Seen with a VOD of a recently ended livestream on Youtube.
They seem to use segmented DASH but unlike normal Youtube
segmented DASH, the segments don't seem to need the initialization
segment.
The video actually fails to start to play if the init segment is
prepended with a lot of 'Found duplicated MOOV Atom. Skipped it' errors
popping up.
This fixes a crash when changing channels; previously stream->priv would not
be initialized when dvb_get_state reused the existing state.

Fall back on PATH_DEV_DSP if nothing is set.
This mirrors the behaviour of --audio-device / --alsa-device.
There doesn't appear to be a general way to list devices with oss, so
--audio-device=help doesn't list oss devices except for the default one if the
file exists.
Previously --audio-device was ignored entirely by ao_oss.
fixes#4122
If we have a disconnected output, read data only passively (and don't
cause input to be written). Otherwise, we're in danger of making
libavfilter queue too many frames on other outputs which are connected
to the same input, but don't read as quickly.
Also don't set pad->output_needed in this specific case, because it
would nonsensically make lavfi_process() return true, even if nothing is
going on.
This commit breaks if there is a simple filter chain with a connected
input, but a disconnected output, like
--lavfi-complex='[aid1] copy [ao]'
and the audio output didn't initialize correctly. This will eventually
starve video as the audio packet queue get full (it will print a
warning, and then assume video EOF and exit).
But whatever.
Probably fixes#4118.
This replaces the old backend that exclusively used EGL windowing with
one that can also use ANGLE's ability to render to directly to a
texture. The advantage of this is that it allows mpv to create the swap
chain itself and this allows mpv to use a flip-mode swap chain on a HWND
(which avoids problems with DirectComposition) and to use a longer swap
chain that has six backbuffers by default (which reportedly fixes
problems with rendering 24fps video on 24Hz monitors.)
Also, "screenshot window" should now work on DXGI 1.2 and up (Windows 8
and up.)
We use the metadata provided by youtube-dl to sort-of implement
fragmented DASH streaming.
This is all a bit hacky, but hopefully a makeshift solution until
libavformat has proper mechanisms. (Although in danger of being one
of those temporary hacks that become permanent.)
If used with fuzzy matching, the player tends to pick up random text
files, sometimes with interesting results.
The most interesting interaction is when the user uses
--log-file=something.txt, and mpv tries to open its own log file. It
essentially "freezes" during probing, because every time it reads from
it, it will write some more data, which in turn will cause more data to
be read - until the 2MB max. probing size is slowly reached. This is not
even an obscure corner case, but happened to multiple users.
The .txt extension has been considered a subtitle extension ever since
the code was added to MPlayer's subreader.c, but I'm not seeing many
actual subtitle files with this extension, so just get rid of it.
As the manual entry for --hwdec states that d3d11va and d3d11va-copy require Windows, it can be assumed that it also works for Windows 7. Since it doesn't, according to https://github.com/mpv-player/mpv/issues/3285#issuecomment-228593539, and personal testing, updating the manual accordingly and making the hwdec OS requirements for ANGLE in line with videotoolbox, where OS version is stated.
Instead of enabling it only when a stream-cache is enabled, also try to
enable it independently from that if the demuxer is marked as
is_network.
Also add some code to the EDL code, so EDLs containing network streams
are automatically cached this way.
Extend the OSD info line so that it shows the demuxer cache in this case
(more or less).
I didn't find where or whether options.rst describes how the demuxer
cache is enabled, so no changes there.
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.

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.
