Commit acb40644 fixed video with unaligned luma/chroma sizes. It
attempted to disable the fix for videos where it effectively does
nothing (just some minor performance paranoia), but this check was
broken - fix it by not duplicating the logic for this.
PNG uses a different component order from GL_RGBA, so we upload the
surface using the "wrong" order, and then fix it in the shader. This
breaks if a sRGB texture (GL_SRGB) is used: the hardware will not touch
the alpha channel, which means that the B component is not adjusted,
leading to incorrect output.
Just remove the use of sRGB textures completely. It might lead to a
slight slow down when playing RGB with color management enabled, but
with this combination of obscure use case with minor performance impact
it's not a meaningful disadvantage.
Unfortunately this also means that alpha is handled incorrectly with our
own color management, but alpha isn't so important and can be fixed
later. (0.0 and 1.0 are unchanged by the transfer function, so it
"mostly" works.)
Fixes#1530.
This was apparently useful for correct interlaced scaling (although I
don't know anyone who used this). It was rarely used (if at all), had an
inconvenient output format (packed YUV), and now has a better solution
in libavfilter (using the libavfilter "scale" filter via vf_lavfi).
There is no reason to keep this filter any longer.
It's entirely useless. I left it in for a while, because the analog TV
code had a transitional bug that could switch chroma planes, but it was
fixed long ago. It's also available in libavfilter.
Apparently it was completely broken and essentially did nothing. This
was broken sometime in early mpv or mplayer2 times.
Get rid of it. If you _really_ need it, wait until FFmpeg ports it from
MPlayer, which will happen very soon.
This deals with subsampled YUV video that has odd sizes, for example a
5x5 image with 4:2:0 subsampling.
It would be easy to handle if we actually passed separate texture
coordinates for each plane to the shader, but as of now the luma
coordinates are implicitly rescaled to chroma one. If luma and chroma
sizes don't match up, and this is not handled, you'd get a chroma shift
by 1 pixel.
The existing hack worked, but broke separable scaling. This was exposed
by a recent commit which switched to GL_NEAREST sampling for FBOs. The
rendering was accidentally scaled by 1 pixel, because the FBO size used
the original video size, while textures_sizes[0] was set to the padded
texture size (i.e. one pixel larger).
It could be fixed by setting the padded texture size only on the first
shader. But somehow that is annoying, so do something else. Don't pad
textures anymore, and rescale the chroma coordinates in the shader
instead.
Seems like this somehow doesn't work with rectangle textures (and
introduces a chroma shift), but since it's only used when doing VDA
hardware decoding, and the bug occurs only with unaligned video sizes, I
don't care much.
Fixes#1523.
If a file is unseekable (consider e.g. a http server without resume
functionality), but the stream cache is active, the player will enable
seeking anyway. Until know, client API user couldn't know that this
happens, and it has implications on how well seeking will work. So add a
property which exports whether this situation applies.
Fixes#1522.
This was subtly broken by commit a937ba20. Instead of framestepping over
the timeline segment boundary, it would just unpause playback, because
seeking now resets mpctx->step_frames. This was especially apparent when
doing something like "mpv *.jpg --merge-files".
Fix by restoring the step_frames field specifically if the seek is done
for switching segment boundaries. Hopefully the number fields which need
such an exception on seeking won't grow and turn this code into a mess.
With mf://, rather long frame durations are common. By default, one
frame takes 1 second. This causes the if branch changed with this commit
to always being taken, which in turn leads to the player not being woken
up correctly. (As a consequence, it "freezes" by waiting for events that
never come, and moving the mouse cursor over the window will wake it up
again and advance video.)
Obviously, the code should account for how long the video frame takes.
The code is probably still not fully correct, but for now this fixes the
issue at hand.
Fixes#1521.
Make the default value part of the option metadata, instead of doing
this in the screenshot code. Makes more sense with --list-options and
the command.c option metadata properties.
This allows getting the log at all with --no-terminal and without having
to retrieve log messages manually with the client API. The log level is
hardcoded to -v. A higher log level would lead to too much log output
(huge file sizes and latency issues due to waiting on the disk), and
isn't too useful in general anyway. For debugging, the terminal can be
used instead.
