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 is pretty pointless, but I believe it allows us to claim that the
new code is not affected by the copyright of the old code. This is
needed, because the original mp_audio struct was written by someone who
has disagreed with LGPL relicensing (it was called af_data at the time,
and was defined in af.h).
The "GPL'ed" struct contents that surive are pretty trivial: just the
data pointer, and some metadata like the format, samplerate, etc. - but
at least in this case, any new code would be extremely similar anyway,
and I'm not really sure whether it's OK to claim different copyright. So
what we do is we just use AVFrame (which of course is LGPL with 100%
certainty), and add some accessors around it to adapt it to mpv
conventions.
Also, this gets rid of some annoying conventions of mp_audio, like the
struct fields that require using an accessor to write to them anyway.
For the most part, this change is only dumb replacements of mp_audio
related functions and fields. One minor actual change is that you can't
allocate the new type on the stack anymore.
Some code still uses mp_audio. All audio filter code will be deleted, so
it makes no sense to convert this code. (Audio filters which are LGPL
and which we keep will have to be ported to a new filter infrastructure
anyway.) player/audio.c uses it because it interacts with the old filter
code. push.c has some complex use of mp_audio and mp_audio_buffer, but
this and pull.c will most likely be rewritten to do something else.
This extracts non-ANGLE specific code to d3d11_helpers.c, which is
modeled after egl_helpers.c. Currently the only consumer is
context_angle.c, but in future this may allow the D3D11 device and
swapchain creation logic to be reused in other backends.
Also includes small improvements to D3D11 device creation. It is now
possible to create feature level 11_1 devices (though ANGLE does not
support these,) and BGRA swapchains, which might be slightly more
efficient than ARGB, since its the same format used by the compositor.
Actually GL-specific parts go into gl_utils.c/h, the shader cache
(gl_sc*) into shader_cache.c/h.
No semantic changes of any kind, except that the VAO helper is made
public again as part of gl_utils.c (all while the goal for gl_utils.c
itself is to be included by GL-specific code).
This starts work on moving OpenGL-specific code out of the general
renderer code, so that we can support other other GPU APIs. This is in
a very early stage and it's only a proof of concept. It's unknown
whether this will succeed or result in other backends.
For now, the GL rendering API ("ra") and its only provider (ra_gl) does
texture creation/upload/destruction only. And it's used for the main
video texture only. All other code is still hardcoded to GL.
There is some duplication with ra_format and gl_format handling. In the
end, only the ra variants will be needed (plus the gl_format table of
course). For now, this is simpler, because for some reason lots of hwdec
code still requires the GL variants, and would have to be updated to
use the ra ones.
Currently, the video.c code accesses private ra_gl fields. In the end,
it should not do that of course, and it would not include ra_gl.h.
Probably adds bugs, but you can keep them.
Now it's sourced from the etc/ PNG files directly, instead of
preprocessing them with imagemagick.
Add some ad-hoc code to decode PNG files with libavcodec. At least we
can drop the zlib code in exchange.
This partially reverts the change from a longer time ago to always build
DXVA2 and D3D11VA together.
To make it simpler, we change the following:
- building with ANGLE headers is now required to build D3D hwaccels
- if DXVA2 is enabled, D3D11VA is still forcibly built
- the CLI vo_opengl ANGLE backend is now under --egl-angle-win32
This is done to reduce the dependency mess slightly.
In a bunch of cases, we emulate highly platform specific APIs on a
higher level across all OSes, such as IPC, terminal, subprocess
handling, and more. We have source files for each OS, and they implement
all the same mpv internal API.
Selecting which source file to use on an OS can be tricky, because there
is partially overlapping and emulated APIs (consider Cygwin on Windows).
Add a pick_first_matching_dep() function to make this slightly easier
and more structured.
Also add dummy backends in some cases, to deal with APIs not being
available.
Clarify the Windows dependency identifiers, as these are the most
confusing.
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.
Implements JS with almost identical API to the Lua support.
Key differences from Lua:
- The global mp, mp.msg and mp.utils are always available.
- Instead of returning x, error, return x and expose mp.last_error().
- Timers are JS standard set/clear Timeout/Interval.
- Supports CommonJS modules/require.
- Added at mp.utils: getenv, read_file, write_file and few more.
- Global print and dump (expand objects) functions.
- mp.options currently not supported.
See DOCS/man/javascript.rst for more details.
This drops support for the old libavcodec APIs. Now FFmpeg 3.3 or FFmpeg
git is required. Libav has no release with the new APIs yet, so for
Libav git as of a few weeks or months ago or so is required if you want
to use Libav.
Not much actually changes in hwdec_vaegl.c - some code is removed, but
the reindentation inflates the diff.
And also change input.conf to make all screenshots async. (Except the
every-frame mode, which always uses synchronous mode and ignores the
flag.) By default, the "screenshot" command is still asynchronous,
because scripts etc. might depend on this behavior.
This is only partially async. The code for determining the filename is
still always run synchronously. Only encoding the screenshot and writing
it to disk is asynchronous. We explicitly document the exact behavior as
undefined, so it can be changed any time.
Some of this is a bit messy, because I wanted to avoid duplicating the
message display code between sync and async mode. In async mode, this is
called from a worker thread, which is not safe because showing a message
accesses the thread-unsafe OSD code. So the core has to be locked during
this, which implies accessing the core and all that. So the code has
weird locking calls, and we need to do core destruction in a more
"controlled" manner (thus the outstanding_async field).
(What I'd really want would be the OSD simply showing log messages
instead.)
