wm4 1a8af89b7d vo: fix mismatching types in pointer operation
run_control() dereferences an uint32_t as int. Whether this is allowed
depends on what uint32_t is typedefed to (dereferencing an unsigned int
as int should be fine). Fix it by always using int. The uint32_t type
never really made sense.

wm4 32cc190a55 player: fix display-sync timing if audio take long on resume
In display-sync mode, the very first video frame is idiotically fully
timed, even though audio has not been synced yet at this point, and the
video frame is more like a "preview" frame. But since it's fully timed,
an underflow is detected if audio takes longer than the display time of
the frame (we send the second frame only after audio is done).

The timing code will try to compensate for the determined desync, but it
really shouldn't. So explicitly discard the timing info in this specific
case. On the other hand, if the first frame still hasn't finished
display, we can pretend everything is ok.

This is a hack - ideally, we either would send a frame without timing
info (and then send it again or so when playback starts properly), or we
would add real pause support to the VO, and pause it during syncing.

wm4 bd9c0a10e5 vo_opengl: allow backends to provide callbacks for custom event loops
Until now, this has been either handled over vo.event_fd (which should
go away), or by putting event handling on a separate thread. The
backends which do the latter do it for a reason and won't need this, but
X11 and Wayland will, in order to get rid of event_fd.

Niklas Haas 393a069112 vo_opengl: expose performance timers as properties
This is plumbed through a new VOCTRL, VOCTRL_PERFORMANCE_DATA, and
exposed as properties render-time-last, render-time-avg etc.

All of these numbers are in microseconds, which gives a good precision
range when just outputting them via show-text. (Lua scripts can
obviously still do their own formatting etc.)

wm4 c1cb04b6a3 vo_opengl: apply vo-cmdline command incrementally
Instead of implicitly resetting the options to defaults and then
applying the options, they're always applied on top of the current
options (in the same way adding new options to the CLI command line
will).

This does not apply to vo_opengl_cb, because that has an even worse mess
which I refuse to deal with.

wm4 46fff8d31a video: refactor how VO exports hwdec device handles
The main change is with video/hwdec.h. mp_hwdec_info is made opaque (and
renamed to mp_hwdec_devices). Its accessors are mainly thread-safe (or
documented where not), which makes the whole thing saner and cleaner. In
particular, thread-safety rules become less subtle and more obvious.

The new internal API makes it easier to support multiple OpenGL interop
backends. (Although this is not done yet, and it's not clear whether it
ever will.)

This also removes all the API-specific fields from mp_hwdec_ctx and
replaces them with a "ctx" field. For d3d in particular, we drop the
mp_d3d_ctx struct completely, and pass the interfaces directly.

Remove the emulation checks from vaapi.c and vdpau.c; they are
pointless, and the checks that matter are done on the VO layer.

The d3d hardware decoders might slightly change behavior: dxva2-copy
will not use the VO device anymore if the VO supports proper interop.
This pretty much assumes that any in such cases the VO will not use any
form of exclusive mode, which makes using the VO device in copy mode
unnecessary.

This is a big refactor. Some things may be untested and could be broken.

maniak1349 7d9eab15f0 win32: make taskbar progress indication optional
Add --taskbar-progress command line option and property which controls taskbar
progress indication rendering in Windows 7+. This option is on by default and
can be toggled during playback.

This option does not affect the creation process of ITaskbarList3. When the
option is turned off the progress bar is just hidden with TBPF_NOPROGRESS.

Closes #2535

wm4 9db50c6760 vo: get rid of vo_get_window_title()
It always was a weird artifact - VOCTRLs are meant _not_ to require
special handling in the code that passes them through (like in vo.c).
Removing it is also interesting to further reduce the dependency of
backends on struct vo. Just get rid of it.

Removing it is somewhat inconvenient, because in many situations the UI
window is created after the first VOCTRL_UPDATE_WINDOW_TITLE. This means
these backends have to store it in a new field in their own context.

wm4 318e9801f2 vo_opengl: fix interpolation with display-sync
At least I hope so.

