Add an infrastructure for collecting performance-related data, use it in
some places. Add rendering of them to stats.lua.
There were two main goals: minimal impact on the normal code and normal
playback. So all these stats_* function calls either happen only during
initialization, or return immediately if no stats collection is going
on. That's why it does this lazily adding of stats entries etc. (a first
iteration made each stats entry an API thing, instead of just a single
stats_ctx, but I thought that was getting too intrusive in the "normal"
code, even if everything gets worse inside of stats.c).
You could get most of this information from various profilers (including
the extremely primitive --dump-stats thing in mpv), but this makes it
easier to see the most important information at once (at least in
theory), partially because we know best about the context of various
things.
Not very happy with this. It's all pretty primitive and dumb. At this
point I just wanted to get over with it, without necessarily having to
revisit it later, but with having my stupid statistics.
Somehow the code feels terrible. There are a lot of meh decisions in
there that could be better or worse (but mostly could be better), and it
just sucks but it's also trivial and uninteresting and does the job. I
guess I hate programming. It's so tedious and the result is always shit.
Anyway, enjoy.
I think that makes more sense.
And also remove the graph from the total cache usage, since that wasn't
very interesting. So there's still a total of 2 graphs.
That's where it comes from after all. The other property does not have
much of a reason to exist anymore, but there's no real reason to remove
it either.
Previously, EGL as provided by a pkg-config was checked for independently
in several places. The effect this had is that --disable-egl would not
actually disable EGL from the build, as this only affected the "egl" option
relied upon by egl-x11. wayland-gl and egl-drm did their own EGL checks.
By making wayland-gl and drm-egl depend on egl instead, we fix this
behaviour and can simplify egl-helpers a bit, as we can now simply
check whether egl or one of the other features providing some non-pc egl
is enabled, instead of checking every single thing that might be pulling
in egl.
Future work could make the "egl" option just be a catchall for any
EGL implementation, so that brcmegl and angle and Android can piggyback
on the egl option as well.
Ancient Linux audio output. Apparently it survived until now, because
some BSDs (but not all) had use of this. But these should work with
ao_sdl or ao_openal too (that's why these AOs exist after all). ao_oss
itself has the problem that it's virtually unmaintainable from my point
of view due to all the subtle (or non-subtle) difference. Look at the
ifdef mess and the multiple code paths (that shouldn't exist) in the
removed source code.
I wonder what this even is. I've never heard of anyone using it, and
can't find a corresponding library that actually builds with it. Good
enough to remove.
It was always marked as "experimental", and had inherent problems that
were never fixed. It was disabled by default, and I don't think anyone
is using it.
May or may not help when dealing with playlist loading in scripts. It's
supposed to help with the mean fact that loading a recursive playlist
will essentially edit the playlist behind the API user's back.
Scripts such as the OSC can be loaded and unloaded at runtime by
toggling the option that enables them. (It even works, although normally
it's only used to control initial loading.)
Unloading was racy because it used the client name; fix this.
The load-script change is an accidental feature. And probably useless.
I mostly intend this for internal purposes. Probably pretty useless for
external API users, but on the other hand trivial to expose. While it
makes a lot of sense internally, I'll probably regret exposing it.
This time is set on every seek (but when initiating it). A new seek
longer than 2 seconds after this is counted as separate seek for the
sake of the revert seek command. If a seek takes a bit longer, this
removes time from these 2 seconds. This commits resets it on the end of
the seek. (Doing anything special for seeks that take longer than 2
seconds is out of scope of this commit.)
Until now, it used only coordinates clipped to the screen for this,
which meant no negative margins were ever reported to libass. This broke
proper rendering of explicitly positioned ASS events (libass simply
could not know the real video size in this case.)
Fix this by reporting margins even if they're negative. This makes it
apparently work correctly with vo_gpu at least.
Note that I'm not really sure if anything in the rendering chain
required non-negative margins. If so, and that code implicitly assumed
it, I suppose crashes and such are possible.
The "rule" is that a fallback warning message should be shown only shown
if software decoding was used before, or in other words when either
hwdec was enabled before, but the stream suddenly falls back, or it was
attempted to enable it at runtime, and it didn't work.
The message wasn't printed the first time in the latter case, because
hwdec_notified was not set in forced software decoding mode. Fix it with
this commit. Fortunately, the logic becomes simpler.
There's no more need to call mp_lua_PITA to get the ctx, and the
autofree prototype is now enforced at the C level at compile time.
Also remove the redundant talloc_free_children at these functions
since it's now freed right after the function completes.
Also, rename auto_free_node to steal_node_allocations to be more
explicit and to avoid confusion with the autofree terminology.
Advantages of this approach:
- All the resources are released right after the function ends
regardless if it threw an error or not, without having to wait
for GC.
