This hack was part of a solution to VSync judder in desktop OpenGL on
Windows. Rather than using blocking-SwapBuffers(), mpv could use
DwmFlush() to wait for the image to be presented by the compositor.
Since this would only work while the compositor was running, and the
compositor was silently disabled when OpenGL entered exclusive
fullscreen mode, mpv needed a way to detect exclusive fullscreen mode.
The code that is being removed could detect exclusive fullscreen mode by
checking the state of an undocumented mutex using undocumented native
API functions, but because of how fragile it was, it was always meant to
be removed when a better solution for accurate VSync in OpenGL was
found. Since then, mpv got the dxinterop backend, which uses desktop
OpenGL but has accurate VSync. It also got a native Direct3D 11 backend,
which is a viable alternative to OpenGL on Windows.
For people who are still using desktop OpenGL with WGL, there shouldn't
be much of a difference, since mpv can use other API functions to detect
exclusive fullscreen.
Refactored and split the `reinit_window_state` code into four
separate functions:
- `update_window_style` used to update window styles without
modifying the window rect.
- `fit_window_on_screen` used to adjust the window size when it is
larger than the screen size. Added a helper function `fit_rect` to
fit one rect on another without using any data from w32 struct.
- `update_fullscreen_state` used to calculate the new fullscreen
state and adjust the window rect accordingly.
- `update_window_state` used to display the window on screen with
new size, position and ontop state.
This commit fixes three issues:
- fixed#4753 by skipping `fit_window_on_screen` for a maximized
window, since maximized window should already fit on the screen.
It should be noted that this bug was only reproducible with
`--fit-border` option which is enabled by default. The cause of the
bug is that after calling the `add_window_borders` for a maximized
window, the rect in result is slightly larger than the screen rect,
which is okay, `SetWindowPos` will interpret it as a maximized state
later, so no auto-fitting to screen size is needed here.
- fixed#5215 by skipping `fit_window_on_screen` when leaving fullscreen.
On a multi-monitor system if the mpv window was stretched to cover
multiple monitors, its size was reset after switching back from
fullscreen to fit the size of the active monitor. Also, when changing
`--ontop` and `--border` options, now only the
`update_window_style` and `update_window_state` functions are used,
so `fit_window_on_screen` is not used for them too.
- fixed#2451 by moving the `ITaskbarList2_MarkFullscreenWindow`
below the `SetWindowPos`. If the taskbar is notified about fullscreen
state before the window is shown on screen, the taskbar button could
be missing until Alt-TAB is pressed, usually it was reproducible on
Windows 8.
Other changes:
- In `update_fullscreen_state` the `reset window bounds` debug
message now reports client area size and position, instead of window area
size and position. This is done for consistency with debug messages
in handling fullscreen state above in this function, since they also print
window bounds of the client area.
- Refactored `gui_thread_reconfig`. Added a new window flag `fit_on_screen`
to fit the window on screen even when leaving fullscreen. This is needed
for the case when the new video opened while the window is still in the
fullscreen state.
- Moved parent and fullscreen state checks out from the WM_MOVING to
`snap_to_screen_edges` function for consistency with other functions.
There's no point in keeping these checks out of the function body.
When window and screen size and position are stored in RECT, it's
much easier to modify them using WinAPI functions.
Added two macros to get width and height of the rect.
This was off for mpv CLI, but on for libmpv. The motivation behind this
was that it would be confusing for applications if libmpv continued
playback in a severely "degraded" way (without either audio or video),
and that it would be better to fail early.
In reality the behavior was just a confusing difference to mpv CLI, and
has confused actual users as well. Get rid of it.
Not bothering with a version bump, since this is so minor, and it's easy
to ensure compatibility in affected applications by just setting the
option explicitly.
(Also adding the missing next-release-marker in client-api-changes.rst.)
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.
Annoying exception that makes no sense to keep. Normally, users or
client applications will either use --hwdec=auto, or not set the option
at all, which both leads to the expected result.
By default the CreateProcess changes the mouse cursor to
IDC_APPSTARTING. The new flag added to STARTUPINFOEXW prevents
changing the cursor from default arrow on creating a new process.
This commit introduces mp.utils.file_info() for querying information
on file paths, implemented for both Lua and Javascript.
