Fixes theoretical lock-order issues found by Coverity. Calling these
inside the log is unnecessary anyway, because they have their own
locking, and because mpv_detach_destroy() needs to be called by someone
who has exclusive access to the mpv_handle (it's basically a destructor
function). The lock order issues comes from the fact that they call back
into the client API implementation to broadcast events and such.
Includes hls, mp4, mkv by default. This also avoids stupid things like
decoding at least 1 video frame per stream in the demuxer.
This also add --demuxer-lavf-probe-info to give finer control over what
happens.
fffab30 introduced a small regression where the cursor couldn't be
unhidden after refocusing. the problem is that no mouseUp event was
reported in our events_view. work around this with a separate event
monitor. this also fixes another regression when the window is being
dragged from the title bar.
#4174
This was added for A-B loops, but it looks like commit a1dec6f5 made
this code unnecessary. Remove it, because it has the annoying
side-effect of blocking playback stop when seeking past the end.
This fixes a race condition created by the previous commit, and possibly
others. Sometimes interpolated frames weren't redrawn as uninterpolated
ones.
The problem is that redrawing/drawing a frame can't reset the VO
want_redraw flags, because logically these have to happen after the core
acknowledged and explicitly reissued a redraw. The core needs to be
involved because the OSD text and drawings could depend on the playback
or window state.
Change it such that it always goes through the core.
Also, VOs inconsistently called vo_wakeup() when setting want_redraw,
which is also taken care of by this commit.
When pausing, we sent BOCTRL_PAUSE and VOCTRL_RESTORE_SCREENSAVER. These
essentially wait until the video frame has been rendered. This is a
problem with the opengl-cb, if GL rendering is done in the same thread
as libmpv uses. Unfortunately, it's allowed to use opengl-cb this way.
Logically speaking, it's a deadlock situation, which is resolved with a
timeout. This can lead to quite ugly effects, like the on-pause frame
not being rendered until the timeout has passed. It has been interpreted
as video continuing to play.
Resolve this by simply not blocking on pause. Make the screensaver
controls async, and handle sending VOCTRL_PAUSE in the VO thread.
(All this could be avoided by redoing the internal VO API.)
Also see #4152.
If imgfmt is a hwaccel format, hw_subfmt will contain the CPU equivalent
of the data stored in the hw frames.
Strictly speaking, not doing this was a bug, but since hwaccel formats
were tagged with MP_IMGFLAG_YUV, it didn't have much of an impact.
For example, previously, --audio-device='alsa/' would provide ao->device="" to
the alsa driver in spite of the fact that this is an already parsed option. To
avoid requiring a check of ao->device[0] in every driver, make sure this never
happens.
even though the mouse doesn’t move relative to the window itself, when
the window is being dragged, some outliers are still reported and
trigger the OSC.
fixes the case when mpv is opened and the cursor is within the window
bounds without moving the mouse. previously the window could only be
dragged around after the first mouse movement.
Currently, tracks have always associated streams, so there can't be a
NULL dereference on the next line. But all the code is written with the
possibility in mind that we might want tracks without streams, so make
it consistent.
Found by coverity.
Not so important by itself, but important for when we replace the vf
libavfilter wrapper with the common implementation. (Which will
hopefully happen, but not too soon.)
Preparation for enabling hw filters. mp_image_params can't have an
AVHWFramesContext reference (because it can't hold any allocations, and
isn't meant to hold "active" data in the first place.
So just use a mp_image. It has all real data removed, because that would
essentially leak 1 frame once the decoder or renderer don't need it
anymore.
Not needed under any circumstances. While the Windows ones export
functions to which we must link, these functions are always available,
even if libavcodec was compiled with D3D disabled.
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
even before the recent refactor the cursor was hidden when moving it to
the top of the screen in fullscreen and placing it on top of the now
visible menu bar.
we need to know when the menu bar is hidden so we don’t create a
‘dead zone’ at the top of the screen where the cursor can’t be hidden.
to determine when the menu bar is visible, and with that the title bar,
we get the height of the menu bar. the height is always 0 when hidden.
furthermore there is no way to get the title bar directly and with that
its height. so we calculate the frame rect of a NSWindowStyleMaskTitled
window from a CGRectZero content frame. the resulting height is the
height of a title bar.
with that we can exclude the top area for the cursor hiding and can be
certain when the menu bar is not hidden.
the cursor couldn’t be hidden when the cursor was at the same position
as the Dock, even if the cursor was next to it. this is especially
annoying in fullscreen since the Dock isn’t actually hidden but is still
reported as being visible. this basically made the part of the screen,
where the Dock resides, a ‘dead zone’. so instead of using the
visibleFrame we will just use the normal frame. there is no problem at
the top area of the screen, since a window can’t be placed above the
menu bar and in fullscreen the menu bar is always reported as not being
on screen.
i suspect this was done so the cursor wasn’t hidden when the it was
placed above the Dock when windowed. with the recent refactor this is
not needed any more.
we can simplify the code because we don't need to change the bool
pointer we were given by the VOCTRL_SET_CURSOR_VISIBILITY event. i
assume this was done to work around some bugs previously to the recent
cursor refactor. i kept that because i thought it was necessary, which
wasn't in the end. after the refactor it only caused some weirdnesses i
tried to work around. without it we can get rid of some special cases
and simplify the code quite a bit.
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.
We can drop the custom table.
For some reason, the interop does not accept GL_RGB_RAW_422_APPLE as
internal format for GL_RGB_422_APPLE, so switch the format table to use
GL_RGB (this way both interop and real textures work the same).
Another victim of the apparent requirement of exactly matching texture
formats is kCVPixelFormatType_32BGRA. vo_opengl wants to handle this as
normal RGBA texture, with a swizzle applied in the shader.
CGLTexImageIOSurface2D() rejects this, because it wants the exact
internal format. Just drop the format, because it's useless anyway.
(Maybe this is a bit too fragile...)
All supported pixel formats have a specific "mapping" of CPU data to
textures. This function determines the number and the formats of these
textures. Moving it to a helper will be useful for some hardware decode
interop backends, since they all need similar things.
GL_LUMINANCE_ALPHA is the only reason why per-plane swizzles exist.
Remove per-plane swizzles (again), and regrettably handle them as
special cases (again). Carry along the logical texture format (called
gl_format in some parts of the code, including the new one).
We also don't need a use_integer flag, since the new gl_format member
implies whether it's an integer texture. (Yes, the there are separate
logical GL formats for integer textures. This aspect of the OpenGL API
is hysteric at best.)
This should change nothing about actual rendering logic and GL API
usage.
Originally, there was probably some sort of intention to restrict it to
formats supported by the interop, or something. But in the end it was
overcomplicated nonsense.
In the future, we could use mp_hwdec_ctx.supported_formats or other
mechanisms to handle this in a better way.
mp_hwdec_ctx.ctx is not set to a dummy pointer - hwdec_devices_load() is
only used to detect whether to vo_opengl interop is present, and the
common hwdec code expects that the .ctx field is not NULL.
This also changes videotoolbox-copy to use --videotoolbox-format,
instead of the FFmpeg-set default.
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.
