This means vf_vapoursynth doesn't need a hack to work around the filter
code, and libavfilter filters now actually get the frame_rate field on
input pads set.
The libavfilter doxygen says the frame_rate field is only to be set if
the frame rate is known to be constant, and uses the word "must" (which
probably means they really mean it?) - but ffmpeg.c sets the field to
mere guesses anyway, and it looks like this normally won't lead to
problems.

Commit 59f9547fb56b missed this case, in which we can't make new
progress and have to exit.

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.

In theory (and practice), this is not needed, because the VS filter get
frame callback will cause the process function to be called again if
there's not enough data. But it's still a bit weird to just add one more
frame on each iteration, so make it cleaner and make it request frames
until the input array is full.

This was obviously nonsense, and a previous "fix" to this code was
nonsense too. What is really needed here is temporarily dropping the
lock while calling destroy_vs()/reinit_vs().
Fixes #5470.

Unknown frames were not freed properly. Although this doesn't really
happen anyway, because we're never going to feed audio frames to a video
filter chain. Since it's theoretically possible, and all other filters
handle this consistently, fix it anyway.

|
|
|

|

Properly initialize the output frame parameters other than image format
and size. This includes colorspace hints. (We're still not reading them
back from VapourSynth if it sets them, though. Usually it doesn't
anyway.)
|
| |
|
|
|
| |
When VS initialization failed, it could hang due to forgetting to
release the mutex.
|
| |
|
|
|
|
|
|
|
| |
VapourSynth can't pass through timestamps, only frame durations. So we
need to remember the timestamp of the very first frame passed to it.
This was accidentally set to 0 instead of NOPTS on init, so inserting
the filter during playback could show strange behavior.
Might be part of #5470.

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.

mp_sws_set_from_cmdline() has the only purpose to respect the --sws-
command line options. Instead of forcing callers to get the option
struct containing these, let callers pass mpv_global, and get it from
the option core code directly. This avoids minor annoyances later on.

Remove the max_count creation parameter, because it's pointless and
rarely ever did anything. Add a talloc parent parameter instead (which
is something completely different, but convenient, and all callers needs
to be changed anyway).
Instead of clearing the pool when the now removed maximum is reached,
clear it on image parameter changes instead.

Crashed when no vdpau device was loaded. Also there was a mistake of not
setting p->ctx, which broke software surface input mode. This was not
found before, because p->ctx is not needed for anything else.

I've decided that MP_TRACE means “noisy spam per frame”, whereas
MP_DBG just means “more verbose debugging messages than MSGL_V”.
Basically, MSGL_DBG shouldn't create spam per frame like it currently
does, and MSGL_V should make sense to the end-user and provide mostly
additional informational output.
MP_DBG is basically what I want to make the new default for --log-file,
so the cut-off point for MP_DBG is if we probably want to know if for
debugging purposes but the user most likely doesn't care about on the
terminal.
Also, the debug callbacks for libass and ffmpeg got bumped in their
verbosity levels slightly, because being external components they're a
bit less relevant to mpv debugging, and a bit too over-eager in what
they consider to be relevant information.
I exclusively used the "try it on my machine and remove messages from
MSGL_* until it does what I want it to" approach of refactoring, so
YMMV.

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

Full range YUV causes problems everywhere. For example it's usually the
wrong choice when using encoding mode, and libswscale sometimes messes
up when converting to full range too. (In this partricular case, we
found that converting rgba->yuv420p16 full range actually seems to
output limited range.)
This actually restores a similar heueristic from the late vf_scale.c.
|
| |

Finally get rid of all the HWDEC_* things, and instead rely on the
libavutil equivalents. vdpau still uses a shitty hack, but fuck the
vdpau code.
Remove all the now unneeded remains. The vdpau preemption thing was not
unused anymore; if someone cares this could probably be restored.

They were added to the "to deleted" list and never relicensed, because I
thought I'd delete them early. But it's possible that they'll stay in
mpv for a longer time, so relicense them. Still leaving them as
deprecated and scheduled for removal, so they can still be dropped once
there is a better way to deal with them, if they get annoying, or if a
better mechanism is found that makes them unnecessary.
All contributors agreed. There are some minor changes by people who did
not agree, but these are all not relevant or have been removed.

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.

We want to drop vf_scale, but we still need a way to auto convert
between imgfmts. In particular, vf.c will auto insert the "scale" filter
if the VO doesn't support a pixfmt.
To avoid chaos, create a new vf_convert.c filter, based on vf_scale.c,
but without the unrelicensed code parts. In particular, this filter does
not do scaling and has no options. It merely converts from one imgfmt to
another, if needed.

It seems this will be useful for Rokchip DRM hwcontext integration.
DRM hwcontexts have additional internal structure which can be different
depending on the decoder, and which is not part of the generic hwcontext
API. Rockchip has 1 layer, which EGL interop happens to translate to a
RGB texture, while VAAPI (mapped as DRM hwcontext) will use multiple
layers. Both will use sw_format=nv12, and thus are indistinguishable on
the mp_image_params level. But this is needed to initialize the EGL
mapping and the vo_gpu video renderer correctly.
We hope that the layer count is enough to tell whether EGL will
translate the data to a RGB texture (vs. 2 texture resembling raw nv12
data). For that we introduce MP_IMAGE_HW_FLAG_OPAQUE.
This commit adds the flag, infrastructure to set it, and an "example"
for D3D11.
The D3D11 addition is quite useless at this point. But later we want to
get rid of d3d11_update_image_attribs() anyway, while we still need a
way to force d3d11vpp filter insertion, so maybe it has some
justification (who knows). In any case it makes testing this easier.
Obviously it also adds some basic support for triggering the opaque
format for decoding, which will use a driver-specific format, but which
is not supported in shaders. The opaque flag is not used to determine
whether d3d11vpp needs to be inserted, though.

