The intention was that if --blend-subtitles is enabled, the frame should
always be re-rendered instead of using e.g. a cached scaled frame. The
reason is that subtitles can change anyway, e.g. if you pause and change
subtitle size and such.
On the other hand, if the frame is marked as repeated, it should always
use the cached copy. Actually "simplify" this and drop the cache only if
playback is paused (which frame->still indicates indirectly).
Also see PR #3773.

unmap_current_image() is called after rendering. This essentially
invalidates the textures, so we can't assume that the image is still
present.

This allows us to define the tukey window (and other tapered windows).
Also add a missing option definition for `wblur` while we're at it, to
make testing out window-related stuff easier.

It's not that easy to decide whether a frame needs to be
reuploaded/rerendered. Using unique frame IDs for input makes it
slightly easier and more robust. This also removes the use of video PTS
in the interpolation path.
This should also avoid reuploading the video frame if it's just redrawn
in paused mode, or when using OSD/subtitles in cover art mode.

It turns out the glFlush() call really helps in some cases, though only
in audio timing mode (where we render, then wait for a while, then
display the frame). Add a --opengl-early-flush=auto mode, which does
exactly that.
It's unclear whether this is fine on OSX (strange things going on
there), but it should be.
See #3670.

In "dumb mode" (where most features are disabled and which only performs
some basic rendering) we explicitly copy a set of whitelisted options,
and leave all the other options at their default values. Add the new
--opengl-early-flush option to this whitelist. Also remove an option
field accidentally added in the commit adding --opengl-early-flush.

It seems this can cause issues with certain platforms, so better to
disable it by default. The original reason for this isn't overly
justified, and display-sync mode should get rid of the need for it
anyway.
The new option is meant for testing, and will probably be removed if
nobody comes up and reports that enabling the option actually improves
anything.

The extra gl_transform_trans() has no apparent use.

Other than being overly convoluted, this seems to make sense to me.
Except that to get the "rot" transform I have to set flip=true, which
makes no sense at all to me.

Combining rotation and cropping didn't work. It was just completely
broken.
I'm still not sure if this is correct. Chroma positioning seems to be
broken on rotation. There might also be a problem with non-mod-2 frame
sizes. Still, strictly an improvement for both rotated and non-rotated
rendering modes.
Also, this could probably be written in a more elegant way.

When we rotate the inmage by 90° or 270°, chroma width and height need
to be swapped.
Fixes #3568.
But is the chroma sub location correct? Who the hell knows...

Extend the flag-based notification mechanism that was used via
M_OPT_TERM. Make the vo_opengl update mechanism use this (which, btw.,
also fixes compilation with OpenGL renderers forcibly disabled).
While this adds a 3rd mechanism and just seems to further the chaos, I'd
rather have a very simple mechanism now, than actually furthering the
mess by mixing old and new update mechanisms. In particular, we'll be
able to remove quite some property implementations, and replace them
with much simpler update handling. The new update mechanism can also
more easily refactored once we have a final mechanism that handles
everything in an uniform way.

There were multiple values under M_OPT_EXIT (M_OPT_EXIT-n for n>=0).
Somehow M_OPT_EXIT-n either meant error code n (with n==0 no error?), or
the number of option valus consumed (0 or 1). The latter is MPlayer
legacy, which left it to the option type parsers to determine whether an
option took a value or not. All of this was changed in mpv, by requiring
the user to use explicit syntax ("--opt=val" instead of "-opt val").
In any case, the n value wasn't even used (anymore), so rip this all
out. Now M_OPT_EXIT-1 doesn't mean anything, and could be used by a new
error code.

Negative height is used to signal a flipped framebuffer. There's
absolutely no reason to pass this down to overlay_adjust(), and only
requires implementers to deal with an additional special-case.

A minor cleanup that makes the code simpler, and guarantees that we
cleanup the GL state properly at any point.
We do this by reusing the uniform caching, and assigning each sampler
uniform its own texture unit by incrementing a counter. This has various
subtle consequences for the GL driver, which hopefully don't matter. For
example, it will bind fewer textures at a time, but also rebind them
more often.
For some reason we keep TEXUNIT_VIDEO_NUM, because it limits the number
of hook passes that can be bound at the same time.
OSD rendering is an exception: we do many passes with the same shader,
and rebinding the texture each pass. For now, this is handled in an
unclean way, and we make the shader cache reserve texture unit 0 for the
OSD texture. At a later point, we should allocate that one dynamically
too, and just pass the texture unit to the OSD rendering code. Right now
I feel like vo_rpi.c (may it rot in hell) is in the way.

The caller now has to call gl_sc_reset(), and _after_ rendering. This
way we can unset OpenGL state that was setup for rendering. This affects
the shader program, for example. The next commit uses this to
automatically manage texture units via the shader cache.
vo_rpi.c changes untested.
|
| |
|
|
|
| |
This bound video textures to individual texture units - this is how it
used to work long ago, but now is pointless, and maybe even dangerous.

