Defining MPV_CPLUGIN_DYNAMIC_SYM during plugin compilation will replace mpv_*
functions with function pointers. Those pointer will be initialized when
loading the plugin.
It is recommended to use this symbol table when targeting Windows. The loader
does not have notion of global symbols. Loading cplugin into mpv process will
not allow this plugin to call any of the symbols that may be available in
other modules. Instead cplugin has to link explicitly to specific PE binary,
libmpv-2.dll/mpv.exe or any other binary that may have linked mpv statically.
This limits portability of cplugin as it would need to be compiled separately
for each of target PE binary that includes mpv's symbols. Which in practice
is unrealictis, as we want one cplugin to be loaded without those restrictions.
Instead of linking to any PE binary, we create function pointer for all mpv's
exported symbols. For convinience names of entrypoints are redefined to those
pointer so no changes are required in cplugin source code, except defining
MPV_CPLUGIN_DYNAMIC_SYM. Those function pointer are exported to make them
available for mpv to init with correct values during runtime, before calling
`mpv_open_cplugin`.
Note that those pointer are decorated with `selectany` attribute, so no need
to worry about multiple definitions, linker will keep only single instance.
This fixes cplugin usability on Windows. Without any API changes, only
recompilation with -DMPV_CPLUGIN_DYNAMIC_SYM is needed.
The goal is to provide simple to understand quality/performance level
profiles for the users.
Instead of default and gpu-hq profile. There main profiles were added:
- fast: can run on any hardware
- default: balanced profile between quality and performance
- high-quality: out of the box high quality experience. Intended
mostly for dGPU.
Summary of three profiles, including default one:
[fast]
scale=bilinear
cscale=bilinear (implicit)
dscale=bilinear
dither=no
correct-downscaling=no
linear-downscaling=no
sigmoid-upscaling=no
hdr-compute-peak=no
[default] (implicit mpv defaults)
scale=lanczos
cscale=lanczos
dscale=mitchell
dither-depth=auto
correct-downscaling=yes
linear-downscaling=yes
sigmoid-upscaling=yes
hdr-compute-peak=yes
[high-quality] (inherits default options)
scale=ewa_lanczossharp
cscale=ewa_lanczossharp (implicit)
hdr-peak-percentile=99.995
hdr-contrast-recovery=0.30
allow-delayed-peak-detect=no
deband=yes
scaler-lut-size=8
296d40dc6f changed how the vo handled
redraw requests in order to fix a race condition that can occur with
pausing. However, there was a slight oversight because a redraw request
that occurred while the core was unlocked and the video was still
playing would still be kept true (previously, this was always cleared).
That redraw is essential if mpv is paused otherwise the old issue comes
back, but if the video is playing it's unnecessary since the next loop
around will simply draw whatever we needed. The extra redraw could cause
a frame drop for some people in certain instances, so the solution is to
simply always clear redraw requests if !in->paused. This eliminates the
extra redraw but still keeps it when pausing.
Fixes#12426 and fixes#11579.
After fixing the B and C params for bcspline, it ended up being the same
thing as bicubic. There's no reason to have two names for the same
filter, so remove bcspline and keep bicubic to match libplacebo.
All we have to do is set VO_CAP_ROTATE90 and then use buffer transform.
Maybe ideally we would rotate with vavpp instead if possible, but this
would be a convoluted mess that I'm not really interested in dealing
with right now.
No need for this since it's entirely redundant with just changing the
filter radius directly. In fact, that's the whole *point* of the filter
radius - it does not modify the filter, it modifies the scaling of the
window.
Of course, this does not work for non-resizable kernels. But, really,
who cares?
Replaced by mathematically and numerically precise constants, the result
of exact computation. Also updates the description to provide more
explanation and motivation.
