraw it anyway.
This is preparation to making the interpolation and (work in progress)
display sync code saner.
Lots of other refactoring, and also some simplifications.

This should make interpolation work much better in general, although
there still might be some side effects for unusual framerates (eg. 35 Hz
or 48 Hz). Most of the common framerates are tested and working fine.
(24 Hz, 30 Hz, 60 Hz)
The new code doesn't have support for oversample yet, so it's been
removed (and will most likely be reimplemented in a cleaner way if
there's enough demand). I would recommend using something like robidoux
or mitchell instead of oversample, though - they're much
smoother for the common cases.

Now the VO can request a number of future frames with the last parameter
of vo_set_queue_params(). This will be helpful to fix the interpolation
code.
Note that the first frame (after playback start or seeking) will usually
not have any future frames (to make seeking fast). Near the end of the
file, the number of future frames will become lower as well.

An attempt to get rid of the weird mix of callbacks that take either
struct vo or MPGLCopntext as parameter. This is not perfect, and the
API will probably change a bit until all other code is ported to it.
the main question is how to separate struct vo completely from the
windowing code, which actually needs vo for very little.
In the end, the legacy callbacks will be dropped.

Instead of having separate backends, make use of GLES a flag. This
reduces the number of backends and the resulting annoyances.
Also, nobody cares about using GLES, so there's no backward
compatibility either.

This will essentially make screenshot-tag-colorspace also affect the
"screenshot window" command, where possible.
Unfortunately, it's completely incompatible with icc-profile, due to API
limitations of ffmpeg (we can only give it an enum of well-known
primaries, rather than an actual ICC profile or primaries).

I think this used to be quite important, because the ancient VfW support
in MPlayer used to output flipped frames. This code has been dead in mpv
for quite some time (because VfW decoders were removed, and the --flip
option was dropped too), so get rid of it.

Currently, the wayland backend needs extra work to avoid drawing more
often than the wayland frame callback allows. (This is not ideal, but
will be fixed at a later time.)
Unify this with the start_frame callback added for cocoa. Some details
change for the better. For example, if a frame is dropped, and a redraw
is done afterwards, the actually correct frame is redrawn, instead
whatever was in the textures from before the dropped frame.

With --idle --force-window, or when started from the bundle, the cocoa
code dropped the first frame. This resulted in a black frame on start
sometimes.
The reason was that the live resizing/redrawing code was invoked, which
simply set skip_swap_buffer to false, blocking redrawing whatever was
going to be rendered next. Normally this is done so that the following
works:
1. vo_opengl draw a frame, releases GL lock
2. live resizing kicks in, redraw the frame
3. vo_opengl wants to call SwapBuffers, drawing a stale buffer
overwritten by the live resizing code
This is solved by setting skip_swap_buffer in 2., and querying it in 3.
Fix this by resetting the skip_swap_buffer at a known good point: when
vo_opengl starts drawing a new frame.
The start_frame function returns bool, so that it can be merged with
is_active in a following commit.

Use a choice instead of an integer. This is incompatible, but I'm not
adding any compatibility since this option was added recently.

This could help in cases where the DWM (Windows desktop compositor) adds another
layer of bufferring and therefore the SwapBuffers timing could get messed up.

Rarely used and essentially useless. The only VO for which this was
implemented correctly and for which this did anything was vo_xv, but you
shouldn't use vo_xv anyway (plus it support BT.601 only, plus a vendor
specific extension for BT.709, whose presence this function essentially
reported - use xvinfo instead).

Instead of somehow looking for the substring "_swap_control" and trying
to several arbitrary function names, do it cleanly. The old approach has
the problem that it's not very exact, and may even load a pointer to a
function which doesn't exist. (Some GL implementations like Mesa return
function pointers even the functions which don't exist, and calling them
crashes.)
I couldn't find any evidence that glXSwapInterval, wglSwapIntervalSGI,
or wglSwapInterval actually exist, so don't include them. They were
carried over from MPlayer times.
To make diagnostics easier, print a warning in verbose mode if the
function could not be loaded.