The wrong enum got copied here, so it was essentially using the transfer
characteristics as the primaries (instead of the primaries), which
accidentally worked fine most of the time (since the two usually
coincided), but broke on weird/mistagged files.

This overlay support specifically skips the OpenGL rendering chain, and
uses GL rendering only for OSD/subtitles. This is for devices which
don't have performant GL support.
hwdec_rpi.c contains code ported from vo_rpi.c. vo_rpi.c is going to be
deprecated. I left in the code for uploading sw surfaces (as it might
be slightly more efficient for rendering sw decoded video), although
it's dead code for now.
|
| |
|
|
|
|
|
| |
Just another corner-caseish potential issue. Unlike unreffing the image
manually, unref_current_image() also takes care of properly unmapping
hwdec frames. (The corner-case part of this is that it's probably never
mapped at this point, but it's apparently not entirely guaranteed.)

The " || vimg->mpi" part virtually never seems to trigger, but on the
other hand could possibly create unintended corner cases (for example by
trying to upload a NULL image, which would then be marked as an error
and render a blue screen).
I guess it's a leftover from over times, where a NULL image meant
"redraw the current frame". This is now handled by actually passing
along the current frame.
|
| |
|
|
|
| |
This could also trigger in certain other cases, whenever it falls back
to dumb mode.

Instead of copying the options around... just don't. video.c now has
full control over when options are updated. (It still gets notified from
outside, but it decides when the updated options are copied: when
m_config_cache_update() is called.) So there's no need for tricky
stuff, and it can be simplified a bit.
Also change lcms.c. We could do it like video.c, and get the options
from the global config store. But it seems simpler to just provide a
pointer to an option struct, which is arbitrarily mutated from the
outside (from the perspective of lcms.c).

Setting --icc-profile had no effect, until a vo_opengl option was
changed at runtime. We must initialize the renderer for the initial
option state too.
For some reason, the ICC profile gets loaded twice. The next commit
happens to fix this.

vo_opengl sub-option were always rather annoying to handle. It seems
better to make them global options instead. This is simpler and easier
to use. The only disadvantage we are aware of is that it's not clear
that many/all of these new global options work with vo_opengl only.
--vo=opengl-hq is also deprecated.
There is extensive compatibility with the old behavior. One exception is
that --vo-defaults will not apply to opengl-hq (though with opengl it
still works). vo-cmdline is also dysfunctional and will be removed in a
following commit.
These changes also affect opengl-cb.
The update mechanism is still rather inefficient: it requires syncing
with the VO after each option change, rather than batching updates.
There's also no granularity (video.c just updates "everything", and if
auto-ICC profiles are enabled, vo_opengl.c will fetch them on each
update).
Most of the manpage changes were done by Niklas Haas <git@haasn.xyz>.

Reduce accesses to the renderer opts in vo_opengl.c, and instead add
accessors for them to video.c.
I suppose gamma and maybe icc-auto could be moved to vo_opengl.c
options. Also, the output colorspace could probably be adjusted to what
is really used, not just the options (although it's possible that this
commit changes this, due to video.c mutating its own copy of the options
according to actual renderer capapbilities).
But don't deal with this now.

Deprecated in favor of user-shaders, which are functionally equivalent
but superior. (Except in the case of scaler-shader, which has no direct
replacement, but it turned out to be a very unpopular feature either way
- most custom scalers don't fit into the mpv kernel infrastructure and
are therefore implemented as user shaders either way)

It seems like many GL implementations (including Mesa) choke on this,
while others are fine. We still think that this use of the GL API is
allowed by the standard (at least in the Mesa case), so to reduce
confusion, explicitly check the "controversial" calls, and use an
appropriate error message.

This requires changing the pixel upload alignment because the odd sizes
might not be aligned to multiples of 4.
Anyway, the restriction has no real benefit and the sizes in between 32
and 64 might be worth using, so just drop it.

This code had the exact same texture indexing bug that the original
scaler code had before the introduction of the LUT_POS macro to fix it.
We can re-use this same macro here, and the performance drop is
virtually entirely negligible. The benefit is greatly improved LUT
accuracy as the 3DLUT size decreases - in particular, the old LUT
started introducing more and more black crush the lower your LUT size is
(because the error was essentially an over-contrast bias, with a
magnitude linearly related to the lut size).
The new code improves black stability as the LUT size decreases, and
only at very low values (16 and below) do black levels start noticeably
getting affected (due to crude linearization of the nonlinear response
curve).
The default value of 3dlut-size is definitely generous enough for this
to make no difference out of the box, but it also causes no performance
drop at all on my machine so I see no harm in improving the logic.
Furthermore, this means we could easily decrease the default 3dlut size
in a future commit, perhaps even down to 64x64x64 as a default. (But
more testing is warranted here)

This uses GLSL mix() instead of going through an indirect texture
access. Easy to implement and might require less resources on some
devices, since the oversample code was already essentially just a
special case of this.
Could be made the new default (as per issue #2685), but that should be
done in a separate commit.