This should actually cover all of them, if you take into account that
some unchanged GPL source files include header files with such checks.
Also this was done already for the libaf derived code.

We allowed any input format that was generally supported by libva, but
this is probably nonsense, as the actual surface format was always fixed
to nv12. We would have to check whether libva can upload a given pixel
format to a nv12 surface. Or we would have to use a separate frame pool
for input surfaces with the exact sw_format - but then we'd also need to
check whether the vaapi VideoProc supports the surface type.
Hardcode nv12 and yuv420p as input formats, which we know can be
uploaded to nv12 surfaces. In theory we could get a list of supported
upload formats from libavutil, but that also require allocating a dummy
hw frames context just for the query.
Add a comment to the upload code why we can allocate an output surface
for input.
In the long run, we'll probably want to use libavfilter's vaapi
deinterlacer, but for now this would break at least user options.

This is needed for HAVE_SSE4_INTRINSICS. config.h used to be included as
a transitive dependency of vf.h, but the include statement was removed
from vf.h in 8f2ccba71bb4.

commit.

This removes all GPL only code from it, and that's the whole purpose.
Also happens to be much simpler.
The "deinterlace" option still sort of exists, but only as runtime
changeable option. The main change in behavior is that the property will
not report back the actual deint state. Or in other words, if inserting
or initializing the filter fails, the deinterlace property will still
return "yes". This is in line with most recent behavior changes to
properties and options.

I really wouldn't care much about this, but some parts of the core code
are under HAVE_GPL, so there's some need to get rid of it. Simply turn
the video equalizer from its current fine-grained handling with vf/vo
fallbacks into global options. This makes updating them much simpler.
This removes any possibility of applying video equalizers in filters,
which affects vf_scale, and the previously removed vf_eq. Not a big
loss, since the preferred VOs have this builtin.
Remove video equalizer handling from vo_direct3d, vo_sdl, vo_vaapi, and
vo_xv. I'm not going to waste my time on these legacy VOs.
vo.eq_opts_cache exists _only_ to send a VOCTRL_SET_EQUALIZER, which
exists _only_ to trigger a redraw. This seems silly, but for now I feel
like this is less of a pain. The rest of the equalizer using code is
self-updating.
See commit 96b906a51d5 for how some video equalizer code was GPL only.
Some command line option names and ranges can probably be traced back to
a GPL only committer, but we don't consider these copyrightable.
|
| |
|
|
|
|
|
|
|
| |
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.

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.

For vo_opengl and vo_direct3d, these are supported in a generic way.
For vf_vapoursynth, we could probably map its VSFormat struct in a
generic way, but for now do some bullshit.
vf_eq.c actually loses support for these formats. We could add generic
support too (anything that has 8 bit planes will work), but why bother.
The filter is deprecated anyway.

This prevents nasty surprises like the sig-peak still being left at 1.0

display-referred.

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.

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.

Most authors have agreed. Like with vo.c, we don't take module
declarations into consideration (see 0e09533c73dc0).
Notable issues:
115bfb9762: the author has (probably) not agreed. The vf.c changes were
removed with the removal of filter DR, though (see c54fc507da8e).
7b25afd742: the same author adds VOCTRLs for deinterlacing switching at
runtime. Put them under a HAVE_GPL ifdef just to be sure. (It looks like
we could remove the VOCTRLs immediately, as they're needed only for some
compatibility things, but no need to do that yet.)
02b199e5e9: the author had a conditional agreement to LGPL, which
doesn't allow us to change it just yet, but the code added here was
completely removed anyway. (These days, the pts is passed as mp_image
field, and put_image is gone.)
3532cd532e: same author, but code removed with DR removal.
f0626e2f8d: same author, but code was moved to mp_image.c.
e5b4b495c3: agreed to LGPLv3+ only, but the code was removed in
cfa1f9e082 anyway.
086c324692: author was not asked - minor warning fix, but no mpv
includes malloc.h anymore.
e9d0a1d609: author was not asked - removed again in 33b62af947.
c260a1139d: author could not be reached - but this code was removed when
mpv changed the image allocation code to essentially use FFmpeg's
pixdesc.

Until now, the texture pointer was stored in plane 1, and the texture
array index was in plane 2. Move this down to plane 0 and plane 1. This
is to align it to the new WIP D3D11 decoding API in Libav, where we
decided that there is no reason to avoid setting plane 0, and that it
would be less weird to start at plane 0.

If the VO doesn't support a format output by vf_lavfi, no conversion
filter was inserted, and filter chain creation failed.
This is because vf_lavfi doesn't properly follow the format negotiation
model, which means the format negotiation pass does not catch all cases
where conversion is needed. Specifically, vf_lavfi supports that all
output formats are supported for any given input format, but then does
not actually call vf_next_query_format() in reconfig() to check which
format it uses, but outputs whatever it gets from libavfilter.
I think this is ok to avoid excessive complexity in vf_lavfi.c, but it
also means adding more kludges to vf.c. I justify this (and the code
duplication) with the idea that the current filter chain code will die
anyway at some point.
The .log field additions for c->first/c->last are strictly speaking not
needed, but useful for debugging.

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.
|
| |
|
|
|
|
|
|
|
|
| |
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.