The function takes a file path as an argument and returns a Lua table /
JS object upon success. The table/object will contain the values:
mode, size, atime, mtime, ctime and the convenience booleans is_file, is_dir.
On error, the Lua side will return `nil, error` and the Javascript side
will return `undefined` (and mark the last error).
This feature utilizes the already existing cross-platform `mp_stat()`
function.
The OpenType Font File specification recommends that "Collection fonts
that use CFF or CFF2 outlines should have an .OTC extension." mpv
should accept .otc as a fallback extension for font detection should
the mimetype detection fail.
IETF RFC8081 added the "font" top-level media type,
including font/ttf, font/otf, font/sfnt, and also
font/collection. These font formats are all supported
by mpv/libass but they are not accepted as valid
Matroska mime types. mpv can load them via file extension
and they work as expected, so files using the new types
should not trigger a warning from mpv.
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.
When autoprobing the hwdec interops (which now happens to all compiled
interops if hardware decoding is used), failure to load an interop
should not print an error in the normal case. So hide it.
(We could make the log level conditional on whether autoprobing is used,
but directly loading it without autoprobing is obscure, and most other
interops don't do this either.)
For METHOD_INTERNAL hwdecs (non-copy cases), make sure the VO interops
are always loaded, because those decoders will output hardware pixel
formats, which will need special support in vo_gpu. Otherwise,
initialization will fail, complaining that it can't convert the output
format to something the VO supports.
It seems like there's nothing stopping from sub-demuxers from keeping
packets in the cache, even if it's completely pointless. The top-most
demuxer (demux_timeline) already takes care of caching, so sub-demuxers
only waste space and time with this.
Add a function that can disable the packet cache even at runtime and
after packets are read. (It's not clear whether it really can happen
that packets are read before demux_timeline gets the sub-demuxers, but
there's no reason to make it too fragile.) Call it on all sub-demuxers.
For this to work, it seems we have to move the code for setting the
seekable_cache flag to before demux_timeline is potentially initialized,
because otherwise the cache would be reenabled if the demuxer triggering
timeline support is a timeline segment itself (e.g. ordered chapters).
This fixes missing audio when cycling through audio tracks with anything
that uses nested demuxers, such as demux_timeline, which us used for
EDL, --merge-files, ordered chapters, and youtube-dl pseudo DASH
support. When this bug happened, reenabling an audio track would lead to
silence for the duration of the readahead amount.
The underlying reason is the incorrectly updated buffered range on track
switch. It accidentally included the amount covered by the deselected
stream. But the cause of the observed effect was that demux_timeline
issued a refresh seek to the underlying slave demuxer, which in turn
thought it could do a cache seek, because the seek range still included
everything.
update_stream_selection_state() calls update_seek_ranges() to update the
seek ranges after a track switch. When reenabling the track, ds->eager
was set to false during update_seek_ranges(), which made it think the
stream was sparse, and thus it didn't restrict the current seek range
(making later code think everything was buffered). Fix this by moving
some code, so we first update the ds->eager flag, then the seek ranges.
Also verbose log the low level stream selection calls.
Calling do_deactivate_getch2 before joining the terminal thread could
lead to breakage if the terminal thread got another interation in before
it was signaled to stop.
This also addresses a minor error with the order in which things are
initialized - getch2_poll would previously call tcgetpgrp(tty_in) before
tty_in was initialized, which did not lead to broken behavior, but was
not correct either.
Fixes#5195
This implements a poll-compatible interface, backed by select on macOS,
suitable for polling on device files - which are not supported by
macOS's implementation of poll. This is a (long-standing) bug in macOS,
so hopefully we can eventually remove this shim.
'help' is a valid value for a lot of mpv options, such as `hwdec`
or `vo` for printing available values, so this change makes the
output of OPT_CHOICE options like `--video-sync=help` more
consistent by not reporting an error about invalid value 'help'.
update_subtitles() makes sure all subtitle packets at/before the given
PTS have been read and processed. Normally, this function is only called
before sending a frame to the VO. This is too late for vf_sub, which
expects the subtitles to be updated before feeding a frame to the
filters.
Apparently this was specifically a problem for the first frame.
Subsequent frames might have been ok due to general prefetching.
(This will fail anyway, should a filter dare to add an offset to the
timestamps of the filered frames before they pass to vf_sub.)
Fixes#5194.
