It may be completely useless, and I can't verify it as no known samples
or other known/accessible software using it, but why not?
Putting this together with he 422 code requires making it slightly more
generic. I'm still staying with a "huge" if tree instead of a table to
select the scanline worker callback, because it's actually small and not
huge (although it not being generic still feels slightly painful).
Now everything is super generic and super undebuggable. Some awkwardness
because the new metadata is basically a transposed version of the
mp_regular_imgfmt metadata, which was used for component info before.
The old code ignored many corner cases, and even wrote "blacker than
black" to YUV images. Use the new pixel format metadata and other
recently added gimmicky crap, which should make this more correct. Even
the almighty fuckup of a format AV_PIX_FMT_UYYVYY411 should work,
although that couldn't be tested for obvious reasons.
This doesn't work for "monow", but this is so extremely fringe while at
the same time painful that I just won't care. In theory, it could be
modeled as some sort of inverted gray colorspace or something.
Make sure to accept only native endian mpv formats. Previously, it
didn't check, and simply matched LE, because these are usually defined
before the BE formats.
red_mask etc. are defined as unsigned long, so use that instead of
hardcoding a 32 bit limit.
A repeat of the previous useless commits.
Pondered whether to use separate fields or just a flags integer for
color and component types; the latter won for now.
Functions like mp_imgfmt_get_component_type() are now discouraged, and
mp_imgfmt_desc.flags is back for defining all information. Some days ago
I felt like the opposite would be the better design. Fortunately, it
doesn't matter.
With this, I think all image format properties that mpv needs are
exhaustively defined all in one place.
Execution of "stop" command in the case when idle mode was not enabled
resulted in player termination scenario not honoring user setting
"save-position-on-quit" from config file. This patch addresses the
issue by checking for "save-position-on-quit" in cmd_stop and saving
state when idle mode is not enabled.
Useless, but super generic! Actually may add support for other fringe
formats, however vo_x11 in itself is useless, so nothing won here. Also
I didn't bother with big endian support.
I guess I decided to stuff it all into mp_imgfmt_desc (the "old"
struct). This is probably a mistake. At first I was afraid that this
struct would get too fat (probably justified, and hereby happened), but
on the other hand mp_imgfmt_get_desc() (which builds the struct) calls
the former mp_imgfmt_get_layout(), and the separation doesn't make too
much sense anyway. Just merge them.
Still, try to keep out the extra info for packed YUV bullshit. I think
the result is OK, and there's as much information as there was before.
The test output changes a little. There's no independent bits[] array
anymore, so formats which did not previously have set this now show it.
(These formats are mpv-only and are still missing the metadata. To be
added later). Also, the output for the cursed packed formats changes.
Use the new pixfmt metadata to replace the format tables with weird
generic code.
As you can see, this removes the tables that essentially duplicate
information (which is baaaaaaaaaad), in exchange for code which is
probably more fragile and has less of a chance of being understood by
someone new to the code (which is probably even worse from a maintenance
and robustness point of view, but LALALA I CAN'T HEAR YOU).
There are some more formats which can be handled like this (RGB30 and
packed YUV I guess), maybe later.
My previous commit added support for this format, but it was still
broken, and prevented the allocation code from working. It's unknown
whether it's correct now (because this pixfmt is so obscure and useless,
there are no known samples around), but who cares.
Trying to use anything other than CLOCK_MONOTONIC here would be a
disaster. No idea if it's even possible for the clockid here to be
something other than CLOCK_MONOTONIC in this function but it's better
safe than sorry. Closes#7740.
I thought I'd probably want something like this, so the hardcoded stuff
in repack.c can be removed eventually. Of course this has no purpose at
all, and will not have any. (For now, this provides only metadata, and
nothing uses it, apart from the "test" that dumps it as text.)
This adds full support for AV_PIX_FMT_UYYVYY411 (probably out of spite,
because the format is 100% useless). Support for some mpv-only formats
is missing, ironically.
The code goes through _lengths_ to try to make sense out of the FFmpeg
AVPixFmtDescriptor data. Which is even more amazing that the new
metadata basically mirrors pixdesc, and just adds to it. Considering
code complexity and speed issues (it takes time to crunch through all
this shit all the time), and especially the fact that pixdesc is very
_incomplete_, it would probably better to have our own table to all
formats. But then we'd not scramble every time FFmpeg adds a new format,
which would be annoying. On the other hand, by using pixdesc, we get the
excitement to see whether this code will work, or break everything in
catastrophic ways.
