As suggested by the zimg author: active_region is not supported on
outputs (and the API returns an error), so instead scale to the "full"
surface, but adjust the source rectangle such that the cropped output
image happens to cover the correct region.
Does this even work? Since Balmer Peak doesn't work, I can't really say,
but it seems to look correct.
X11 is in fact beautiful and superior to Wayland. Instead, just state
what the problem is in most cases: software scaling. (We have
accelerated X11 rendering in vo_gpu and others.)
This was a confusing name, because 1. there's also a z_planes[] field,
and 2. it was not specific to zimg indexes.
Possibly there used to be an idea involved about supporting alpha to
non-alpha formats by discarding the alpha plane, but zimg does this now
(and zimg will correctly blend the alpha component too).
The special thing about this format is
1. mpv assigns the component ID 4 to alpha, and component IDs 2 and 3
are not present, which causes some messy details.
2. zimg always wants the alpha plane as plane 3, and plane 1 and 2 are
not present, while FFmpeg/mpv put the alpha plane as plane 1.
In theory, 2. could be avoided, since FFmpeg actually doesn't have a any
2 plane formats (alpha is either packed, or plane 3). But having to skip
"empty" planes would break expectations.
zplanes is not equivalent to the mpv plane count (actually it was always
used this way), while zimg does not really have a plane count, but does,
in this case, only use plane 0 and 3, while 2 and 3 are unused and
unset. z_planes[] (not zplanes) is now always valid for all 4 array
entries (because it uses zimg indexes), but a -1 entry means it's an
unused plane.
I wonder if these conventions taken by mpv/zimg are not just causing
extra work. Maybe component IDs should just be indexes by the "natural"
order (e.g. R-G-B-A, Y-U-V-A, Y-A), and alpha should be represented as a
field that specifies the component ID for it, or just strictly assume
that 2/4 component formats always use the last component for alpha.
We reorder the planes between mpv and zimg conventions. It turns out the
code still confused when which convention was used.
So the way it actually works is that the _only_ place where zimg order
is used is the zimg_image_buffer.plane[] array. plane_aligned[] and
zmask[] were accessed incorrectly, although I guess it rarely had a
reason to fail (plane reordering is mostly for RGB, which has planes of
all the same size).
Adjust some comments accordingly too.
The zimg wrapper "needs" these formats as intermediary when repacking
the normal gray/alpha packed format. The packed format is used by the
png decoder and encoder, and is thus interesting.
Unfortunately, mpv-only formats are a mess right now, because all the
existing code is focused around using the FFmpeg metadata for pixel
formats. This should be improved, but not now, so make the mess worse.
This commit doesn't add support for it to the zimg wrapper yet.
libzimg recently added direct alpha support and new API for it. (The API
change is rather minimal, and it turns out we can easily support old and
new zimg versions.)
This does not support _all_ alpha formats. For example, gray + alpha is
not supported yet, because my stupid design in the zimg wrapper would
require a planar gray + alpha format, while ffmpeg provides only a
packed one.
the macOS config was only used in cocoa-cb before and only included when
it was available. since this config is meant for general macOS options
and backend independent options we include it when cocoa is available.
one of the options is already used in the old cocoa backend, which broke
using it when build without swift or cocoa-cb support.
Fixes#7449
The bash completion seems to be working decently at this point, so I
feel comfortable caching the options output to improve the performance
of the completion.
The change, in an earlier commit, in format for ass to handle results
in a different number of fields to skip. Correct that so SDH filtering
works.
Should fix issue #7188
As requested I guess. It behaves quite similar to the --loop* options.
Not quite happy with the idea that 1) the option is mutated on each
operation (but at least it's consistent with --loop* and doesn't require
more properties), and 2) the ab-loop command will do nothing once all
loop iterations are done. As a concession, the OSD shows something about
"disabled".
Fixes: #7360
This is not really a changelog, but rather a list of potentially
breaking changes API- and normal users should be aware of, and to help
with migration from older mpv releases.
for reasons unknown to me the NSCursor (un)hide functions can be
completely unreliable and the cursor can have an unknown state. this
only happens on some system and wasn't able to reproduce this. it's
probably some dumb race condition that might be possible to work around,
though because of the lack of reproducibility on my end it's hard to
test.
i decided to rework the cursor hiding code yet again and make it a lot
less greedy. the cursor will now always unhide when moved and there
will never be a situation again the cursor can't be unhidden again.
on the other hand there might be edge cases now where the cursor won't
hide immediately and you have to move it slightly to make it disappear
again. this should be an acceptable tradeoff.
Fixes#6886
this creates a default log for the last mpv run when started from the
bundle. that way one can get a log of what happened even after an issue
occurred. also add a menu entry under Help to show the current log, but
only when the bundle is used.
Fixes#7396Fixes#2547
Wayland uses vo_wayland_wait_frame plus some polling with a timeout for
blocking on vsync. Here are a couple of changes that seem to be
improvements. First, the poll time is always rounded up instead of
truncated. When rendering frames longer than the standard 16.666 ms
timeout, it seems that truncating the poll time slightly early may cause
some vsync jitter spikes. Waiting longer, even if it's too long, appears
to behave better.
The second change is to use wl_display_roundtrip instead of
wl_display_dispatch_pending. wl_display_dispatch_pending dispatches all
events immediately. This is good to avoid blocking, but it's not
guaranteed to wait long enough for all events to be processed on the
display fd. The preceding wl_display_read_events routine ensures that
all events on the display fd are queued. We just need a semi-blocking
routine to dispatch them for the most reliable vsync.
wl_display_roundtrip will dispatch any events for us, but also wait for
a reply from the display server. This makes it ideal for this role. If
the compositor doesn't reply to the client something else is probably
horribly broken and wrong anyway. It's also not a permanently blocking
call like wl_display_dispatch. If there's no frame callback (i.e. the
window is hidden), then it does not dispatch any events and returns
immediately.