When not receiving frame callbacks, we should not draw anything to avoid
blocking the OpenGL renderer. We do this by extending gl context api, by
introducing new optional function 'is_active', that indicates whether
OpenGL renderers should draw or not.
This fixes issue #249.

Unlike other VOs, this rendered OSD even while no VO was created
(because the renderer lives as long as the API user wants). Change this,
and refactor the code so that the OSD object is accessible only while
the VO is created.
(There is a short time where the OSD can still be accessed even after VO
destruction - this is not a race condition, though it's inelegant and
unfortunately unavoidable.)

There's literally no reason why these functions have to be inline (they
might be performance critical, but then the function call overhead isn't
going to matter at all).
Uninline them and move them to mp_image.c. Drop the header file and fix
all uses of it.

This replaces the old smoothmotion code by a more flexible tscale
option, which essentially allows any scaler to be used for interpolating
frames. (The actual "smoothmotion" scaler which behaves identical to the
old code does not currently exist, but it will be re-added in a later commit)
The only odd thing is that larger filters require a larger queue size
offset, which is currently set dynamically as it introduces some issues
when pausing or framestepping. Filters with a lower radius are not
affected as much, so this is identical to the old smoothmotion if the
smoothmotion interpolator is used.

The basic idea is to use dynamically generated shaders instead of a
single monolithic file + a ton of ifdefs. Instead of having to setup
every aspect of it separately (like compiling shaders, setting uniforms,
perfoming the actual rendering steps, the GLSL parts), we generate the
GLSL on the fly, and perform the rendering at the same time. The GLSL
is regenerated every frame, but the actual compiled OpenGL-level shaders
are cached, which makes it fast again. Almost all logic can be in a
single place.
The new code is significantly more flexible, which allows us to improve
the code clarity, performance and add more features easily.
This commit is incomplete. It drops almost all previous code, and
readds only the most important things (some of them actually buggy).
The next commit will complete it - it's separate to preserve authorship
information.

mpv would attempt to load ICC profiles several times during VO init
even if no window is displayed. This potentially causes it to load
a profile for a different screen than it is going to be displayed
on, thereby invalidating the profile cache and rebuilding the LUT
every single time.
It would not unload a previously loaded profile when the video
window is moved to a display without an installed profile.
Fix these issues and tweak the log messages a little.

This automatically sets the gamma option depending on lighting conditions
measured from the computer's ambient light sensor.
sRGB – arguably the “sibling” to BT.709 for still images – has a reference
viewing environment defined in its specification (IEC 61966-2-1:1999, see
http://www.color.org/chardata/rgb/srgb.xalter). According to this data, the
assumed ambient illuminance is 64 lux. This is the illuminance where the gamma
that results from ICC color management is correct.
On the other hand, BT.1886 formalizes that the gamma level for dim environments
to be 2.40, and Apple resources (WWDC12: 2012 Session 523: Best practices for
color management) define the BT.1886 dim at 16 lux.
So the logic we apply is:
* >= 64lux -> 1.961 gamma
* =< 16lux -> 2.400 gamma
* 16lux < x < 64lux -> logaritmic rescale of lux to gamma. The human
perception of illuminance roughly follows a logaritmic scale of lux [1].

If smoothmotion is enabled, and the screen shows an interpolated frame
the moment you pause, redraw a non-interpolated frame.

gl_common.c contained the function loader (which is big) and additional
utility functions (not so big, but will grow when moving more out of
gl_video.c). Just split them. There are no changes other than some

Merge update_icc_profile() into get_and_update_icc_profile() - there's
no reason anymore to keep them separate. The former is only called by
the latter, and the separation of responsibilities between them is
blurry a best.
Query the ICC profile only if the corresponding feature is actually
enabled. Additionally, change the error behavior of this code. Make
loading failure non-fatal, and distinguish between runtime error and
unimplemented functionality.
Fix a memory leak in gl_lcms.c (although the changes in vo_opengl.c
already take care of this, it's just logical and cleaner).

At the time screenshot support was added, images weren't refcounted yet,
so screenshots required specialized implementations in the VOs. But now
we can handle these things much simpler. Also see commit 5bb24980.
If there are VOs in the future which can't do this (e.g. they need to
write to the image passed to vo_driver->draw_image), this still could be
disabled on a per-VO basis etc., so we lose no potential performance
advantages.

Use different VOCTRLs for "window" and normal screenshot modes. The
normal one will probably be removed, and replaced by generic code in
vo.c, and this commit is preparation for this. (Doing it the other way
around would be slightly simpler, but I haven't decided yet about the
second one, and touching every VO is needed anyway in order to remove
the unneeded crap. E.g. has_osd has been unused for a long time.)

vo.c queried the VO at initialization whether it wants to be updated on
every display frame, or every video frame. If the smoothmotion option
was changed at runtime, the rendering mode in vo.c wasn't updated.
Just let vo_opengl set the mode directly. Abuse the existing
vo_set_flip_queue_offset() function for this.
Also add a comment suggesting the use of --display-fps to the manpage,
which doesn't have anything to do with the rest of this commit, but is
important to make smoothmotion run well.

SmoothMotion is a way to time and blend frames made popular by MadVR. It's
intended behaviour is to remove stuttering caused by mismatches between the
display refresh rate and the video fps, while preserving the video's original
artistic qualities (no soap opera effect). It's supposed to make 24fps video
playback on 60hz monitors as close as possible to a 24hz monitor.
Instead of drawing a frame once once it's pts has passed the vsync time, we
redraw at the display refresh rate, and if we detect the vsync is between two
frames we interpolated them (depending on their position relative to the vsync).
We actually interpolate as few frames as possible to avoid a blur effect as
much as possible. For example, if we were to play back a 1fps video on a 60hz
monitor, we would blend at most on 1 vsync for each frame (while the other 59
vsyncs would be rendered as is).
Frame interpolation is always done before scaling and in linear light when
possible (an ICC profile is used, or :srgb is used).

Before this commit, each hw backend had their own specific struct types
for context, and some, like VDA, had none at all. Add a context struct
(mp_hwdec_ctx) that provides a somewhat generic way to pass the hwdec
context around. Some things get slightly better, some slightly more
verbose.
mp_hwdec_info is still around; it's still needed, but is reduced to its
role of handling delayed loading of the hwdec backend.

And remove all uses of the VFCAP_CSP_SUPPORTED* constants. This is
supposed to reduce conversions if many filters are used (with many
incompatible pixel formats), and also for preferring the VO's natively
supported pixel formats (as opposed to conversion).
This is worthless by now. Not only do the main VOs not use software
conversion, but also the way vf_lavfi and libavfilter work mostly break
the way the old MPlayer mechanism worked. Other important filters like
vf_vapoursynth do not support "proper" format negotation either.
Part of this was already removed with the vf_scale cleanup from today.
While I'm touching every single VO, also fix the query_format argument
(it's not a FourCC anymore).

Don't load all the legacy functions (including ancient extensions).
Slightly simplify function loader and context creation, now that legacy
GL doesn't need to be handled. Remove the code for drawing OSD in legacy
mode.
Remove all the header hacks, which were meant for ancient OpenGL headers
which didn't even support things like OpenGL 1.3. Instead, adjust the
GLX check to make sure we get both OpenGL 3x and 2.1 symbols. For win32
and OSX, we assume that the user has the latest headers anyway. For
wayland, we hope that things somehow go right.

vo_opengl was crashing since f811348d because it passed NULL for the
events parameter to vo_control. Normally the parameter should not be
NULL, so add a hack to account for this. In particular, we should
handle the events that are returned. For the call in preinit() we
skip this, but it most likely has no meaning anyway, because in this
stage no window is visible yet.

This affects OSX, where memory profiles are updated e.g. on fullscreen
switches. The profile most likely doesn't change, but the LUT will
be generated and reloaded anyway.

Previously we just forced loading a profile from file, but that has poor
integration for querying the OS / display server for an ICC profile, and
generating profiles on the fly (which we might use in the future for creating
preset 3dluts).
Also changed the previous icc-profile-auto code to use this mechanism, and
moved gl_lcms to be an opaque type with state instead of just providing pure
functions.