Deriving the duration from the pts was not really correct. It doesn't
include speed adjustments, and becomes completely wrong of the user e.g.
changes the playback speed by a huge amount. Pass through the accurate
duration value by adding a new vo_frame field.

The value for vsync_offset was not correct either. We don't need the
error for the next frame, but the error for the current one. This wasn't
noticed because it makes no difference in symmetric cases, like 24 fps
on 60 Hz.

I'm still not entirely confident in the correctness of this, but it sure
is an improvement.

Also, remove the MP_STATS() calls - they're not really useful to debug
anything anymore.

wm4 7023c383b2 vo: change vo_frame field units
This was just converting back and forth between int64_t/microseconds and
double/seconds. Remove this stupidity. The pts/duration fields are still
in microseconds, but they have no meaning in the display-sync case (also
drop printing the pts field from opengl/video.c - it's always 0).

wm4 1fe64c61be vo_opengl: disable interpolation without display-sync

wm4 772961f0ce command, vo: add estimated-display-fps property
This is simply the average refresh rate. Including "bad" samples is
actually an advantage, because the property exists only for
informational purposes, and will reflect problems such as the driver
skipping a vsync.

Also export the standard deviation of the vsync frame duration
(normalized to the range 0-1) as vsync-jitter property.

wm4 2e401201ad vo: remove VOCTRL_GET_RECENT_FLIP_TIME
It doesn't have any real purpose anymore. Up until now, it was still
implemented by vo_wayland, but since we changed how the frame callbacks
work, even that appears to be pointless.

Originally, the plan was to somehow extend this mechanism to all
backends and to magically fix frame scheduling, but since we can't hope
for proper mechanisms even on wayland, this idea looks way less
interesting.

wm4 a790009a63 player: account for minor VO underruns
If the player sends a frame with duration==0 to the VO, it can trivially
underrun. Don't panic, but keep the correct time.

Also, returning the absolute time from vo_get_next_frame_start_time()
just to turn it into a float with relative time was silly. Rename it and
make it return what the caller needs.

wm4 f0feea5591 command: rename vo-missed-frame-count property
"Missed" implies the frame was dropped, but what really happens is that
the following frame will be shown later than intended (due to the
current frame skipping a vsync).

(As of this commit, this property is still inactive and always
returns 0. See git blame for details.)

wm4 e6a395c297 vo_opengl, vo_opengl_cb: drop unneeded vo_frame fields
next_vsync/prev_vsync was only used to retrieve the vsync duration. We
can get this in a simpler way.

This also removes the vsync duration estimation from vo_opengl_cb.c,
which is probably worthless anyway. (And once interpolation is made
display-sync only, this won't matter at all.)

wm4 291f301c10 video/out: remove an unused parameter
This parameter has been unused for years (the last flag was removed in
commit d658b115). Get rid of it.

This affects the general VO API, as well as the vo_opengl backend API,
so it touches a lot of files.

The VOFLAGs are still used to control OpenGL context creation, so move
them to the OpenGL backend code.

wm4 031555fbe6 player: add display sync mode
If this mode is enabled, the player tries to strictly synchronize video
to display refresh. It will adjust playback speed to match the display,
so if you play 23.976 fps video on a 24 Hz screen, playback speed is
increased by approximately 1/1000. Audio wll be resampled to keep up
with playback.

This is different from the default sync mode, which will sync video to
audio, with the consequence that video might skip or repeat a frame once
in a while to make video keep up with audio.

This is still unpolished. There are some major problems as well; in
particular, mkv VFR files won't work well. The reason is that Matroska
is terrible and rounds timestamps to milliseconds. This makes it rather
hard to guess the framerate of a section of video that is playing. We
could probably fix this by just accepting jittery timestamps (instead
of explicitly disabling the sync code in this case), but I'm not ready
to accept such a solution yet.

Another issue is that we are extremely reliant on OS video and audio
APIs working in an expected manner, which of course is not too often
the case. Consequently, the new sync mode is a bit fragile.

wm4 4a1657da01 vo: minor simplification for queue size handling
Instead of calling it "future frames" and adding or subtracting 1 from
it, always call it "requested frames". This simplifies it a bit.