Directories inside ~~/scripts/ are now loaded as scripts, so don't use
it also for modules. Now there are no default module paths.
To compensate, we now try to run ~~/.init.js right after defaults.js,
so the user may extend the js init procedure via this script, e.g. for
adding default paths to mp.module_paths .
While mpv normally uses the text a key produces (as opposed to physical
key mappings), this is different with the keypad. This is for the sake
of making it possible to distinguish between these keys and the normal
number keys on the left side of a full size keyboard.
There were complaints that the keypad doesn't interact with console.lua,
so manually map them. This ignores numlock (behaves as if it's always
on), and maps KP_DEC to "." (even though it's mapped to "," on some
keyboards). The /*-+ keys produce ASCII on mpv (at least with X11) as an
inexplicable inconsistency, so there are no mappings for these.
Fixes: #7431
Due to asynchronicity, we generally can't guarantee that a video frame
matches up with other events such as playback time change exactly (since
decoding, presentation, and property update all happen at different
times). This is a complaint in the referenced bug report, where
screenshot filenames in each-frame screenshot did not use the correct
timestamp, and instead was lagging behind by 1 frame.
But in this case, synchronicity was already pretty much forced with wait
calls. The only problem was that the playback time was updated at a
later time, which results in the observed 1 frame lag. Fix this by
moving the place where the screenshot is triggered in this mode.
Normal screenshots may still have the old problem. There is no effort
made to guarantee the timestamps absolutely line up, same as with the
OSD. (If you want a guarantee, you need to use a video filter, such as
libavfilter's drawtext. These will obviously use the proper timestamp,
instead of going through the somewhat asynchronous property etc. system
in the player frontend.)
Fixes: #7433
See #7435 and related for context.
Basically, it seems that while the original vsfilter processed subtitles
like with this option set to "yes", many current players (mpc-hc
default, vlc, probably most libass users) treat them like with "no". In
the linked issue, this makes rendering severely slower, and can consume
a lot of memory (or just overflow libass memory calculations). It seems
that changing this to "no" will lead to more good than bad, especially
because newer subtitles may be authored for the "no" behavior.
Most libass users seem to use "no" exactly because they do not call
ass_set_storage_size() at all. This API was needed because the scaling
of the subtitles depends on the video size (vsfilter bugs, or
something). In addition, it's my personal opinion that rendering should
not depend on the video at all, so I like setting the default of this to
"no".
The script was set up to only call on_update when the changelist
was non-empty. However, since the size operator does not operate
on dicts, it always returned 0 (which is truthy), thus on_update
would always be called when the script-opts property changed.
When switching between having a video visible or not,
stats.lua now picks up the required formatting changes
for the cache stats page to display correctly.
The recently added feature to load scripts from a sub-directory. A
problem was that the script name was still derived from the actual
script source file that was loaded, which was always "main.lua" (or
similar), resulting in "main" as name.
Fix this by using the directory name.
One odd corner case is that you can do "--script=/path/foo////". As by
POSIX semantics, the extra "/" are ignored. However, the newly added
code strips only one separator, so mp_basename() returns "" (as it
should), and the empty name makes mp_new_client() fail in turn. I don't
really care about this, just don't do it. But mp_new_client() failure
was silent (since it normally never happens), so add at least an error
message for that, instead of being entirely silent.
There were a couple of erroneous things in the handle_toplevel_config
function. Firstly, looping through the different states was not handled
correctly. Launching a window as maximized (can happen in sway for
example) was always stuck on true and would never be set to false. Fix
this by always checking if XDG_TOPLEVEL_STATE_MAXIMIZED is found or not.
Also do a similar thing for the fullscreen state.
Additionally, there were some issues with resizing windows and
window-scale going back to old sizes. The root of this problem is that
the width and height arguments of handle_toplevel_config aren't actually
guarenteed to be the actual width and height of the surface. There are
times when mpv will set the surface size on its own (like with
window-scale) which will be unknown to the toplevel listener. To
complicate matters, there are times when we do want to use the width and
height arguments (like when resizing with the mouse).
Fix this by checking if the width and height arguments reported by
handle_toplevel_config changed from the previous call of the function.
If the value is different, then we go ahead and use them when setting
mpv's geometry. If not, then we just ignore it.
win32 is a cursed abomination which has "drive letters" at the root of
the filesystem namespace for no reason. This requires special handling
beyond tolerating the idiotic "\" path separator.
Even more cursed is the fact that a path starting with a drive letter
can be a relative path. For example, "c:billsucks" is actually a
relative path to the current working directory of the C drive. So for
example if the current working directory is "c:/windowsphone", then
"c:billsucks" would reference "c:/windowsphone/billsucks".
You should realize that win32 is a ridiculous satanic trash fire by the
point you realize that win32 has at least 26 current working
directories, one for each drive letter.
Anyway, the actual problem is that mpv's mp_path_join() function would
return a relative path if an absolute relative path is joined with a
drive-relative path. This should never happen; I bet it breaks a lot of
assumptions (maybe even some security or safety relevant ones, but
probably not).
Since relative drive paths are such a fucked up shit idea, don't try to
support them "properly", and just solve the problem at hand. The
solution produces a path that should be invalid on win32.
Joining two relative paths still behaves the same; this is probably OK
(maybe).
The change isn't very minimal due to me rewriting parts of it without
strict need, but I don't care.
Note that the Python os.path.join() function (after which the mpv
function was apparently modeled) has the same problem.
