Because it's kind of dumb. (But not sure if it was worth the trouble.)
For stream_file.c, we add new explicit fields. The rest are rather
special uses and can be killed by comparing the stream impl. name.
The changes to DVD/BD/CD/TV are entirely untested.
"uncached_stream" is a pretty bad name. It could be mistaken for a
boolean, and then its meaning would be inverted. Rename it.
Also add a "caching" field, which signals that the stream is a cache or
reads from a cache. This is easier to understand and more flexible.
when the color profile was changed it used the right NSScreen but with
the old colorSpace. this was optimised out by a previous commit because
of a wrong assumption. we need to update the screen so we can get the
new colorSpace. this adds a bit of redundancy since on screen change it
will update screen pointer twice.
the problem here is that dropped files can also be treated as
NSURLPboardType instead of just NSFilenamesPboardType. the 'else if'
could never be reached and was dead code.
this basically reverts ed695ce which tried to fix multiple dropped
URLs, or rather files, and moves the filename check infront of the URL
check. the filename path can handle multiple dropped files, whereas the
URL path can only handle one dropped URL. this assumes that only one URL
can be dropped at a time. it also reverts a603543 because it's not
needed any more.
this also fixes a problem where dropped URLs from Chrome don't conform
to the NSURL class and the readObjectsForClasses method always returned
an empty URL.
Fixes#4036
this optimises two things and fix a minor bug.
1. we always updated the display refresh rate on any mode change whether
it was the current screen or not. now we only update the refresh rate
when the mode changed happened on the current screen.
2. the windowDidChangeScreen event doesn't exclusively trigger on screen
changes so we updated the display refresh rate in cases where it wasn't
needed at all. since we manually keep track of the current screen, we
can easily test if the screen really changed.
3. weirdly on initWithContentRect accessing the screen of the window
always returned the main screen instead of the screen the window is
created on. since we already use the window init method with the screen
as argument, overwrite that method instead and use the screen argument.
we are dealing with several problems here, which weren't apparent
because we always initialised a new displaylink for the display refresh
rate retrieval, previously to commit 449eb20 and bug 9490b62.
just changing the display with CVDisplayLinkSetCurrentCGDisplay
can cause inconsistent refresh rates and discontinuity in timestamps.
this can either lead to bogus values for the Actual display refresh rate
or retrieving the refresh rate of the previous display if we immediately
try to get a new value. since the Actual refresh rate is computed i
assume that it at least needs one refresh period to actual return
something useful.
furthermore when changing the screen and updating the displaylink, it
seems that the retrieved refresh rates for the screen mpv wasn't opened
on are being estimated in a sub-optimal way. as an example, when moving
my window to my second screen the Actual refresh rate was always a
constant 60Hz, even though it is supposed to fluctuate a little bit.
though if mpv was started on the secondary screen the Actual refresh
rate fluctuated around 59.94Hz like expected. in that case my primary
screen always reported a constant 60Hz instead.
for the first problem we moved the actual retrieval of the refresh rate
to the very last moment when mpv actual requests a new value and not
when the refresh rate changed. we only update the displaylink itself
when a possible refresh rate change is detected. this gives the
displaylink some time to calculate the new refresh rate. for the second
problem, instead of setting the new display we completely uninitialise
the old dislaylink and create a new one for the new screen. this gives
us properly estimated refresh rates.
additionally we also optimised the display refresh rate fallback
heuristic. it will never be 0 anymore and we prevent it from returning
bogus values with a simple threshold for the difference of the Actual
and Nominal refresh rate.
several unicode characters can be encoded in two different ways, either
in a precomposed (NFC) or decomposed (NFD) representation. everywhere
besides on macOS, specifically HFS+, precomposed strings are being used.
furthermore on macOS we can get either precomposed or decomposed
strings, for example when not HFS+ formatted volumes are used. that can
be the case for network mounted devices (SMB, NFS) or optical/removable
devices (UDF). this can lead to an inequality of actual equal strings,
which can happen when comparing strings from different sources, like the
command line or filesystem. this makes it mainly a problem on macOS
systems.
one case that can potential break is the sub-auto option. to prevent
that we convert the search string as well as the string we search in to
the same normalised representation, specifically we use the decomposed
form which is used anywhere else.
this could potentially be a problem on other platforms too, though the
potential of occurring is very minor. for those platforms we don't
convert anything and just fallback to the input.
Fixes#4016
This should allow us to create the device in situations when
Direct3DCreate9 normally fails, for example if no user is logged in.
While the later use-case is not very interesting, I hope it to work in
some other situations as well, for example while certain drivers are in
exclusive full screen mode.
This is available since Windows 7, so I'm removing the old call
completely.
This could potentially have caused fun crashes if the --tv-channels
option was used, and something more advanced than tv:// was used to open
it. (This code is still untested.)
To make it easier for the eyes, multi line subtitles should
be left justified (for most languages).
This adds an option to define how subtitles are to be justified
inpendently of how they are aligned.
Also add option to enable --sub-justify to be applied on ASS subtitles.
Requested. Supposedly "scenarist closed captions".
(The list of getting quite full. But it's probably still better than
trying to probe the files by contents, because the external subtitle
loader code will initially look at _all_ files in the same directory as
the main file.)
TOOLS/matroska.py can be used stand-alone for dumping Matroska file
contents. Fix some related issues.
Elements were treated as unknown if the element hex ID contained
uppercase characters.
Unknown elements stopped parsing. This was intentional, but I don't
really see any reason for it.
Dumping with Python 2 is broken. I don't care, but everytime I hit this,
I find myself trying to find out why. So make it error out explicitly.