MPContext.next_frames had 2 added to it; this was mainly to ensure a
minimum size of 2. Drop it and assume VO_MAX_REQ_FRAMES is at least 2;
together with the other changes, this can be the exact size of the
array.

wm4 0739cfc209 vo: change internal API for drawing frames
draw_image_timed is renamed to draw_frame. struct frame_timing is
renamed to vo_frame. flip_page_timed is merged into draw_frame (the
additional parameters are part of struct vo_frame). draw_frame also
deprecates VOCTRL_REDRAW_FRAME, and replaces it with a method that
works for both VOs which can cache the current frame, and VOs which
need to redraw it anyway.

This is preparation to making the interpolation and (work in progress)
display sync code saner.

Lots of other refactoring, and also some simplifications.

wm4 c5e3613bba video: pass vsync offset to VO
For now, this is trivial (and actually redundant). The future display
sync code will make better use of it. The main point is that the new
internal API pretty much makes this transparent to the vo_opengl
interpolation code.
2015-07-01 22:37:51 +02:00
wm4 41ad9d8924 video: pass future frames to VO
Now the VO can request a number of future frames with the last parameter
of vo_set_queue_params(). This will be helpful to fix the interpolation
code.

Note that the first frame (after playback start or seeking) will usually
not have any future frames (to make seeking fast). Near the end of the
file, the number of future frames will become lower as well.

wm4 10de9b091a vo_opengl: change user options for requesting GLES
Instead of having separate backends, make use of GLES a flag. This

compatibility either.

wm4 29eb764fe0 cocoa: make live-resizing as fast as before
Interrupt video timing. This means the Cocoa event loop does not have
to up to 2 video frame durations until redrawing the frame finally has
finished.

We abuse the VO event flags for this. Eventually this should use
wait_vo() or so in the video timing wait function, but for now the
interaction this would require with the code of other VOs/backends
would cause too much of a mess.

wm4 e185887ba0 video/out: remove VOFLAG_FLIPPING
I think this used to be quite important, because the ancient VfW support

for quite some time (because VfW decoders were removed, and the --flip
option was dropped too), so get rid of it.

wm4 8f0f73e591 video/out: remove unused colorspace reporting
Rarely used and essentially useless. The only VO for which this was

specific extension for BT.709, whose presence this function essentially

wm4 6de3fe0b34 command: fix display-fps property (again)
This caused complaints because the fps was basically rounded on
microsecond boundaries in the vsync interval (it seemed convenient to

the "display-fps" property return it directly.

wm4 209f8225ed vo: update FPS only on state changes
I'm not comfortable with VOCTRL_GET_DISPLAY_FPS being called every

This requires the VO to set VO_EVENT_WIN_STATE if the FPS could have
changed. At least the X11 backend does this.

wm4 8657b8e1f3 vo: generic redraw support
Usually, a VO must react to VOCTRL_REDRAW_FRAME in order to redraw the
current screen correctly if video is paused (this is done to update
OSD). But if it's not supported, we can just draw the current image
again in the generic vo.c code.

Unfortunately, this turned out pretty useless, because the VOs which
would benefit from this need to redraw even if there is no image, in
order to draw a black screen in --idle --force-window mode. The way
redrawing is handled in the X11 common code and in vo_x11 and vo_xv is
in the way, and I'm not sure what exactly vo_wayland requires. Other VOs
have a non-trivial implementation of VOCTRL_REDRAW_FRAME, which
(probably) makes redrawing slightly more efficient, e.g. by skipping
texture upload. So for now, no VO uses this new functionality, but since
it's trivial, commit it anyway.

The vo_driver->untimed case is for forcibly disabling redraw for vo_lavc
and vo_image always.

wm4 2858232220 vo: simplify VOs by adding generic screenshot support
At the time screenshot support was added, images weren't refcounted yet,
so screenshots required specialized implementations in the VOs. But now
we can handle these things much simpler. Also see commit 5bb24980.