This is pretty untested, so expect bugs.
Fixes#4250.
Reallows enabling dvdnav without enabling dvdread which was broken
in 77cbb3543 when they were both disabled by default.
Since dvdnav requires dvdread, we can enable dvdread:// even if
--enable-dvdread isn't passed.
Fixes#4290
Add subtitle filter to remove additions for deaf or hard-of-hearing
(SDH). This is for English, but may in part work for others too.
This is an ASS filter and the intention is that it can always be
enabled as it by default do not remove parts that may be normal text.
Harder filtering can be enabled with an additional option.

This was mostly self-contained, so its removal makes w32_common.c a bit
easier to read. Also, because it was self contained and its author has
agreed to LGPL relicencing, the new file has the LGPL licence header.
Remove low quality drc filter. Anyone whishing to have dynamic range
compression should use the much more powerful acompressor ffmpeg filter:
mpv --af=lavfi=[acompressor] INPUT
Or with parameters:
mpv --af=lavfi=[acompressor=threshold=-25dB:ratio=3:makeup=8dB] INPUT
Refer to https://ffmpeg.org/ffmpeg-filters.html#acompressor for a full
list of supported parameters.

The new API works like the new vaapi API, using generic hwaccel support.
One minor detail is the error message that will be printed if using
non-4:2:0 surfaces (which as far as I can tell is completely broken in
the nVidia drivers and thus not supported by mpv). The HEVC warning
(which is completely broken in the nVidia drivers but should work with
Mesa) had to be added to the generic hwaccel code.
This also trashes display preemption recovery. Fuck that. It never
really worked. If someone complains, I might attempt to add it back
somehow.
This is the 4th iteration of the libavcodec vdpau API (after the
separate decoder API, the manual hwaccel API, and the automatic vdpau
hwaccel API). Fortunately, further iterations will be generic, and not
require much vdpau-specific changes (if any at all).
As the manpage says, this has no value other than adding bugs.
It uses code based on context_x11.c, and basically does very stripped
down context creation (no alpha support etc.). It uses vdpau for
display, and maps vdpau output surfaces as FBOs to render into them.
This might be good to experiment with asynchronous presentation. For
now, it presents synchronously, with a 4 frame delay (which should whack
off A/V sync). The forced 4 frame delay is probably also why interaction
feels slower.
There are some weird vdpau errors on resizing and uninit. No idea what
causes them.
hw_vaapi.c didn't do much interesting anymore. Other than the function
to create a device for decoding with vaapi-copy, everything can be done
by generic code. Other libavcodec hwaccels are planned to provide the
same API as vaapi. It will be possible to drop the other hw_ files in
the future. They will use this generic code instead.
This was a hack to let libmpv API users pass a d3d device to mpv. It's
not needed anymore for 2 reasons:
1. ANGLE does not have this problem
2. Even native GL via nVidia (where this failed) seems to not require
this anymore
Implements --hwdec=videotoolbox on iOS. Similar to hwdec_osx.c, but
using CVPixelBuffer APIs available on iOS instead of the equivalent
IOSurface APIs in macOS.
The code for copying a videotoolbox surface to mp_image was duplicated
(with some minor differences - I picked the hw_videotoolbox.c version,
because it was "better"). mp_imgfmt_from_cvpixelformat() is somewhat
duplicated with the vt_formats[] table, but this will be fixed in a
later commit, and moving the function to shared code is preparation.
This basically reuses the scripting infrastructure.
Note that this needs to be explicitly enabled at compilation. For one,
enabling export for certain symbols from an executable seems to be quite
toolchain-specific. It might not work outside of Linux and cause random
problems within Linux.
If C plugins actually become commonly used and this approach is starting
to turn out as a problem, we can build mpv CLI as a wrapper for libmpv,
which would remove the requirement that plugins pick up host symbols.
I'm being lazy, so implementation/documentation are parked in existing
files, even if that stuff doesn't necessarily belong there. Sue me, or
better send patches.
The old API is deprecated, and libavcodec prints a warning at runtime.
The new API is a bit nicer and does many things for you, such as
managing the underlying hwaccel decoder. libavutil also provides code
for managing surfaces (we use their surface pool).
The new code does not contain any code from the original MPlayer VAAPI
patch (that was used as base for some of the vaapi code in mpv). Thus
the new code is LGPL.
The new API actually does not add any visible symbols, so the only way
to detect it is a version check. Of course, the versions overlap
between FFmpeg and Libav, which requires additional care. The new
API did not get merged into FFmpeg yet, so there's no check for
FFmpeg.
The reST contents directive is added to mpv.rst.
In wscript_build.py, the --strip-elements-with-class=contents option is
needed for the rst2man call in order to prevent the TOC from appearing
in mpv.1.
'cuda-gl' isn't right - you can turn this on without any GL and
get some non-zero benefit (with the cuda-copy hwaccel). So
'cuda-hwaccel' seems more consistent with everything else.
Move the embedded string with the builtin profiles to a separate
builtin.conf file. This makes it easier to read and edit, and you can
also check it for errors with --include=etc/builtin.conf. (Normally
errors are hidden intentionally, because there's no way to output error
messages this early, and because some options might not be present on
all platforms or with all configurations.)
Minimal support just for testing.
Only the window surface creation (including size determination) is
really platform specific, so this could be some generic thing with
platform-specific support as some sort of sub-driver, but on the other
hand I don't see much of a need for such a thing.
While most of the fbdev usage is done by the EGL driver, using this
fbdev ioctl is apparently the only way to get the display resolution.