Fixes seeking with:
https://bugs.chromium.org/p/chromium/issues/detail?id=497889
Haali also ignores the element's contents, and interprets its presence
as the block not being a keyframe. FFmpeg is going to have an equivalent
change.
I don't know yet whether the affected sample is valid - a reference
timestamp of 0 doesn't make too much sense to me.
video/out/opengl/hwdec_cuda.c is enabled with cuda-hwaccel. But it makes
only sense to build if GL is enabled, and in fact it fails to link
without GL as it calls a specific GL helper function.
In theory it would be perfectly possible to use cuda-copy with GL
disabled. But I'm not bothering with the complexity.
setting a window level other than NSNormalWindowLevel always sets
NSWindowCollectionBehaviorTransient, which prevents certain things to
work properly. examples are automatic switching to the active Space when
mpv is made active and (de-)miniaturizing. latter always lead to a
vanishing window.

Microsoft example code often uses a SAFE_RELEASE macro like the one in
the above link. This makes it easier to avoid errors when releasing COM
interfaces. It also reduces noise in COM-heavy code.
ao_wasapi.h also had a macro called SAFE_RELEASE, though unlike the
version above, its SAFE_RELEASE macro accepted a second parameter which
allowed it to destroy arbitrary objects other than just COM interfaces.
This renames ao_wasapi's SAFE_RELEASE to SAFE_DESTROY, which should more
accurately reflect what it does and prevent confusion with the Microsoft
version.
Useful for distinguishing bit depth when hardware decoding. (To the
degree it's useful to show it at all. This just brings the hardware
decoding case on the same level of showing information as the software
decode call.)
The lock was disabled recently. This commit gets rid of the dummied out
calls. The main reason for removing it is that there is no apparent need
for it anymore, and the new FFmpeg vaapi code does not use or provide
such a lock (there are some places which we cannot control and which do
vaapi API calls, like frame destructors).
When mpv is being linked against static libraries which have shared
libraries as dependencies, linker will throw error because pkg-config
with --static flag will return shared libraries which will be placed
under the -Wl,-Bstatic section, while pkg-config without --static flag
will omit the private libraries required to link the static library.
With this function users can modify the wscript to insert the dependencies
when necessary. For example, linking FFmpeg with shared OpenSSL and zlib:
'func': check_pkg_config_mixed(['crypto','ssl','z'], 'libavcodec')
Upstream provides pkgconfig files for quite some time now [1,2].
Use them to determine the required flags instead of hard coding.
This makes cross-compilation easy, which I dare to say is important for
many raspberry-pi users. This also prevents picking libEGL and libGLESv2
from mesa when they are present, which can happen with the current code.
Good distros should put these pkgconfig files into default pkg-config
search path or populate PKG_CONFIG_PATH for users. However, be nice to
everybody and manually look into '/opt/vc/lib/pkgconfig' just in case.
Hence the PKG_CONFIG_PATH mangling.

In a first pass, we check whether libavcodec is present.
Then we try to compile a snippet and check for FFmpeg vs. Libav. (This
could probably also be done by somehow checking the pkgconfig version.
But pkg-config can't deal with that idiotic FFmpeg idea that a micro
version number >= 100 identifies FFmpeg vs. Libav.)
After that we check the project-specific version numbers. This means it
can no longer happen that we accidentally allow older, unsupported
versions of FFmpeg, just because the Libav version numbers are somehow
this way.
Also drop the resampler checks. We hardcode which resampler to each with
each project. A user can no longer force use of libavresample with
FFmpeg.
The correctness of the stdatomic.h emulation via the __sync builtins is
questionable, and we've been relying on exact stdatomic semantics for a
while, so just get rid of it. Compilers which support __sync but not
stdatomic.h will use to the slow mutex fallback.
Not sure about the __atomic builtins. It doesn't seem to harm either, so
leave it for now.
This is almost cosmetic, but removes the duplicated EOF-setting.
Somewhat oddly, this will enter the reconnect path and exit it
immediately again - should be fine.
Commit 7be495b3 added the cancellation test, but forgot to set the eof
flag. This could lead to demux_mkv.c not terminating if the stream was
cancelled in some code paths.
This function is what is supposed to set the EOF flag in the first
place, so just add the missing code.
A hacky, convoluted, half-working mess that attempts to cut off overlong
playlists.
It does so by relying on the ASS formatting rule that the font size is
specified in the virtual PlayResY resolution. This means we can
(normally) easily tell how many lines fit on the screen. On the other
hand, this does not work if the text is wrapped.
This as a kludge until a Better™ solution is available.
Apparently this is the maximum that can be preserved. There is also
something about the decoder being able only to use 3 frames at a time,
and I'm assuming these are part of the 8 frames.
It was basically inverted. Not sure how this even happened. Hopefully
it's more an "I don't know what I was doing" instead of an "I don't know
what I am doing" case.
When playing with VOs which do not provide mp_hwdec_ctx, vf->hwdec_devs
will remain NULL. This would make it crash on hwdec_devices_get_first(),
even if no hardware decoding or filters using hardware decoding were
involved.
Fixes#4064.
avcodec_parameters_to_context() overwrites codec_type and codec_id. But
we already set these by passing the selected AVCodec to
avcodec_alloc_context3(). It's entirely possible that at least codec_id
is different when forcing codecs with --ad/--vd. It's probably better
not to cause confusion by overwriting them. It might even trigger
undefined behavior in libavcodec (how it behaves or whether codec_id is
supposed to be strictly set is unknown, though).
This can be useful in other contexts.
Note that we end up setting AVCodecContext.width/height instead of
coded_width/coded_height now. AVCodecParameters can't set coded_width,
but this is probably more correct anyway.