If there are VOs in the future which can't do this (e.g. they need to
write to the image passed to vo_driver->draw_image), this still could be
disabled on a per-VO basis etc., so we lose no potential performance
advantages.

around would be slightly simpler, but I haven't decided yet about the
second one, and touching every VO is needed anyway in order to remove
the unneeded crap. E.g. has_osd has been unused for a long time.)

wm4 a0a40eb287 vo: fix disabling/enabling smoothmotion at runtime
vo.c queried the VO at initialization whether it wants to be updated on
every display frame, or every video frame. If the smoothmotion option
was changed at runtime, the rendering mode in vo.c wasn't updated.

Just let vo_opengl set the mode directly. Abuse the existing
vo_set_flip_queue_offset() function for this.

Also add a comment suggesting the use of --display-fps to the manpage,
which doesn't have anything to do with the rest of this commit, but is
important to make smoothmotion run well.
2015-01-23 20:56:25 +01:00
Stefano Pigozzi c29ab5a46b vo_opengl: add smoothmotion frame blending
SmoothMotion is a way to time and blend frames made popular by MadVR. It's
intended behaviour is to remove stuttering caused by mismatches between the
display refresh rate and the video fps, while preserving the video's original
artistic qualities (no soap opera effect). It's supposed to make 24fps video
playback on 60hz monitors as close as possible to a 24hz monitor.

Instead of drawing a frame once once it's pts has passed the vsync time, we
redraw at the display refresh rate, and if we detect the vsync is between two
frames we interpolated them (depending on their position relative to the vsync).
We actually interpolate as few frames as possible to avoid a blur effect as
much as possible. For example, if we were to play back a 1fps video on a 60hz
monitor, we would blend at most on 1 vsync for each frame (while the other 59
vsyncs would be rendered as is).

Frame interpolation is always done before scaling and in linear light when
possible (an ICC profile is used, or :srgb is used).

wm4 a1ed13869c video: remove vfcap.h
And remove all uses of the VFCAP_CSP_SUPPORTED* constants. This is
supposed to reduce conversions if many filters are used (with many
incompatible pixel formats), and also for preferring the VO's natively
supported pixel formats (as opposed to conversion).

This is worthless by now. Not only do the main VOs not use software
conversion, but also the way vf_lavfi and libavfilter work mostly break
the way the old MPlayer mechanism worked. Other important filters like
vf_vapoursynth do not support "proper" format negotation either.

Part of this was already removed with the vf_scale cleanup from today.

While I'm touching every single VO, also fix the query_format argument
(it's not a FourCC anymore).

in advance on all VOs.

wm4 fb855b8659 client API: expose OpenGL renderer
This adds API to libmpv that lets host applications use the mpv opengl
renderer. This is a more flexible (and possibly more portable) option to
foreign window embedding (via --wid).

This assumes that methods like context sharing and multithreaded OpenGL
rendering are infeasible, and that a way is needed to integrate it with
an application that uses a single thread to render everything.

Add an example that does this with QtQuick/qml. The example is
relatively lazy, but still shows how relatively simple the integration
is. The FBO indirection could probably be avoided, but would require
more work (and would probably lead to worse QtQuick integration, because
it would have to ignore transformations like rotation).

Because this makes mpv directly use the host application's OpenGL
context, there is no platform specific code involved in mpv, except
for hw decoding interop.

main.qml is derived from some Qt example.

The following things are still missing:
- a way to do better video timing
- expose GL renderer options, allow changing them at runtime
- support for color equalizer controls
- support for screenshots

wm4 a74a324b98 video: return responsibility of video redraw back to playloop
When the VO was moved it its own thread, responsibility for redrawing
was given to the VO thread itself. So if there was a condition that
indicated that redrawing was required, like expose events or certain
VOCTRLs, the VO thread was redrawing itself.

This worked fine, but there are some corner cases where this works
rather badly. E.g. if I fullscreen the player and hit panscan controls
with mpv's default autorepeat rate, playback stops. This happens because
the VO redraws itself after every panscan change command. Running each
(repeated) command takes so long due to redrawing and (involuntary)
waiting on vsync, that it never leaves the input processing loop while
the key is held down. I suspect that in my case, redrawing in fullscreen
mode just gets slow enough that it takes 2 vsyncs instead of 1 on
average, and the processing time gets larger than the autorepeat delay.

Fix this by taking redraw control from the VO, and instead let the
playloop issue a "real" redraw command to the VO if needed. This
basically reverts redraw handling to what it was before moving the VO to
a thread.

wm4 68b7217d41 vo_vdpau: better integration with the generic framedrop code
vo_vdpau uses its own framedrop code, mostly for historic reasons. It
has some tricky heuristics, of which I'm not sure how they work, or if
they have any effect at all, but in any case, I want to keep this code
for now. One day it might get fully ported to the vo.c framedrop code,
or just removed.

But improve its interaction with the user-visible framedrop controls.
Make --framedrop actually enable and disable the vo_vdpau framedrop
code, and increment the number of dropped frames correctly.

The code path for other VOs should be equivalent. The vo_vdpau behavior
should, except for the improvements mentioned above, be mostly
equivalent as well. One minor change is that frames "shown" during
preemption are always count as dropped.

Remove the statement from the manpage that vo_vdpau is the default; this
hasn't been the case for a while.

wm4 3d968fc620 video: add VOCTRL_GET_RECENT_FLIP_TIME
This could be used by VO implementations to report a recent vsync time
to the generic VO code, which in turn will use it and the display FPS
to estimate at which point in time the next vsync will happen.

wm4 5b64f5ad35 video: take refresh rate changes into account
This works only on X11, and only if the refresh rate changes due to the
window being moved to another screen (detected by us). It doesn't
include system screen reconfiguration yet.

This calls VOCTRL_GET_DISPLAY_FPS on every frame, which makes me uneasy.
It means extra thread communication with the win32 and Cocoa backends.
On the other hand, a frame doesn't happen _that_ often, and the
communication should still be pretty cheap and fast, so it's probably
ok.

Also needs some extra fuzz for vo_vdpau.c, because that does everything
differently.
2014-08-17 02:50:59 +02:00
wm4 543ba6c114 video: add VO framedropping mode
This mostly uses the same idea as with vo_vdpau.c, but much simplified.

On X11, it tries to get the display framerate with XF86VM, and limits
the frequency of new video frames against it. Note that this is an old
extension, and is confirmed not to work correctly with multi-monitor
setups. But we're using it because it was already around (it is also
used by vo_vdpau).

This attempts to predict the next vsync event by using the time of the
last frame and the display FPS. Even if that goes completely wrong,
the results are still relatively good.

On other systems, or if the X11 code doesn't return a display FPS, a
framerate of 1000 is assumed. This is infinite for all practical
purposes, and means that only frames which are definitely too late are
dropped. This probably has worse results, but is still useful.

"--framedrop=yes" is basically replaced with "--framedrop=decoder". The
old framedropping mode is kept around, and should perhaps be improved.
Dropping on the decoder level is still useful if decoding itself is too
slow.

wm4 5ed7bc6321 video: fix and simplify video format changes and last frame display
The previous commit broke these things, and fixing them is separate in
this commit in order to reduce the volume of changes.

Move the image queue from the VO to the playback core. The image queue
is a remnant of the old way how vdpau was implemented, and increasingly
became more and more an artifact. In the end, it did only one thing:
computing the duration of the current frame. This was done by taking the
PTS difference between the current and the future frame. We keep this,
but by moving it out of the VO, we don't have to special-case format
changes anymore. This simplifies the code a lot.

Since we need the queue to compute the duration only, a queue size
larger than 2 makes no sense, and we can hardcode that.

Also change how the last frame is handled. The last frame is a bit of a
problem, because video timing works by showing one frame after another,
which makes it a special case. Make the VO provide a function to notify
us when the frame is done, instead. The frame duration is used for that.

This is not perfect. For example, changing playback speed during the
last frame doesn't update the end time. Pausing will not stop the clock
that times the last frame. But I don't think this matters for such a
corner case.

wm4 df58e82237 video: move display and timing to a separate thread
The VO is run inside its own thread. It also does most of video timing.
The playloop hands the image data and a realtime timestamp to the VO,
and the VO does the rest.

In particular, this allows the playloop to do other things, instead of
blocking for video redraw. But if anything accesses the VO during video
timing, it will block.

This also fixes vo_sdl.c event handling; but that is only a side-effect,
since reimplementing the broken way would require more effort.

Also drop --softsleep. In theory, this option helps if the kernel's
sleeping mechanism is too inaccurate for video timing. In practice, I
haven't ever encountered a situation where it helps, and it just burns
CPU cycles. On the other hand it's probably actively harmful, because
it prevents the libavcodec decoder threads from doing real work.

Side note:

Originally, I intended that multiple frames can be queued to the VO. But
this is not done, due to problems with OSD and other certain features.
OSD in particular is simply designed in a way that it can be neither
timed nor copied, so you do have to render it into the video frame
before you can draw the next frame. (Subtitles have no such restriction.
sd_lavc was even updated to fix this.) It seems the right solution to
queuing multiple VO frames is rendering on VO-backed framebuffers, like
vo_vdpau.c does. This requires VO driver support, and is out of scope
of this commit.

As consequence, the VO has a queue size of 1. The existing video queue
is just needed to compute frame duration, and will be moved out in the
next commit.

wm4 fa34b4920a vdpau: don't upload video images in advance
With software decoding, images were uploaded to vdpau surfaces as they
were queued to the VO. This makes it slightly more complicated
(especially later on), and has no advantages - so stop doing it.

The only reason why this was done explicitly was due to attempts to keep
the code equivalent (instead of risking performance regressions). The
original code did this naturally for certain reasons, but now that we
can measure that it has no advantages and just requires extra code, we
can just drop it.

wm4 89391e7c94 vo: different hack for VOs which need to mangle mouse input

the currently-annoying issue (VO backends needing access to the VO) out
of the way.

wm4 72aac9ae8a video: introduce failure path for image allocations
Until now, failure to allocate image data resulted in a crash (i.e.
abort() was called). This was intentional, because it's pretty silly to
degrade playback, and in almost all situations, the OOM will probably
kill you anyway. (And then there's the standard Linux overcommit
behavior, which also will kill you at some point.)

But I changed my opinion, so here we go. This change does not affect
_all_ memory allocations, just image data. Now in most failure cases,
the output will just be skipped. For video filters, this coincidentally
means that failure is treated as EOF (because the playback core assumes
EOF if nothing comes out of the video filter chain). In other
situations, output might be in some way degraded, like skipping frames,
not scaling OSD, and such.

wm4 f3362e22eb player: remove VO from seeking code path
Until recently, the VO was an unavoidable part of the seeking code path.
This was because vdpau deinterlacing could double the framerate, and hr-
seek and framestepping etc. all had to "see" the additional frames. But
we've removed the frame doubling from the vdpau VO and moved it into a
video filter (vf_vdpaupp), and there's no reason left why the VO should
participate in seeking.

Instead of queuing frames to the VO during seek and skipping them
afterwards, drop the frames early.

This actually might make seeking with vo_vdpau and software decoding
faster, although I haven't measured it.

wm4 6775487a46 video: move video frame queue from vo_vdpau.c to vo.c
Remove the special casing of vo_vdpau vs. other VOs. Replace the
complicated interaction between vo.c and vo_vdpau.c with a simple queue
in vo.c. VOs other than vdpau are handled by setting the length of the
queue to 1 (this is essentially what waiting_mpi was).

Note that vo_vdpau.c seems to have buffered only 1 or 2 frames into the
future, while the remaining 3 or 4 frames were past frames. So the new
code buffers 2 frames (vo_vdpau.c requests this queue length by setting
vo->max_video_queue to 2). It should probably be investigated why
vo_vdpau.c kept so many past frames.

The field vo->redrawing is removed. I'm not really sure what that would
be needed for; it seems pointless.

Future directions include making the interface between playloop and VO
simpler, as well as making rendering a frame a single operation, as
opposed to the weird 3-step sequence of rendering, drawing OSD, and
flipping.

This replaces all tabs in all source files with spaces. The only

automatic, it's possible that some formatting was destroyed (but perhaps
only if it was assuming that the end of a tab does not correspond to
aligning the end to multiples of 8 spaces).

Functionally, nothing should change, except that the window size is
