At least on my machine, reading back the frame with system memcpy is
slower than just using software rendering. Use the optimized gpu_memcpy
from LAV to speed things up.
Pretty much a fringe-feature, but also it's awkward if something appears
on the terminal with no indication for the source.
This is made quite awkward by the fact that stderr and stdout could be
closed at different times, and that poll() doesn't accept "holes" in its
FD list. Invalid (.e.g negative) FDs just make it return immediately, as
required by the standard. So sparse_poll() takes care of the messy
details.
What was the purpose of that? Probably none.
Also simplify another thing: if we get the cancel signal through FD,
there's no reason to check it separately.
We need to manually define the flag since we are using a separate identifier
for each of the Lua checks. This was done before 9b45b48 by the composed check
with a define_key (see waftools/checks/generic.py).
The pkg-config check was the only one to not redefine a define key because Waf
already does that automatically when we call the generated function with the
same identifier as the generator function. Now if they are called with two
different arguments we will get two different definitions.
Fixes#1218
No development activity (or even any sign of life) for almost a year.
A replacement based on youtube-dl will probably be provided before the
next mpv release. Ask on the IRC channel if you want to test.
Simplify the Lua check too: libquvi linking against a different Lua
version than mpv was a frequent issue, but with libquvi gone, no
direct dependency uses Lua, and such a clash is rather unlikely.
The immediate mode (which is the default) uses a tiny ringbuffer and
doesn't grab timestamps. This leads to quite bad behavior due to the
fact that there's an additional buffer between playloop and TV code (the
demuxer thread, which doesn't exist in MPlayer).
Always grab the timestamps and use a decently-sized buffer. I still have
no clue what I'm doing, and hacked it until it appeared to work. Report
regressions if you experience any.
I can't believe how shitty this (MPlayer-derived) code is. Maybe it
should be fixed or be replaced with using libavdevice, but that doesn't
seem worth the effort.
Anyway, for now reduce the time it's blocking to wait for new frames
from 10ms to 1ms, because 10ms might be a bit too tight: it could
deliver the frame up to 10ms late - now it's only up to 1ms. (And yes,
it does that instead of using condition variables. It also abuses
volatile variables as atomics. It's hilarious.)
stream_rar.c peeks the first few bytes when trying to open, which means
that opening any stream reads at least 2KB of data (internal buffer
size) on opening. This broke --stream-dump, which saved only the data
following this initial buffer.
Hack it around by writing the current buffer to the capture file too,
and move stream_capture_write() above stream_set_capture_file() for this
purpose.
Cleaner solutions might include: handling the terrible rar thing
differently, or using the "proper" stream API for dumping. (The latter
is not done, because --stream-dump shares code with the --stream-capture
misfeature.)
Fixes#1215.
Apparently if resizing a NSWindow from a secondary thread Cocoa will
automatically protect itself using NSViewHierarchyLock and in our case,
cause a deadlock.
Fixes#1210
Although this is fine when the stream cache is active (which caches
these and returns the result immediately), it seems cleaner not to
rely on this detail.
Remove the update_cache() call from demux_thread(), because it's sort
of in the way. I forgot why it exists, and there's probably no good
reason for it to exist anyway.
It's needed for some obscure feature in combination with .rar reading.
However, it's unconditionally used by the subtitle loader code, so take
care of not blocking the main thread unnecessarily.
(Untested.)
So a client API user can know when a window is created or destroyed.
Also might be useful for the OSC: it could disable itself if video is
disabled.
Before this commit, there were only indirect ways of detecting this.
Most things should be allowed to access the client API unconditionally
(for example for sending events), so move destroying the client API
down. Also, mp_uninit_ipc() should happen before the point at which all
clients are shutdown, or there will be a small time window in which new
clients can be created after destroying them all.
Wether and when the text of a button should be squeezed when it
gets too long can now be configured in the layout:
lo.button.maxchars = <number>
nil = no squeezing (default)
If the button text has more than <maxchars> characters, it will
be squeezed to the estimated width of <maxchars>.
Doing that doesn't make sense anyway: it's meant for interactive input,
and if the output of the player is not on the terminal, how will you
interact with it?
It was also quite in the way when trying to read verbose output with
e.g. less while the player was running, because the player would grab
half of all input meant for less (simply because stdin is still
connected to the terminal).
Remove the now redundant special-casing of pipe input.
The player was supposed to exit playback if both video and audio failed
to initialize (or if one of the streams was not selected when the other
stream failed). This didn't work; for one this check was missing from
one of the failure paths. And more importantly, both checked the
current_track array incorrectly.
Fix these issues, and move the failure handling code into a common
function.