The data structure still sucks a lot. Maybe I'll redo it again. The text
dump is weirdly differently formatted than the C struct - because I'm
not happy with the representation. Maybe I'll redo it all over again.
In summary: this commit does nothing.
Remove the vaguely defined plane_bits and component_bits fields from
struct mp_imgfmt_desc. Add weird replacements for existing uses. Remove
the bytes[] field, replace uses with bpp[].
Fix some potential alignment issues in existing code. As a compromise,
split mp_image_pixel_ptr() into 2 functions, because I think it's a bad
idea to implicitly round, but for some callers being slightly less
strict is convenient.
This shouldn't really change anything. In fact, it's a 100% useless
change. I'm just cleaning up what I started almost 8 years ago (see
commit 00653a3eb0). With this I've decided to keep mp_imgfmt_desc,
just removing the weird parts, and keeping the saner parts.
The image w and h members must match params.w and params.h, so
should not be changed directly. The helper function mp_image_set_size
is designed for this purpose, so just use that instead.
This prevents an assertion error with the rewritten draw_bmp.
Fixes#7721.
The generate_xxx() helpers, once defined, would appear as
user-visible functions; this would lead to unexpected and
confusing completion suggestions for gene<tab> after having
once run mpv in that shell.
This PR adds the prefix '_mpv_' to all completion functions
as a convention to make them less user-visible and less likely
to collide with other packages.
The OSC calls this "tooltip" (and although a general mechanism, there's
only one instance using it). One particular problem was that with the
default OSC layout, moving the mouse down and out of the window, the
tooltip stuck around, because the returned mouse position was the last
pixel row in the window, which still overlaps with the seek bar.
Instead of introducing mouse_in_window, you could check last_mouse_X for
nil, but I think this is clearer.
This returns (-1, -1) to the caller if the mouse is outside. Kind of
random, but works.
Added in libplacebo v60, unfortunately with some changes in design that
make it a bit of an awkward fit for the way timers are used in mpv.
Timer queries in libplacebo don't support "start" and "stop"-style
operations, and instead are attached directly to operations. The only
sane way of implementing this in the ra API is to have a single 'active
timer' that gets attached to every pass, taking care to sort distinct
operations into distinct pl_timer queries within that ra_timer.
This design unfortunately doesn't let us have multiple 'active timers'
concurrently, similar to the current such limitation in ra_gl. But it's
also not a big deal.
Before this, we pretty much guaranteed that --mpv-ipc-fd=3 would be
passed. The FD was hardcoded, so scripts started by this mechanism
didn't need to actually parse the argument. Change this to using a
mostly random FD number instead.
I decided to do this because posix_spawnp() and the current replacement
cannot "guarantee" a FD layout. posix_spawn_file_actions_adddup2() just
runs dup2() calls, so it may be hard to set FD 3/4 if they are already
used by something else. For example imagine trying to map:
{.fd = 3, .src_fd = 4},
{.fd = 4, .src_fd = 3},
Then it'd do dup2(4, 3), dup2(3, 4) (reminder: dup2(src, dst)), and the
end result is that FD 4 really maps to the original FD 4.
While this was not a problem in the present code, it's too messy that I
don't want to pretend it can always done this way without an unholy
mess. So my assumption is that FDs 0-2 can be freely assigned because
they're never closed (probably...), while for all other FDs only
pass-through is reasonable.
This code runs posix_spawnp() within a fork() in some cases, in order to
"disown" processes which are meant as being started detached. But
posix_spawnp() is not marked as async-signal-safe, so what we do is not
allowed. It could for example cause deadlocks, depending on
implementation and luck at runtime. Turns out posix_spawnp() is useless
crap.
Replace it with "classic" fork() to ensure correctness.
We could probably use another mechanism to start a process "disowned"
than doing a double-fork(). The only problem with "disowning" a process
is calling setsid() (which posix_spawnp() didn't support, but maybe will
in newer revisions), and removing as as parent from the child process
(the double-fork() will make PID 1 the parent). But there is no good way
to either remove us as parent, or to "reap" the PID in a way that is
safe and less of a mess than the current code. This is because
POSIX/UNIX is a miserable heap of shit. (Less shit than "alternatives"
like win32, no doubt.)
Because POSIX/UNIX is a miserable heap of shit, execvp() is also not
specified as async-signal-safe. It's funny how you can run a full
fledged HTTP server in an async-signal-safe context, but not start a
shitty damn process. Unix is really, really, really extremely bad at
this process management stuff. So we reimplement execvp() in an
async-signal-safe way.