- Simpler code.
- Simpler lua setup which most likely uses less memory allocation and
as a result should be quicker, though it wasn't measured.
This commit adds the autofree wrapper and uses it where mp_lua_PITA
was used. It's not yet enforced at the C level, there are still
redundant talloc_free_children leftovers, and there are few more
places which could also use autofree. The next commits will address
those.
Looks like the recent change to this actually made it crash whenever
audio happened to be initialized first, due to not setting the
mux_stream field before the on_ready callback. Mess a way around this.
Also remove a stray unused variable from ao_lavc.c.
Lua changed behavior for this specific event. I considered the change
minor enough that it would not need to go through deprecation, but
someone hit it immediately and ask on the -dev channel.
It's probably better to restore the behavior. But mark it as deprecated,
since it's problematic (mismatch with the C API). Unfortunately, no
automatic warning is possible. (Or maybe it is, by playing sophisticated
Lua tricks such as setting a metatable and overriding indexing, but
let's not.)
Travis is currently having "problems" and is spamming IRC all the time
with pointless failure notifications. Make it so that it hopefully sends
a message only when it goes from success to failure, which should
exclude these cases.
While I'm at it, I'd like to complain how idiotic it is to store CI
configuration in a project's source repository. Such a repository should
only contain things that are inherently part of the code's function, not
part of the organization. You don't store bug reports, build results,
the website, developer access controls, etc. in this repository either.
But for CI it's supposed to be OK? I'm all for this "configuration as
code" thing, but what it should mean is that you store configuration
files in some git managed repository, NOT necessarily that you dump them
into the main source code repo. There are many arguments why it should
not be there, such as this very commit. I have a feeling this is mostly
just because all these idiotic web services just want to advertise their
shit and bind customers by not giving easy ways to treat source code and
CI service configuration orthogonal. And so, the source code repo gets
clobbered with stupid shit (both in the set of files and the commit
history). It's fairly idiotic and my tolerance for it is waning. (Oh, of
course you could probably jump through hoops to make it a separate repo,
but I bet that is complicated and has all kinds of downsides because it
won't be the way "it's meant to be used".)
The VM could throw at pushnode and before mpv_free_node_contents, which
would have resulted in leaked content.
Now this case is handled without leaks.
Note: the lua code still leaks on such case, but mp_lua_PITA doesn't
have destructors like the JS autofree has, which, specifically here,
can do mpv_free_node_contents. So TODO: enhance the lua PITA code to
behave more similar to the JS autofree.
Move some parts that can be generic to the client API code. It turns out
lua.c doesn't need anything special.
This adds the "id" field. I think this was actually missing from the
JSON IPC code (i.e. it's a very recent regression that is fixed with
this commit).
Both Lua and the JSON IPC code need to convert the mpv_event struct (and
everything it points to) to Lua tables or JSON.
I was getting sick of having to make the same changes to Lua and IPC. Do
what has been done everywhere else, and let the core handle this by
going through mpv_node (which is supposed to serve both Lua tables and
JSON, and potentially other scripting language backends). Expose it as
new libmpv API function.
The new API is still a bit "rough" and support for other event types
might be added in the future.
This silently adds support for the playlist_entry_id fields to both Lua
and JSON IPC.
There is a small API change for Lua; I don't think this matters, so I
didn't care about compatibility. The new code in client.c is mashed up
from the Lua and the IPC code. The manpage additions are moved from the
Lua docs, and made slightly more "general".
Some danger for unintended regressions both in Lua and IPC. Also damn
these node functions suck, expect crashes due to UB.
Not sure why this became more code instead of less compared to before
(according to the diff stat), even though some code duplication across
Lua and IPC was removed. Software development sucks.
Unfortunately, merely changing the playlist current position affects the
flags returned by the "playlist" property, so the entirely thing needs
to be marked as changed. Seems to be a design mistake.
Should give a good deal more explicit control and insight over the
player state.
Some feel a bit pointless, and/or expose internal weirdness. However,
it's not like the existing weirdness didn't exist before, or can be made
go away. (In part, the weirdness is because certain in-between states
are visible. Hiding them would make things simpler, but less flexible.)
Maybe this actually gives users a better idea how the API _should_ look
like, too.
On a side note, this tries to really guarantee that mpctx->playing is
set between playback start/end. For that, the loadfile.c changes assume
that mpctx->playing is set (guaranteed by code above the change), and
that playing->filename is set (probably could never be false; was broken
before and actually would have crashed if that could ever happen; in any
case, also add an assert to playlist.c for this).
playlist_entry_to_index() now tolerates playlist_entrys that are not
part of the playlist. This is also needed for mpctx->playing.