We currently always scaled the window to the size of the configured
radius. However, this is wrong - we should instead be scaling it to the
size of the sharpened/blurred kernel. Since the window is always
stretched to the configured size of the filter, we can accomplish this
easily by just multiplying the blur value into the filter radius
directly, and then using that adjusted radius in place of `f.radius`
everywhere.
On a side note, this gives a very minor performance boost to
ewa_lanczossharp for no downside.
Upstream finally caved in to peer pressure and added this filter. Of
course, this also removes the fallback for people on older versions of
libplacebo, but people using mpv git master are probably using
libplacebo git master anyway. It's time to debloat this code.
And make it the default. In libplacebo, this uses internal heuristics to
pick a good size based on the actual ICC characteristics. This is
significantly less wasteful than always generating a 64x64x64 3DLUT (the
old status quo).
In vo_gpu, for simplicity, just default to 65x65x65. Note that this
provides slightly better accuracy than the old default of 64x64x64 for
technical reasons, and matches what libplacebo defaults to for typical
display profiles.
Upstream has moved from passing struct pl_icc_profile to directly
attaching a managed pl_icc_object, plus providing a new function
pl_icc_update to update the ICC profile object parameters (if needed).
To facilitate this move, pull our ICC params back out of pl_options and
update the target ICC object directly.
The original OML sync implementation (which is where this calculation
originally comes from) made now_monotonic and ust_mp_time unsigned. This
is fine except it has the assumption that now_monotonic is always
greater than ust. This actually isn't always the case. In wayland, I
observed instances where the reported timestamp is in the future. Of
course, it's a valid question to wonder if this even makes sense but
these UST values are essentially opaque black boxes to us anyways. It's
entirely plausible that the gpu is expecting the actual presentation of
the last swap to be a bit in the future, the compositor gets this and
reports this to us. So we'll consider such stats as valid. Note that
xorg doesn't have this problem because it's roughly one swap buffer call
behind because of how the event loop works (honestly something that
should be fixed).
Of course, the problem with the unsigned type here is that it overflows
on the subtraction so make it signed and allow the appropriate negative
value to happen if it does. Note that this will simply result in a small
addition to mp_time_us() which is exactly what we want here (timestamp
slightly in the future). Some small style changes included just because.
This option behaves the same as the builtin one, and if it's value
is anything other then recursive|lazy|ignore it will fall back on the
builtin one as a sort of "auto" mode. It defaults to that auto mode.
Adds support for adding directories to the playlist in addition to
files. The propertiy `directory-mode` controls if directories get added.
Recursive directory loading will get added in a later commit.
Directories get sorted after files to behave the same way mpv
behaves when it loads directories directly.
The GNOME Nautilus file manager supports browsing of dav:// and davs:// links only. Additionally, dav:// and davs:// are also types of webdav links. Therefore, adding an "or" operation to include support for dav:// and davs:// links.
Adds catmull_rom as an example for --scale in the user manual, alongside
a brief description of the filter.
catmull_rom was only exposed to users as an available filter through
--scale=help. However, catmull_rom is very often aliased as "Bicubic" in
other applications such as GIMP and VapourSynth, and is a relatively
popular resizing filter. The documentation lacked any description of
catmull_rom, outside of a brief mention of it in the --tscale section.
Packet duration is not necessarily related to the display time of the
subtitle. Use start/end_display_time fields as source of the timing.
Fixes subtitles with infinite duration that should be on screen until
next sub is displayed.
While this resolves limitations of lavc decoder crop, it also introduces
artifacts with some of the source files or hwdec.
Depending on chroma sampler it is possible to sample outside the decoder
crop area, pulling dirty pixels into the image. Some decoders left them
zeroed, not black. To fix that we would need specifc solution during
mapping of avframes.
As most of the files require the crop only in bottom/right area, the
AVCodecContext::apply_cropping works ok for those.
For all other cases that require more fancy cropping like 1440x1080+240+0
user can manually set `--vd-apply-cropping=no`.
Limitations of the lavc crop are explained here:
