This will catch cases where mpv runs without error, but the
--list-options output isn't what we expect. Otherwise, we'll make a
broken completion file that will result in cryptic errors when pressing
tab, like:
_mpv:18: command not found: *:files:->mfiles
That's been the case for most of the zsh completion issues we've had
reported, that I can remember.
Also make uninitialized variable access fatal so that failures to parse
other options will also make the script die eventually, albeit with a
less nice message.

Useless feature, but I want it.
Won't work on Windows due to missing fnmatch().

--list-protocol was printing a *:// entry, which looked strange at best.
The "*" protocol was used to always match everything, so stream_cb.c
could hook in custom protocols with a prefix chosen by the API user.
Change it instead so that an empty protocol list means "match all",
which also gets rid of the special-cased "*" entry.

This is an awful corner-case party, because we've started to allow the
user to send track-switching related commands before stream selection is
done in the loading stage. If mp_switch_track() is called before this
stream selection, it can behave inconsistently. So if we're in the
pre-loading phase, we must set the stream selection options to get
streams selected later, instead of calling this function. There seem to
be some annoying circumstances that exclude mp_switch_track() from
handling this logic too, so do it at all call-sites.

The nvidia examples use the old (as in CUDA 3.x) interop API which
is deprecated, and I think not even functional on recent versions
of CUDA for windows. As I was following the examples, I used this
old API.
So, let's update to the new API, and hopefully, it'll start working
on windows too.

This has all been made unnecessary recently. The change not to copy the
global option struct in particular can be made because now nothing
accesses the global options anymore in the demux and stream layers.
Some code that was accidentally added/changed in commit 5e30e7a0 is also
removed, because it was simply committed accidentally, and was never
used.

Mostly untested.
This is not compatible. It removes the URL fields for track range and
cdrom speed (what did this even do). The device is not not to be
prefixed with an additional "/" if it's put into the URL. I can't be
bothered to keep these things compatible, just rip your damn CDs
instead.

Said "audio" instead of "video".
|
| |
|
|
|
|
| |
Instead of deselecting the video stream plainly, use the slightly more
robust error_on_track() function. Also give it an error code (although
I'm not sure if this one is confusing, it's better than the one before).

Same deal as with stream_bluray.
Untested because I don't give a fuck about your shitty DVDs.

Uh, what? It wasn't used at all. It was probably accidentally dropped at
one point, or it was never used at all. Whatever, who cares.

Instead, parse manually. This is to get rid of the option API usages,
which seem unnecessary and shoehorned. (Just look at the URL pseudo
parsing and the dumb url_options map. They were pretty much artifacts
from refactoring old mplayer code.)

It was used to determine whether the VO supports VOCTRL_SET_PANSCAN.
With all those changes to property semantics this became unnecessary,
and its only use was dropped at some point.
|
| |
|
|
|
| |
And since there's no proper fine-grained option change notification
mechanism yet, intercept updates to "framedrop" manually.

Just another corner-caseish potential issue. Unlike unreffing the image
manually, unref_current_image() also takes care of properly unmapping
hwdec frames. (The corner-case part of this is that it's probably never
mapped at this point, but it's apparently not entirely guaranteed.)

The " || vimg->mpi" part virtually never seems to trigger, but on the
other hand could possibly create unintended corner cases (for example by
trying to upload a NULL image, which would then be marked as an error
and render a blue screen).
I guess it's a leftover from over times, where a NULL image meant
"redraw the current frame". This is now handled by actually passing
along the current frame.

Nvidia's "NvDecode" API (up until recently called "cuvid" is a cross
platform, but nvidia proprietary API that exposes their hardware
video decoding capabilities. It is analogous to their DXVA or VDPAU
support on Windows or Linux but without using platform specific API
calls.
As a rule, you'd rather use DXVA or VDPAU as these are more mature
and well supported APIs, but on Linux, VDPAU is falling behind the
hardware capabilities, and there's no sign that nvidia are making
the investments to update it.
Most concretely, this means that there is no VP8/9 or HEVC Main10
support in VDPAU. On the other hand, NvDecode does export vp8/9 and
partial support for HEVC Main10 (more on that below).
ffmpeg already has support in the form of the "cuvid" family of
decoders. Due to the design of the API, it is best exposed as a full
decoder rather than an hwaccel. As such, there are decoders like
h264_cuvid, hevc_cuvid, etc.
These decoders support two output paths today - in both cases, NV12
frames are returned, either in CUDA device memory or regular system
memory.
In the case of the system memory path, the decoders can be used
as-is in mpv today with a command line like:
mpv --vd=lavc:h264_cuvid foobar.mp4
Doing this will take advantage of hardware decoding, but the cost
of the memcpy to system memory adds up, especially for high
resolution video (4K etc).
To avoid that, we need an hwdec that takes advantage of CUDA's
OpenGL interop to copy from device memory into OpenGL textures.
That is what this change implements.
The process is relatively simple as only basic device context
aquisition needs to be done by us - the CUDA buffer pool is managed
by the decoder - thankfully.
The hwdec looks a bit like the vdpau interop one - the hwdec
maintains a single set of plane textures and each output frame
is repeatedly mapped into these textures to pass on.
The frames are always in NV12 format, at least until 10bit output
supports emerges.
The only slightly interesting part of the copying process is that
CUDA works by associating PBOs, so we need to define these for
each of the textures.
TODO Items:
* I need to add a download_image function for screenshots. This
would do the same copy to system memory that the decoder's
system memory output does.
* There are items to investigate on the ffmpeg side. There appears
to be a problem with timestamps for some content.
Final note: I mentioned HEVC Main10. While there is no 10bit output
support, NvDecode can return dithered 8bit NV12 so you can take
advantage of the hardware acceleration.
This particular mode requires compiling ffmpeg with a modified
header (or possibly the CUDA 8 RC) and is not upstream in ffmpeg
yet.
Usage:
You will need to specify vo=opengl and hwdec=cuda.
Note that hwdec=auto will probably not work as it will try to use
vdpau first.
mpv --hwdec=cuda --vo=opengl foobar.mp4
If you want to use filters that require frames in system memory,
just use the decoder directly without the hwdec, as documented
above.