The new code assumes that CLOEXEC is a thing. Since POSIX/UNIX is such a
heap of shit, O_CLOEXEC and FD_CLOEXEC were (probably) added at
different times, but both must be present. io.h defines them to 0 if
they don't exist, and in this case the code will error out at runtime.
Surely we could do without CLOEXEC via fallback, but I'll do that only
if at least 1 bug is reported wrt. this issue.
The idea how to report exec() failure or success is from musl. The way
as_execvpe() is also inspired by musl (for example, the list of error
codes that should make it fail is the same as in musl's code).
See manpage additions. This was requested, sort of. Although what has
been requested might be something completely different. So this is
speculative.
This also changes sub_get_text() to return an allocated copy, because
the buffer shit was too damn messy.
This does not normally happen. But since the --input-ipc-client option
can pass in raw FDs, it's probably a good thing in the interest of
making mistakes obvious. Without this, it just burned a core on invalid
FDs (poll() always returned immediately).
As discussed in the referenced issue. This is quite a behavior change,
bit since this option is new, and not included in any releases yet, I
think it's OK.
Fixes: #7648
Render most of the OSD on the CPU, then draw it using a relatively
simple method. Do this for minimum code maintenance overhead. (While it
doesn't matter for vo_direct3d, and the effort spent here is probably
more than this would ever hope, I do hope to simplify the internal OSD
API for all these fringe VOs. Only vo_gpu should be allowed to do more
sophisticated things.)
If your GPU is shit (which it will be if you "want" to use vo_direct3d),
this might actually improve performance... is what I'd say, but out of
laziness a full screen sized texture gets uploaded on every OSD/subtitle
change, so maybe not.
This isn't useful anymore. We have a much better d3d11 renderer in
vo_gpu. D3D11 is available in all supported Windows versions. The
StretchRect path might still be useful for someone (???), and leaving it
at least evades conflict about users who want to keep using this VO for
inexplicable reasons. (Low power usage might be a justified reason, but
still, no.)
Also fuck the win32 platform, it's a heap of stinky shit. Microsoft is
some sort of psycho clown software company. Granted, maybe still better
than much of the rest of Silly Con Valley.
The original solution for #7017 was sort of a hack, but this hack is no
longer needed because c05e5d9d fixed the underlying issue causing this
error to be spammed in the first place. So just remove the "fix" that
apparently introduced about as many issueas it fixed.
Fixes#7719, hopefully.
Whatever it's worth. Instead of doing a pretty stupid conversion to
float, just blend it directly. This works for most RGB formats that are
8 bits per component or below (the latter because we expand packed
fringe RGB formats for simplicity). For higher bit depth RGB this would
need extra code.
This checked params->color.space for being RGB. If the colorspace is
unset, this did dumb things because even if the imgfmt was a RGB one,
the colorspace was not set to RGB. This actually also happened to the
tests.
(Short-cutting RGB like this is actually wrong, since RGB could still
have strange gamma or primaries, which would warrant a full conversion.
So you'd need to check for these other parameters as well. To be fixed
later.)
This will probably make it slower. But since I don't care about
vo_vaapi, that's perfectly OK. It serves mostly as a test for the
previous commit. In addition, this code was pretty bad (custom broken
scaling and not-blending that probably broke in some situation). If that
wasn't enough, some vaapi drivers also provide only a single overlay at
a time, while this code required a bunch.
There also seems to be a Mesa bug: the overlay gets stretched when
src_x/y was not 0. Or maybe I misunderstood how this is supposed to
work. A bug is probably more likely? Nobody cares about this API.
Maybe this is useful for some of the lesser VOs. It's preferable over
bad ad-hoc solutions based on the more complex sub_bitmap data
structures (as observed e.g. in vo_vaapi.c), and does not use that much
more code since draw_bmp already created such an overlay internally.
But I still wanted something that avoids having to upload/render a full
screen-sized overlay if for example there's only a tiny subtitle line on
the bottom of the screen. So the new API can return a list of modified
pixels (for upload) and non-transparent pixels (for display). The way
these pixel rectangles are computed is a bit dumb and returns dumb
results, but it should be usable, and the implementation can change.
They are sort of confusing, and they hide the fact that they have an
alpha component. Using the actual formats directly is no problem, sicne
these were useful only for big endian systems, something we can't test
anyway.
