I never liked that these used integer indexes. -remove should have
existed from the start. This deprecation is yet another empty threat,
though.
|
| |
|
|
|
|
| |
Actually I wanted this for key/value lists only, but add it to the
others for consistency too. (For vf/af it barely makes even sense, but
anyway.)

Whenever I deal with this, I have to look at the code to make sense of
this. And beyond that, there are some strange inconsistencies. (I think
this code is cursed. It always was, and maybe always will be.)
Although the manpage claimed that using multiple items for -add etc. is
deprecated, string list options didn't warn against it. So add the
warning, and add something in the changelog (even though nobody will
ever read this).
The manpage mentioned --vf-append, but this didn't even exist. So add
it, I guess. We encourage using -append for the other option types, so
for consistency, it should work on filter options. (And I already
tricked me into believing it existed when I mentioned it in the
manpage.)
Make the "operations" table separate for all option types, and mention
the option type on every single of the top-level list options.

Pretty annoying affair. The vo_gpu code could of course not trigger
rendering from filters yet, so it needed to be extended. Also, this uses
some icky stuff made for vf_sub (and this was the reason I marked vf_sub
as deprecated), so everything is terrible.

Probably pretty useless in this form (see: the wall of warnings), but
someone wanted this.
I think this should be useful to perform some automated tests, maybe.

Form some reason (and because of my fault), vf_format converts image
formats, but nothing else. For example, setting the "colormatrix"
sub-parameter would not convert it to the new value, but instead
overwrite the metadata (basically "reinterpreting" the image data
without changing it).
Make the historical mistake worse, and go all the way and extend it such
that it can perform a conversion. For compatibility reasons, this needs
to be requested explicitly. (Maybe this would deserve a separate filter
to begin with, but things are messed up anyway. Feel free to suggest an
elegant and simple solution.)
This demonstrates how zimg can properly perform some conversions which
swscale cannot (see examples added to vf.rst).
Stupidly this requires 2 code paths, one for conversion, and one for
overriding the parameters.
Due to the filter bullshit (what was I thinking), this requires quite
some acrobatics that would not be necessary without these abstractions.
On the other hand, it'd definitely be more of a mess without it. Oh
whatever.

skip-logo.lua is just what I wanted to have. Explanations are on the top
of that file. As usual, all documentation threatens to remove this stuff
all the time, since this stuff is just for me, and unlike a normal user
I can afford the luxuary of hacking the shit directly into the player.
vf_fingerprint is needed to support this script. It needs to scale down
video frames as part of its operation. For that, it uses zimg. zimg is
much faster than libswscale and generates more correct output. (The
filter includes a runtime fallback, but it doesn't even work because
libswscale fucks up and can't do YUV->Gray with range adjustment.)
Note on the algorithm: seems almost too simple, but was suggested to me.
It seems to be pretty effective, although long time experience with
false positives is missing. At first I wanted to use dHash [1][2], which
is also pretty simple and effective, but might actually be worse than
the implemented mechanism. dHash has the advantage that the fingerprint
is smaller. But exact matching is too unreliable, and you'd still need
to determine the number of different bits for fuzzier comparison. So
there wasn't really a reason to use it.

I once created this because someone wanted to use vapoursynth without
the Python dependency. No idea if anyone ever actually used it. It's
sort of icky (it calls itself "lazy" to preempt complaints about how
much it sucks), and complicates the build process. Kill it.
It seems much more promising to have something like this:
https://github.com/vapoursynth/vapoursynth/issues/386
This would either solve the build distribution problem by relaxing the
Python dependency, and/or allow a Lua backend to be included without
pain.

I assume (but cannot confirm) that VA-AP-API is in fact a typo, because
most if not all search engine results related to it are from mpv's manual
page.
By changing this to VA-API and clarifying that this requires VA-API support
on a system to use it, we can hopefully make it clear to unsuspecting
Windows users that this is not the filter they're looking for.
Concerns #6690.

An exclamation mark disables the filter by default instead of
enabling it.

|
|

This switches the default away from "bob" to the best algorithm reported
as supported by the driver. This is convenient for users, and there is
no reason to use something worse by default.
Untested.

Before this, we made deinterlacing dependent on the video codec metadata
(AVFrame.interlaced_frame for libavcodec). So even if --deinterlace=yes
was set, we skipped deinterlacing if the flag wasn't set. This is very
unreliable and there are many streams with flags incorrectly set.
The potential problem is that this might upset people who alwase enabled
deinterlace and hoped it worked. But it's likely these people were
screwed by this setting anyway. The new behavior is less tricky and
easier to understand, and this preferable. Maybe one day we could
introduce a --deinterlace=auto, which does the right thing, but of
course this would be hard to implement (esecially with hwdec).
Fixes #5219.

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.

It has been deprecated for a while and is 100% useless. It was forgotten
in the recent filter purge. Get rid of it.

Almost all of them had their guts removed and replaced by libavfilter
long ago, but remove them anyway. They're pointless and have been
scheduled for deprecation.
Still leave vf_format (because we need it in some form) and vf_sub (not
sure).
This will break some builtin functionality: lavfi yadif defaults are
different, auto rotation and stereo3d downconversion are broken. These
might be fixed later.

Both the video equalizer command/option glue, which drives this filter,
as well as the filter itself are slightly GPL contaminated. So it goes.
After this commit, "--vf=eq" will actually use libavfilter's vf_eq (if
FFmpeg was compiled in GPL mode), but it has different options and will
not listen to the equalizer VOCTRLs.
|

|

Also use lavfi setfield instead of removed field-dominance.
Remove missing remainder of field-dominance in docs.

This adds handling of spherical video metadata: retrieving it from
demux_lavf and demux_mkv, passing it through filters, and adjusting it
with vf_format. This does not include support for rendering this type of
video.
We don't expect we need/want to support the other projection types like
cube maps, so we don't include that for now. They can be added later as
needed.
Also raise the maximum sizes of stringified image params, since they
can get really long.

Apparently this is virtually identical to Panasonic's V-Log, but using
the constants from S-Log1 and an extra scaling coefficient to make the
S-Log1 curve less limited. Whatever floats their NIH boat, I guess.

Not 100% confident in the implementation since the values from the spec
seem to be very subtly off (~1%), but it should be close enough for
practical purposes.

This introduces (yet another..) mp_colorspace members, an enum `light`
(for lack of a better name) which basically tells us whether we're
dealing with scene-referred or display-referred light, but also a bit
more metadata (in which way is the scene-referred light expected to be
mapped to the display?).
The addition of this parameter accomplishes two goals:
1. Allows us to actually support HLG more-or-less correctly[1]
2. Allows people playing back direct “camera” content (e.g. v-log or
s-log2) to treat it as scene-referred instead of display-referred
[1] Even better would be to use the display-referred OOTF instead of the
idealized OOTF, but this would require either native HLG support in
LittleCMS (unlikely) or more communication between lcms.c and
video_shaders.c than I'm remotely comfortable with
That being said, in principle we could switch our usage of the BT.1886
EOTF to the BT.709 OETF instead and treat BT.709 content as being
scene-referred under application of the 709+1886 OOTF; which moves that
particular conversion from the 3dlut to the shader code; but also allows
a) users like UliZappe to turn it off and b) supporting the full HLG
OOTF in the same framework. But I think I prefer things as they are
right now.

st2084 and std-b67 are really weird names for PQ and HLG, which is what
everybody else (including e.g. the ITU-R) calls them. Follow their
example.
I decided against naming them bt2020-pq and bt2020-hlg because it's not
necessary in this case. The standard name is only used for the other
colorspaces etc. because those literally have no other names.

List of changes:
1. Kill nom_peak, since it's a pointless non-field that stores nothing
of value and is _always_ derived from ref_white anyway.
2. Kill ref_white/--target-brightness, because the only case it really
existed for (PQ) actually doesn't need to be this general: According
to ITU-R BT.2100, PQ *always* assumes a reference monitor with a
white point of 100 cd/m².
3. Improve documentation and comments surrounding this stuff.
4. Clean up some of the code in general. Move stuff where it belongs.

It was an attempt to move some MPlayer filters (which were removed from
mpv) to external, loadable filters. That worked well, but then the
MPlayer filters were ported to libavfilter (independently), so they're
available again. Also there is a more widely supported and more advanced
loadable filter system supported by mpv: vapoursynth.
In conclusion, vf_dlopen is not useful anymore, confusing, and requires
quite a bit of code (and probably wouldn't survive the rewrite of the
mpv video filter chain, which has to come at some point). It has some
implicit dependencies on internal conventions, like possibly the format
names dropped in the previous commit.
We also deprecated it last release. Drop it.
|
| |
|
|
|
|
| |
Add the "lavfi-" prefix (details see manpage additons).
Tag the filter name as "(lavfi)" in the verbose filter list output.
|
| |
|
|
|
|
| |
Now e.g. --vf=pad=1000:1000 works.
All in all pretty ugly and hacky. Just look away.
|
| |
|
|
|
|
|
|
|
|
| |
Now you can for example do "--vf=hue=h=60" - there is no "hue" filter in
mpv, so libavfilter's will be used.
This has certain caveats (see manpage).
The point of this is providing a relatively smooth transition path to
removing our own filter stuff.

The plan is to nuke the custom filter chain completely. It's not clear
what will happen to the still needed builtin filters (mostly hardware
deinterlacing and vf_vapoursynth). Most likely we'll replace them with
different filter chain concept (whose main purpose will be providing
builtin things and bridging to libavfilter).
The undocumented "warn" options are there to disable deprecation
warnings when the player inserts filter automatically.
The same will be done to audio filters, at a later point.

"@name:!" becomes simply "@name". This is actually slightly more complex
to parse, but makes for a much simpler syntax and will be less weird to
the user. Suggested by haasn.
The old syntax is now rejected with an error.
Also add some more explicit error checks, instead of e.g. allowing empty
filter names and erroring only when it's not found.

Basically, see the example in input.rst.
This is better than the "old" vf-toggle method, because it doesn't
require the user to duplicate the filter string in mpv.conf and
input.conf.
Some aspects of this changes are untested, so enjoy your alpha testing.

this.

I'm not sure what's going on here, but it appears kodi switches forward
and backwards references for advanced VPP deinterlacing modes. This in
turn makes deinterlacing with these modes apparently work. If you don't
switch the directions, you get a stuttering mess.
As far as the libva trace dump is concerned, this makes mpv's libva
deinterlacing API use behave like kodi's, and appears to reproduce
smooth video with advanced libva deinterlacing enabled.
I'm hearing that Mesa actually does it correctly, and I'm not sure what
will happen there. For now, passing "reversal-bug=no" as sub-option to
the vavpp filter will undo this behavior.

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.
Mind: This encoding uses full range values, not TV range.

This is actually not entirely trivial since it involves negative Yxy
coordinates, so the CMM has to be capable of full floating point
operation. Fortunately, LittleCMS is, so we can just blindly implement
it.

This HDR function is unique in that it's still display-referred, it just