This can for example happen with vo_opengl_cb, if it is used with a GL
implementation that does not supports FBOs. (mpv itself should never
attempt to use FBOs if they're not available.)
Without this check it would trigger an assert() in our dummy
glBindFramebuffer wrapper.
Suspected cause of #3308, although it's still unlikely.

This moves some of the bulky user-shader specific logic into the file
dedicated to it. Rather than expose video.c state, variable lookup is
now done via a simulated closure.

This involves multiple changes:
1. Brightness metadata is split into nominal peak and signal peak.
For a quick and dirty explanation: nominal peak is the brightest value
that your color space can represent (i.e. the brightness of an encoded
1.0), and signal peak is the brightest value that actually occurs in
the video (i.e. the brightest thing that's displayed).
2. vo_opengl uses a new decision logic to figure out the right nom_peak
and sig_peak for all situations. It also does a better job of picking
the right target gamut/colorspace to use for the OSD. (Which still is
and still should be treated as sRGB). This change in logic also
fixes #3293 en passant.
3. Since it was growing rapidly, the logic for auto-guessing / inferring
the right colorimetry configuration (in pass_colormanage) was split from
the logic for actually performing the adaptation (now pass_color_map).
Right now, the new logic doesn't do a whole lot since HDR metadata is
still ignored (but not for long).

This has two reasons:
1. I tend to add new fields to this metadata, and every time I've done
so I've consistently forgotten to update all of the dozens of places in
which this colorimetry metadata might end up getting used. While most
usages don't really care about most of the metadata, sometimes the
intend was simply to “copy” the colorimetry metadata from one struct to
another. With this being inside a substruct, those lines of code can now
simply read a.color = b.color without having to care about added or
removed fields.
2. It makes the type definitions nicer for upcoming refactors.
In going through all of the usages, I also expanded a few where I felt
that omitting the “young” fields was a bug.

Commit 883d3114 seems to have (accidentally?) dropped the FBOTEX_FUZZY
from the output_fbo resize, which means that current master will keep
resizing and resizing the FBO as you change the window size, introducing
severe memory leaking after a while. (Not sure why that would cause
memory leaks, but I blame nvidia)
Either way, it's bad for performance too, so it's worth fixing.

GL generally does not support flipping the image on upload, meaning
negative strides are not supported. vo_opengl handles this by flipping
rendering if the stride is inverted, and gl_pbo_upload() "ignores"
negative strides by uploading without flipping the image.
If individual planes had strides with different signs, this broke. The
flipping affected the entire image, and only the sign of the first plane
was respected.
This is just a crazy corner case that will never happen, but it turns
out this is quite simple to support, and actually improves the code
somewhat.

This introduces a gl_pbo_upload_tex() function, which works almost like
our gl_upload_tex() glTexSubImage2D() wrapper, except it takes a struct
which caches the PBO handles. It also takes the full texture size (to
make allocating an ideal buffer size easier), and a parameter to disable
PBOs (so that the caller doesn't have to duplicate the gl_upload_tex()
call if PBOs are disabled or unavailable).
This also removes warnings and fallbacks on PBO failure. We just
silently try using PBOs on every frame, and if that fails at some point,
revert to normal texture uploads. Probably doesn't matter.

Instead of hard-coding a big list, move some of the functionality
to csputils. Affects both the auto-guess blacklist and the peak
estimation.
Also update the comments.

|
|
|

Too many "exceptions" these days, it's easier to just hard-code a
whitelist instead of a blacklist. And besides, it only really makes
sense to avoid adaptation for BT.601 specifically, since that's the one
we auto-guess based on the resolution.

I'm not even sure why we ever consulted *_src to begin with, since that
just describes the current image format - and not the original metadata.
(And in fact, we specifically had logic to work around the impliciations
this had on linear scaling)
image_params is *the* authoritative source on the intended (i.e.
reference) image metadata, whereas *_src may be changed by previous
passes already. So only consult image_params for picking auto-generated
values.
Also, add some more missing "wide gamut" and "non-gamma" curves to the
autoconfig blacklist. (Maybe it would make sense to move this list to
csputils in the future? Or perhaps even auto-detect it based on the
associated primaries)

User request and not that hard. Closes #3157.
Note that FFmpeg doesn't support this and there's no signalling in HEVC
etc., so the only way users can access it is by using vf_format
manually.

This HDR function is unique in that it's still display-referred, it just
allows for values above the reference peak (super-highlights). The
official standard doesn't actually document this very well, but the
nominal peak turns out to be exactly 12.0 - so we normalize to this
value internally in mpv. (This lets us preserve the property that the
textures are encoded in the range [0,1], preventing clipping and making
the best use of an integer texture's range)
This was grouped together with SMPTE ST2084 when checking libavutil
compatibility since they were added in the same release window, in a
similar timeframe.