The previous default ("no") seemed to be equivalent to "min" in practice
(though it might depend on the website, which is even worse).
Better just select the best stream by default.
Apparently broken files are popular enough that this is still needed.
It's relatively often asked on the IRC channel, and I also found it on
the archwiki mpv page.
The list of aspect ratios is taken from the archwiki page, with "16:10"
removed (because I doubt there are actually files with this aspect
ratio).
This queries the _ICC_PROFILE property on the root window. It also tries
to reload the ICC when it changes, or if the mpv window changes the
monitor. (If multiple monitors are covered, mpv will randomly select one
of them.)
The official spec is a dead link on freedesktop.org, so don't blame me
for any bugs.
Note that this assumes that Xinerama screen numbers match the way mpv
enumerates the xrandr monitors. Although there is some chance that this
matches, it most likely doesn't, and we actually have to do complicated
things to map the screen numbers. If it turns out that this is required,
I will fix it as soon as someone with a suitable setup for testing the
fix reports it.
Merge update_icc_profile() into get_and_update_icc_profile() - there's
no reason anymore to keep them separate. The former is only called by
the latter, and the separation of responsibilities between them is
blurry a best.
Query the ICC profile only if the corresponding feature is actually
enabled. Additionally, change the error behavior of this code. Make
loading failure non-fatal, and distinguish between runtime error and
unimplemented functionality.
Fix a memory leak in gl_lcms.c (although the changes in vo_opengl.c
already take care of this, it's just logical and cleaner).
Seems like several people agree that it's a good filter for downscaling.
Setting this option by default may also prevent people from accidentally
using an unsuitable filter for downscaling by setting "scale" and
without being aware of the impliciations (maybe). On the other hand,
this change is not strictly backwards compatible for the same reasons.
Also, allow disabling this option with scale-down="" (before this, not
setting it was the only way to do this - not possible anymore if it's
set by default). This is what the change in handle_scaler_opt() does.
Somehow, the default radius for filters with variable radius was set in
mp_init_filter(). gl_video.c used NAN as default value for the radius,
which would make the filter use the default radius. Simplify this, and
set the default radius directly in the gl_video options. It also makes
the options easier to understand, because the default value listed in
--vo=opengl:help actually shows the default value.
Remove the function can_use_filter_kernel(), because it doesn't set a
radius if none is set. The function is worthless anyway (something about
making filter_kernels.c reusable to other VOs, and trying to deal with
the possibility that it could provide filters not supported by
vo_opengl.)
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.
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.
For some sites, youtube-dl sends a special user-agent. If we don't send
the same user-agent, the server will reject mpv's connection attempt.
This was observed with trailers.apple.com. Fix it by forcing the
user-agent youtube-dl uses.
Some sites set cookies when doing a website access, and require the
client to provide these cookies when downloading the actual media. This
is needed at least by nicovideo.jp. Fix by adding youtube-dl's cookies
to our request headers.
Both of these require a very recent youtube-dl version (youtube-dl added
the necessary headers a few hours ago). The script still works with
older youtube-dl versions, though.
This was previously done in common code but now it's left to backends. Also
remove the GL4 stuff since requesting a 3_2_Core context creates a 4.1 context
here (wtf).
Use different VOCTRLs for "window" and normal screenshot modes. The
normal one will probably be removed, and replaced by generic code in
vo.c, and this commit is preparation for this. (Doing it the other way
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.)
New command `mouse <x> <y> [<button> [single|double]]` is introduced.
This will update mouse position with given coordinate (`<x>`, `<y>`),
and additionally, send single-click or double-click event if `<button>`
is given.
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.
Repurpose demuxer->filetype for this. It used to be used to print a
human readable format description; change it to a symbolic format name
and export it as property.
Unfortunately, libavformat has its own weird conventions, which are
reflected through the new property, e.g. the .mp4 case mentioned in the
manpage.
Fixes#1504.
The symlink trick made waf go crazy (deleting source files, getting
tangled up in infinite recursion... I wish I was joking). This means we
still can't build the client API examples in a reasonable way using the
include files of the local repository (instead of globally installed
headers). Not building them at all is better than deleting source files.
Instead, provide some manual instructions how to build each example
(except for the Qt examples, which provide qmake project files).