This could also trigger in certain other cases, whenever it falls back
to dumb mode.

reinit() will change the image params fields, so give it a copy.
Will fix potential crashes if preemption happens more than once.

This is a bug fix, and the text alignment functionality probably got
lost sometime along the way.
For ASS subtitles, this could have unintended consequences, so it's hard
to get right - thus it's not applied to ASS subtitles.
For other text subtitles, this should be fine, though. It still works on
ASS subtitles as promised by the manpage if --no-sub-ass is used.

The first one is printed even if the user disabled video (or there's no
video), so just remove it. The second one uses deprecated sub-option
syntax, so remove that as well.

The standard header is stdatomic.h, so the extra "s" freaks me out every
time I look at it.

This time it's emulation that's supposed to work (not just dummied out).
Unlike the previous emulation, no mpv code has to be disabled, and
everything should work (albeit possibly a bit slowly). On the other
hand, it's not possible to implement this kind of emulation without
compiler support. We use GNU statement expressions and __typeof__ in
this case.
This code is inactive if stdatomic.h is available.

Actually, only link to a wiki page doing that, because these are too
many options.

Don't access MPOpts directly, and always use the new m_config.h
functions for accessing them in a thread-safe way.
The goal is eventually removing the mpv_global.opts field, and the
demuxer/stream-layer specific hack that copies MPOpts to deal with
thread-safety issues.
This moves around a lot of options. For one, we often change the
physical storage location of options to make them more localized,
but these changes are not user-visible (or should not be). For
shared options on the other hand it's better to do messy direct
access, which is worrying as in that somehow renaming an option
or changing its type would break code reading them manually,
without causing a compilation error.

Since the sub-options have been deprecated very recently, and are
redirected to global options, we don't need to document this change.
|

Use a char array instead of a pointer, which allows using the version
variables in a constant context.

Instead of copying the options around... just don't. video.c now has
full control over when options are updated. (It still gets notified from
outside, but it decides when the updated options are copied: when
m_config_cache_update() is called.) So there's no need for tricky
stuff, and it can be simplified a bit.
Also change lcms.c. We could do it like video.c, and get the options
from the global config store. But it seems simpler to just provide a
pointer to an option struct, which is arbitrarily mutated from the
outside (from the perspective of lcms.c).

Setting --icc-profile had no effect, until a vo_opengl option was
changed at runtime. We must initialize the renderer for the initial
option state too.
For some reason, the ICC profile gets loaded twice. The next commit
happens to fix this.

It has to copy each option, whether it's deprecated or not. This would
print a warning on every deprecated sub-option, even if it's not used.
Yep, this is very stupid.
At least m_config_get_co() gets actually slightly cleaner, because it
separates the search and the deprecation handling.
|
| |
|
|
|
|
|
| |
And introduce a global option which does this. Or more precisely, this
deprecates the global wasapi and coreaudio options, and adds a new one
that merges their functionality. (Due to the way the sub-option
deprecation mechanism works, this is simpler.)
|
| |
|
|
|
| |
We have --audio-device, which can force the device. Also add something
describing to this extent to the manpage.

I decided that it's too much work to convert all the VO/AOs to the new
option system manually at once. So here's a shitty hack instead, which
achieves almost the same thing. (The only user-visible difference is
that e.g. --vo=name:help will list the sub-options normally, instead of
showing them as deprecation placeholders. Also, the sub-option parser
will verify each option normally, instead of deferring to the global
option parser.)
Another advantage is that once we drop the deprecated options,
converting the remaining things will be easier, because we obviously
don't need to add the compatibility hacks.
Using this mechanism is separate in the next commit to keep the diff
noise down.
|
| |
|
|
|
| |
And remove the difference between the aliases. This is needed to make
the sub-option changes less painful.
|
| |
|
|
|
| |
This is a bit "special", because the config tree wants unique
m_sub_options pointers in the whole thing.
